3.10 DRAM Installation
The S1472 uses a 64-bit data path from memory to CPU and can
accommodate up to 128 MB of RAM. The mainboard supports Fast
Page Mode, and EDO (Extended Data Out) 72 pin SIMMs.
SDRAM(Synchronous) are also supported in the DIMM slots. DIMM's
must be of the unbuffered variety. All installed memory will be automati-
cally detected so there is no need to set jumpers.
wSIMM modules must be installed in pairs.
wEach pair of SIMMs must be of the same size and type.
wThe mainboard supports 1, 2, 4 and 8MBx32 SIMMs.
wSIMM bank 0 and 1 can use either double or single sided SIMMs.
wTwo SIMMs or One unbuffered DIMM must be installed for the system
to POST.
wSDRAM DIMMs can be installed one at a time.
wThe mainboard supports 1, 2 and 4Mx 64 DIMM modules.
wSIMM bank 0 and DIMM bank 0 cannot be used at the same time.
SIMM bank 1 and DIMM bank 1 cannot be used at the same time.
You can use SIMM bank 0 with DIMM bank 1.
You can use SIMM bank 1 with DIMM bank 0.
