When I first installed the ReaperX, I forgot to change the memory settings in the BIOS, and the first evening, it was running at DDR2-1067, with timings set at 5-5-5-15, and VDIMM at 2.1v. I ran one stick for an hour or so, then added the other. It ran ok for a couple of hours, then bluescreened. I rebooted, and it ran another couple of hours. I thought the RAM was defective, so I pulled it. It hit me out of the blue a couple of days later what had happened.

So already I know it performs better than the 2 gig kit of PC2-6400 Reaper I had, which would not boot at anything above DDR2-960 or so, and wasn't stable above DDR2-950, even with the timings loosened to 6-6-6-18.


My first attempts were with the timings at 4-4-4-15. DDR2-849 was about as high as I could get with solid stability. I loosen the timings to 5-5-5-15, and got all the way to DDR2-1059. To be honest, I was just hoping to get the ReaperX to DDR2-1000, but I still had plenty of room left. I loosen the timing to 6-6-6-18, just to see how far it could go. No luck. I raise the voltage to 2.15, then 2.2. DDR2-1059 is the highest I can get the ReaperX stable. I'm quite pleased with its overclocking performance; getting over 32% overclock at stock voltage is pretty impressive.
