Overclocking - Highest Stable Clock

For our final round of tests, we set the PDP Patriot memory to run at 4-3-3-12 and compared it to the other modules at 4-4-4-12.  We then raised our test system's FSB as high as possible, resulting in 251MHz, the highest attainable for this board.

In this round, the PDP Patriot and Corsair memory managed to come up virtually tied, with a slight edge in favor of Corsair.  The Patriot modules maintained a 1MB/s lead in the Integer test while slipping 4MB/s in the Floating point segment.  The PQI memory weighed in an average of 100MB/s slower than the other two sets.

Here, the PDP Patriot memory lagged Corsair by a small 7 point margin, where the PQI set fell by 85 points.

Our final test was with Wolfenstein: ET, where the PDP Patriot memory eked out a top spot by a fraction of a frame over the Corsair XMS2 series modules.  Again, the PQI modules came in last, slipping by roughly 2FPS, a very close third position.
