Unfortunately, that's the case, I believe that's why the PPD is ~1.5k-2k lower than 353pt WUs. If you get a 353 or 787pt WU, open up GPU-Z and let it sit for a bit, you'll see that it uses ~95% of the GPU continuously, giving higher PPD, but unfortunately also higher temperatures.

I'd like some help getting 2 GPU clients working in Windows 7 x64. 1 on the 8800GT, and another on the 9300. When I try running 2 clients (one per GPU) with a monitor per GPU, the first client (8800GT) folds fine, but even after over an hour there is no progress on the 9300. I know it is going to be slow, but when I was folding on it earlier it only took 6 minutes per % for 353 pt WU and 14 mi/% for the 787 (what I had now). Any suggestions/ideas appreciated

I assume you set the -gpu0 and -gpu 1 switches? If so, try erasing the gpu 1 switch, and replacing it with -local. I had issues like that on a mixed ATI/nV system, but with 2 different cards, it might be worth a shot.

I had set the switches, but I tried deleting the config files and reconfiguring and now it's working. Thanks!

What card are you running already? I may be moving some inventory very soon.

EVGA GTS 250. I also have recently acquired another 750i motherboard and will be looking for some cheapo cards (8800xxx or 9800xxx?) after I scrounge up a CPU and P/S.

Question for the gurus: I know about the -gpu0 and -gpu1 flags, should I keep the same machine ID number for each client?

Thanks in advance for your replies.

No.
CPU get's machine ID#1.
GPU-0 gets #2
GPU-1 gets #3
GPU-2 gets #4
GPU-3 gets #5
etc, etc...

 

[bogmali]

And while you're in the config menu, don't forget to set the -advmethods option to YES or just add it along with your -gpu 0 and -gpu 1 flags

Thanks guys. Time to hitch the mule to the plow. Wish me luck.

I'll try folding with my 8100 lol

 

[NastyHabits]

Got it working. Added a 9500 GSO. Only one problem, I get 0.00 for PPD listed in Fahmon. What's up with that?

 

[hat]

Wait a while. It needs to run a while so it can calculate the PPD.

Now I have a problem. I want to set up F@H like this... I want to have two folders, one for each GPU. The first folder is called 8100 and the second folder is called 9600. The shortcuts will be named GPU8100 and GPU9600, respectively. How do I know that the shortcut for GPU8100 is actually going to fold on my 8100 and not my 9600?

Because you will explicitly call the exe file in each separate folder with separate shortcuts to each. IE: c:\Program Files\8100\Folding@home-win32GPU.exe -gpu 0.

that is why you have the -gpu 0 -gpu 1 -local flags.
Will the 8100 show as the 1st GPU or 2nd? You could just set them like so
8100 -gpu 1
9600 -gpu 0

just watch fahmon if you do it that way. Say you are getting 4kppd on the 8100(that shouldn't happen) then you know you need to switch the flags. (switch the 8100 to -gpu 0 and 9600 to -gpu 1)

that is if you want to do it by trial and error

Hm... I think I figured out my above question (my 9600 appears to be gpu 0 and my 8100 appears to be gpu 1). I keep getting UNSTABLE_MACHINE errors on my 8100... why? How do I fix it?

Here's what happens

 

[NastyHabits]

hat-

Just a stab at your problem, but I just resolved and issue (250 PPD way down), by making sure I had divided the memory between each.

 

[hat]

Nah, if that was the case, then the gpu folding and my SMP folding client would be doing this as well.

did you extend the desktop to the 8100

 

[NastyHabits]

New question: How do I get EVGA precision to recognize the second GPU so I can overclock it?

IGP's hate F@H.....

 

[hat]

Nope, I'll try it

IGP's hate F@H.....

But F@H doesn't hate IGPs...

 

[NastyHabits]

I found a work-around (for now). I can use W1zzard's GPUTool to overclock the GSO since GPUTool has a drop down box. I set the card to 650 GPU, 1800 shaders, and 650 mem. Temp is at 67, but I don't dare go higher because I can't reliably control the fan with GPUTool. At 67C the fan is running at 55%.

 

[NastyHabits]

Just an Aside

The 9600 GSO folds slightly better than my 4850 at about on fifth the FPS potential. Amazing. I beseech the powers that be to please, please finish the new GPU client.

 

[hat]

did you extend the desktop to the 8100

Hm, it won't let me. I went to right-click desktop > personalize > display > change display settings. I clicked on detect and it found my 2 empty display connections, the unused dvi on my 9600gso and the unused dvi for my 8100. If I click on try to conenct anyway with vga, I get the option to extend the desktop. I click on apply and it looks like it's going to work, but when I click on keep settings, it reverts back to "display desktop on only 1".

Am I going to have to use the dvi/vga adaptor trick to get this to work? If so, anyone wanna send me one?
