    Hello all,
    I'm building a new rig and was hoping someone could give me some insight.
    I've got an FX-9370 water cooled and I'm debating the ASRock 990FX Extreme9 mobo.
    1000W PSU

    The ASRock website is a little vague on the memory QVL.
    I'd like to throw in 16GB (2x8) of AMD Radeon R9 2400 or 2133.
    Will I be able to OC it to 2400MHz stable with the 8 core CPU with your current BIOS?
    For now, later upgrade to (4x8GB) and partition a RamDisk.
    Any one have any experience with this memory/mobo combo?
    Or should I pay it safe with the 1866?
    I'll be doing a lot of 3D modeling/CAD and some motion renders. I would like to cut back on render hours.
    Temperatures should not be a problem.

    My other possible setup is the Gigabyte GA-990FXA-UD7/AMD 1866 RAM...

    Any thoughts?
    Thanks in advance!

    You might/should! get two sticks to 2400, but I'll bet my last dollar you won't get four sticks to 2400.

    Four sticks at 2133 should be doable with a bump of +0.05 to +0.10 to the CPU/NB(mem controller) voltage. I italicized "should" as every system is different, YMMV.

    If you shoot for the 2400 and it just doesn't want to play well you can always reap some benefit from it by lowering it Mhz wize and run with tighter timings, plus the CPU/NB voltage change.

    But four sticks at 1866 and a smallish bump to the CPU/NB is almost a guaranteed thing. AMD's memory controller is their low point and that's what all the above tries to clearly point out from my long AMD experiences.

    Thanks for the input. The Extreme9 Mobo arrived yesterday.
    I'm gonna go for AMD 2400 as it is actually cheaper than the 2133 at the moment.
    To start off with I'm only going to order 16GB (2x8GB)
    Then 16GB more so I'll be able to make the 16 or 24GB RamDisk.
    I've heard good things about AMD's software.

    Thanks again for your help

    You were correct. I went ahead with 32GB of the 2400 and tried a +.05 bump and couldn't even get my pc to boot to windows. Said I was missing a a .kernel

    I dropped the speed to 2133 and booted right up. My question now is Do you think I could get better timings out of the 2400 RAM running at 2133 speeds?
    If so any recommendations?
    Current Timings 10-11-11-29
    2133 @ 1.655v

    I should probably add that I'm currently OCing my FX-9370 ≈4.9 stable after a hell of a time. I can't get anything stable past that. Constant freezes, but that's for another topic.

    What'ya get?

    This?
    AMD Radeon R9 2400 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 2400 (PC3 19200) Desktop Memory Model R9316G2401U2K
    (edited as Newegg has since changed their PN's to reflect 2133Mhz sticks, not the 2400Mhz ones ending in 3007)

    Yes. That's them exactly. I'm sorry for not being specific.

    I've got 4 x 8GB (32GB Total) in right now.

    I get a .Kernel issue when I try to boot up with the XMP profile. (However, the XMP profile worked just fine when I had only 2 x 8GB in)
    Right now I have all four in down at 2133 with timings of 10-11-11-29 I believe.

    Do you think I can get those timings down? Or just leave it alone?
    I've never messed with the timings of RAM before, or tried to OC it.

    Post a couple of screengrabs from CPU-Z's Memory and SPD tabs if you would please.

    Also, the P/N R9316G2401U2K, that is what's printed on each of your four sticks, correct? That number exactly? It will most likely be displayed in the Memory screengrab you offer up. But just in case, I want to make sure you didn't receive/purchase/have some of the earlier Single Ranked mem that was also offered when these first came out. Most likely you don't have those but best to ask/check first. Stranger things have happened.

    Sorry it Took so long to get back.
    The part number R9316G2401U2K is the part number on both packages of RAM I received but CPU-z says something different. I don't know, maybe single sticks have a different part number than a dual channel kit?



    I believe I've got some problem with the memory. I'm getting an 04 Dr. Debug code and I cannot shut my computer down. I have to hold the power button down otherwise my PC keeps running after I shutdown through windows.

    Either I'm clicking on the wrong thing in the above post, or those pics got U/L'd improperly.

    But they're too small to make out on my end.
