    Slight overclock wanted

    Hi all. I run a slight oc on my older rig and want to tweak my "newer" rig. I was running

    stock for the last year. I could play COD, Crysis, Farcry2 well enough so I didn't do any

    oc. Ran cpu-z and discovered speedstep, which I don't like and have been unable to disable.

    But people say don't worry about, you get the performance when you need it. Anyway I

    installed Easytune and allowed it to oc me to 9x400=3.6 but after an hour of gaming my video

    went funky so I went back to default, I think. I'm running 9x333 now. Never touched mem or

    gpu or voltages, but Easytune probably did. So I'd like to do slight oc. When I say slight

    I mean as much as I can get without doing anything with my current cooling setup. With that

    in mind, I'm all ears.
    1) i5-2500K cpu, Gigabyte GA-Z68A-D3-B3, MSI GTX 970 GDDR5, 8G Gskill DDR3-1600 PC3-12800, Acer 23", H233H, Win7 64 bit, Corsair 650TX, Xigmatek cooler, Cooler Master CM690

    check the bios for the stock vcore and compare it to what ez tune gives it at oc. run this, watch temps and see if it busts.

    as for the speed step control in the bios, check in advanced features. that's where it is in my amd gigabyte board.

    On that Gigabyte EP45-UD3P (and most other Gigabyte Intel boards) SpeedStep is found under the Advanced Bios Features. You need to disable two entries, CPU EIST (Enhanced Intel SpeedStep Technology) Function and CPU Enhanced Halt (C1E). This information is found on pages 51 and 52 of your owners manual.

    AMD systems do not have SpeedStep. That is something only Intel systems have. AMD uses the similar PowerNow or Cool'n Quiet depending on the age of the system.

    And Easy Tune is a joke. It is too unstable to use for more than simple testing to get some idea as to the amount of Overclock might be possible. To properly overclock that board you need to go into the M.I.T section of the bios and do it manually. Fortunately, that model has one of the most exhaustive amounts of bios settings available when it comes to overclocking, but it is also it's weakness as anyone unfamiliar with overclocking will more than likely get lost in the myriad of settings and options. That bios makes a lot of Oskar Wu's DFI bios look simple.

    i know, i did a translation on the fly.

    glad you were able to add to what he needed to look for.

    Re: Slight overclock wanted

    I have been using Gigabyte Intel based boards for the past several years and have gotten fairly familiar with them. I won one of these boards earlier this year. I figured you did something like that when you posted.

    Here's an example of a successful OC on another persons E8400 on that motherboard. Please note that this person is using PC2-6400 ram instead of your PC2-8000 ram so you'll need to make some adjustments to your ram timings to reflect what yours uses.


    CPU = E8400 E0
    Motherboard = EP45-UD3P (Rev. 1.6)
    BIOS Version = FD
    Ram = mushkin kit # 996580 (2 x 2 GB of DDR2 800)


    MB Intelligent Tweaker(M.I.T.)
    Robust Graphics Booster .............: Auto

    Advanced Clock Control
    CPU Clock Drive......................: 800mV
    PCI Express Clock Drive..............: 900mV
    CPU Clock Skew.......................: 0ps
    MCH Clock Skew.......................: 0ps


    DRAM Performance Control

    Extreme Memory Profile (X.M.P.)......: Disabled
    (G)MCH Frequency Latch...............: Auto
    System Memory Multiplier ............: 2.00D

    Channel B

    Motherboard Voltage Control

    CPU
    Load Line Calibration (LLC) .........: Disabled
    CPU Vcore............................: 1.33125
    CPU Termination.....1.200V*..........: 1.240
    CPU PLL.............1.500V*..........: 1.590

    ICH I/O.............1.500V...........: 1.500
    ICH Core............1.100V...........: 1.100

    DRAM
    DRAM Voltage .........1.800V.........: 2.060 (2.05V in Hardware Monitor)
    DRAM Termination .....0.900V.........: Auto
    Channel A Reference ..0.900V.........: Auto
    Channel B Reference ..0.900V.........: Auto


    (Important: For the MCH Reference, set the CPU Termination to 1.200V first, and then set the MCH Reference to 0.720v. Then raise the CPU Termination back up to 1.240V so that this scales properly to 0.740.)


    I don't know how well these settings will work for you, but give them a try anyway just to see what happens.
