PQI's PQI24200-1GDB DDR2 Turbo Memory Kit

Performance at BY SPD Overclock

For next round of testing we set each kit to run with their SPD timings and raised our test system's FSB as high as possible.  We didn't have an unlocked processor to isolate the memory from the CPU, but we ran the test with a 3:4 divider and increased the bus accordingly.  We found the peak bus speed with the PQI memory was 220MHz, where it topped the Corsair at 216MHz.

Performance Comparison with SiSoft SANDRA 2004
Raw Bandwidth

PQI24200-1GDB (3-3-3-8)
220MHz FSB/ 293MHz (DDR586)

XMS2-5300Pro (3-3-3-8)
216MHz FSB / 288MHz (DDR573)

Running the PQI memory at a higher overall bus speed didn't mean it was the best performer while overclocked.  Here, we see the Corsair memory was still faster, even with a bus clocked 4MHz slower than the PQI scenario.  The Corsair XMS2 managed the faster overall result, with a difference of roughly 80MB overall.

Performance Comparison with PCMark04
Overall Memory Score

This time around, the PCMark04 scores didn't follow the same pattern as SANDRA.  Here, we see the PQI24200 Turbo series beat out the Corsair XMS2 by 17 points overall.

In-Game Performance Comparisons With Wolfenstein: ET
System Memory Affects Framerates?  You Bet!

The Wolfenstein: ET scores were still a tight match up, with the PQI memory taking a 2.4 frame lead over the Corsair modules.  In the final segment, we're going to raise the latencies and see just how high we could go with our test bed.
