So, I did a little tweaking to my hardware last night; added a 1000w PSU (it was free) and a Quadro FX 3700 (also free) just to see what was going to happen with it. Well it was a catastrophe
First, when I finally re-booted the system (after not completely plugging in the 8-pin aux CPU power at first
) FAH came up. Now, my board has 3 PCI-e slots. Top and 2nd have GTS 450's, and the bottom x4 slot has the FX3700. So, when I finally restarted the system, FAH saw my CPU, but then found ONLY the FX3700. Then, when I would try to manually add GPU slots, it would still continue to put the FX in the GPU0 slot :-\
2nd'ly (this is incompetence) adding the FX card made windows install a 331 driver...I didn't realize that until this morning when my PPD on the 450's was down from almost 8100 to 6400
Oh yeah, that was for the ONE 450 that actually was folding...the one in the top slot decided it was just going to fail 27 WU's
I did some oatchwork this morning (driver 327.23 (or something like that)), got the slots all folding. This is the practice run for adding a "real" 3rd card to this system.
Should I have uninstalled FAH before adding the 3rd card, then reinstalled? I don't understand why it "found" the GPU in the lowest slot on my MOBO as the "main" card.
