    OC experts needed - apply within

    Hi,

    I've been working on my E6600 + P5B Deluxe OC and I really need some help. I have been trying multiple things on my own and I'm not asking for hand-holding, but I would like to get this stable (no matter the OC) by Tuesday as that's when I have to call in to reactivate Windows (stupid activation).

    I am only partially stable at the settings below, but they are the closest I've come to any type of good performance. It will dual prime small fft for, I dunno, a long time, but one core will usually fail out of dual prime large fft within a half hour, and definitely within an hour (and in as little as 5 minutes).

    Core Temp reports between 40 and 45C idle (I turn my AC on and off frequently), and load between 54 and 61C ish. I don't know/care if Core Temp is off in any way, it at least appears to be consistent for me. And I understand that these temps shouldn't be what's affecting stability (because of the success with small fft prime). At 1.3500 Vcore the idle and load temps were still about the same.

    I've gone up to 1.3500 Vcore with no improvement in performance. I tried 1.4 northbridge, 1.35 (I think) FSB termination, and I've taken the ram up to 2.1V. By increasing the ram from 1.9 to 2.05 incrementally, I've noticed more stable performance overall. This RAM btw is Corsair XMS2 ddr2-800 with default timings of 5 5 5 12. I tried putting the timings down to 4 4 4 12 and that seemed fine too, so I dunno. It's running at 1:1, and so really it shouldn't be stressed in the least bit at these speeds. According to the new version of CPU-Z, the cpu Vcore is slightly less than what I set in the BIOS, which is confirmed by the bios screens below. I've decided I don't want to exceed 1.35V in any case (although again, that doesn't seem to be the issue).

    Increasing the FSB to 333 basically causes dual prime (both small and large fft) to fail pretty quickly. Large fft fails within seconds at that FSB.

    Any suggestions you have I will try, or any other tools you think I should use I will be more than happy to try. Screenies below:




    CPU: Intel i7 3770k. . . . . . . .Cooler: CoolerMaster Hyper 212 Plus
    Mobo: ASUS P8Z77-V Deluxe . . . . RAM: 4x4GiB GSkill Rampage 2133MHz 1.65V
    Video: Sapphire Radeon 7970 . . . Drives: Intel 520 SSDs
    Power: Seasonic Platinum 860W. . .Case: Rosewill Thor v2

    What is your RAM running at now?, when you are overclocking you are synchronising the MAX FSB and the MAX RAM speed. Then finally you use deviders to synchronise them.

    Also increase the voltage when you need to. You can also do with upping the Vcore a bit to 1.325.

    They are ddr800 ,and you have tightened them too soon , you tighten them in the end when you are happy with the overclock.

    What you do is use your ram deviders and before you start to overclock put them at about 80% to what they are rated at , later work yourself up to about 850mhz and you should be ok.

    850mhz should be what your modules will overclock to and give nice latencies ,after that you might not see overall gain by increasing the MHZ

    Actually the screens above are what they are running at currently. They're pretty much as loose as they can be. Running at DDR 632, with 5 5 5 12 6 42 timings.

    Your Vcore is low, that's likely your problem. Even 1.35 is within stock range.

    Hey, i cant seem to get my board to post at 400fsb, even if i try 400x6 it wont post, i tried raising the nb voltage and the fsb voltage, any ideas? its stable at 334x9 @ 1.3v 3ghz, but the fsb doesnt go much higher...........anyone with any ideas?.......my ram alsot passes memtest 2 times at ddr500 4-4-4-6 g.skill 2gb hz.....any ideas on how i can get higher fsb, doesnt seem to be my cpu.

    PCI-E clock to 100MHz
    PCI to 33MHz
    Spread spectrum - disabled
    More vcore and better cooling for cpu



    Life sometimes gets in the way of what we want to do.

    I have just picked up the P5B-D MB / E6300 and while there is a lot of views on this BIOS I have stuck with running 0507 BIOS, currently on all stock air cooling. I just found 0502 was not good - prob. with these particular modules.



    455x7 is currently working the best

    but have run 470x7...

    Key Settings I would look at would be the voltages... under Advance - all max'd out expect vCore which is around 1.525 iirc, prob a bit overkill but after changing these allowed for an improved OC - will take screen shots and post later if required....

    A lot of the time if Mem SPD is not Enabled (Auto) then would fail to post.... it even ran 400x7 2:3

    Need to get some better cooling and also get the head around Intel vs AMD OC'ing approach...
