Okay i've just gone out and bought myself a new conroe system and this is what is happening. I had 3500+, AN8-SLI, 2gPc3200, 6600GT 256 I have now E6300, GA-965P-S3, 2gPc5300, 6600GT 256(same card) I'm not getting graphics corruption when loading the card up with anything 3D. the stock clockspeeds are (500, 1000) but on my original AGP card they were (500, 900). When i clock the ram back down to 900mhz the corruption seems to go away but on my Athlon rig i don't get any artifacts at all. Would installing Ram heatsinks fix the problem? I have bought someone the 2xVF700-CU so they have 8 Ram heatsinks left over that i could use. I have a 120mm fan in the rear of the case exhausting air and one 80mm fan bringing air into the front. Air flow doesn't seem to be interupted at all as i've cable tied everything out of the way. I have a thermaltake 420w Truepower supply, Does not having all of the 24pins connected make a difference? my old one only needed 20 but this one requires more. Thanks in advance for any help.
