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).
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.
168

Pin 129
Pin 114
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.
