1.5 Hardware Configurations
1.5.1 Memory Configurations
The system board comes with eight 72-pin SIMM sockets that support 4-MB and 16-MB single-
density SIMMs as well as 8-MB and 32-MB double-density SIMMs for a total system memory of
256-MB. The sockets support both the fast page mode and EDO 60/70 ns SIMMs.
Rules for Adding Memory
•You may use the memory banks (Bank0 ~Bank3) in any order.
•Use only one type of SIMM in a given bank. You may combine EDO or fast-page mode
SIMMs for a memory configuration as long as the SIMMs in each bank are of the same type.
•Use only SIMMs with the same capacity in a bank. For example, do not combine 8-MB and
16-MB SIMMs in a bank.
•Always install SIMMs in pairs. For example, for a total memory of 16 MB, install two 8-MB
SIMMs in a bank. You can not use a 16-MB SIMM alone for a 16-MB memory.
