We will be testing this memory at lowest timings at the highest FSB, because that's what enthusiasts are using to get maximum performance out of their memory.

Performance

The first test we did, was test how the memory performs at a stock frequency of 200 FSB. We tested both 2-3-2-5 and 2.5-4-4-8 timings. The modules' SPD at 200 FSB is 3-3-2-8. Here you won't see a very fair comparison because the processor is running at 3.6 GHz opposed to the 2.8 Ghz it is running at 2-3-2-5. But you are able to see how much the processor speed affects the results of the benchmarks.
During testing I used 2.8V just to keep the voltage at a constant. I found that slight voltage increase to 3.14 gave me head room to hit 280 FSB at 3-3-2-8 but it was very unstable and thus I conclude that more voltage doesn't make a huge difference.
I also do not feel safe running any RAM in my computer above 2.8 V for 24/7 use because in most cases memory is only meant to run higher voltages for benchmarking. The last test "JEDEC DDR-400A" is for comparison with a generic DDR module running at JEDEC standard timings, but once again my processor was using a 18x multiplier.

Now this memory is very versatile, its got some really great bandwidth and timings for a 2 GB kit. At 230 MHz it was running timings tighter than most TCCD and TCC5. At 265 is was running with timings tighter than some BH-5 and all TCCD and TCC5 chips. I found the RAM to be max. Video Bench stable at 280 and SuperPi and Bandwith benchmark stable at 286. My results were done on a i865 platform which doesn't have a strong memory controller like the Athlon64, FX, and X2 series of AMD processors. But just these results prove that this memory is great on all platforms.



For easier comparison with other modules, we set a maximum voltage of 2.8V 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:
