DDR2 memory is bringing the AMD Athlon64 socket AM2 architecture to new levels of performance, and modules like Crucial's 1GB Ballistix PC2-5300 RAM is spearheading that change. For enthusiasts who truly push the limits of computer technology, the juggling match between memory timings and memory speed has just gotten a bit more complex...
You see, the issue revolves around the AMD Athlon64's memory controller and how it calculates the memory operating frequency. To get the memory frequency, you have to divide the CPU frequency with an integer - a whole number like 133, or 200. For Athlon64 processors with an even clock multiplier, there isn't any problem running DDR-2 memory at DDR2-800 speeds. However Socket AM2 Athlon64 processors that happen to have odd number multipliers will need to do a few more steps.
