The Dominator GT DDR3-2000 triple channel kit defaulted at DDR3-1600 10-11-11-29. That should be a mild enough clock for nearly every X58 motherboard to POST. Actually, those settings didn’t show up on the SPD table, but I don’t think that they were settings that I already had set in the BIOS.
It took some tweaking to get my motherboard to POST with the memory set to DDR3-2000. The overclock that was automatically set when I enabled XMP did not have the VCORE set high enough for the CPU’s overclock, but once I bumped it up, it booted up just fine.
I spent a considerable amount of time experimenting with the Dominator GT DDR3-2000. First I tried to see what kind of timings I could get at DDR3-2000. I was able to get the timings to 7-8-7-24 with rock solid stability. Next, I dropped the speed to DDR3-1600, and was able to get 6-6-6-24. All of this was at a VDIMM of 1.66v. My board doesn’t have odd hundredths, the choice is either 1.64v or 1.66v. I have had trouble in the past getting advertised speeds with 1.64v, so I usually bite the bullet and go for 1.66v.
For outright overclocking, I was able to get the Dominator GT to DDR3-2156 10-9-9-28. The previous high memory speed I have achieved with this motherboard was DDR3-2124. Keep in mind that the motherboard is rated at DDR3-2000, and I really don’t know how high the motherboard and processor’s memory controller will go before they start affecting stability, so one might get a higher overclock with an i7 965 or 975.
