Problem with memory

I just built a new machine running an i7 860 on a Gigabyte GA-P55M-UD2 using G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-4GBRL.

I noticed a problem with the memory timings being reported in CPU-Z. The CAS# Latency is showing up as 4.0 clocks - when it should be showing up as 9.0. After doing some digging, I found an error message being reported in Computer Management - in the System Log. I believe this error occurs when the computer either goes into or wakes up from sleep or hibernate.

Any thoughts on how to fix this? I'm running Windows 7 RC x64. I have XMP turned on. And I upgraded the board BIOS to F4g hoping that would fix the problem but it didn't.

Here's the error from the system log:
Source: HAL
Event ID: 12
General message: The platform firmware has corrupted memory across the previous system power transition. Please check for updated firmware for your system.

I wouldn't use the XMP profile. Just manually set the RAM speed/timings/voltage to the recommended specs. That would be 1600MHz with 9-9-9-24 timings at 1.5v for your RAM.

I have also tested this running default RAM settings in the BIOS (that is, XMP = Disabled, speed at 1333) - in which case CPU-Z reports the RAM running as:
~683.5MHz - 2:10 - 9.0 - 9 - 9 - 24 - 74 - 1T

But when it goes to sleep and then after I wake it up I find the same HAL corrupted memory error and CPU-Z then reports the RAM as running as:
~683.5MHz - 2:10 - 4.0 - 9 - 9 - 24 - 74 - 2T

So after waking from sleep both the CAS Latency and the Command Rate are corrupted.

Thanks for the link. So you think I'm at the mercy of waiting for Gigabyte to fix the problem in an BIOS update?
