    oh, so the tRas is 20, not (26/28) according to the formula below :
    tRAS = tCL + tRCD + tRP (+/- 1)
    (26/28) = 9 + 9 + 9 (+/- 1)

    i'm using the default setting 7-7-7-30 (auto). and cpuz is showing that the memory is on 7-7-7-16. is this normal ? or should i set the timings manually ?

    Yeah now you get it. That is what it should be at 1066Mhz and the row cycle time should be 24T
    I beleive it's the bios it's misreading the 30T is acually 16T
    This is not the first time I have seen this.
    Try flashing the bios.

    tRP - Row Precharge Time 9
    tRAS - Row Active Time:+20+1
    tRC - Row Cycle Time =30


    tRC - Row Cycle Time:
    The minimum time interval between successive ACTIVE commands to the same bank is defined by tRC.
    tRC = tRAS + tRP +1 to halt errors

    x CAS# latency Auto 9T
    x RAS to CAS R/W Delay Auto 9T
    x Row Precharge Time Auto 9T
    x Minimum RAS Active Time Auto 20T

    x TwTr Command Delay Auto

    This is not the first time I have seen this.
    so, in this case, i must flash the bios to an earlier (F5/F6) ?
    in the current bios (F7b), can it work if i set the timings manually ? (1333Mhz, 1.65v, 9-9-9-20, tRC30)

    ps. there is a F7 (updated 20 nov) on the official site, i'll try flash into that first, then if fail try earlier versions...

    You can ALWAYS ignore what you see on the left in the BIOS when auto is used, for ALL Settings. This is often wrong and or not used, and should be simply ignored.

    No need to flash backwards because of that at all, and I actually advise you simply set this yourself manually anyhow

    i've set the timings to 7-7-7-20 trc 28, everything else is default (1066Mhz,ddr3 voltage 1.5v), everything seems to be working fine. cpuz says it's 7-7-7-20 too

    but, when i put the labelled setting (1333Mhz, 9-9-9-20, trc 30, ddr3 voltage 1.65v), the computer hangs on the white gigabyte screen (the screen where you press del to go to the bios screen). restarted the computer, still hangs at the white gigabyte screen

    i still can't get this machine running at 1333Mhz

    You may need more NB VID or Freq, but best to wait on Artdrivers to advise you on that as I am clueless with AMD

    i've tested each stick on all the slots, and i can conclude that slot 2 can't run at 1333 Mhz. so i put the sticks in slot 3 & slot 4, set the clock to 1333Mhz, timings to 9-9-9-20, trc 30, ddr voltage 1.65v, and voila ! it works

    i hope this helps others facing similair problems

    ps. i'll test some more, hopefuly this really is the final solution. wait for a while to confirm everything IS really ok. after that, i think the mods can pin this thread or sticky it

    Just for the record, I installed F7 bios and had several problems, like crashing at the Bios screen. But after turning off USB Mouse Support, it solved my problem, and the system is fully stable now.

    Also, my RAM only provided stable settings after setting Northbridge VID to +0.1V along with setting CPU-NB VID to +0.050V. If I run the memory at 1600Mhz, I have to set CPU-NB VID to +0.200V.

    This system was one of the hardest I had to make stable without overclocking. But I finally got it stable. But you have to increase the voltages in the Northbridge to run anything higher than 1066MHz. Seems like this current Phenom II stepping (C2) has an unstable memory controller. Probably next stepping will solve these issues.

    i never had a crash at the bios screen before, in all bios that i've installed (F5,F6,F7b,F7). could be a hardware problem... try isolating the problem, use another usb mouse, or use another ma790xt-ud4p mobo. you can try borrow the same type of mobo on the store you brought it or go to the distributor/dealer directly, gigabyte customer service helped me by testing my mobo free of charges... and later found out it was not the mobo, it was the processor that was defect (for my case).
    i'm still using a ps2 mouse, and i've used a usb optic mouse before (for gaming only), and never had the same problem you have. btw, i was using F7b, should be the same with F7, couse i don't see any fixes on the F7 change log.
    just curious, how did you found out you had to turn off the USB Mouse Support to solve it?

    i've just checked, the OCZ3P16004GK is only tested on Intel P35 and X38 Express chipsets. it doesn't says anything about it tested on an amd system, so you might have to set a few things to get it stable on your system.

    same here. never had an issue like this before. it's my first amd system, my last system was a pentium 4

    btw, have you tried using the white memory slots on the mobo (slot 3 and slot 4) ?

    I found on another forum a user that had the same problem as me with F7 Bios. So I'm quite sure it is a Bios problem. I found out the problem because this option comes disabled by default. And after updating the Bios, I came back to it to tweak a few settings. After enabling this option, my problems started. I believe I was lucky.

    i've just checked, the OCZ3P16004GK is only tested on Intel P35 and X38 Express chipsets. it doesn't says anything about it tested on an amd system, so you might have to set a few things to get it stable on your system.
    Yeah, you are right, my memory is not tested on this board, but there aren't so many OCZ memories tested in this board. I also heard that these Phenom II processors don't like high voltage RAMs. Too bad I learned this after I bought my memory.

    btw, have you tried using the white memory slots on the mobo (slot 3 and slot 4) ?
    I'm using the white slots, and they are much more stable than the blue ones. Now I'm happy with my system, after some time trying to make it stable it is finally good to use, and I'm for some time without any crash.
