Being a dual-channel kit, PMI is clearly targeting the Intel user as the performance gains on the AthlonXP platform aren't nearly as great. The PMI DDR400 was tested at DDR400, DDR433 and the highest stable overclock speeds.
Basic stability was first tested using Memtest86 v3.1. If any memory errors are detected, the memory timings, speed, voltage or some combination therein are adjusted. Once eight Memtest86 passes are successfully completed, the stability results are confirmed by performing 3 passes of makeworld -j4s under FreeBSD 4.9. Finally, performance results are obtained via SiSoft Sandra 2004's unbuffered memory test.

Delivering on the promise is a trial by fire for any new name in performance memory. The PMI3200-512DG is honestly rated and performs with the utmost stability at its rated speed and timings. It even has quite a bit headroom, being able to run reliably at either lower latencies (DDR400 2-3-2-5 @ 2.8V) or higher speeds (DDR433 2-3-2-5 @ 2.8V). The maximum speed we were able to achieve was DDR440 (3-4-3-8) at 2.8V and a 1T command rate. While falling short of what the legendary Winbond BH5 chips could achieve, this is still a pretty solid overclock.
