    Thanks, but unfortunately, I do not have those four options that you listed in the BIOS.

    You do not see Termination or Vtt? But you do see GTL_REF?

    Well if so, the GTL_REF is Reference voltages, so they should be set according to the vtt or termination voltage. IF you cannot set Termination voltages yourself then you are best off to leave the reference voltages on AUTO

    They only need adjusting after 450-500 FSB anyway, Auto will work fine and automatically sets them accordingly to what I suggested which is 64%, and 67%
    CPU Reference = CPU GTLREF1 and should be .64% Of Vtt / Termination
    CPU Reference2 = CPU GTLREF2 and should be .67% Of Vtt / Termination

    I see neither of those two. This isn't exactly the most detailed board, BIOS-settings wise.
    Well since I don't want to go over what I'm already at, I'll leave the CPU GTLREF settings at Normal (there is no Auto, I've checked).

    You are the one you told me you had those options, and you just said you would leave them on Auto.

    Sorry if you misunderstood what I tried to clear up above, maybe I said it unclear

    CPU GTLREF IS CPU Reference Voltage just named differently, there is two of them.

    So you do have it, I was just showing you what the name can be stated as, and how they should be set if you take them out of auto/normal

    And you can leave them on Normal and they will use the above % values anyway.

    Sorry to have confused you

    No need to apologize. I at least had some idea of what CPU GTLREF 1 & 2 do.

    It is still kind of early days, but I think your advice on what to do has worked. I'll still test with Assassin's Creed of course (unpatched then patched). IF anything happens I will uninstall the game for good and get the reliable PS3 version.

    Ah well I felt I should, since I thought maybe I confused you more. Here is some indepth reading about those if you really want to learn it all >>>

    And
    Adjusting A/GTL+ Levels for Increased FSB Signaling Margins and Overclocking - The Tech Repository Forums

    Good luck with your games, sorry I cannot help more in that area. But it is likely drivers or driver conflicts

    well how far do you want to OC your rig... I'll just recommend some settings for 3.85GHz, which your box should do no problem if its got god cooling.

    You can probably go even further with that OC, you'll just have to increase the FSB slowly and keep the vcore in line with that

    As much as I wish my GA-EX38-DS4 had that many options, there would be so many to understand and adjust (or not).

    Luckily, the ones I have are fairly simple and to the point. The OC is still being sustained, and the PC is still being turned off periodically (pc longevity as well as thermal paste break-in).

    With some Cvars adjustments, I've found Crysis plays quite well in DX10 at Very High and 1680x1050. As for Assassin's Creed, I am still hesitant about reinstalling it to check if it goes stupid again.

    Sorry to double-post, but I needed this to appear at page one.

    Lsdmeasap, I am tempted to test for 3.4ghz and then 3.6ghz with my setup now (not sure 3.8ghz would be possible though). It has been almost a week or so since I made the correct adjustments for 3.2ghz and nothing has happened to the system (it hasn't been on 24/7 though).

    What do you suggest I change to reach 3.4, and then 3.6? Feel free to suggest changes for 3.8 but I'm not sure it would work on my board (FSB wall).
