Corsair XMS TwinX 1024MB PC4400 DDR Memory

Test Setups & Benchmarks Used:

For our testing we used an Intel 3.2C ES (engineering sample) processor The reason for this is that it allows us to adjust the multiplier and keep the CPU speed at a reasonable level. The lower multiplier helps to achieve a much higher FSB since we will also be overclocking the CPU.

For our testing procedure, we used MemTest86 to check for stability, SiSoft Sandra 2004 SP1, and PCMark04 for our benchmarks. Also if we say "stable", it means that the memory was stable through many loops of MemTest86. If the memory could not run through MemTest86 without giving errors, we did not even bother to boot into windows and run the benchmarks.

When testing memory, there are a million different ways one can test it, timings, voltages, FSB, all play an important role. However, since this memory was designed for the Intel 875/865 platform, that is all that we are going to test on. Also since this memory is tailored as a high FSB product, we are not going to attempt to find out the tightest timings at various speeds.

We report the memory results at these different speeds:

• 200FSB/DDR400/PC3200 - the highest stock speed supported on 875/865 motherboards.
• 250FSB/DDR500/PC4000 - the average good OC for most system, it's a nice round number.
• 275FSB/DDR500/PC4400 - the specified rating of the memory modules we were testing. (These numbers will be in bold italic for easier reference)
• Highest Stable Overclock - the highest settings we could achieve with the memory being tested.
• Highest Stable Overclock w/vmod - same as above, but with a vdimm mod to allow higher voltages.
