2.4 Configuring the System Memory
Pin1
The DIMM type supported is PC100
SDRAM (Synchronous DRAM) only.
This motherboard has two 168-pin
DIMM (Dual-in-line Memory Module)
sockets that allow you to install system
memory up to 512MB.

DIMM modules can be identified by the 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).
(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. The following figure is
for your reference.

II. Speed:
normally marked as -12, which means the clock cycle time is 12ns and
maximum clock of this SDRAM is 83MHz. Sometimes you can also find the
SDRAM marked as -67, which means maximum clock is 67MHz.
