The way to verify that one set of memory modules is better than another is to run a series of benchmarks and gather some basic comparison data. When all things are equal and the only variable is the module being tested, the results are a great way to compare performance. In order to eliminate the variables, the only settings that will be manipulated will be the memory timings and voltages when overclocking. The comparison modules will be run at the manufacturer specified timings and voltages at a speed of 1333MHz. In order to reach 2000MHz, the processor used in the test setup will have to be overclocked from 333MHz to 450+ MHz. All of the comparison modules were run at 1333 MHz, the CSX Diablo modules were run at both 1333 and 2000MHz. The memory and CPU were run in unlinked mode throughout the testing.

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.
The benchmarks used in this review include the following:
