AMD Athlon64+ 3800 & FX53

The Athlon64 CPU was one of AMD's most important products and, for good reasons, it has been quite successful since its launch late last year. At that time, AMD released the Socket 940 based AthlonFX CPU as well as the Socket 754 based Athlon64 CPU. The FX offered higher performance by utilizing a dual-channel memory controller built on the CPU while the Socket 754's memory controller only offered a single channel. Unfortunately, the FX only accepted registered memory modules which aren’t as easily or cheaply available as your standard non-ECC memory especially at higher speeds like DDR400.
