Folding at home on your computer

Out of curiosity, does anyone else out there use your computer to fold proteins for this project by Stanford University? I started just recently so i've been curious whether there are actually other people doing this. Since my laptop uses so little power, I don't really mind using it to run this program in the background as it automatically stops the minute I do something that needs the cpu cycles. If it costs me a few cents a day, it doesn't bother me as it seems to be for a good cause. Unless I need the cycles, it generally loads my CPU at between 45-50% load and keeps them running at a core temp of 63-64 degrees C which is normal for my Turion 64 X2 Ultra.

If you don't know what i'm talking about, this is the team that I am folding for at http://www.hardfolding.com

I hear that you can also use your PS3's to do this stuff as well, although i'm not sure how it will be affected by the latest update no longer allowing for other OS'.

I did it years ago when SharkyForums were actually active and stuff. I haven't in a long time though. I wonder how it would work with Windows 7. I think Nasa has some sort of similar program as well for people who are so inclined.

I am currently running the uniprocessor version and it is actually running perfectly in the background on my laptop as I type this. I am considering running the GPU one as well since it isn't like my GPU is being utilized while I am working on an excel file. My laptop has Windows 7 x64 Home Premium on it. I havn't decided whether I will run my new desktop or not. In general, I don't like running computers without a battery(like my laptop) while I am not around as power goes out in my neighborhood more often than I would like. Usually, it is some drunk prick hitting a pole or a tree falling on the lines as the Emerald Ash Borer Beetle has left a swath of dead trees.

I heard there is something Nasa is doing, but I would rather have my CPU cycles going towards solving problems like Alzheimers and stuff.

With this latest update that removes the Other OS option, will you still be able to Fold proteins for it? How many points per day does that thing give you?

I noticed that there are a lot of distributed computing projects out there, which is interesting since I used to always hear about Folding proteins and never really knew what it was. Now that i'm involved, it appears to be for a good cause as this is a field where scientists know so little even today. It almost seems like this DC stuff is almost a giant hobby as there are people who are literally running server farms at their own expense to fold proteins and stuff. Hate to see what their electric bill is!

Accurate simulations of protein folding and misfolding enable the scientific community to better understand the development of many diseases, including sickle-cell disease (drepanocytosis), Alzheimer's disease, Parkinson's disease, mad cow disease, cancer, Huntington's disease, cystic fibrosis, osteogenesis imperfecta, alpha 1-antitrypsin deficiency, and other aggregation-related diseases.[5] More fundamentally, understanding the process of protein folding — how biological molecules assemble themselves into a functional state — is one of the outstanding problems of molecular biology. So far, the [email protected] project has successfully simulated folding in the 1.5 millisecond range[6] — which is a simulation thousands of times longer than it was previously thought possible to model.

The Pande Group's goal is to refine and improve the MD and [email protected] DC methods to the level where it will become an essential tool for MD research,[7] and to achieve that goal they collaborate with various scientific institutions.[8] As of January 13, 2010, seventy-two scientific research papers have been published using the project's work.[9] A University of Illinois at Urbana-Champaign report dated October 22, 2002 states that [email protected] distributed simulations of protein folding are demonstrably accurate.[10]

You can also go to the direct website which is

http://folding.stanford.edu where they have a good description of what they are trying to do with this DC project. The team I fold with is http://www.hardfolding.com .

The program simply runs in the background and is designed to give any other program priority access to the cpu so that it never bogs your computer down. While my dual core laptop is idling or browsing the internet, i've noticed that it puts roughly a 50% load on both of my cores. The program will automatically download work units to simulate, and then uploads it when it finishes and then grabs a new work unit.

A very dear family friend died from Creutzfeldt-Jakob disease a few years ago. And that's something the [email protected] program is looking to cure. So you've inspired me to reinstall [email protected] on my computer. It's on pleanty of time when I'm not using it and I definitely have a good amount of processor power left.

That leads me to a question, would anyone else be interested in doing this seriously, and should HDF have a team?

I am currently folding for team #33 if you would like to join over at the hardfolding forum. I don't know if there are enough people interested to start our own team, although starting our own team would definately be awesome if enough people wanted to join. If you want, the DC forum that we participate is over in the DC computing section of the Bits and Bytes section at hardforums which you can link from the main page.

I am currently pulling about 600pts per day with my laptop running. If you have a multicore processor, you may want to run the SMP2 client although it is much harder to setup.

