OCC has published a new review on the CSX Diablo PC3 16000 DDR3 2x1GB

Try as I might, I could not push the Diablo modules any further than the 2000MHz they are rated for. They ran the same 2000MHz whether the timings were tightened up or loosened up even further than the 9-9-9-28 stock latencies. Increasing the voltage was not the solution this time it seems. 2.2 volts did not bring any gains to the maximum clock speed or to the timings. At the 1333MHz mark the modules easily ran 6-5-5-15 all day long with 1.75 volts to the modules. Since I could not break through the 2000MHz mark, I started tightening up the sub-timings and was able to drop them to 8-7-6-20 at the same 2.04 volts that the modules ran the looser timings. Without a processor to push a higher FSB speed on this platform, I had to settle for the reduction in memory sub timings. This tightening of the timings offers up an increase in performance that you can't pass up.
