Performance

As first test we ran the memory at 200 MHz, at the standard voltage of 1.8V, to see how it performs at everything set to stock. The next test determines the maximum overclocking at 1.8V, which is something you would experience if your motherboard does not allow memory voltage adjustments at all.
For the next three tests we raised voltage in steps to 1.9V, 2.0V and 2.1V. As you can see the overclock scales very nicely with voltage. Further increasing the voltage did not help much. At 2.3V we saw about 375 MHz which is not worth it for the reduction of life span this brings.
In the next test we reduced the timings to 3-3-2-4 which are the tighest timings this memory can run at. The best timings you can set in the Intel chipset are 3-2-2-4, so what is possible with this memory is close to the fastest setting possible.
Next we tried to relax the timings to 5-5-5-15 to find out if we could get a higher maximum overclock out of the memory than at 4-4-4-12 which isn't the case.

For further comparison, the test "JEDEC DDR2-400" shows a generic DDR module running at JEDEC standard timings.

For an easier comparison with other modules, we set a maximum voltage of 2.1V 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 a generic DDR2-400 memory running at JEDEC DDR2-400 (4-4-4-12). The average percentage of the three benchmarks is listed in following table:
