Hardware Setup
This mainboard supports 3.3v, unbuffered, 4-clock, SDRAM DIMM only,
Buffered, 5V, or 2-clock SDRAM DIMMs should not be used.
This board has DIMM (Dual-in-line Memory Module) sockets to support
SDRAM type DRAM and has the better optimized read timings (7-1-1-1).
The DIMM sockets will quickly replace SIMM as the next module standard
for the PC industry and will become the memory subsystems standardized 64-
bit data interface. Recently, JEDEC committee passed the unbuffered DIMM
pinout specification as a standard for higher speed transfer. The unbuffered
DIMM allows for SDRAM and FPM DRAM compatibility as well as pinouts
for x64, x72 with parity, x72 with ECC and x80 ECC. The unbuffered DIMM is
distinguished by the keyed notch lying to the right of the centerline of the
DRAM key position as shown in the figure below.
