Your overclocking results graphs should either go to zero on the dependent axis or include results from another setup for comparison. Without doing one of the two, the bar graph picture tells us nothing at best, and is misleading at worst.

Sorry to harp, but I just want to help. Your review is very useful and well done otherwise.

Do you know if VT-d is working on this mobo? X58 chipset have this feature but sometimes it doesn't work. I'd like buy this mobo and install ESXi 4 (or XEN) with VT-d (VMDirectPath). Anybody test VT-d on this motherboard?

Sorry for my bad english

Yes, I have ESXi 4.0 Update 1 installed on this motherboard. Can't get ESXi to recognize RAID — keeps seeing the individual disks, but ESXi is running great, including a 64-bit VM, so VT-d is working.

I Have this board know and i cant get windows 7 to install! really anoying. please help!!!!!!!!!!!!!!!!

Windows 7 installer freezes with the hard disk and optical drive hooked up to the Southbridge-powered SATA ports. Workaround: install Windows 7 with the drives connected to the Gigabyte SATA2 controller. After the successful installation the Southbridge-powered ports work.

VT-d is for directed I/O, a feature of the chipset used to map hardware directly to virtual machine, it's not the same as VT, the CPU feature used to run 64 bit virtual machine.
So, your answers is not correct.

Before you run out and buy one of these, google the MB and the terms “High pitched noise, or “whine”.
This board and it’s next two higher (UD5 & UD7) priced x58 cousins have been having problems with a VERY ANNOYING whine, sort of like a cat fight. Most folks think it’s the chokes. Gigabyte has been releasing bios updates to cure a hardware problem. To date, no cure despite revision 2 releases of the board. Google the board before you buy. There are videos on youtube of the problems.
