One thing that stands out for us is that overall memory access latency is below the figures we have come to expect from DDR3 on the X38/X48 chipset. Although not shown here, this pattern also continues to the 65nm process CPUs. Apart from tRD and the finicky tRD phase shifts (see the BIOS guide later in this review), there are no other chipset registers we can access to easily increase 1N latency performance. We even tried an E6850 to see if increased levels of FSB would allow a linear scaling of memory access latency. Again, the figures were off the pace, coming in around 57ns at 500FSB (3.5GHz) with a tRD of 7. How this pans out into real world benchmark tests is always interesting, especially as most 3D game engines seem ambivalent to overall chipset performance.

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.
