Probably
So on air, managed to get two cards crunching. No overclocks or anything just testing things out. Been folding for 24 hours or so without incident.
This is on XP32 which is the current OS and was the same for Seti and Folding before. So no need for dummy plugs.
Using GPU Core 1.31
With 4 GPU's its only using 256MB of main memory. I was worried it was going to eat RAM but it seems not to be the case at least on 32Bit XP
Going to try and get 3 running which is as many as I can fit on the mobo with the stock coolers on. So its a bit hot with GPU's reaching 70°C
Overall output is 29K-30KPPD
Then going to try some other OS's as I have bought some resistors to make dummy plugs.
Don't freak out about me using server OS's the machine will be doing dual service as a cruncher and backup storage device (ver low usage)
So in order of testing it will be:
XPx32 (current)
XPx64 (maybe if I have trouble with the server OS's)
W2K3 x64
W2K8 x64
Also I thought server as I may run the headless linux vm image for CPU crunching to max out the return
