MSI X58 Pro with XMP Memory issues

I recently built a Core i7 system using a MSI X58 Pro, and I decided to buy OCZ XMP-Ready 1600 MHz RAM (3 x 2 GB). However, when I enable an XMP Profile in the Cell Menu (be it "profile 1" or "profile 2"), Windows doesn't boot. I've been running it now at 1113.2 MHz (it defaulted to 1066 and after OCing the CPU it went up) with no problems, but I was wondering, does the X58 Pro even support XMP Profiles? If so, how do I get it to work at full 1600 MHz? These are my specs:

Core i7 920 @ 3.710 GHz | MSI X58 Pro | OCZ XMP Ready Series 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) | Sapphire Radeon 4850 X2 2GB | Cooler Master Hyper N520 CPU Cooler | Corsair TX850 PSU | Windows 7 Beta x64

On a side note, CPU-Z lists my RAM as PC3-8500, but the box says that it's PC3-12800. Why?

This is my first solo build and on the P4 system I my dad and I built we didn't have to deal with XMP profiles and stuff.

  1. Hi, i was having the exact same problems! i dont have the same parts but i couldnt get windows to boot either with xmp enabled
  2. I think some motherboards just don't support XMP profiles... I just manually set the clocks to XMP specs and it works fine now.
