OCing 1333 to 1600 on asus m4a89gtd pro/usb3

Hello friends,
This is my first build,

1. AMD Phenom ii X6 1090t (black edition)
2. Asus M4A89GTD PRO/USB3 Motherboard
3. Sapphire Radeon HD5870
4. Gskill F3-12800CL8D-4GBRM x 2 (total 8 gb)

As u all know that by default this mobo runs the ram at 1333Mhz.
Now, to utilize the rams full potential....

How to overclock it to 1600 Mhz ??????

m worried cause its my first pc build and i dot wanna burn anything :(

it would be better if u show me an illustration or video...

thanx in advance.

    Why bother? You will get maybe a 3% boost......leave it as it is. You want to OC, OC the CPU and the GPU.
  2. I am currently running the exact same motherboard and RAM. You can search the GSKILL forums for the ram and/or motherboard and find semi-decent information (I have posted a few times).

    1. AMD Phenom II X4 965 125W 3.4GHz
    2. Asus M4A89GTD PRO/USB3
    3. Gigabyte GV-R485MC-1GI
    4. GSKILL F3-12800CL8D-4GBRM x 1kit

    Make the following changes under Ai Tweaker menu in the BIOS:
    Ai Overclock Tuner - change to Manual
    DRAM Frequency - change to 1600 MHz
    DRAM Timing Configuration - change first 4 options and last option as follows
    CAS# Latency - change to 8 CLK
    RAS# to CAS# Delay - change to 8 CLK
    RAS# PRE Time - change to 8 CLK
    RAS# ACT Time - change to 24 CLK
    Command Rate - change to 1T
    CPU & NB Voltage Mode - change to Manual
    CPU/NB Voltage - manually key in 1.2000
    DRAM Voltage - manually key in 1.6000

    I then went to the Tools menu and changed the O.C. Profile Name to Stock and saved it as Profile 1. These settings have given me very stable operation and were confirmed by GSKILL Administrators.

    In fact, these settings were so stable, a simple manual key in of 20.0 for the CPU Ratio gave me a no-hassle, stable 4.0 GHz overclock (which I saved as 4GHz for O.C. Profile 2). Here is my CPU-Z validation link:
  3. I typed this out while looking at the BIOS options and thought that anyone willing to build their own PC should be able to figure it out. But if you really need a screenshot or video, I can make one for you relatively easy. Just PM me.
  4. if i wanted to OC jus my cpu, can i just leave the ram alone?
  5. I found an answer to this same question at the ASUS support page for this board. It involved changing the AI OC Tuner to D.O.C.P (what the heck does that stand for?) which changes the memory to X.M.P mode and then you can select a DRAM OC profile from the list (I think this is read from the memory itself, "Profile #1....Profile #2...etc).
  6. Stuff gets complicated in regard to memory and cpu overclocking. Many OC solutions out there involve cranking up the Front-Side-Bus speed but this also forces the memory to run faster. My DDR3 Patriot sticks are meant to run at 1333 MHz which is actually 667 MHz. If your CPU has an unlocked multiplier, you can leave the FSB at 200 MHz and just fiddle with vCore voltage and multipliers near as I can tell. I did find that my 3Dmark11 score went up a few hundred points by getting my memory from 533 MHz to the 667 settings. If you have 1600 memory, you can probably get an even better score.
