The HOT-591 mainboard provides two 72-pin SIMM sockets and two 168-pin DIMM
sockets that make it possible to install up to 256MB of RAM. The SIMM socket support
4MB, 8MB, 16MB, 32MB, 64MB and 128MB 5V single- or double-side fast page or EDO
DRAM modules, and DIMM socket support 8MB, 16MB, 32MB, 64MB, and 128MB 3.3V
single- or double-side SDRAM, fast page, or EDO modules.
The two SIMM sockets are arranged in a single bank, the two DIMM sockets are arranged in
two banks of one socket each. Each bank provides a 64/72-bit wide data path.
Note:
Maximum memory size is 256MB total for all SIMM or DIMM sockets.
If using SIMM modules, each bank must be filled with a pair of same
modules.
The user should not populate both 5V SIMM modules & 3.3V DIMM
modules at the same time.
The memory configuration tables on next page list the SIMMs and DIMMs memory configu-
ration.
