2.4 Configuring the System Memory
PIN1
The DIMM types supported are
SDRAM (Synchronous DRAM) only.
This motherboard has three 168 pin
DIMM sockets (Dual-in-line Memory
Module) that allow you to install system
memory up to 512MB.
In case you install SDRAMs on
DIMM2 and DIMM3 at the same time,
it is crucial to identify single/double
side. For this configuration, only
single-side SDRAMs are acceptable.
Warning: This motherboard does not support Registered
SDRAMs and EDO DRAMs.
Warning: If you install two double-side SDRAMs, the possible
combinations are DIMM1&DIMM2 or DIMM1&DIMM3.
Warning: The maximum of 512MB can be implemented by
installing two 256MB SDRAM modules.
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.
