Folding Forum

I just switched over my folding rig from Vista Home Premium to XP Pro. I have two 9800GX2's, a Phenom II X4 940, 3GB of RAM. I also changed some of the programs that I now use to fold. I now use VMWare server 1.0.9 instead of 2.0. I'm running 2 instances of notfreds utilizing 2 cores per client, rather than running Ubuntu in the VM's. I am also running the GPU CLI client instead of the version with the nVidia Viewer. I have the same CUDA drivers installed as I did under Vista. I am using WinAFC to spread out the work of the clients across all 4 cores. My CPU is only at 1-3% with all the GPU clients running, and right about 100% with both VM's running.

I don't understand what's happening here. The last two days I was folding under Vista, I hit 25k each day. Now with XP I just hit 8,500 for today!! I really need some help here! Any and all advice is *greatly* appreciated!

Did you follow the GPU install guide on the fah web site? IIRC, it suggests setting the core priority for the GPU clients to low, while keeping the CPU clients at idle. You may have to play around with the VM priority a bit to give the GPU more resources.

And while you gave before and after numbers for PPD, you didn't indicate which clients were folding slower... SMP, GPU, or both? That information would help us to figure out the problem.

p.s. XP is not the problem.

I run XPpro for my 4x9800GT's and have been running 2x not freds vmSMPs as well, get 20k+ easy, think your vm's are the problem, you will need to use a priority setter to bring down their priority as they are probably squeezing out your gpu's, try stopping one of the vmSMPs and watch your gpu ppd rocket, if it doesn't it's another issue, but common things are common..
