so,

I have just started folding, and I can get a PPD of 2000, and so I tried adding another gpu (8400gs) to my system for more power. My dc 7900 would not let the pc boot (it did post). does anyone have any suggestions?

 

also, how good is 2000 PPD?

My rig: r7 1700 @ 3.9/1.35v, 16gb ddr4 3200, assorted rando SSDs, hx 1050, vega 64 1650/1025

You need SLI, which the card and the computer don't support

SLI is only used for gaming.

well nvidia dont run at 4x by the looks of it that motherboard is 16x/4x(not sure of the old nvidia card is the same),

if you want to run 2 nvida cards it must be at least 16x/8x

lives on

What do you mean by "It will POST but it doesn't let the PC boot"? Does it throw up an error or what?

 

Also, is this the CMT or SFF model?

the second gpu is a 8400 gs on a 1x slot....

I bought the pc for $20. I bought it a gt 610 for $48 and it works fine on its own. I want to add the other card just to help with my PPD on Folding@home

just reinstall windows, easiest method probably

 

the error code, if it helps is amt error 2232

you don't really need to worry about that, amt is just out-of-band management (this is a business-class machine)
