Overclocking memory divider problem

Paulieg · Mar 19, 2007, 12:48 PM

I currently have my Opty 165/ LP Ultra D overclocked to 2.73 at 1.45v stable on Orthos prime for 12 hours and OCCT for 8 hours. Memtest stable for 4 passes. My temps are very good for air, as I do not break 46c on full load. So, I'm thinking of raising my voltage and overclocking further. Here is my problem: I currently run my memory divider at 150 (5/6). I think a higher overclock on this divider will start to cause problems with my OCZ Gold XTC DDR400, as its already significantly overclocked at 2.9v. For some reason, I cannot set my divider to 140, 133 etc. If I lower the divider in Bios below 150, windows will not load, and the computer will restart. Anyone else have this issue? Any suggestions?

sounds odd that, i have a quite similar setup (but with ocz performance, and a foxconn nf4sli) and havent had any trouble with bios dividers, however if i want to change ram divider in windows ive been using a64info, as ive had a64tweaker crash a few times(even downclocking)

I've tried those programs, but I need something that will hold in bios, or my system will not boot. Anyone else?
