GPU EUE Solution?

One of my two folding machines is running the GPU2 client on a 8800GT. I often get EUEs that result in the client going offline for 24 hours at a clip.

My question is: Will a new GTX 460 fall prey to this same issue?
 
That's a tough question to answer. It all depends on what is causing the EUE.
If it is shaders pushed too far, drop shader clock. If it is heat, drop core and shader clocks.

Post some more info and the log and let us take a look at it. Include your clocks on the vid card as well as temps. Lets trouble shoot the problem with the 88GT and then go from there.

no most likely not.. if the 8800GT is EUEing then its probably near the end of its life.. especially if your running stock clocks..
 
My 8800GT EUE's a few times a day sometimes. All tests have shown the card to be ok so I assume I just get bad WU's. Run memtestg80 which you can get from Stanford just to make sure it's not bad gpu ram and try a clean driver install also.
 
Gigabyte GV-NX88T256H (Type B; Zalman HSF)
65nm 8800GT 256MB
Purchased New from NewEgg in July 2008 (~$77 after MIR)
Stock Clocks: 700/1700/1400
Temp while folding: 72C

I have tried underclocking the core/shader/mem with no change in EUE's. I have taken the core to under 500MHz and the shaders down to 1200MHz or so. The GPU has seen no video games, only folding almost continually for two years counting.

The computer in question is running Windows 7 Home (64bit) with the following main hardware:

Asus M4A89GTD PRO/USB3
4GB Corsair XMS3 DDR3 PC1600
AMD Phenom II X3 720 Black Edition
Gigabyte GV-NX88T256H
640GB WD Black HD

The computer is setup for 24/7 GPU folding, but it also serves as a secondary computer that my wife uses for photo editing, web browsing and email. Most of the time, it is just quietly folding and checking email.

The PC hardware is not overclocked and the fourth core of the X3 is not enabled since it fails prime95 testing. The main computer hardware/software was built by me back in May (2010).

The computer as a whole is rock stable in spite any torture tests I have thrown at it (Prime95, Memtestx86, Furmark). The only anomaly is the F@H GPU client EUEs that I get on a continual basis.
 
For your actual question, my GTX 460 heavily overclocked has turn 150 units without a fail since the last time I rebooted close to 9 days ago. They seem extremely stable on GPU3.
 
Again, mine does it frequently as well...I've just gotten used to having to restart the client manually every once in awhile; same with my 260's although they EUE a lot less frequently than my GT does.
 
I have an 8800GT I had to downclock the memory to 600MHz in order for it to fold.

pvieh, I'm wondering if the low memory of 256MB on your card might be causing a problem. Depending on the WU, my 8800GT will use anywhere between 246MB and 275MB of memory.

Is there a VRAM memory monitoring utility that will work under Win7 64 bit? RivaTuner won't read my VRAM usage on this machine.

The GPU is working on project P6600 right now. 41% completed using 67MB of VRAM... 97 to 99 percent GPU load. 69C GPU temp, 44C PCB temp.

Now that I can monitor VRAM usage, I'll keep an eye on it.

I have also underclocked the VRAM to 600MHz to see if that helps.
 
Well, I EUE'd out again tonight. 25 completed WU's and 12 failures according to HFM.NET.
 
did you try cleaning out the case/fans? I see your reported temps look ok.... might help

I've got an EVGA 260 (already RMA'ed once) that just doesn't fold well ... even at stock speeds and underclocked with a solid PSU. My vague point is not all cards are up
the the challege. :(
 
I get EUEs sometimes, but never that many. Looking at my current HFM.NET stats, I've done 803 WUs across 8 cards with only 3 EUEs. If your temps are fine, then it sounds like you have a bad card.

You might see if you can RMA it, or if you want to use it for something else, a new card should not have the same issues when folding.

^^^This, i've run over 8000 WU across 6 GPU and have only had 6 EUE's. These were all caused by a clogged heatsink on an 8800GT, cleaned it and it was fine until it got retired.

However i just purchased a 2nd used EVGA 275/250 CO-OP card and that just constantly eue'd on the 275 chip, turned out to be bad ram. There are some cards out there that just won't fold for whatever reason, if its bad ram there is no fix available - it is time for a replacement:(
 
I've got my eye on this as a replacement for my 8800GT:

MSI N460GTX Cyclone 768D5/OC

The cooling on that card appears to be up to the task of 24/7 folding and if it gets rid of my EUE's, I'll be happy.
 
I also agree with the sentiment that "some cards just don't fold well"

I've had a few GTX260s and GTX275s that will fold for months without a single EUE.

I've had an 8800GT, 9800GT, and a couple 9800GX2s that would EUE at least once a week.

It would be interesting to know if any models in particular aren't up to the folding stress.
 
My 470 returns intermittent zero force sum errors when I do a lot of scrolling, open/close many windows, or display many images on the screen at once. It seems like most people with this problem are running Vista-64; I wonder whether upgrading to Win7 might help.
 
I have a MSI 460GTX Cyclone (768MB VRAM) on order as a replacement for the 8800GT. In the meantime, I have been crunching using the SMP client on the tri-core. Doesn't work as efficiently as the 8800GT (while it was working) or my aging Q6600...

More details to follow.
 
I have my 460GTX installed and folding away... HFM.NET estimates 9100 PPD.

36 WU completed, 0 Failures.

The old 8800GT is now in my Mint Linux box.
 
Excellent. I think you'll be happy with that 460