It takes forever to do it with the PS3. Maybe a six hour shift for one? It used to give you random numbers. One time it estimated me four hours and once it estimated me three days. I leave it on when I'm watching TV and the PS3 is just sitting there. I also leave it on because of the music option. I have a ton of MP3s and it'll play them randomly so if I'm cleaning up or playing Wii (since the wii doesn't use the surround sound) I can have music on while folding. I'll look for more specific stuff later.

I ran the GPU last night and it did 10/500 that seemed a bit slow, but I also noticed my PC was in standby mode this morning so maybe it's shutting down in the middle of the night. I won't leave it on during the day. I'm using the GPU one. I'll have to check into it when I get home from work.

Yeah, my laptop was doing the same thing until I went into power management and turned off the option in Windows 7 where you can set the inactive time delay before it goes into sleep mode.

I think your speed just depends on the size of your WU. My laptop has been working on one since yesterday and is only 85/500 done on this one. The previous one was 2500 and it got done in just 5 hours. Since you are running the GPU client, it is very possible that they are sending you more intensive and bigger WU's than someone like me who is running the classic uniprocessor client. The other thing is that I think you can run the CPU and GPU client together if you have a good multicore processor. I'm not running it on my new desktop as my computer room literally gets hot enough without running that beast full time.

It's working fine, I read the number wrong, it's not 50,000 it's FIVE HUNDRED THOUSAND... that's a much bigger number. They apparently gave me a huge file to fold. It must check your connection and your specs to see what your system can handle. My computer has 13 days to hand it in, it's gotten 20% done in 3 days, shouldn't be a problem.

From what I understand, GPU clients and SMP clients get bigger work units than those running the classic uniprocessor client. You could try running both and really rack up those points. My laptop must have been given a really huge WU as it is still on that same one and is now only at 300/500.

Well, i've got the SMP client running fulltime on both my laptop and desktop now. It wasn't as scary as I thought, and is actually nicer running the console than the GUI. With my desktop's all 4 cores at 100% utilization, I think it is pretty clear that I need a new cpu cooler as that thing sounds like a dust buster when it starts spinning past 5000rpms. Because my room temps are high, i'm not comfortable with those temperatures either as they are easily reaching 57-58degrees C. Those Deneb cores are rated at a maximum temperature of 61 degrees C. No game has ever caused my Phenom 965 to reach those kinds of temperatures, but I guess games very seldom utilize all 4 cores at 100% full time.

I have just now underclocked my video cards and am considering running the GPU client except I am trying to see if I want to produce more heat and increase my electric bill like that.

I have set my laptop to 65% cpu usage as temps are approaching 70 degrees C. The laptop has a Regor core based Turion 64 X2 Ultra which is rated at a maximum of 72 degrees C.

3 days = 20% then 15 days =100%

X4 and higher multicore users can actually run both the GPU client and the SMP client at the same time to boost their output. The problem with running the GPU client on an SLI or Crossfire setup is that you have to do some stuff like remove the connecting bridge, and do some modifications to the configuration stuff. I suppose I could just use one video card, but that would still generate more heat than I want, and would also likely jack up my electric bill. We'll see how serious I get into this folding stuff as I just started a few days ago and am trying to learn the ropes. It is only 72 degrees F outside and I i've already got the a/c in my computer room running on full blast as it really gets hot up here.

If this folding thing becomes my next hobby, you'll probably see the feds raiding my house because of a spike in electric usage. I am supposed to get my income tax stuff back from the accoutant this week, and I might build a box just for folding if I get more back than I expect.

FWIW, buying a little 250 GTS just for folding wouldn't be a bad idea.

I don't know how ATI GPUs with DirectCompute match up, but there was a time when CUDA rules the [email protected] world. I know in 2008 Any Nvidia GPU with CUDA could beat any ATI GPU period. Don't know if that's changed, a simple google search didn't provide me with much either.

BOINC appears to be another DC project that many people are doing, and the ATI cards outperform the nVidia cards by a HUGE margin from what i'm hearing. However, I hear that the Folding stuff is less stable on nVidia stuff, but is much faster because of those CUDA cores. From a watts of electricity/point ratio, people say the GTS260 is the sweet spot if you are trying to get the most points for every watt of electricity you use for Folding.

