Overclocking the RAM
The modules themselves are quite aggressively timed for modules hitting past 600MHz or 1200MHz DDR. Corsair rates their modules for 5-5-5-18 2T at 625MHz. Last week we checked out the impressive OCZ FlexXLC memory and it had to lower itself down to 5-9-9-24 2T just to hit 600MHz.
With our new Gigabyte P965-DQ6 rev 3.3 test system motherboard we managed to hit a total of 627.5MHz or 1255MHz DDR (which works out to be PC2-10040) with the timings still staying at 5-5-5-18 2T. We did manage a speed of 634MHz or 1268MHz DDR to load Windows XP but any attempt to load benchmarks resulted in a total system shutdown and reboot. To get as high as we used the full 2.4 volts that the modules specify.
Another site managed to break 1300MHz DDR but it's of course going to depend on what motherboard you are using along if you get the sweetest pick of the batch. We're pretty impressed anyway to be running memory at speeds above PC2-10000.
To see what was possible we lowered the timings as tight as possible at 800MHz DDR. In this instance we got 4-3-3-15 2T out of the modules, which is quite aggressive, and this was without any voltage increase to the modules.
If we had a little more time with the modules we would have tried some voltage increases to see if we could have gotten more out of them. We had only a short time to test - we were impressed with what we got on our first attempts but if you've got more time to invest in pushing the modules to the absolute maximum, you'll more than likely see better results.
