Overclocking - by SPD Testing

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.  This is where the PDP Patriot modules shined.  We managed to hit a solid 233FSB, increasing the memory to 621MHz DDR.  This was an excellent gain, especially without having to tone things back with the timings.  The only thing we did was set the memory to run at 2v and the modules ran great and remained stable through the next range of tests.

Performance Comparison with SiSoft SANDRA 2004
Raw Bandwidth


PDC22G4200+XBLK (3-2-2-4)
233MHz FSB / 306MHz (DDR621)

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

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

Naturally, at significantly higher bus speeds than the reference modules, the PDP Patriot series was the fastest set in the group.  Additionally, these were the only DIMMs to top even SANDRA's internal set of memory scores.  On average the memory ran at a 5800MB/s at DDR621.

Performance Comparison with PCMark04
Overall Memory Score

We saw a sizeable gain in score with PCMark04's memory module, obviously beating out the competitors as well as posting solid gains over its stock results.  We saw a healthy 858 point increase, average out to a 16.68% boost in performance.

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

In the last test, we saw less drastic differences in score with Wolfenstein: ET.  Here, the closest margin was between the PQI and PDP modules, with the Patriot series take a 5 FPS lead.  Overall, the PDP Patriot memory added 13.6FPS over its stock results, equalling 11.3%.
