Hi, i have a little problem...
The psu i got is a CM Silent Pro 1000w / 80A . I thought it was enough to power my gtx480 SLi, but the power that goes on the 12v rail is 963w which is enough for the setup BUT if I want to overclock the gpu's.....It seems it is not enough. I bumped the voltage from 1050mv to 1138mv to attain 900mhz core and Windows automatically restored default settings.. Afterwards, I decreased to 850core 1125mv....was stable for a longer time but failed at the end. I Also get those random GPU Core downclock when playing: seems my video cards are downclocking to prevent any power issue ( i did modify the power mangement mode in NV control panel to see if anything changes, but in vain). I'm assuming the cards require more power. Btw, every component is very well cooled. The gfx's don't exceed 70C.
I would like to have your opinions, maybe i'm completely wrong... So What do you think? What seems to be the problem?
specs :
amd phenom II x4 965 BE oc'd @ 4ghz
8gb ddr3 gskill ram 1333mhz
gtx 480 SLi
nf750-g55 mobo
cooler master m1000
