    So GTLREF2 is simply for the second die of a quad?
    Have you tried +0.05 vtt?

    I can't work that out yet. Some ppls say 1 is data and 2 is address, while others say 1 is dual and 2 is quad. For the result the second seems likely, and may not be incompatible with the first description anyway.

    The thought of .05 had honestly not occurred to me. I have been playing with 454fsb, and noting that MCH stays same as 445. With GTLref in play does not need raising.

    .05 That would leave way more than .1 between vcore and vtt.

    OK. I'll see what LinX says about that, if it boots.

    I see min vcore is 1.31 so less the 0.1v difference under load.

    EDIT: but of course you may need to readjust GTLREF again

    Oh well, LinX said no. Lin something 64.exe stopped working message as well as out of memory.

    Was just re-reading the overclocking guide sticky where LSDmeasap tells Merman that fsb overvoltage control is not vtt, and that we cannot set vtt on our boards, that its auto and hidden.

    OK. That GTLref setting let me use lower fsb overvoltage, and lower mch. vtt unknown.

    Just researching stuff, noting interesting bits.

    GTLREF1, GTLREF2.

    Since X38-DQ6 BIOS F6 (any version), along with F7 and now the F8 series, those two options were included (only seen when pressing Ctrl + F1 in the main BIOS menu to unveil hidden options in sub-menus such as M.I.B). So far it seems that those two options have the purpose of controlling the Vdrop by augmenting the CPU voltage when under load, which in turn helps drastically decrease the actual Vdrop. And we're indeed talking about Vdrop here, not Vdroop which is quite different (a deliberate choice from Intel).

    Vdrop is a lower voltage (generally read under Windows by a monitoring software) than the one selected in the BIOS, and it is different for each type of motherboard.

    Vdroop is a specification by Intel which modifies the voltages (usually lowering it) when the CPU is under load; that voltage difference is made to protect the CPU when it goes from an "under heavy load" status to an idle status.

    The hidden features of the GA-X38-DQ6 only and directly act upon the Vdrop.


    ---------------

    Also, according to what I've read about it, the only thing that has changed with BIOS F8C and F8D with those two features is that the first one, namely CPU GTLREF1 received a new default setting and is now set to Auto with the Optimized Defaults. But from the various posts I've read from that discussion forum there were reports that it should be set to Normal instead of Auto to ensure maximum stability, and to use the Auto setting only if experiencing (after all necessary stability tests) instability issues that wouldn't fit the usual "stable" settings (in other words, if your settings should be stable but aren't, then try to set it to Auto instead, like the new default suggests).

    That is what I've found about those two hidden features. I myself am currently setting them both to Normal and everything, so far, looks absolutely stable.
    Also in an early x38 bios GTLREF1 was -3%.

    Looking through the Clunk x38 blog and x48T living review: The C2D range used
    Normal/Normal
    -3%/Normal
    -3%/-3%
    -6%/-3%
    -6%/-6%

    Beyond Normal/Normal used after low 450's fsb

    CPU/PCIEX Clock Driving Control :
    This setting controls the PLL output to the CPU & NB. I found, like others, that 1000mv was good for the quad.
    If anything is incorrect, please post alt info?

    Maybe he changed his mind since.

    OK. I'm convinced.

    E8400 + X48 (Gigabyte) overclocking - Finding the maximum FSB - Overclockers Forums

    Very informative article. It resulted in:



    Really I have only been testing 4.22 and 4.3, so there is a chance that 4.275 might need 50ps CPU Clock Skew.

    Temp was 27C again today. No blue screens for 4.3GHz.

    It "feels" good. Not a particularly quantifiable quality, but it does. (Not claiming total stability, as testing is incomplete, but looking good so far! (How many times have I read that? Oh well.)

    profJim,
    The vga psu is outside the case, but does not seem to make a difference.
    I read Conner's threads. Any more good ones? I read a lot.

    4.37GHz @ 460fsb - My ram wouldn't do 1104MHz - blue screens on login. I didn't raise ram voltage for 1104, just AUTO settings. Should I volt them above spec?
    Now using 920MHz on 2B strap, tRD 10. SuperPi-10.8, best at 1090MHz was 10.73.
    did an hour of small fft's, now doing large, at ambient 25c as first check. Into second set now.

    EDIT: Computer says no right now, so 4.3 it is. Don't want to raise cpu voltage for higher temps with current cooling. Funny how a combination can boot into Windows a few times and then become unstable and bluescreen next restart and fail with settings put back to last success as well. There are other combinations to try, but will let the board and OS "stabilise" a bit before tackling it again.

    LATER EDIT: Maybe the player intro to FarCry2 is a stability test. I've always had glitchy gameplay in FC2, and the taxi-drive intro would crash once or twice before making it through to the game. Tonight it sailed through without a stutter, and I think I had the first bug free FC2 gaming session in ages. So then I think what other games are buggy, and the Battlefield1942 mod - Battlegroup 42 came to mind, as it had often crashed with the texture load during the intro. That played a lot better, with no loading glitches. Very happy making, especially at 4.313GHz.