Well, I don't know what i've gotten myself into since I have really gotten bitten by this folding thing that I am doing. But I am getting ready to have a new rig put together that will do nothing but fold 24/7 and my preliminary decision may shock the hell out of a few of you. The sad truth is that in folding, Intel dominates and AMD isn't even closely in 2nd place. Because the Core i7 has 8 virtual cores, it will actually allow you to fold -bigadv work units that are far more productive than the standard SMP WU's. Otherwise, I would need a dual cpu motherboard for an AMD solution since even the upcoming Thubans are only 6 cores. Here is what i'm possibly looking at right now

GA-X58A-UD3R LGA 1366 X58 ATX Motherboard
Intel Core i7 930 that will get overclocked
Noctua NDH-12 SE2 or Cogage TRUE cpu cooler
6 gigs Corsair XMS CL8 ram
some cheap WD HDD
my old Coolermaster case from the previous old rig
some really cheap PCIx video card
Windows XP x64 or Linux :eek:

I don't know anything about Folding really, but if you got a CUDA gpu could you do two separate folding applications at the same time? One on proc and one on gpu? Of course the proc has to run the GPU, but surely it has enough extra room to do a little folding of it's own right?

That is correct as you can run both the CPU based and GPU based client simultaneously. In fact, you can run as many GPU clients as you have video cards. Some of these hardcore folders on my team are literally running 3 -4 video cards that are all totally different models on the same computer.

The problem though is that once you start getting into multiple GPU's, you have to start worrying about the power draw and heat generated. Doing that long enough may keep the points coming, but it is going to suck when the electric bill comes. Right now Fermi is unable to fold because of a problem with the current GPU client as it isn't compatible. Once they release a 480GTX compatible client, Fermi is going to be a total MONSTER for those who are willing to deal with the heat, noise, and power draw. The estimates I am seeing put Fermi at roughly 17k-21k points per day which is what an overclocked Core i7 puts out if you run the bigadv experimental work units.

The GPU client does require a little cpu power, so what the Core i7 and massively multicore people are doing is locking CPU affinity where you might have 7 of the virtual cores of an i7 doing nothing but folding, and you lock the 8th virtual core to do nothing but cater to the GPU client. I'm still trying to learn the ropes with this folding thing, but boy we are talking geekiness to some exponent of some exponent. I think I am getting so into it because it is so exciting in this way.

Because of how your points are calculated, you are given a number of points for completing a work unit and then given a bonus based on how quickly you finished before the bonus deadline. The only reason you would want to fold with a GPU is if the GPU generates more points than what you will lose from the cpu no longer being able to finish a WU as quickly. The guys who are running GTX 275's and above are raking in some serious points with the GPU clients.

I believe there is one person folding on a Magny Cours setup with a total of 24 cores and I believe I read this person is doing some insane number of points per day.

Kam, you have a GTX 275 right? Have you thought about joining in and Folding for a Cure? You can read more about this at http://folding.stanford.edu and I fold for Team 33 which is the HardOCP team at http://www.hardfolding.com.

Your GPU combined with your Phenom X4 oc'd to 3.8ghz would generate some serious points. In fact, your GPU would trounce what your AMD can do. My 965 oc'd to 3.5ghz brings in about 7000-8000 points per day. Just your GPU alone would do almost 10000 points per day.

1. I'd rather donate whatever cash I would spend on the extra electric bill and save the wear and tear on my parts. Has anyone done the calculations to see if Folding is more efficient than cash donations at an equal ratio (using cost of added power draw to determine cash donation)?


2. My two charities are the Multiple Sclerosis Society and Child's Play. I don't think I can afford a third.



But for the 'cheap PCIe' card you're planning on putting in, you might as well buy the least expensive CUDA unit. IIRC, you can go all the way down to an 8400GS, but for the money a 9800 or 250 my be the best bang for your buck. I don't know for sure.

amdgamer
04-17-2010, 11:30 PM
I think this has become a huge hobby. Also while Stanford has said that they would appreciate any cash donations, what they need most of all right now are CPU cycles. The last figure I saw is that there are 400k active folders throughout the world right now, and that is what a DC project is all about. It is about everyone pitching in and contributing any spare computer cycles they can to tackle a project that otherwise wouldn't be remotely possible even with a bunch of super computers.

I am not a scientist so I don't really understand this whole process of protein folding. However when a protein misfolds, it is responsible for a number of diseases. To do these simulations, it requires computing power that no amount of money could do at a college.

There are all sorts of DC projects from that SETI stuff to some wierd prime number calculations, but I decided to get involved with this project because I personally don't give a horse crap about whether there is life beyond earth, or whatever big prime numbers they are trying to find.

I believe the sweet spot is around what you just stated GPU wise when you look at a points generated per watt of electricity. I just don't want to get involved with a GPU because some people have stability issues, which may have something to do with how they are boosting their bus speeds and other things like crazy to obtain their insane, but stable Core i7 overclocks.

