Dual GPU setup with Win 7
Alrighty, time to put out more numbers. I'll be putting in the second GPU tomorrow. This guide still valid even though it hasn't been updated in a while? Anything I need to know other then this guide?

It was pretty simple for me (after the first hurdle anyways)....
I set mine up the same way as having one card... I just had an extra folder for the additional client and put the -gpu0 and -gpu1 in the clients additional paramiters, works great.
Here was the thread I did...
Folding on dual GPU's windows 7
Don't forget you need a monitor or dummy plug in each card...

I have a little issue.
The second card is running great. Brought my windows experience up to 7.8
However, I can't specify -gpu0 or -gpu1 as an additional parameter. I just created a second GPU folder copied the install file there and proceeded to setup the GPU. Under the 'Additional Paramenters' in the 'Advanced Options' section is where I'm specifying the second gpu....well, trying to specify it that is.

Not working....i'm getting an unstable machine error on it. I fixed the parameter issue.

SLI is disabled in the control panel. The bridge is still on the card. I'm using the latest drivers 191.07. I have two monitors. One monitor is hooked to each card.

Ok, I'm stumped. My original video card is the one that is failing. I deleted the work unit it on and got nothing. here's the log

Did you edit the original gpu folding to put -gpu0?

What's weird is the I shut down the my original gpu client when it was at 28% complete. When I restarted it I started getting the issue.

Does it happen when you only have the one gpu going? Overclocked at all?
November 10th, 2009, 11:23 PM #12
yep, if I disable the second gpu my original still fails.

Bat, I had the same problem. It is -gpu 0 not -gpu0. Need the space between the -gpu and the 0 (zero).
Be sure to also give them diffrent machine numbers. I kept 1-8 for the cores and used 9,10,11 for the gpu's.

The parameters were spaced to begin with and gpu already had a different id number. I'll work on it more this weekend after exams.

I figured out the problem. It's not me at all. It's the card.
right now the card is down clocked.
I'm mad but oh well. I'll see if I can return it but if not, GT300 is getting closer. That thing should hopefully put out 18k points min.
