The IMC on the bulldozer die is supposed to support DDR3-2400. I think it's just a matter of finding the settings that will get me stable.

BD officially supports 1866 MHz. RAM frequency. Anything above that is the luck of the draw though BD does seem to OC RAM to 2000+ MHz. without too much effort. I suspect you may need some luck and the ideal settings to get to 2400 MHz. stress-stable.

I think I narrowed down the culprit to actually being my CPU. I guess the settings weren't as stable as I thought. I dialed back the ram and I am re-stress testing the CPU to confirm stability before I crank the RAM back up again.

better try memtest 86+ its will take around 30Mins to 45mins 2 runs of memtest is enough to say your RAM is stable and is a better test then the P95 smile.gif

Now that I made sure everything else was stable (10hr prime test) it seems to be flying through at DDR3-2400 without any issues. I just passed 3 hours and will be letting it run a full 8 to make sure. All with the same settings I was trying to get stable at earlier biggrin.gif

A nice side effect of retesting my system was that it looks like I have a lot more overclocking room for my processor than I thought I had before.

I had mine on that for a month, I built a new rig (R4E, 3930K, 1000w platinum) and 32 gb of this, I loaded the standard OC and just left it as I dont have time to tweak - but I did see that voltage which the BIOS/OS defaulted to was about 1.65. That being said, I am trying to get mine down, I have managed to get 2000 @ 9 9 9 9 24 2T 1.5v. But as another poster said there is real world noticeable difference between 1333 and 2133 - pretty much true unless you were using the RAM in ways that weren't typical from what I hear (ram disk/cache?) but I have not tried that in a real world situation. I have 32gb of this stuff and it runs Adobe CS6, along with everything else I have open at the same time (p2p, video, 40 tabs, chat, music editing etc etc) without any sweat. 1600 at 1.3v with loose timings or 2000 at tiggh timings, I can not tell the diff. But have at it if you want to push it. I think personally redhat's advice is fine, I have ran these babies 24-7 for a month or more at 1.65 - I think 1.5 would be ideal and even 1.475 from what I read on another forum. If you are tweaking, and have 8 dimms maybe play with 2 so you don't eff up the whole works. Good luck.

ive got it stable at 1600mhz at 7-8-8-24-33-1T at 1.575 V
and at 1672 mhz at (3:10 ) 8-8-8-24-33-1t at 1.5
i had ran these things to 2000mhz but i forgot the setting =/ also note for better stability i used Extream LLC for both my cpu and cpu/nb when i did that i also noticed that my motherboard (asus crosshair v 1402 bios) set my cpu/nb to 1.5 v for my cpu/nb( at 3000mhz) now ive done all testing oc to 4.ghz wich it just occured to me that, thats porbly why im losing stability hmmm im ganna try 2000 mhz without a oc of 4 ghz mabe somthing lower also if its any consolation wei score os now cpu 7.7 ram 7.8 graphics 7.8 graphics 7.8 harddrive 7.6 wei score is just for the lulz thumb.gif
