    Default Help me overclock on EP45-UD3R

    What do you think about this OC:




    Setting on BIOS CPU Vcore to 1.3v, in Windows shows 1.264v

    Your comments would be appreciated

    King Regards.

    Looks fine except maybe a bit high VTT(CPU Termination).
    Passed any stability tests and what kind?
    Post a screen capture of MemSet main(click >>) and SPD(click spd) windows for comments about possible improvements.

    IBT results are pretty low, though I don't know what to expect from a Pentium processor.
    Try to set Static tRead Value(Performance Level in MemSet) 1-2 steps lower, might improve memory performance a little bit, if it's possible.

    IMO any settings should be set to as much as needed, not more. VTT is still within specs for both CPU and MCH, no problem, you may just not need as much that's all. My current OC is still with 1.2v. Of course different processors and boards may need different settings.

    I would try with 1.2v

    Give it 8+ hours medium data set to be sure it's stable.

    Looking good, as said above at 350 FSB you may be able to use a lower tRD (Try 6)

    About VTT:

    -I set VTT AUTO in BIOS and the value was 1.5v
    -So, I set VTT to 1.2v (is the default value for E5200?) and I will test the stability now.

    Nice to see 6 worked for you, sounds good. I did not expect 5 to work as you found out, that is why I suggested 6.

    Looking good, have you tweaked things anymore? About Vtt, you may need a bit more than 1.20 for full stability since you are overclocked so high. So if you have issues try 1.25-1.3 and see if that helps any
