Hello everyone,
So I recently rebuilt my PC with all new parts, and I'm having trouble getting my RAM to work as advertised. Here are the need-to-know specs so you have an idea where I am at.
Mobo: ASRock 990FX Extreme9, latest 1.5 official BIOS
CPU: AMD FX-8350
RAM: Corsair Vengeance Pro 2133MHz 9-11-11-31 1.65v (16GB, 4x4)
Windows 7 x64
So the RAM is 2133, but I can't seem to get a full boot. I have tried the XMP profile (and for whatever reason it says DDR3-2000 in BIOS, not 2133 with the XMP), which results in no POST and a cmos clear to get back into BIOS. Entering all the RAM values manually, including the 2133 mhz speed, timings, and voltage allows the system to POST, but the system bluescreens shorty after the 4 spinning colors that appear above the "Starting Windows" screen pops up. So for now, it's running at 1333.
I know the FX chips only natively support 1866, but I figured I could overclock to achieve these speeds. The problem is, I have never overclocked anything besides a CPU so I am new to overclocking any other essential parts to the motherboard that may be required to get this RAM to work. So if anyone could advise me on what to OC and voltages to change to achieve 2133, I would greatly appreciate it. I have read many things from overclocking the CPU to overclocking the northbridge to lowering the HT link speed...I am so confused here.
Also, I know there is little difference between 1600 and 2133 mhz RAM, but I would still like to get the speeds as advertised.
Oh, and this is a full rebuild with all new parts, and nothing is overclocked. Thanks!
