3.10 DRAM Installation
The S1572 uses a
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, 8 and 16MBx32 SIMMs.
wSIMM bank 0, 1 and 2 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.
wIf you use 4Mx64 DIMMs you cannot use DRAM bank 2.
wWe do not recommend using DRAM bank 2 along with DIMMs.
wThe following table shows some of the available memory configurations.
