    Default GA-MA790XT-UD4P @ 1600mhz

    Hi,

    I was wondering if any1 has managed to get there memory working at the rated 1600mhz. Im not sure if there is an issue with OCZ memory and this motherboard but after searching many forum posts I have still not found any1 that has managed to post stable at 1600mhz.

    Im not sure if this is an issue with the memory or the motherboard but the memory seems to run fine at the below timings (6-6-6-24 1t @1333mhz).

    Im hoping that this maybe just a compatiabilty issue and maybe addressed with a bios update but was wondering if any1 had any idea's?

    Many thanks for reading :)

    Hi,
    I've not got OCZ Ram, but I do have Corsair RAM (C9DHX) running in my rig at 1600Mhz.
    I've also put OCZ RAM into a friends PC which was this motherboard and the Phenom II 550 BE - that also ran at 1600Mhz. I think it was the same ram (the OCZ Animal Range for AM3).

    Are you running on the latest BIOS version.

    what kind of Mobo do you have? i have a TW3X4G1600C9DHX and i cannot get my computer to run stable @ 1600mhz+ either. do you mind posting your settings?

    Hi,

    Here's my settings for a Phenom II 955BE running on the GA-MA790XT-UD4P (The Ram is running tight timings at 1600Mhz, and the NB/HT is at 2600Mhz. No O/C on the CPU) :

    MB Intellient Tweaker (M.I.T.)
    CPU Clock Ratio = Auto (3200Mhz)
    CPU Northbridge Freq = x13 (2600Mhz)
    CPU Host Clock Control = Auto
    CPU Frequency (Mhz) = 200
    PCIE Clock (Mhz) = 100
    HT Link Width = Auto
    HT Link Frequency = x13 (2600Mhz)
    Set Memory Clock = Manual
    Memory Clock = x8.00 (1600Mhz)
    System Voltage Control = Manual
    DDR3 Voltage Control = +0.200V (1.800V)
    NorthBridge Volt Control = Normal
    SouthBridge Volt Control = Normal
    CPU NB VID Control = +0.200V
    CPU Voltage Control = Normal
    Normal CPU Vcore = 1.3500V

    DRAM Configuration
    CPU Host Control Clock = Auto
    CPU Frequency (Mhz) = 200
    Set Memory Clock = Manual
    Memory Clock = x8.00 (1600Mhz)
    DCTs Mode = Unganged
    DCT (Channel) Interface = Enabled
    DDR3 Timing Items = Manual
    CAS# latency = 7T
    RAS to CAS R/W Delay = 7T
    Row Precharge Time = 7T
    Minimum RAS Active Time = 20T
    1T/2T Command Timing = 1T
    TxTr Command Delay = 4T
    Trfc0 for DIMM1 = 90ns
    Trfc2 for DIMM2 = 110ns
    Trfc1 for DIMM3 = 90ns
    Trfc3 for DIMM4 = 110ns
    Write Recovery Time = 8T
    Precharge Time = 4T
    Row Cycle Time = 27T
    RAS to RAS Delay = 4T

    The ram is installed and running stable in the 2 slots furthest from the CPU.
    Judderman - Just noticed you're running the latest BIOS which I am too.

    Hi Gunnar :)

    Thanks for posting your timings, I am now running the bios F4I to see if that will allow me to run stable at 1600mhz, this bios version was only released very recently. Im not sure if it makes any difference but I am currently running the RAM in the slots nearest the cpu so mite also have to try seating the RAM into the other slots.

    Many thanks for your time thou and I will do some testing ASAP and post back the results,

    Many thanks :)

    I'm also having the same problem with the same Ram but with the Gigabyte MA790FXT-UD5P, I'll try the settings as above & report back also.

    I've got 2 sticks of some older OCZ PC3-1333C7 Platinums 1.8v that work fine with the board at spec.

    Hi Folks,

    No joy for me still at 1600mhz with the new bios (F4I), back to the old timmings of 1333mhz @ 6-6-6-20 1t.

    Fingers crossed the next bios will support OCZ memory, I find it incredible that a company like Gigabyte only has 1 set of OCZ ram on its memory compatiability listing.

    Kind regards,
