Memory Upgrade
The system memory is upgradable to a maximum of 256 MB via two 168-pin DIMM sockets on board. These DIMM sockets accept 3.3 Volt PC-66/PC-100 compliant SDRAM DIMMs with 8, 16, 32, 64, and 128MB capacities.
Important! Do not use both PC-100 (100 MHz) and PC-133 (133 MHz) SDRAM together. Such a combination might cause your system to malfunction.
Adding RAM is the most cost effective way to boost your computer's performance.
