  • F3-14900CL9D-8GBSR + Gigabyte GA-790XT-USB3 + AMD Phenom II x4 955BE

    Specs:
    CPU: AMD Phenom II x4 955 Black Edition
    Memory: G.SKILL F3-14900CL9D-8GBSR (4GBx2 Kit)
    Motherboard: Gigabyte GA-790XT-USB Rev. 1
    BIOS Version: F5a
    Operating System: Microsoft Windows 7 Professional x64

    What I am looking for:
    I am looking to get my timings closer to the advertised values or better and/or include the clock up to 1866MHz that is advertised.

    Problem:
    I can not get this to run any higher than 1600MHz or lower timings than these default 11-11-11-28-1T.

    If I change the timing from auto to manual it doesn't make it past POST. There must be a timing that isn't right (there is a ton of extra options when you set timings to manual, SEE PICTURE BELOW). I am ok with over clocking it if it needs to happen. I am not very experienced in overclocking, but I am willing to take someone's advise.

    Might look here for help to 1600

    http://www.gskill.us/forum/showthread.php?t=7688

    I've seen a few 955s that can carry 1600 (generally at CL10/11), but generally speaking the 965 Rev C3 was the first in the Phenom line that could carry 1600. The 955 is actually a 1066 rated CPU, so it's expected to carry UP to 1333 at 1 stick per channel. Extra CPU/NB, DRAM and CPU voltage can help


    Pls offer comments on support I provide, HERE, in order to help me do a better job here:

      Let us know how you do with the guide. Based on your photos, there are quite a bit of settings that need to be changed.

      Thank you

        I had a very similar setup to yours, except I had the 790fxt, not the fxta, and 16 GB DDR3 1600 MHz, not 8 GB DDR3 1866.

        I was able to get my 16 GB ripjaws kit stable at 1600 MHz, but it took a mountain of cpu/nb voltage; I sold it a month or so ago, but I recall adding up to .3V to get it stable. My ram timings were 9-9-9-24, and I ran the ram at 1.6V. I had the cpu clocked at 3.8 GHz, using only the multiplier, and it required about 1.525V to be rock solid.

        I had a Noctua NH-D14, and at those settings, it was borderline 60C under load.
