2.1.5. Upgrading System Memory
The R653 mainboard can use Six- 72pin SIMMs, system DRAM memory
can be upgraded from 8MB to 384MB, The DRAM type can be used Fast
Page Mode (FP) and Extended Data Output Mode (EDO) or BEDO Mode at
the each Banks. The same Bank must use the same type of DRAM.
You must use 2 Module at a time (one Bank), that is. SIM 1 & SIM2 ,
SIM3 & SIM4, SIM5 & SIM6, (at least one Bank On-board).
Each pair of modules must be the same size and speed and can be
either single or double-sided.
DRAM Type : Fast Page Mode(FP) or Extended Data Output(EDO)
or BEDO Mode.
DRAM Speed : 70ns or faster.
Parity : Either parity or non-parity.
(Require Parity Memory to Support ECC)
Installing SIMMs
To install SIMMs as following instructions:
1. The modules will only insert in a socket in one orientation. An orientation
cut-out will prevent you from inserting them the wrong way. See the figures
at right.
2. Press the module edge connector into the socket at a moderate angle to the
board. See the figures below.
3. Press the module forward onto the socket's vertical posts, so that the
alignment pins at the top of each post go into the circular holes at each end
of the module.
4. The module should click into place, as the retaining clips at each end of the
socket snap behind the module to secure it.
5. Repeat this procedure for each module you install.
