OCZ Reaper HPC DDR2 1066 2 x 2 GB Review
 

I wanted to see how far I could get the memory to go, so I started playing with numbers. The highest overclock I could get was 1167MHz, but to get there I had to loosen the timings all the way to 5-8-8-22. At these timings, the scores were lower than the stock speeds so they were not usable as an overclock. The sweet spot that I found for the best performance was at 1120MHz with the stock timings of 5-5-5-18. This gave a slight improvement and was thoroughly stable. These are the scores I am going to use for overclocked benchmarking later in this review.