Yes. That is because any DC project could not exist without the collective cpu cycles that make is possible. That is why most of us go with the most efficient rig possible, in that they purchase hardware that generates the most points per watt of juice. That is partially why i'm seriously considering a Core i7 as it 2.5 times more productive than a Phenom X4 while both have very similar TDP's. Thuban would have been interesting, but the fact that it doesn't have the 8 virtual cores of a Core i7 still disadvantage it. Also as I said, this folding thing has become a huge hobby as well. Back when I was into nothing but horsepower(my previous Chevy had over 520hp), I was willing to accept the fuel economy consequences.

Kam, they don't need your money, they need your 2,000 dollar computers CPU cycles. Yes, if you were to spend 300 dollars doing it this year, you could theoretically give them 300 dollars instead and save wear and tear. But, by using your computer you are giving them something more valuable, Data they need to cure cancer.

I personally think both are good. I support 3 different charities myself. Childs Play, The Recreational Fishing Alliance and I donate a project every year for Housing Works, which is a New York City based Charity. (That one is more because my customers make me)

Regardless, a few extra CPU cycles for cancer is okay too. I feel everyone should do something, but you can't do everything.

Well I spent a lot of time last night finding the right overclock and my new dedicated folding rig is up and running finally!

I am a bit disappointed at the overclock as the max it would do is 3.67 ghz on the Core i7 930. The problem is that anything over that wouldn't POST without me upping the voltage significantly, which created a serious heat problem with the processor running over 90 degrees C even with this beefy cooler.

I let it run A3 work units all night long, and it is still running fine. People use Prime95 to stability test, but it just doesn't put the loads on the cpu like folding does. Several guys on our team have ran Prime95 for a full 24 hours only for their system to crash after a couple hours of folding. So to sum it up, 3.67ghz(175bus speed x 21multi).

Voltages are

1.2685 cpu volt, 1.275 QTI volt, IOH on auto, and Vdimm at 1.60 volt

Temps are in the upper 70's and low 80's.

Yeah, from what I was reading you're going to have to up the volts something fierce on this chip to break the 3.7 ghz wall.

Have you seen that HSF on the new Gulftown 980x sex cores? Talk about a beefy factory heat sink! However the regular i7's just don't have a setup that is really that good with high voltages.

I think I got mine stable, but it is still running hotter than I would like as it is hitting the low 80's. Once summer comes, I am definately going to have to downclock as this won't be good over the long run. I hear that the 930's are insanely overclockable, but the only people I see hitting those clocks are the ones water cooling. Even then, the efficiency of these i7's really drop off after about 3.7 ghz. At 4 ghz, Tomshardware found that the Core i7's are drawing over 412 watts. That would make my poor Antec 550w PSU scream for mercy.

With the warm weather starting to settle in I really need to get a new case. If you think about the power the i7s have, 4ghz by 4xcores (8 virtual) higher clocks (was it 10-20%) if you kick in Turbo Mode, 412W doesn't seem to high haha. And Watt per clock, they'd still beat an AMD in price ratio!

Don't forget that AMD's Phenom II X4 965's actually overclock very well. They also come with a pretty decent HSF from the factory, although very noisy. I have also never seen a Phenom draw the kind of power under loads that a Core i7 draws. 412watts under load is an insane number, and I don't even want to know what will happen if you also happen to add dual Fermis in SLI to that rig.

From my personal overclocking experience along with what others say, it is also best to leave turbo boost mode off in the bios if you go above 3.3ghz as it really screws things up.

Thuban should overclock and scale very well if you keep the heat under control. With 6 actual cores, I am curious to see how well they will do in folding. I love the fact that my motherboard just released a new bios and is now compatible with THuban.

Well damnit............turns out my 3.67ghz overclock is NOT stable as I found my system to be frozen and hard locked when I got back from Chicago. I noticed that the system had apparantly been frozen for 3 hours according to the last entry in the folding logs. I've kept the voltages the same, but have downloaded to 3.57ghz to see what happens :mad:

Seeing how well everyones 930's are overclocking, I must have a dud.

Well the folding rig is now getting moved over to a new case as it has become clear that the current classic Cooler Master case is totally inadequate for the firebreather called the Core i7 930 Bloomfields. Heat and stability problems with the hotter weather have forced me to downclock as low as 3.46ghz(165x21). Unfortunatly, we are not in summer yet and Core Temp was reporting temps in the upper 80's which is getting way too close to the ragged edge. These Bloomfields are actually capable of easily approaching 100 degrees C, but that doesn't mean all that heat isn't going to do something bad to the other components inside the computer.

