DIMM
This mainboard has four 72 pin SIMM sockets
(Single-in-line Memory Module) and one 168 pin
DIMM socket (Dual-in-line Memory Module) that
allow you to install system memory from minimum
8MB up to maximum 128MB.
The SIMM supported by this mainboard can be identified by 4 kinds of factors,
Intel VX chipset does not support 64M bit technology.
♦ Size: single side, 1Mx32 (4MB), 4Mx32 (16MB), and double side, 1Mx32x2
(8MB), 4Mx32x2 (32MB).
♦ Speed: 60ns or 70ns access time
♦ Type: FPM (Fast page mode) or EDO (Extended data output)
♦ Parity: without parity (32 bit wide)
The DIMM supported by this motherboard are always 64-bit wide SDRAM,
which can be identified by following factors:
I. Size: single side, 1Mx64 (8MB), 2Mx64 (16MB), 4Mx64 (32MB), 8Mx64
(64MB), 16Mx64 (128MB), and double side, 1Mx64x2 (16MB), 2Mx64x2
(32MB), 4Mx64x2 (64MB), 8Mx64x2 (128MB).
Tip: Here is a trick to check if your DIMM is
single-side or double-side -- if there are traces
connected to golden finger pin 114 and pin 129 of
the DIMM, the DIMM is probably double-side;
otherwise, it is single-side. Following figure is for
your reference.
