Hi guys,
 
Pretty much my problem is I cannot seem to set my memory voltage/timings to manufacture settings while having my CPU OCd to boot. If I just set my RAM timings down (1600 / 7-7-7-24) it'll boot fine but once I try to do any type of voltage changing and frequency change on the cpu my computer fails to boot, it will stay at a blank screen with my monitor saying DVI signal not found.
 
I have to clear CMOS to get it to work again. Vice versa if I try to OC my cpu itself it's fine but moment I try to put in my memory timings it all goes to black screen again. Upgraded to Bios 83 which didn't fix the issue. Any help would be greatly appreciated.
 
Specs:
i7 920
Win 7 x64

    Check and make sure your RAM command rate is set to 2T.

    Try Sajin's suggestion and if the problem continues loosen the memory timings a bit and retry.

    I think I figured out my problem. I forgot the multiplier affected RAM rate as well so when I had it at 1600 / 2:12 it over went manufacture specification. Dropped it down to 1067 / 2:8 increased my VCORE from default auto 1.25 to 1.3
    VTT same at +100 mv
    VDIMM from 1.65 to 1.625
    and Timing is still at 1T.
    Memory timings set to 7-7-7-24-88
     
    Have my frequencies at 20x175 (21 with turbo) for ~3.5 GHz with idle cpu temps at 37C.
    So far it seems to be running stable will report back on any issues.
     
    So now my question is my memory is currently running at 1402 MHz. How would I go about increasing it to ~1600MHz while maintaining a CPU 3.4-3.7GHz OC. Would I drop my multipliers to something say 18x195 (~3.5) so I can get 1560MHz on my memory?