As of now, everything is getting moved to a Cooler Master HAF922, and i'm switching out the old Antec 550 watt for a new Corsair modular 650 watt PSU. At least now i'll have enough headroom to possibly run a GPU client as well on this rig at a future point when I have money again. I am also upgrading the fan on the Cogage to a 76cfm silencex, and am adding an external Enermax 76cfm fan to blow through the side panel right onto the cpu. Maybe this will allow me to do up the clocks again.

why not just put a water cooler system in at this point?

Heh, i'm extremely risk adverse. Liquids and electronics just arn't supposed to mix in my mind, and a possible leak would be a total disaster. I did eye the Corsair H50 that they had in stock at Micro Center, but it is not as effective as the best air cpu coolers. The Corsair setup is actually one of the only maintenance free setups on the market and is very popular among the casual overclocking crowd.

A full blown water cooling setup would just cost too much money unfortunately. This recent upgrade wouldn't have even been possible if I didn't have a $100 gift card to MC.

The other thing i'm looking at is maximizing production from the folding rig while minimizing electricity usage. A liquid cooling setup will allow for much higher overclocks to be possible, however the Core i7 Bloomfield cores have insane power draws at higher clocks. At 1.40 volts or more, Tomshardware recorded powerdraws on the i7 920 and i7 975x at over 400 watts. All of this heat also has to go somewhere and my rooms are also hot enough without me producing even more heat.

Well just picked up my folding rig from Micro Center and I have to say that the case was definately the culprit. With the temps lately, the i7 was starting to hit the mid and even upper 80's. Running without the side panel on the case reduced temps by 5-6 degrees. With my new case, it is now running 10-12 degrees cooler with it hitting only the upper 60's with the overclock in my sig.

Time to start cranking up the voltage again now that i've got heat under control :devil2

Dust, not to mention I don't feel comfortable running a computer without anything to shield it. With the warmer weather, I did try running with the side panel off, although it wasn't as good as this new CM HAF922 case. Either way, problem is solved now as the cpu is running only to the upper 60's even with a room temperature near 80 degrees F.

Once I get done playing FFXIII, i'll probably go back to playing with voltages since I have some breathing room with cpu temps now.

Since we have a couple of folders here, I thought i'd post this. Looks like another paper has been published from the folding at home project.

I'm not a biochemist, so I have little clue what is being talked about. However the 2681 bigadv project was used to study how the flu virus infects or something like that.

[email protected]'s 73rd peer-reviewed research paper was published today, in the journal PLoS Computational Biology. This paper used results from the p2681 -bigadv project, and is titled "Atomic-Resolution Simulations Predict a Transition State for Vesicle Fusion Defined by Contact of a Few Lipid Tails". The paper contains research on the process of Vesicle fusion, which is involved in the infection of cells by viruses, the transmission of impulses between nerve cells and cellular secretion.

The summary of the paper is as follows:
Membrane fusion is a common underlying process critical to neurotransmitter release, cellular trafficking, and infection by many viruses. Proteins have been identified that catalyze fusion, and mutations to these proteins have yielded important information on how fusion occurs. However, the precise mechanism by which membrane fusion begins is the subject of active investigation. We have used atomic-resolution simulations to model the process of vesicle fusion and to identify a transition state for the formation of an initial fusion stalk. Doing so required substantial technical advances in combining high-performance simulation and distributed computing to analyze the transition state of a complex reaction in a large system. The transition state we identify in our simulations involves specific structural changes by a few lipid molecules. We also simulate fusion peptides from influenza hemagglutinin and show that they promote the same structural changes as are required for fusion in our model. We therefore hypothesize that these changes to individual lipid molecules may explain a portion of the catalytic activity of fusion proteins such as influenza hemagglutinin.

Where does the PS3 rank in Folding?

Intel i7<PS3<260gtx

Actually PS3's are really really really really horrible in points generation. We have many PS3 folders on our team because they believe in the science, but you won't see any point whores go buy a PS3 just to fold with it. Point generation was actually very good back when the PS3 first came out as 900pts per day was considered good. However, the type of work units changed along with a bonus point system for time sensitive work units on the PC being introduced. Production wise, your list would be Intel i7>=AMD Thuban X6>260GTX>PS3.

i'd imagine the new i7's (or core i9's as some call them) would top the chart,

The Intel Core i7's are good at production, but total beasts if you can get a good overclock on them. It is just the superior nature of Intel's Nehelem architecture. Some overclock better than others as mine refuses to be stable past 3.46ghz unless you crank up the voltage to a point where it needs water cooling. Others on our team have I7 930/920's that can hit almost 3.67ghz on near stock voltage.

