    Can anyone share with the settings???

    My 4ghz FAILED after 36mins in Prime, Here are the settings:

    EIST: Disabled
    C1E: Disabled
    OC Stepping: Disabled
    Spread Spectrum: Disabled

    CPUBase Frequency: 200
    RAM: 1600 (8GB)
    CPU Ratio: 20 (multiplier)
    Mem Ratio: 4 (Lowest)
    QPI ratio: 16 (Lowest)

    VDroop: Low VDroop (I have only two options here Low or High)
    CPU V: 1.401v
    CPU VTT: 1.276v
    CPU PLL: 1.810 (Lowest)
    DRAM V: 1.651v
    PCH Voltage: 1.054 (Lowest)

    Screenshots:

    4Ghz (idle) always jumps with QPI, Bus Speed stays 200.4, Core V jumps to 1.426v sometimes.
    [​IMG]

    4Ghz (100% Load) 1.432 temp 48c
    [​IMG]

    4Ghz (100% load) 1.400v after 1024k passed in prime, Temp 51c MAX
    [​IMG]

    Please help! Or at leat put me in the right direction.

    Thanks in advance!

    My i5's at 4Ghz on the same board - try pushing up your VTT voltage and if you have the original bios disable load line calibration, I have my vcore at 1.282 at 4Ghz but my VTT and PCH voltages are higher than yours.

    My bios is 1.5 thats the problem, thanks for the input thats a start. Whats ur PCH and VTT? what about my other settings (QPI, Mem Ratio, VDroop?) are the ok? more or less.

    Load line calibration disabled
    Vcore:1.282 (actually 1.304 idle 1.352 load)
    VTT: 1.33 or so
    PCH: 1.17
    PLL: Auto (1.8)
    EIST: Enabled
    C1E: Enabled
    OC Stepping: Disabled
    Spread Spectrum: Enabled
    QPI Ratio: 18
    Mem Ratio: 4
    BClck: 199.5
    Core Multi: 20x

    Here it is running linpack - load temperatures are usually lower but I have a big heater pointed at me and the PC at the minute due to broken central heating and it must be about 30 degrees where I'm sitting :D And I've got tonnes of stuff open - usual score at 4Ghz is something like 56.5-57Gflops

    Ok thanks man! It seems i found the right spot. Currently on the fifth hour of Prime95 no errors at all. Wll come back with results a bit later.

    What are your settings at now? That's a lot of vCore for those clocks...

    I recently went crazy while trying to get my E7400/P45 system from 3.6 to 3.8 GHz. I set every voltage to stock and just concentrated on Vcore. It was easier to reach stability and it's rock solid stable at 3.8, meanwhile tweaking the other voltages left me dealing with errors and crashes. I now question the usefulness of touching the other voltages.

    If I drop either my PCH or VTT voltages to stock, I get crashes and BSOD, your choice :D

    Same settings! I can't figure out how to run for less then 1.4v with 4ghz, That will be cool if someone helps me.

    I have no problem with settings. but if you guys think less will be better, Then i'll try lowering it down, But i always get crash.


    Settings i touched! (P55-GD65 Bios 1.5)

    Try upping the PCH, other than that it may be that you've got a bit of a duff chip - might have to settle for 3.8-ish instead, I can get 4.3Ghz at 1.41v idle on mine..

    Ah, slang, a bad chip...

    Try playing about with the other voltages, but if you want to avoid the chip degrading over time it'd be best to get the vcore down a little, it's currently well into the "not recommended" section...

    Damn i cant get to 4ghz with low vcore, How about this one:

    I think temps are a bit high?

    Well that's not awful, that's roughly what my cooler gave me before I switched to higher CFM fans.

    Linpack will always make things a bit toasty, no real-world application will ever make it that hot again.

    Now try lowering some voltages and keep testing with 25 loops in linpack. The lower you can get the voltages, the cooler it will run.

    what he said ^^ I'm not used to Intel OCing, but its all the same general concept.

    Just thought I'd update this thread - I'm trying to take my Vcore as low as possible in order to have my fans running slower until I get my new fan controller installed (currently in the post).

    So I'm testing a new setup at 3.8Ghz - it can probably go lower as it's currently 1 hour linpack stable in OCCT with temperatures peaking in the high sixties with all my fans at 7V:

    Load line calibration disabled
    Vcore:1.257 (actually 1.272 idle 1.304 load)
    VTT: 1.295
    PCH: 1.149
    PLL: Auto (1.8)
    EIST: Enabled
    C1E: Enabled
    OC Stepping: Disabled
    Spread Spectrum: Enabled
    QPI Ratio: 18
    Mem Ratio: 4
    BClck: 190.5
    Core Multi: 20x

    I tried everything to lower my vcore down, Nothing helps. I'am currently on 3.8Ghz with vcore at 1.395 (in bios) running LinX (MAX problem size with 8gigs of ram) for over 5 hours no errors and Prime95 for over 10 hours no errors as well.

    My bios version is 1.5, maybe thats the problem (Bad bios) or bad chip!

    Your problem is your trying to overclock four dimm sticks. Your putting a large load on the IMC. You can either raise your vvt voltage (may also need more vdimm) or do like you did and lower your overclock.

    Do you have cpu skew? If you do give it 400 ps and see if that helps your 4ghz clock that you were showing earlier. Also turn off Spread Spectrum.

    Try pushing VTT to about 1.36-1.38, see if that helps.

    Myself, I'm currently running OCCT on these settings:
    Load line calibration disabled
    Vcore:1.232 (actually 1.248 idle 1.288 load)
    VTT: 1.272
    PCH: 1.141
    VDimm: 1.71
    PLL: Auto (1.8)
    EIST: Enabled
    C1E: Enabled
    OC Stepping: Disabled
    Spread Spectrum: Enabled
