System Memory; Dimm - DFI 586ITX User Manual

System Memory

The 586ITX system board supports two kinds of memory modules:
DIMM and SIMM. DIMM, which uses SDRAM, performs better than
SIMM, which uses DRAM. Refer to page 12 for the locations of the DIM
and SIM sockets.
Important:
DIM and SIM modules can not exist on the 586ITX system board at the
same time. Use either SIMM or DIMM only.

DIMM

The two 168-pin DIMM (Dual In-line Memory Module) sockets use x64
EDO, FPM and SDRAM. The 586ITX system board can support 8MB to
32MB memory using 1MBx64, 2MBx64 or 4MBx64 DIMM. The table
below shows the supported DIM modules and their corresponding
memory sizes.
The table below summarizes the DIMM sockets and modules needed
for the corresponding memory sizes.
