OCC has published a new review on the A-DATA Plus-Series DDR2 800 2 x 2GB

I wanted to see how far I could push the memory within the modules' limits and still get good scores. The sweet spot for the overclock I reached was 1066MHz, and all I had to do was bump the voltage to the 2.1v maximum specification and loosen the timings to 5-5-5-12. This gave me a 266MHz overclock, which is a 33% bump. Now that is a great speed increase for a set of memory modules. Everything ran stable and I had no problems with the benchmarks or Memtest86+ with these setting, so that is where my overclocked numbers will be run.
