Compatible DRAM DIMMs must meet all the following
specifications:
• PC-100 Synchronous DRAM (SDRAM)
• 3.3 volt
• 64-bit wide, 168-pin module
• maximum of 16 memory devices on the DIMM
• unbuffered; do not use registered or buffered
Synchronous DRAM (SDRAM)
• maximum height of 2.0 inches.
To increase DRAM to the maximum of 1024 MB, fill all four
slots with 256 MB DIMMs. Any 256 MB DIMMs installed
must use 128 megabit (Mbit) device technology.
