  1. yeah why not its ddr3 1600 and your mobo should be able to take 1600, since u have 2gb x 4(8gb) just dull channel them in all the blue slots or just 2 in the blue and 2 in the white.
  2. It's not listed on the verified memory support list but similar RAM from Kingston it will work OK.
  3. I have 2x2Gb Kingston Xyper X 1600 (KHX1600C9D3/2G) in my motherboard,
    when i put anather 2x2Gb, my PC is dead.
    What can i do? PLZ HELP!

    I had a similar problem. Seems the GA-P55-UD6 chokes with more than two memory modules. All was fine with 2x2Gb sticks of Corsair TR3X6G1600C8G running at rated voltage, speed, and timings: 1.65v, 1600 MHz, 8-8-8-24, but when I added 2 more sticks (four total) all hell broke loose. After dumbing down the RAM settings in the BIOS, I have a mostly stable system. Here's what I did:

    1) Enter the BIOS and select MB intelligent Tweaker(M.I.T), press Enter.

    2) Select Advanced Memory Setting, press Enter

    3) Make the following settings:

    Advanced Memory Profile (X.M.P.) [Profile1]

    System Memory Multiplier (SPD) [10.0] (this reduces the memory frequency from 1600 to 1333 MHz)

    Performance Enhance [Standard]

    DRAM Timing Selectable (SPD) [Quick]

    4) Save settings and exit

    Don't use the Fail-Safe default settings unless your RAM only requires 1.5v. Updating the BIOS from F3 to F6 made no difference. Gigabyte has since released BIOS update F7 (2010/01/28) for the GA-P55-UD6 which is supposed to add "Enhanced memory compatibility." I've not tried it.

    Incidentally, this is my first, and last, Gigabyte motherboard. Internet forums are littered with similar woes. I don't feel that the GA-P55-UD6 should have been unleashed on the general public without first addressing the memory issue. I also think it's misleading to advertise six memory slots because of the weird mix of both single and double-sided RAM modules required to make use all six slots.
  5. I too have a very similair problem with this mobo (F9 bios version) and Kingston Hyper X C7 1333 8gb kit (4x 2gb) memory

    I have BSODs and memory errors when running 4x2gb at XMP settings (7-7-7-20), but when running with 2 modules there are no issues at all. Reducing the memory timings manually to 9-9-9-24 @1.5 (1333mhz) solved the problem but affects performance ofcourse. (No overclocking)

    Side note Gigabyte Easy Tune 6 shows significantly different timings in the timings table for my 4 modules, one of the modules even has a different manufacturer (GENNUM). Should I return these modules? I presume this is not normal right?


  6. Sorry for picking up this old thread again but I found the solution!

    The default BCLK of the Gigabyte GA-P55-UD6 is 136mhz instead of the conventional 133mhz.
    Therefore, after multiplication with the memory clock multiplier, the memory is clocked at a slightly higher speed than what the timings are rated for. (My 1333 mhz memory is clocked at apprx. 1360 with the 136 BCLK instead of 1330mhz, its 7-7-7-20 timings are rated at 1333mhz)

    At this slightly higher speed your memory controller may not be able to handle the strain of maintiaining the rated memory timings for 4 modules (this was not an issue with 2 modules). Fixing the BCLK to 133 fixes the issue and allows your memory to run at its true speed and rated timings (at least it did for me :)). You lose the 2.2% BCLK advantage though.

    Alternatively you can always slighltly increase your timings.
