I just started playing with mine X48 LT T2R and I'm not too happy. Every time I add any voltage to the CPU (Q9450) the stupid bios asks me to insert a boot CD. Even if I disable the CD ROM as a bootable device and unplug it from the computer.
It got stuck so bad once I had to re-install windows already. I also noticed it will sometimes change the boot priority of the hard drives when I change the CPu voltage and save. But it was certainly set correctly the last time when I had to re-install and it was suddenly not able to find the OS (tried booting it at 3500MHZ) I'm not too happy with my purchase right now but I still need to try flashing the bios... I can boot up 400FSB without adding any voltage to the CPU, but over 400FSB I get the stupid insert boot CD as well. So right now I have my Q9450 @ 3200MHZ, seems stable off default voltage, but I can't seem to go any higher.
