Memory can be increased to a maximum of 384 MB by installing combinations 
of 3.3-V, 32-, 64-, and 128-MB non-ECC DIMMs in the three DIMM sockets on 
the system board. Only 100-MHz DIMMs are supported. 
NOTE: The system is designed for peak performance with specific DIMMs that 
are validated through rigorous testing. The system may not recognize other 
SDRAM DIMMs and may fail power-on self-test (POST).
For more information about the memory configurations, see “Adding Mem-
ory” in Chapter 2 of the 
Reference and Troubleshooting Guide
