I also have a dell precision m4300, has a c2d @ 2.4 and a Quadro FX 360M, 512M (256 dedicated).

I was wondering if i should use the SMP client? Right now I'm just using the regular client.

I tried the gpu client, but it said it couldn't find a file, i think it was called nvcuda.dll, or something like that. Nvidia file I'm guessing.

Did you check if you have a driver that supports CUDA?

On another note, i've got two instances running on my sig rig (outside of the GPU2 client, which has already begun with its fifth WU as i type this) , and the second core just completed its first ever WU after nine and a half hours, but when trying to send it says some HTTP error about not being able to connect to the server. It retried a couple of times, then gave an error saying that the server received a file of 0 bytes, and that it might have been a connection failure or a corrupt file (which i doubt, because it did verify locally and continue before).
The first core is at 92% at the moment, it's been busy for over 9.5 hours just like the second one, why is it taking THIS long per work unit? My laptop is at 14 percent with the SMP client (Turion X2 TL-60 2.0 GHz) with both cores folding according to the program... it shouldn't be that slow either, should it? it's been busy just as long as the above instances!

It might be different from what i read somewhere else in this thread, about 120 minute WUs, but this is really weird to me (although i'm just beginning on this, patience is NOT my thing, and if i read that others are getting short WU times, then why haven't i

It's on the High Performance client page at http://folding.stanford.edu/English/DownloadWinOther

EDIT: Is there any way to increase the PPD on some of my older machines? or atleast let them have shorter WUs or something? It takes 5 days and 18 hours to complete a work unit of which it claims to be doing 1500000 steps..

Hi, after reading through these forums I decided to participate in folding for Overclock.net using my desktop (sig rig), fileserver (stock E6600 & 8600GT), laptop (old centrino) and PS3. I'll check in with the OCN folding team as soon as I get into the team top 1000.

I don't intend to fold 24/7 with any of the machines I have because electricity is quite expensive over here, so all clients run in background while the machines happen to be on. This means that folding on my PS3 is more or less a gimmick because Life With Playstation cannot run as a background service.

I'm having some issues with the 8600GT though. After about 10 frames the client seems to crash. I get a notice saying "UNSTABLE_MACHINE". I thought it could be due to overheating issues, since my fileserver is completely passively cooled. The graphicscard came with an Accelero S2 prefitted by Club3D, without any fans. But even after installing a Yate Loon 120mm the GPU2 client keeps crashing. This applies to both the regular GPU2 client with viewer and the console GPU2 client (which I prefer).
I'm running this on an Intel DP965LT motherboard, stock E6600, 2GB Kingston ValueRam with heatspreaders, XP SP3; through remote desktop, there is no display connected to the 8600GT. Overall case temperatures are ~30 idle, ~40 while folding and other tasks (torrent, media server, file server). I can't get a readout on the actual 8600GT temperature readout from any source (tried GPUz, Everest Ultimate and nTune). I also have no means of underclocking the card, RivaTuner doesn't seem to recognize its 181.20 driver.
Is there anything else I can do to steer this card into the direction of the greater cause?

I have another question to which I am unable to find a proper answer. I've googled extensively and looked all over relevant websites. When I shut down my computer I know the running folding clients will be properly closed down, so I can continue when I boot up again. Is this also true for my PS3? Or should I leave it on while it's folding?

Thanks in advance! (rep will be given!)

The code makes checkpoints every few minutes, when you shut down the PS3 it will remember everything upto the last point. When you start it again it will then continue from that given point.

About the unstable_machine error: is the graphics card, ram or cpu overclocked? If so, set them to stock and retry, otherwise you could try testing the memory because even when it's a GPU2 client, it still kinda depends on the CPU and thus the RAM, even though the chance of that is pretty slim.

EDIT: Forgot to say this: Welcome to the fold!

Allright thanks Rep given!

The 8600GT is not OCd, or at least not that I'm aware of. The only thing that I can think of right now is underclock it through nibitor and flash it. I have some experience flashing 8800 GTS's, but it's kind of a drastic measure and I'm still looking for other ways of solving this.

I've attached an image of my card. I just noticed that it doesn't have RAM sinks, could this be the cause of the issue?

Strange, at stock speeds it should be sufficient.. it shouldn't give out errors like that...
How much room is there above each VRAM chip? Maybe you can try some ZM-RHS1 ramsinks or similar ones, if they fit!

Of course you do need to check for proper airflow through the case, a passively cooled graphics card needs lots of air running through its radiator..

RAMsinks may be a tight fit. Also, I've actively cooled the card now with a Yate Loon D12SL–12 @ ~36CFM as stated in the original post. This is to no avail.

Next thing I can try is stresstesting the GPU and establish wether the heat transfer from the GPU to the heatsink is sufficient. Perhaps it needs a reseating.


[edit]
I've taken the server off of the cupboard and hooked it up to a monitor and keyboard/mouse to see if I could solve some issues outside of remote desktop. I found out that GPUz gives a proper temperature readout (Everest and nTune still don't), remote desktop seemed to be the limiting factor here.
I've stress tested the 8600GT using 3Dmark06 in loops of 5-10 and learned that even while passively cooling, the GPU doesnt get hotter than 60C. This is in a closed, sound padded case, completely passive, no casefans, but removed the PCI expansion brackets for minor air circulation. Case temperature remains around 40C.
After about 45 minutes of looping the driver crashed, kicking me out of 3Dmark. I then went to underclock the GPU because miraculously RivaTuner also worked outside of remote desktop. The stock 540/1188/800 (core/shader/mem) were changed to 530/1200/800 (notice the slight overclock on the shaders to compensate), which resulted in a stable 45 minutes of looping 3Dmark06. I got impatient, so I started up GPU2 console and it has been running excellent for almost an hour now.

I realise that this information may seem trivial to any readers, but I'm posting this for those that encounter the same type issues.

[edit2]
Turns out the underclock doesn't stand after putting it back on the shelf and using remote desktop to control the system. To overcome this I flashed the GPU BIOS with a modified BIOS in which the underclock is integrated. Right now GPUz believes the new 530/1200/800 clocks are the actual stock frequencies. (This method is not advisable for novices)

[edit3]
The client crashed again while in remote desktop. Underclocking hasn't helped and temperature doesnt seem to be an issue. What is causing the GPU2 console client to diagnose my system as unstable?

With stresstesting for graphics, it takes an insane amount of calculation errors to actually cause a crash or error in the test, or to even cause glitches visible to the human eye. The GPU2 client isn't error-tolerant at all, so even a slight instability will make it crash.
What you did now is to make the client run even faster, as it uses the shader processors of the card! Try lowering that as well (this sounds like a fabrication error already if you ask me, it should be stable at stock speeds at all times, especially with those temps), it might start working for at least longer periods of time..
Even if it might work for days on end it might still throw out an error occasionally. I'd say that if you've got warranty, replace it right away to be sure, you never know..
