2-5 Main Memory Configuration
The DRAM memory system consists four banks and the memory size ranges from
16~512 MBytes. If you only use one bank it does not matter which one you use and
if you use two or more banks, it does not matter which bank you install first.
DRAM Specifications
DIMM type: 3.3V, unbuffered, registered, 64/72-bit Synchronous DRAM with
SPD*
Module size: Single/double-side 16/32/64/128/256 MBytes
Parity: Either parity or non-parity
The compatibility of 512MB and Registered DIMM is still under testing and
cannot be guaranteed.
