  1. or this one?

    SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-4GBRL
  2. There are a large number of G.Skills on the memory compatibilty list, but be sure to read all the 'notes', many are limited to two DIMMs and subject to 'down-clocking'...

    Some of the difficulties are outlined in Revision Guide for AMDFamily10h Processors:

    263 Incompatibility With Some DIMMs Due to DQS Duty Cycle Distortion [p46]
    293 Memory Instability After PWROK Assertion [p54]
    300 Hardware Memory Clear Is Not Supported After Software DRAM Initialization [p58]
    355 DRAM Read Errors May Occur at Memory Speeds Higher than DDR2-800 [p84]
    370 DRAM Read Errors May Occur at DDR2-800 Memory Speeds With Higher Read DQS Delays [p89]
    417 Processor May Violate Tstab for Registered DDR3-1333 DIMMs [p119] (doesn't apply to many - desktops seldom use registered DIMMs...)
  3. what does that mean tho? i am new at building rigs.. so i dont know they can be used.. =(
  4. Basically, if something's on the memory compatibilty list, it has at least worked for someone at GIGABYTE, and their support should be able to tell you how to make it work, should you run into difficulties - I can help, but am of 'limited utility', as I just 'don't do' AMDs - I've got my hands full, just keeping up with Intel's difficulties!

  5. ok bases on the chart.. this one seems to be good

    G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Dual Channel Kit Desktop Memory Model F3-10666CL8D-4GBHK

    can someone double check, if its good, then im gonna go ahead and order
  6. I'd go ahead - it is listed in GIGABYTE's memory list as compatible:

    and the specs page of the G.Skill page mentions compatibility with your chipset specifically:
  7. i would buy this

    btw lots of ppl are running it on AMD mobos
  8. RipJaws F3-10666CL7D-4GBRH,
    and F3-10666CL8D-4GBRM are listed as compatible with the chipset in G.Skill's documentation;
    F3-12800CL7D-4GBRM is not... It lists:

    This is certainly not to say it will not work; but it's not 'supported' - which generally transtates to: "you is on your own!" See Part III - "Evaluation and selection", in the The difference between "Supported Speed", and "Supported Speed"! and The 'Memory Support List', and how to use it: sections...
