2-3 SYSTEM MEMORY INSTALLATION
ATC-5030 provides four 72-pin SIMM sockets for system
memory expansion from 4MB to 256MB. These four SIMMs are
arranged to two banks, Bank0 (SIM 1, 2) and Bank1(SIM 3, 4),
please refer to page A. Each bank provides 64-bit wide data path.
The mainboard accepts Fast Page Mode DRAM, and EDO
Mode (Extended Data Out) DRAM, with a speed no slower than 70
nanosecond. You should plug DRAM modules into two sockets
(same bank) or four sockets at one time. Each pair of modules in
the same bank must be the same size, type, and speed; no matter
single-side or double-side module. Please plug in Bank 0 firstly if
you only have 2 modules. The mainboard supports mixing of EDO
and fast page mode DRAM among different banks, please plug
EDO in Bank 0.
Also this mainboard provides two optional 168-pin DIMM
sockets for 3.3V SDRAM or 3.3V EDO DRAM expansion. You
should plug SDRAM/DRAM module into each DIMM sockets (as a
bank) or two sockets at one time.
CAUTION:
It‘s not recommended to install the 3.3V SDRAM and
5V EDO or Fast Paged mode memory within a system. The 72-pin
DRAM cannot work with 168-pin DRAM in the same time.
Changing EDO/FPM DRAM to SDRAM, you don‘t have to adjust
jumper setting or BIOS value, nor change SDRAM to EDO/FPM
DRAM.
(
※
Please make sure the SDRAM plugged-in fully, to prevent contact
loss.)
