    Just a heads up I'm brand new to messing with memory timings so thanks in advance.

    Mobo: asus m4a79t delux
    Cpu: amd phenom II x2 550
    Memory: corsair cmx4gx3m2a1600c9

    When first installed it read at 1333. I've changed it in bios to run at 1600. Next though I ran cpuz to check timings:

    Cl: 11
    T
    TRCD: 11
    TRP: 11
    TRAS: 29
    TRC: 41
    Cr: 1T
    Dram frequency: 802.7
    Fsb: dram: 1:4

    Nb frequency: 2006.7


    Has anyone gotten this memory to run with better numbers on this board? What values can I change in bios safely with modest cooling? Let me know if you need more info. Thanks again.

    You should really know your memory's specs. :ohwell:

    At 1600 those modules support latencies of 9-9-9-24 @ 1.65 volts.

    So make these:

    Cl: 11
    TRCD: 11
    TRP: 11
    TRAS: 29

    Into this:

    Cl: 9
    TRCD: 9
    TRP: 9
    TRAS: 24

    And make sure the voltage is proper.

    Thank you for such a quick response. I knew it was 9-9-9-24 just wasn't sure I could set them safely on this board lol. Should I do anything with trc? Should I keep it 1T or 2T? And what voltage (estimate) do I need? I know as I increase voltage in bios it turs yellow then red as I increase it. Think starts turning yellow at 1.6

    Thanks again for all the help.

    Well the RAM requires 1.65 volts for these settings, but it could probably hang with just 1.6 if you're worried or want to be conservative.

    You could try a TRC of 38 for starters. 1T should be fine.

    glad director got ya set. if you just found them youd be right in sticking around. hell iv been addicted for 5 years. ya gotta watch this place at first its casual. then you visit it every few hours. then you make it your home page. then all of a sudden you blowing thousands of dollers on things complete strangers tell you to get. then all of a sudden your having fun. Its like crack. At this point i dont think i can stop even if i wanted too it would probably just kill me.

    Welcome to TPU bro, i'm sure you will enjoy it here, i do and people here are VERY friendly and helpfull afaik:D

    and you can set the voltage to 1.65 with no worries, AMD boards/CPU's is not as bad as Intel ix xxx cpu's when it comes to the voltage:D

    i have my XMS3's 1333mhz running at 1444 mhz and 8-7-8-24 atm, and they are rated for 1333-9-9-9-24, and i'm quite sure your's will do something similar



    +1 on that haha:roll:
