OCZ says the memory modules have been tested to run at 2T. We tested only at 1T since this is where the performance is. Why would you buy an "Elite" memory, and not run it at the fastest setting?


The first test we did, was test how the memory performs at a stock frequency of 200 FSB. We tested both 2-2-2-5 and 2.5-4-4-10 timings. Here you can clearly see how big the performance difference between both timings is.
After this, we tested how far we could overclock the memory at 2.6V. The CL2 timings could only go 6 MHz faster, to 206 MHz, which is not much. However, at CL2.5 the overclocking increase was substantial, at 2.6V, which is 0.2V below OCZ's recommended default voltage, we could gain an extra 45 MHz.
Now we increased voltage in several steps to 2.8V, 3.1V and 3.3V. More voltage does not help the CL2 setting at all which is a bit dissapointing. The lowered maximum clock at 3.3V seems to be caused by the extra heat generated of the memory - we did not use any active cooling.
At CL2.5 the results are completely different, overclocks scale nicely with voltage. The maximum of 282 MHz at 3.3V is quite good.

The last test "JEDEC DDR-400A" is for comparison with a generic DDR module running at JEDEC standard timings.

Running this memory at CL2 timings does not make much sense in my opinion, since your overclocks are rather limited there. You specifically buy TCCD memory for high clocks at less aggressive timings. If you want tight timings you should look at memory which uses Winbond's BH-5 chips, for example OCZ's 3500 Gold Gamer eXtreme.

For easier comparison with other modules, we set a maximum voltage of 3.1V and tested until we found the highest clock frequency and fastest timings for this memory. The benchmarks Everest Read, Everest Write and Quake 3 were run. We then calculated the performance increase in percent compared to some standard DDR-400 memory running at JEDEC standard timings (2.5-3-3-8). The average percentage of the three benchmarks is listed in following table:
