Hello everyone, I just added a second Radeon 5830 to my i7 930 rig and am having issues overclocking my CPU, I used to be able to run it at 4ghz w/ HT on before I ran crossfire, now that I am running crossfire I cant get it above 3.5ghz or it will blue screen. I am assuming that my Corsair TX650W PSU isn't enough power? I read that my radeon 5830's each draw 175W and my i7 930 draws around 150, I am running 2 500gb 7200 sata drives, 1 cd/dvdrw drive, 5 120MM fans, 2x2gb ddr3 1600 memory and I think that's pretty much it other then my usb 3.0 external 2TB seagate drive, mouse keyboard, self powered bose companion 2 speakers (they suck) and a 27'' LCD @ 1080P and a 22'' monitor @ 1680x1050.
I am able to make it through 3dmark 11 with my video cards at stock and cpu @ 3.5ghz I am happy with my score, I get around 6800 in 3dmark 11 but I can't overclock my 5830 anymore which makes me sad because I had it running at 975/1200 and it was running perfect, now I can't take it over 850/1100.
Do I need a new power supply? I added everything up and it looks like its a little under 600W at load. Am I wrong?
