So, i havent done a whole lot of tinkering with my OC passed 4GHz. i have tried a good few configurations of voltages on the NB, FSB, and CPU, but i havent really pushed it super hard since most of the time i end up coming back empty handed. now, i havent tinkered with it in a while, and im sick, with a second working computer, so i have a stupid amount of free time on my hands. my question is simple, is there anyone out there who runs a GA-EP45-UD3P with a Q9550 or Q9650 with 4x2GB of DDR2 (im using 1066 G.Skill), that found lowering the memory divider down a notch or 2 (it's currently set so im getting 1068 @ 2v 5-5-5-15 with 445x9FSB). my cpu is a Q9650 running at 445x9 FSB @ 1.325vcore (1.296vcore actual) with LLC enabled. cooling isnt what i would consider a limiting factor, though the CPU does run at about 73c under linpack, but i cant afford better cooling. is it possible that i might increase northbridge stability for higher overclocks with all 8GB intact. i use a ton of ram on my system, easily exceeding 4GB, so it's not worth loosing the ram to increase the OC. i would however benefit from the increase in clocks, due to the amount of audio encoding im doing right now.
