Memory
The four DIMM sockets on board accept using 64-, 72-, 128-, 144-,
512-MB and 1-GB SDRAM (synchronous DRAM) DIMMs for a maximum
memory upgrade capacity of up to 4 GB. For data integrity, the default
setting of the ECC (error-correcting code) function of the memory
system in BIOS is enabled. See “Memory/Cache Options” on page 87
for more on this BIOS setting.
