    Default Haswell Overclocking Guides / Results

    Here is a guide that I followed,
    Now, Iíll share a secret imparted by the folks at ASUS who gave several reviewers some tips on overclocking the retail stepping Haswell chips: Set Vcore to 1.20 V. Set all cores to 46x (which would be a 4.6 GHz overclock), save & reboot. If the system boots past the UEFI and either begins to load or, ideally, makes it into the OS and is stable, you have a 50th percentile or greater chip on the Haswell overclocking-ability bell curve. If it wonít at least boot there and make it into the UEFI, you probably have less than a 50th percentile chip. You can expect chips in the lower 50th percentile to top out in the 4.4-4.5 GHz range at 1.25 V.

    If your chip will boot at 4.6 GHz and 1.25 V, thatís very good. It means you have at least an average chip. If it will boot at 4.6 GHz and is stable there, then you may have an above average chip. The best chips will be able to do 4.8 GHz stable at 1.25 V. Our sample did 4.8 GHz, but at 1.3 V and on a custom water loop. Using 1.3 V will likely put a chip out of the air cooling / AIO water cooling thermal envelope. Temperatures in all of these scenarios, from the dog 4.3 GHz chips up to the good 4.8 GHz chips, will always be in the ~90įC range. Thatís just the nature of Haswell. With the VRM on-die, think of Haswell as Ivy Bridge plus 10į C.

    Regrettably, according to overclocking legend Andre Yang, there is no way to bin Haswell for extreme overclocking purposes on ambient cooling. You couldnít do it with Ivy Bridge either. That ship sailed when Sandy Bridge, well, went under the bridge and continued down the river. If youíre binning for extreme purposes (of which the esteemed Mr. Yang has binned over 500 chips as of late April), you simply have to take them cold. However, for most peopleís uses, the method above to bin on air is tried and true through the hundred plus they have binned at ASUS headquarters.

    So, to sum up,

    First check to see whether you have a chip on the upper end or the lower end of the Haswell bell curve.
    There will be a large variation as you can see, from the 4.3 GHz dog up to the ideal 4.8 GHz chip, both at the same voltage and temperature.
    Once youíve checked on your chip, you have a general goal and can then set 1.25 V Ė manually, so it doesnít overshoot like it would on Progressive voltage.
    After setting 1.25 V, then raise the multiplier.

    The Gigabyte Z87/Haswell Overclocking(OC) Guide

    It got me 4.5ghz at 1.325v llc Extreme. Cpuz and RealmTemp have problem reading base clock. I have to update to f5i and see if that helps but some times realtemp gets it correct.



    Edit - Update new cpu.

    Since that cpu sucked I went to MicroCenter and picked up a new cpu.



    Edit 2 - LLC set to extreme

    try ones in my sig,maybe do 9-11-11-20 or 19-1t trfc 88 1.55v dram

    or 9-10-10-20-1t same voltage

    you might even run above 2200mhz,thats my limit on z77/Samsung green

    Not sure if this bios problem or no problem or cpuz/realtemp probelm. Cpuz and realtemp never read 100 bclk a load. Some times realtemp will but at load some times it will jump up to 104 while cpu will read 3-4 mhz lower then 100. If I set bclk to 102 same problem.

    Also while uncore is set to 45 GTL 2.0 shows 38. If the uncore speed is supposed to be the NB frequency in cpuz then that never goes past 3800, well 3728 since bclk not 100 when it should be. I have tried cpuz 1.62.2 - 1.64.3. Bios test f3 stock, f5h, f5i

    Seems like a good piece of CPU (average). But do not use Real Temp, it shows bad temperature. Use core temp.

    Guess I got lucky :D

    CPU-Z Validator 3.1

    4.7 @ 1.28, also it will scale right back to 800mhz using 0.77v when i'm just browsing which is nice on the electric bill (8w instead of 100w at full load).

    Running a custom 360 rad with EK supremacy block and temps occasionally hit 80 when using the AIDA stability test.

    Also hugely impressed with the GeIL Black Dragon DDR31600 as I got that to hit 2000mhz @ 1.65 but want to get some cooling on it before I run it at those speeds regularly as it's just bare PCB and air circulation isn't great in my chassis with 6 HDDs.

    Ok so I figured out my bclk issue with realtemp and cpuz. It was either corrupted windows or windows 8/driver issue with new chipset/cpu. I am on a fresh install of win7x64 and both cpuz and realtemp read correct bclk.

    have you tried pushing the Samsung ram past 2400mhz? the limit was 2300mhz on ib for me,would be interesting to see on haswell,1.65v dram is safe to use on that ram
