Proper DDR3 1600 settings

What is the proper settings to get my Patriot Extreme Performance DDR3 1600 9-9-9-24 @ 1.8v to run properly (FireFox keeps crashing).

I do have it at 9-9-9-24 and 1.8v, default/auto is something like 7-7-7-20 1.6v and DDR3 1066 for this RAM

The board is a Gigabyte GA-MA790XT-UD4P

    What CPU are you using?

    AMD Athlon Phenom II X3 720 2.8GHz - AM3 CPU.

    Seems I might run it better at default until such time AMD can release a CPU that can handle DDR3 1600 RAM

    It can handle it: http://icrontic.com/news/amd-explains-phenom-ii-memory-downclocking

    I already know that, I just want to know if I can actually run DDR3 1600 at 1600, or let it run at the default 1066 (Auto)

    --EDIT--
    It seems if I adjust tRC to 33, though its currently running at 41
    Also, should I run it ganged or unganged?

    Ok, here's a snapshot of the memory settings. Seems the higher I set the settings, the worse the problems got.

    Also included is CPU-Z CPU and memory.

    I'd set everything in memory auto except for cas, trcd, trp, tras, and the voltage. Set those to the recommended settings for ddr3 1600 and just increase the FSB until your memory is at or near. If that is what you did and it still isnt stable try increasing the NB and Core voltages. Make sure your temps are decent before you fiddle w/ the Vcore though. I haven't messed w/ an AMD platform in a while so i dont know what to tell you to set specifically.

    Well, I am successfully running at DDR3 1333 by setting it at x6.66 and 1.8v (+.2v over default) and didn't touch any other setting (timings are auto).

    Its currently set at by auto settings (by looking at CPU-Z):
    9 Cas
    9 tRCD
    9 tRP
    25 tRAS
    34 tRC

    My guess is that if I set it to DDR-1600, I should set it to 11-11-11-30-41 and +.25v over default to get it to run smoothly.

    you shouldn't have to loosen timings and set higher voltages to get memory to run at it's rated speed, if you do its bad and i would return it. This is also a question you may want to bring to the memory companies support forum, if you haven't already.

    Long story short: The Phenom II unofficially supports DDR3-1600 if you adjust the voltage upwards slightly. Straight from AMD's mouth.

    If you're not receiving that performance, you need to try other memory.

    Yeah, I should try the Muskin RAM (http://www.newegg.com/Product/Product.aspx?Item=N82E16820146777) or the Wintec (http://www.newegg.com/Product/Product.aspx?Item=N82E16820161283) which was the first RAM I considered buying, For some reason, after 5 hours, it decides to cause data corruption in my Microsoft Money file and then freeze Windows.

    Can a AM3 board handle running DDR2 800 modules that I have while I RMA this RAM?

    Well, so far so good. Got it running at DDR3 1600 @ 9-9-9-24-42-2T and 1.9v with no problems.

    Well, I got a IRQ NOT LESS THAN blue screen error, though I got the IRQ errors before changing hardware when I installed the Creative Labs beta drivers for the SB Audigy SE for Windows 7.

    It probably doesn't help that I didn't reinstall Windows 7 when changing out the motherboard/RAM/CPU.

    And here's something odd about the instability from testing: I can't delete anything.

    Ok, I ran memtest86+ 2.11 while at DDR3 1600 and got about 10240 errors. Ran it again at DDR3 1066 and got no errors.

    Also, unless I'm missing something, I thought all the AM3 motherboards were dual channel DDR3, but Gigabyte's qualified vendor list for this board are mostly tri-channel RAM.

    I'm paying attention, in fact I was going to suggest Patriot's forums. Looks like you beat me to it though.
    Unfortunately the DDR3 settings appear to be different between the Intel/AMD setups.

    I've got 1 set of Kingston Hyper-X ram, I got the specs from their site. The voltage for 1600 was 1.7-1.9. 1.76v was the "sweet" spot. 1.9 was a no boot. 1.8v was unstable. 1.7 was unstable.

    This may or may not apply, just pointing out some ram can be real picky about the voltages.

    Something else just clicked. One set of ram I've got will default to 1T instead of 2T when installed. Right now I don't remember which ram or even what board it was on.

    I've decided to buy this RAM Friday since its on the QVL for the motherboard: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231193

    Dan,

    Check out Tony's results on the MSI board. High memory speed is not where it is at.. get that NB speed up.

    How is this going to get my RAM to run at DDR3 1600?

    It wasn't aimed at getting your ram running 1600.

    I was showing you that performance is better or = to DDR3-1600 at DDR3-1333, tighter timings, 1T, higher NB speed and it is way easier to get stable.

    Tony did that stuff in about 15 min and it runs everything he throws at it.

    Just making suggestions.. running things that take 6 hours of tweaking and testing isn't my kind of fun (1600MHz on the ram is not easy and straight forward) just trying to share some info :).

    That looks more complicated trying to figure out what setting is best, compared to just setting your RAM and forgetting.

    Right and that has been real successful so far ;)

    I was just giving options :)

    This thread at this forum: http://www.xtremesystems.org/forums/showthread.php?t=217697 A few posters suggest moving the RAM to the white slots since apparently they run better. I am going to try and do that.

    Not many of use have a lot of experience with this platform, and ryder has more exprience with memory than most of us so if you dont want to follow his advice, good luck. :thumbup

    I switched to the white slots, ran memtest86+ and got 6 errors on test 5 on the first pass, second pass there were no errors for test 5

    --EDIT--
    It appears to be running quite nicely in this config.
    Settings are:
    9-9-9-24
    2T Command Timing
    6T TwTr
    110ns Trfc0
    12T Write Recovery
    3T Precharge Time
    41T Row Cycle Time
    7T RAS to RAS delay
    1.8v DDR3 Voltage Control
