  • Which RAM to buy for AM3+ MSI motherboard ?

    Hi, as posted here: http://www.gskill.us/forum/forum/pro...-a-990fxa-gd80 I'm looking for the best RAM for a MSI 990FXA-GD80 MB. Can you help me realize why 2133 ones are not listed on "G.Skill RAM Configurator" ?

    This is my current build:
    cpu: FX-8150
    mb: MSI 990FXA-GD80 (MS-7640) v2.2 it has a v13 BIOS 01/28/2013
    ram: 12GB (3x4GB) 1866mhz Corsair Vengeance
    gpu: R9 270X 2GB
    psu: 850w Thermaltake
    os: win 8.1

    Willing to upgrade RAM, CPU, GPU. I expect running a stable & reliable high quality rig intended for office use rather than gaming. Prefer to avoid troubles messing with OC functions if possible.
    Given the fact that MSI is advertising DDR3 2133 support for their 990FXA-GD80 MB however some folks reported some issues on this forum back in 2011 having to manually set basic timings and DRAM voltage with such high frequencies memories.

    Today last BIOS available at MSI support is v13.6 (2015-06-15) perhaps things have changed now?


    Thanks in advance !

    DDR3-2133 is too stressful so it is not listed. Will be very difficult for the user to reach and stabilize.

    2133 is more possible with 2 modules, but with full slots most likely it will be too much load.

      Thanks, I already bought 1x4GB 1866 module but didn't installed yet.
      I'm considering selling them all in order to replace it with 32GB instead. Which GSkill set would you recommend then ?

          What if I buy 4x8GB = 32GB @ 2133 w/ FX-8370 w/ custom bios + lowering ram timings in order to stabilize them ?

          btw, both Ripjaws & Trident X Series modules you recommended are 1.6v. MSI says the mobo I'm using supports v1.5 so I guess G.SKILL Ares Series 32GB (4 x 8GB) 240-Pin DDR3 SDRAM 2133 (PC3 17000) Model F3-2133C11Q-32GAR is the only valid setup. Other brands barely manufacture 2133 modules.

            Base is DRAM Voltage 1.50V, the motherboard can support higher without a problem.

            As long as you use a single 4 x 8GB kit, the RAM is guaranteed to work at the specs together so then it just depends on how well you can set it up for your system to maximize performance with stability.
