Reconfiguring Your Mainboard – 3.5
Adding System Memory
There are some requirements you must follow if you want to
install system memory. The memory subsystem has four 72-pin
SIMM sockets divided into two banks, SIMM1 & SIMM2 and
SIMM3 & SIMM4. It also has two DIMM sockets. You cannot
use SIMMs and DIMMs at the same time on this mainboard.
SIMM modules should use either Fast Page Mode (FPM) or
EDO 5-Volt DRAM. You can use modules from 4MB to 128MB,
either single or double-sided. DIMM modules must use 3.3-Volt
unbuffered EDO or SDRAM. Total supported memory capacity
is 384MB.
If your mainboard is already installed in a system, it will have
some amount of memory installed on the board. You can tell
how much by checking the configuration screen that appears
when the computer is starting up. With some memory installed,
there may be sockets available to add additional memory. If not,
you must remove modules to install an upgrade.
It is possible to install more
memory than the board sup-
ports, e.g. four 128MB SIMM
modules would total 512MB,
but the board would ignore
128MB of that. Do not install
more than 384MB on this
mainboard.
You can not use SIMM and
DIMM modules at the same
time on this mainboard.
