    I just bought a new computer setup and I'd like to overclock the CPU a bit further. It's configured like this:

    Motherboard: ASROCK Z68 Extreme4 Gen3
    CPU: 1x Intel Core i5-2500K
    GPU: 2x ASUS EAH6970/2DI2S/2GD5 PCIE
    PSU: 1x Corsair 850W TX V2 (opted for 850w over 750w since it only cost me 15$ more)
    RAM: 1x CORSAIR 8192MB Vengeance DDR3 1600MHz CL9 KIT
    HDD: 2x Western Digital 500GB SATAIII 7200RPM 32MB WD5002AALX
    Case: 1x COOLERMASTER RC-932-KKN5
    DVD-ROM Read/write: 1x Samsung SH-S222AB
    CPU Cooler: 1x Cooler Master Hyper 212 Plus

    Now, I've followed all this guys settings http://www.youtube.com/watch?v=9e04-5hjk-I&feature=related except for having the LLC at 2 and the vcore at -0.035 offset mode (motherboard is a bit weird when it comes to the fixed mode, giving very fluctuating voltages). This gives the vcore a somewhat consistent value of 1,28 through stress testing, though it peaks at 1,31 sometimes. Seems like it's running stable at 4,5ghz at these settings as I've been running prime95 so far for 2 hours and had the intelburntest go through 50 runs. Temps are 70 +/- 4 degrees. Will keep stress testing it more of course. Seems like I can further decrease the offset voltage, and I guess this is only a positive thing. Maybe just keep downing the offset voltage by 0.005 and see when it freezes/crashes in stress testing?

    My question is simply if I should keep on pushing it and if so, with what settings?

    Nice OC . Thing is the only way you will know for sure is if you keep going . But 4.5GHz is great !

    Bump the multiplier up one and retest. If it fails, bump the voltage a little. Rinse and repeat, keep your temperatures in check.

    Btw, when looking in HWmonitor at cpu temps, should i also keep the Package variable under CPU under 80 degrees or should I just look at the core 0, 1, 2 and 3 and focusing on keeping them under 80?

    Core temps are usually a bit higher that package temp. Try to keep all values under 80 degrees.

    It bluescreens when going from -0.035 offset to -0.040 so I guess I'll keep it at -0.035 for 4,5ghz. That is about 1,31V at max value in hwmonitor. Temps are good as well, staying on about 73 degrees max.

    @exodus
    It's the other way around here. I get about 76 degrees at package temp while 73 at core.
