I have a Crosshair Formula V with an FX 8350 Processor and (2x4GB) G.SKILL Ripjaws X DDR3 2133 (9-11-9-28 1.65V) and the system will freeze randomly including in Memtest-86 4.0a (boot from CD-ISO). I previously had a Phenom II 1100T (running the RAM at 1600) instead of the FX-8350 and it worked perfectly. I thought the CPU was faulty and RMA'ed it but the replacement is doing the exact same thing.

I have tried it at 1333 and at 1600 but it still randomly freezes. I can get each stick to run just fine for 20+ passes individually but not when they are both in. To clarify I am not trying to get the 2133 speed I just want both sticks to run stable in my system at either 1600 or 1333. I also realize that the ram is not on the qualified list but I had it working just fine with the Phenom II 1100T Processor.

As a side note I have tested the CPU, RAM, PSU, Graphics card, SDD in another computer they all worked fine. I also tried a fresh install of windows 7 Ultimate (64bit). All drivers are up to date and temps are also good, with nothing above 50°C. I also was recommended to raise the CPU/NB Voltage to 1.32 then to 1.4 from the guys at gskill but that didn't help either

Here is my current settings and any help would be greatly appreciated
