This motherboard features two Double Data Rate (DDR) Dual Inline Memory Mod-
ule sockets and three Single Data Rate (SDR) Dual Inline Memory Module sockets.

Double Data Rate Synchronous Dynamic Random Access Memory (DDR SDRAM)
of 64MB, 128MB, 256MB, 512MB, and 1GB to form a memory size between 64MB