The latest Gulftowns(980x X6's) are just total monsters. Folding is a very heavily multi-threaded application, and the Gulftowns just gobble up work units when overclocked. We have several Gulftowns on our team that get insane production for a single processor rig. It will be very interesting to see what happens as rumors point to Intel releasing a Gulftown derivative with lower clocks and 6 full cores soon.

What is more interesting is that AMD is back in the game again ever since they released their Thuban X6's. With folding being heavily threaded, it has allowed AMD to produce similar to a Core i7 as having 6 physical cores makes up for the fact that it has a last generation architecture. We have several Thubans on our team and they overclock like there is no tomarrow. One guy with a 1055T is running at 4.2ghz with nothing but a Corsair H50.

Better computer cooler, or better cooling for your house? If you are worried that your computer will run too hot folding, you can always turn down cpu utilization percentage when configuring the folding client. For instance, I have the SMP cpu client on my laptop configured to 55% cpu utilization as it will hit over a coretemp of 72 C otherwise. My laptop has an AMD Turion 64 X2 Ultra based on the Regor core.

My folding rig doesn't have any cooling problems thanks to that Cogage. Looks are definately deceiving as I never expected it to perform so well at the price it sells at. My a/c broke yesterday and the house is at 87 degrees F right now, and my 930 has not hit any temps higher than 74 degrees C.

Well, I will hopefully be adding another folding rig by this Wednesday as Micro Center is building for me folding #2. It should net some impressive production as i'm hoping to hit some impressive overclocks. It will be featuring a Coolermaster HAF922 case, Intel Core i7 980x Gulftown, Cogage TRUE Spirit cpu cooler, 160gb Western Digital hard drive, HIS ATI Radeon X1550 pcix card, 6 gigs of Corsair DDR3-1600, and a Corsair 650 watt PSU.

This was part of my entertainment budget that was being saved to buy a Colt or S&W .357 Magnum revolver. I decided to build another folding rig instead of buying another gun(currently have a Glock 9mm). It also helped that I had like $200 in VISA rebate cards that wern't spent yet from my folding1 build and my gaming rig.

When I saw pricing for the 970 X6, it broke my heart as I was actually hoping that Intel was going to release an affordable Gulftown. For an extra $100, the 980x is the clear choice as you get a better piece of silicon that is unlocked.

The bad thing is that while the Gulftowns run fairly cool at stock speeds, they really get hot when you start overclocking them. This Cogage cooler is not cutting it as I don't dare go higher than 3.63ghz right now. I was able to hit 4.1ghz, but Core Temp showed that my processor was hitting the mid to upper 80's. It is one thing to fry a $200 i7 930, but I just don't want to risk frying this Gulftown. Right now at 3.63ghz at stock voltage, i'm hitting the upper 60's which is where I like being at. I used the Intel burn test for all stress testing. It seems to get my cpus running 10 degrees hotter than using Prime95 to stress test.

The only thing i'm trying to figure out, is that my folding performance seems to be fluctuating. My temps are under control, but my time per frames are 2:11 a few frames, then drop to 7 minutes for the next few. I turned off power management and disabled Windows Defender, so i'm not sure what might be causing this to happen.

We have one person on our folding team that is running that monstrosity known as the Noctua NH-D14, but it doesn't look like it would fit in my case. It is also a bit heavier than I feel comfortable as i'm still not convinced it is safe for the motherboard PCB to be dangling that much weight.

The Noctua NH-12-SE2 will fit, but i've seen a few comparison tests that show the Cogage outperforming it. The Cogage looks unsubstantial, but it is really an incredible cooler and is why nearly everyone on our team runs it. It is almost the unofficial cooler of our team.

I thought I would post that the folding program is getting ready to yield another academic paper and that there have been some significant advances in the knowledge of protein folding.

From the desk of Vijay Pande:

Two New Key Results
August 30th, 2010

We have two papers (one that just came out in PNAS and one that's about to come out in Physical Review Letters -- papers #74 and #75 on our papers list) that we're particularly excited about. They represent some key results that we've learned by examining multiple results from [email protected] The resulting picture of how proteins fold is fairly different from the prevailing view, so it will be interesting to see what experiments tell us about the specific predictions made within. We're excited to see where this goes!
