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

Final Thoughts on Overclocking
2GB memory overclocking is still proving unreliable between reboots on this board. We have found the board can run a CAS latency of 6 or 7 between 1600-1800MHz. However, the BIOS can be prone to resetting itself between reboots. A CAS setting of 8 is still where this board seems happy for 24/7 operation on current BIOS releases. Dual-core FSB limits are around 500FSB boot-up from BIOS. Using clockgen we have managed speeds of up to 540FSB for benchmarking the board with water-cooling. For absolute stability, we found 495FSB or so is the maximum limit when using a divider that pegs memory speed to around 1600 MHz.
We fully expect these FSB limits to improve with newer BIOS releases. We also made an attempt at 4GB memory overclocking using Microsoft's Vista 64-bit operating system. Using our QX6800 we managed both 6-6-6-18 1N timings at DDR3-1600 and 450FSB DDR3-1800 1N timings that are shown below (please refer to the BIOS templates for actual BIOS settings).

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.
