Depending on the model of the older S288x, the BIOS/APIC
registers might only support 166MHz DDR (DDR333/PC2700)
synchronous clock for the memory, even though the CPUs
support 200MHz DDR (DDR400/PC3200).  Haven't checked BIOS
updates on that because I haven't had really any of those
boards, although you'll probably want it for the dual-core
CPU support (if there is one available).

The newer S289x were clearly designed with 200MHz DDR
(DDR400/PC3200) in mind, as well as dual-core processors.

BTW, the memory capabilities have _nothing_ to do with the
HyperTransport chips used for I/O.

I.e., the 288x is AMD8151, AMD8131 and/or AMD8111
combinations.
The 289x is nForce Pro 2200, nForce Pro 2050 and/or AMD8131
combinations.
Those have to do with I/O and peripherals.
