#1 This is odd, ET6 has no problems on my motherboard. Make sure you are using the latest version from their site, NOT the one on the original included disc. (Mine's the 4/17/2009 Build)
#2 This occurs with most software that makes changes within windows from what I know. As everyone has said, make changes in the BIOS to work around this, it's much more stable this way anyway.

As someone had asked:

IOH is the X58 "northbridge" This is the I/O Hub, hence IOH
ICH is the X58 "southbridge" Standard ICH10, just like the ICH9, ICH8, etc before it.

Has anyone verified what the Gigabyte Performance Enhance setting changes now? I tested Turbo and Extreme, but all of the RAM timings/subtimings remained identical... since the IOH is not the MCH anymroe, what is this setting good for?

Sparda, I'm looking at your BIOS settings... why do you have EIST still enabled? This is speedstep, you want to turn that off for high overclocking. Uncore frequency depends heavily on each individual chip, regardless of batch# or anthing else. Chips in the same batch as mine can hit 4GHz Uncore fully stable, mine can't go much above 3.6GHz without going unstable, so I use the 18x setting. Since your memory has an XMP memory profile, you might want to enable that rather than manually setting the correct memory timings. I'm using VTT = 1.3v and IOH = 1.2v for my sig overclock, but I've not attempted to lower these settings further yet.
