GTX 295, no dummy plug needed!

It seems that many have to connect the monitor to both sides of the sandwich to get 2 cores working. Anyway, first of all, I've never tried this on anything other than the 182.08 WHQL driver. I do have dual monitors but both are plugged to the DVI ports, so one side of the sandwich (the HDMI side) isn't connected to anything.

After I disabled multi-GPU mode, I went to display properties and saw three monitors, and of course I know that monitor 3 isn't connected to anything. However, I was able to enable it and extend my desktop to this non-existent monitor. Then I hit OK. The whole trick is that you only need to get it enabled but not necessarily connected to any physical monitor or even a dummy plug. Now I'm getting 15k PPD total with a 511pt WU and a 353pt WU.

I've attached an image below. Can some other 295 users out there test this out and see if it works? (182.08 WHQL driver + empty HDMI port)

EDIT: Method confirmed working - http://www.overclock.net/5729120-post15.html

Here are the instructions:

Quote:
1. Enable multi-GPU mode.
2. Disable multi-GPU mode.
3. Right-click on desktop and navigate to display properties.
4. You should now be able enable monitor #3.
5. Run GPU2 clients!

I've explored a bit more and found a more specific way to glitch the driver to do this. When I rebooted, it doesn't let me enable the nonexistent monitor 3 anymore, but after re-enabling multi-GPU and disabling it again, monitor 3 can be enabled once again. I'll make a guide after some other 295 folders confirm this trick.

I'll have to try this out in a bit. Mine was folding at almost 9k PPD on each core for the first few hours, then one core stopped working :|! I wasn't running in SLI, and I had dual monitors attached..I don't understand why one always stops after a while.

i cannot get all 4 gpu's to fold on my 2 295s.

i can get 3 out of 4 to run but thats it.

even then, the 3rd one craps out after a bit.

cards are not OCed at all. fan is at 75% and temps are fine.

nothing in the whole computer is OCed at all.

i keep getting EUE's and nans.

if i swap the 2 cards the 2nd card always behaves this way so its not the gpu's themselves.

any insight?

EDIT: im using vista 64.
