New here, first post. I switched from a e8400 to a Q9550 since Microcenter had a sale for $169, in the process, Abit IP35Pro took a dump. So, picked up a GA-EP45-UD3P after reading reviews. Overclocking is a little more complex on P45 chipset. After looking through forums, I have the settings below. I have ran prime 95 for 2 hours with no issues, as well as OCCT.
Normal temps around 36-40, and 55-60 under OCCT load.
I tried to go to 3.8 (8.5 x 450), and BSOD'd during OCCT. I think my memory may be limiting me. Any thoughts or suggestions?
