Thread: MCH OverVoltage Control with 2x2GB RAM




  1. #1

    Default MCH OverVoltage Control with 2x2GB RAM

    Anybody that knows,

    TweakTown Member LSDMeASAP mentions the following in several posts:
    <style type="text/css"> <!-- @page { size: 8.5in 11in; margin: 0.79in } P { margin-bottom: 0.08in } --> </style>
    (G) MCH OverVoltage Control [+0.2V - 0.3V] << Needed for 2x2GB?
    But is it necessary if I'm not OCing?

    Thanks!

    Yes, that is most often necessary. You may or may not need +0.3 depending on your ram speed and timings, but +0.2 is very likely needed to be fully stable

    Cool!

    I'll go set it in a few.

    Thanks a lot Lsdmeasap!

    I'm not sure if you understand what Lsd says. It's not necessary but it may help if you have problems. My 2x2Gb 1066 RAMs run fine without it, some other people's RAMs do not.

    Thanks Nickel020!

    I like it at +0.2V (on MCH OverVoltage Control). I might try +0.3V in a couple days.

    With +0.2V my latency in DPC has improved. And so has the "+12V" Voltages in CPUID HWMonitor.

    And, its an enormous placebo. (jk)

    Well you want it set to the lowest you are stable at with the other settings you want to run.

    And I would advise you use Everest or EasyTune to check 12V voltages, or does HWMonitor show them correct now for P35?

    IDK if HWMonitor Voltage readings are fixed.

    How do I tell?

    If I try Everest's Voltage readings, where do I go in Everest to compare HWMonitor's Voltages?

    And thanks again Lsdmeasap... because my computer ROCKS at +0.3V (MCH OverVoltage Control). I'm unstoppable now!!! muahahaha!!!

    (+0.3V MCH repels enemy nades.hahahaha)

    And my CPU is only at 3.0Ghz!!! It's so stable I can quick-load and quick-save while playing Crysis- on Very High- to my hearts content. Even during the conclusion on the carrier! I Just finished it.

    Yep, Crysis refuses to crash!!! *Talk about three words I thought I'd never use in the same sentence for at least another two years. On "Very High" settings mind you.

    And thanks again Lsdmeasap!

    Default Re: MCH OverVoltage Control with 2x2GB RAM

    Well I said that about HWMonitor due to the fact that it often says 3.xx or so for the 12V rail.

    In Everest you go to, on the left side, computer, then sensors section

    Glad your PC is working so good for you, and thanks for the kind words

    Your welcome!

    Here's the comparison between Everest and HWMonitor:



    I wish Everest had Minimum and Maximum.

    Thanks again Lsdmeasap!

    Ahh thanks, well I see it now works for P35! That is good, I still dont think it works right in P45, but I have not checked for a month or so
