PQI PC4000-1024DBL TURBOmemory DDR Modules

Test Setup & 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 SP2, and PCMark04 for our benchmarks. Also if we say "stable", it means that the memory was stable through many loops (minimum of 5) 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. We try to test the memory as many different ways as possible, however we simply can't try every single combination MHz by MHz.

For this review, we will be reporting the memory results at these different speeds:

• 200FSB/DDR400/PC3200 - The highest stock speed supported on 875/865 motherboards.
• 250FSB/DDR500/PC4000 - The specified rating of the memory modules we were testing. (These numbers will be in bold italic for easier reference)
• 266FSB/DDR533/PC4300 - The highest speed achieved with the rating timings.
• 275FSB/DDR500/PC4400 - PC4400 is a popular speed and is a nice round number.
• 280FSB/DDR560/PC4480 - Highest Stable Overclock - the highest settings we could achieve with the memory being tested.
