The Gigabyte GA-X48T-DQ6 - Redefining the High End?

450FSB BIOS Settings
These settings should prove useful for Q6600/QX6800/QX9650 CPUs, with the Q6600 currently being the most popular (and affordable). If a non boot is experienced when applying these BIOS profiles after a cleared CMOS or BIOS reset - increase tRD shown in the profiles by +1. A looser tRD will help the board complete the initial boot cycle. Re-enter BIOS,move the tRD back down by -1. Remember not to change memory divider/ CAS or Northbridge strap during the same reboot as tightening tRD.

this isn't a typical mobo and it's not being reviewed as such. this article is testing the limits of highest-end board with the highest-end cpus. comparing it to 965 or p35 based mobos makes no sense since a) it's twice as expensive when ram is conisdered and b) the buyer for this type of hardware wants the absolute best performance possible and not the best bang for the buck.Rob94hawk - Wednesday, January 2, 2008 - link
Been running my Corsair CDFN @ DDR3 1800/7-7-7-20 on the X38T board for a couple of days now. E6750 450x8 @ 3.6Ghz finally Orthos stable (With BIOS F2!)http://www.xtremesystems.org/forums/showthread.php...">http://www.xtremesystems.org/forums/showthread.php...
Great review though. A few BIOS tweaks in here that I did not know about that might help me on my quest for 4Ghz on air.
Was thinking about pulling the mobo heatpipes and re-seating them with some MX-2.

I have to agree, but not only that : The X38 DDR2 board from Gigabyte seems to respond in much the same way, and displays the same quirky behaviour the X48 sometimes does.I do hope things get better as time passes, as the "reboot to a messed up bios" problem is really bugging me.

My 965p-ds3 rev.2.0 does the same thing. HA!....... I'm starting to sense a pattern here.....Rob94hawk - Wednesday, January 2, 2008 - link

Hi Rob,Looks like you're running the X38T and not the X48T?

Yes I've got the X38T and it's a great mobo.
