Performance Test ConfigurationThe Memory testbed for evaluating PMI4200 Gold is the same used in our earlier reviews of DDR500 and other High-Speed Memory.
Samsung PC3700: DDR466 Memory for the Masses
Kingmax Hardcore Memory: Tiny BGA Reaches For Top Speed
New Memory Highs: Corsair and OCZ Introduce DDR550
OCZ PC3700 Gold Rev. 2: The Universal Soldier
OCZ 4200EL: Tops in Memory Performance
Mushkin PC4000 High Performance: DDR500 PLUS
Corsair TwinX1024-4000 PRO: Improving DDR500 Performance
Mushkin & Adata: 2 for the Fast-Timings Lane

Since PMI rates the memory at DDR533, this memory is clearly aimed at the Intel user. Therefore, we only tested performance on our Intel test bed. We did verify that the PMI DIMMs would run on an Athlon 64 platform and had no problem running 2 DIMMs on the Athlon 64 platform at DDR400. However, we did have to lower CAS to 2.5 from 2.0 for best stability on the A64 platform. While this DDR533 memory will certainly run on A64, it is not a memory that we would choose for an Athlon 64 platform. DDR400 to DDR500 with faster memory timings would be a better choice for an Athlon 64 system.
Test SettingsThe following settings were tested with PMI DDR533:
1. 800FSB/DDR400 - the highest stock speed supported on 875/865 and K8T800/nF3/SiS755 motherboards.
2. 1000FSB/DDR500 - the maximum speed that many current Intel 865/875 boards can achieve.
3. 1066FSB/DDR533 - the specified rating of the DDR533 memory modules.
4. Highest Stable Overclock - the highest settings we could achieve with this memory and other memory that we have tested.
These are the same general settings used in benchmarking other memory in the above list of memory tests. DDR400, DDR500, and Highest Memory Speed have been used for all benchmarking. DDR533 has only been tested in the past for modules with this speed rating.
