    I am currently at 3.825Ghz right now.

    450mhzx8.5
    vcore: 1.325
    CPU PLL: 1.65
    CPU Term: 1.24
    MCH Core: 1.3
    DRAM: 2.1

    Everytime I try for 4.2GHz, or even just 4GHz, I always have issues. There are so many different voltages instead of just the basic CPU, RAM, FSB, and NB to worry about now...

    Currently I use Intel Burn test for 100 runs on Maximum, if that passes I run Prime for a bit just to double check. 3.8 Passes both just fine, 4GHz fails after just 2-5tests. I just don't know what to change because I try what I used to do for overclocking, but there are to many variables now:bang:. Any help?

    Look here and here. There's a lot of good info in there, pay close attention to Gampamu's GTLref settings.


    Also, E0 or C1? What cooling you have?

    Here is what i found on the net cant remember from where, this is for 4GHZ on P5Q Deluxe. works very very well, i havenĀ“t tried more than 4ghz(and i will not try:banana: )

    Good luck!

    E0, where would me GTL settings be?

    Also I will look t your table more when i get back home.

    yeah look at these threads and lower that cpu pll. that high a cpu pll should be unnecessary and is creating more heat

    Ok, I will lower my PLL, I am using Water cooling. Also I do not see any GTL voltage options like I did on my 750i. Are you talking about the reference voltages? cause I have a MCH ref and a CPU Ref.

    Dude, we have reeeallly similar systems, I just caught that.

    lol, except u made it to 4.1 GHZ :p. I havn't had more time to work on it yet, tomorrow I should be back here with more results. However! I have retested 3.8 with 1.55v PLL instead of 1.65 and it has passed successfully.

    You'll get there, and earn some gray hairs in the process. That board will do anything you need it to. I almost went on a rampage while doing mine.:chainsaw2:


    A note, I did end up having to settle on a slower RAM speed, cuz the MCH doesn't like some dividers, so keep that in mind, I bet you'll have trouble with that. My RAM will do 1330 easy, but the divider to get there won't work, with only that change, the board says "eff you".

    Another note, I saw you have 4GB RAM, is that 2x2 or 4x1? 4x1 will limit your OC, and 2x2 won't clock as high as 2x1, but really, RAM speed is not that important. Just get it the highest it'll do with that board and be done.:nerd:

    Well it seems to be happy right now at 3.9Ghz )460x8.5) with ram at 2.40B (1110mhz) which is 2x2GB, used to be 4x1GB but.... my poor crucial tracers died on me :( so no more pretty lights. If this god for saken test finishes I will inch it up a lil more, see how close i can get to 4 before i need to increase any volts.

    I had forgotten i got to 3.9 before, but my RAM didnt like being at 950mhz (DDR2 800, now i have DDR2 1066).

    Ok, test have finished, 3.9 (460x8.5) is good to go, however anything above 465FSB requires more voltage.

    You need to cut down on the IBT runs and increase the amount of time on your Prime95 blend test.

    15 to 20 passes at max is more than enough for IBT imo. Prime95 blend overnight or around 8 hours is the sweet spot!

    See thats the thing, for 4GB of ram, 100 tests, 2GB; 50 tests. I have always held a grudge against Prime95 and always hated using it. I wish i could still use Orthos but can't get it to work on quad cores. Prime takes way to long, and can fail after hours, waste of time IMO. Orthos was 2 hours, IBT is 100 tests and I am good :). If my CPU can hold at 100% in IBT (which really really burns it up since in Prime it gets to about 55C, where as IBT gets it to 68C) for 100 tests, which is about 1.5hrs, I think it can deal with the stuff I put my CPU through on day to day routines.

    no way around not using p95 prime blend 11hrs. that stresses cpu, ram and chipset. IBT only stresses the cpu... 10 runs on high or max is more than enough for IBT. IBT is good for on the fly testing because its so quick though. you can still use orthos beta open 2 instances of it and choose cores 0,1 for one and cores 2,3

    ugh, i f'ing hate P95... why does it take so long?! I tried orthos with affinity for cores 0,1 and cores 2,3 but it never worked. Always flooded the display with some error, idr what.

    I think I will just stick to 3.9 right now, room gets hot enough as it is.

    Phantom93 can you post all settings from your bios enhancement menu? I'm at 3.58Ghz now, would love to get 3.8 or 3.9. Thx :)

    Not meaning to nick your thread but what rev is actually better for overclocking? mines E0..

    supposedly E0 is the best.

    @Strangelove: I will post it later, need to go to bed :S
