I couldn't get my DFI LP UT X58 with the 0106 BIOS and my 920 to boot with a BCLK above 170. I've flashed the BIOS to 0114 using a bootable USB drive and will see if that helps. I started with the BIOS setting in the first post and adjusted them to my system.

I tried both Vista 64-bit SP1 and XP Pro 32-bit SP3. I suspect that I'll be doing a major swap of components with my P6T sooner than I anticipated.
