View Full Version : What am I doing wrong?

I'm trying to set up a single gtx295 in Win xp 32bit.

I must be doing something wrong when trying to disable sli. I followed the sticky for multi-gpu folding above but can only get -gpu 0 in folder GPU1 to fold. When I try to get -gpu1 in folder GPU2 to open by clicking the shortcut created per the sticky I get a message that says my card is not capable or I have an incorrect driver etc.

When disabling sli can I hook my two monitors up to both of the DVI outputs or does one have to be connected to the HDMI output? I've not been able to try connecting one to the HDMI since I don't have an HDMI to DVI adaptor.

When connecting both monitors to the two DVI outputs I use the nvidia control panel to turn off PhysX and check the "do not use multi-gpu mode" button. Then click apply and ok. If I try to restart the computer I get a BSOD and another restart and have to boot using "the last known good configuration" option. This turns PhysX and Multi-gpu support back on again and the cycle repeats.

If I don't reboot I can get -gpu 0 in folder GPU1 to fold by clicking on the shortcut created per the sticky instructions but not -gpu 1 in folder GPU2.

Any ideas? Is it necessary to hook up one of the monitors to the HDMI output?

I know this can't be that hard since several of you are folding on GTX295s. It is surely something I'm overlooking or not doing right.

This is the version I'm trying to install: Folding@home-Win32-GPU-systray-623

bump... for CJ, I really have no educated idea bro... but the HDMI path you're on sounds like the right track to me.

I don't know if you have to have something plugged into the HDMI port in XP 32bit, but the 2 DVI ports go to 1 GPU, and the HDMI port goes to the other GPU.

Thanks for the bump harlam357.

@Torin: From my research I don't think it is necessary to have something plugged in to fold only when setting up. However, I did find that it was necessary to plug one monitor into the DVI and the other into the HDMI for some OS. I just can't find any setup instructions for 32 bit xp.

It would seem that everyone who has written instructions is using another OS besides xp 32. Linux is most likely over my head so I was going to try getting the card folding in Windows first. When I am sure there is nothing wrong with my card and gain a little confidence then get up the nerve to try Linux.

In the mean time I guess I need to round up an adapter from HDMI to DVI and see if I can get both sides folding.

I think there is a force nvidiagpu_g80 type command you can add to your second GPU's shortcut that should turn it on. But I don't use it, so I'm not sure exactly what it is.

Just a thought... in XP 64-bit using 181.22 drivers I had to add a dummy plug and extend the desktop to get my second (physical) gpu to work. Otherwise, I got the same error message CJ got.

Now that I think about it... I believe this to be the case with any of the 180.60+ drivers (basically any drivers that have the cpu usage optimizations).

I have not tried adding the force gpu flag to see if that would make it work without extending the desktop.

When you open the "Display Properties" window in XP and go to the "Settings" tab, does it show 2 monitors? And have you extended your desktop onto the 2nd monitor? Also does RivaTuner show 2 GPU's (0 and 1)?

One more comment regarding the directions listed in the sticky. Personally, I prefer to copy the "Folding@home.exe" file to both of the GPU directories, and set the "Target" location in the shortcuts as C:\GPU1 and C:\GPU2. That way you are not trying to run the same executable file twice with 2 different "Start in" locations.

I'm running XP x64 using the 181.22 drivers on both of the systems in my sig. I DO have the desktop extended to all of the video cards on both systems, but I do NOT have any dummy plugs installed. Of course, I'm not using multi-GPU graphics cards.

Actually a GTX 295 has 3 monitors per card. GPU 0 has monitors 1 and 2, and GPU 1 has monitor 3.

Though I understand that when you are running 2 cards, GPU 0 and GPU 2 are on card 1 and GPU 1 and GPU 3 are on card 2. I haven't verified that myself yet.

@Torin3: Initially I did see 3 monitors initially but thought I must have done something wrong. 1 and 3 were normal and 2 was grayed out. Upon restart all settings reset to sli mode.

I now have an HDMI to DVI adapter. If what everyone is saying is right that is the only way to hook up monitors to gpu0 and gpu1 if both DVIs belong to gpu0.

I've disabled sli and physx. Set RivaTuner to the correct settings with no overclock atm. I'll restart and see if the settings stick.... or not. Here goes!

Well, it looks like all of the settings stuck upon restart except multi-gpu mode and physx turned back on after a BSOD. A restart is not required when turning these off so since the RivaTuner settings stuck and I have both gpu0 and gpu1 showing I'll proceed and see if I can get both instances folding.

Ok, that didn't work so I'll try it Edward2's way.

That didn't work either. I'll try leaving the monitor on and plugged into the HDMI.

Looks like it is working now:clap:

It seems you have to leave the 2nd monitor plugged in for the 2nd gpu to be recognized...at least that is what is working for me.:)

At the moment and without overclocking the shaders it is doing about 10,800 ppd.:burn: This means that my card is workig properly...so one less worry.

Thank all of you for your ideas and willingness to help someone like me with no real computer background. Don't be suprised to find me back asking the same questions in 6 mos, or the next time the power goes out, because I forgot everything I just did.:rolleyes:

PS I'm afraid to turn off the 2nd monitor...maybe I'll try that tomorrow. Do you think it will keep folding if I turn the monitor connected to the HDMI gpu off as long as I leave it plugged in?

If you don't mind not seeing the BIOS boot screens, you can switch the DVI port over to a dummy plug, and set the HDMI monitor (Monitor 3) as your primary display. That way you will only need one monitor.
