i got it working but using both cards at the same time results in a system hang everytime after about 5 mins of run time

see the heatsink nexto the cpu socket ,this was getting super hot so i added a fan hoping it would cure the system hang now the heatsink stays cool to the touch , but i still get the system hang after a few minutes
i even tried disabling the onboard video , and sticking a geforce 6200 in the 3rdslot and using that so i wouldnt have to use the onboard or zotac cards for video
was hoping i could load these machines with the cards but looks like only 1 per machine will work properly or atleast be stable
