Today's test system is using the X38 with DDR3 based memory support from GIGABYTE. This board is due for review very soon; we can't clock the board as much as we can the memory, so bus speeds are kept down.
Today we are looking more at the XMP side of things, and to keep things fair we are using Corsair's Dominator 1800 memory modules. However, we have limited the speeds on this to a total of 826MHz for both on the overclocking side. For our XMP tests, we ran the system using 1600MHz memory by clocking the system with a 400MHz FSB which allows the memory to run at 1600MHz on a 1:2 memory divider.
We did tests with the XMP system on running 7-6-6 timings and off with 8-8-8 timings. The Corsair at 1600MHz ran with timings of 7-7-7 as standard with voltage up to 1.55v, it unfortunately refused to run at this speed with default 1.5v. OCZ with XMP off would run 1066MHz with 8-8-8 / 1.5v default, so a big plus here. To get 826MHz out of the OCZ we had to go to 1.95v with 8-8-8-28 to make it run. Corsair did this with 1.8v and 7-7-7-20.

EVEREST Ultimate Edition is an industry leading system diagnostics and benchmarking solution for enthusiasts PC users, based on the award-winning EVEREST Technology. During system optimizations and tweaking it provides essential system and overclock information, advanced hardware monitoring and diagnostics capabilities to check the effects of the applied settings. CPU, FPU and memory benchmarks are available to measure the actual system performance and compare it to previous states or other systems.
With the XMP system off the Corsair and OCZ are almost identical in bandwidth; turning XMP on gave the OCZ its extra wind and managed a few more MHz in the bandwidth but really nothing to write home about.
