Install The Memory Modules - PCchips MB694A Manual

Install the Memory Modules

For this mainboard, you must use 168-pin 3.3V non-buffered
Dual In-line Memory Modules (DIMMs). The memory chips must
be standard or registered SDRAM and VCM SDRAM memory
chips. The memory bus can run at 66 MHz, 100 MHz or 133
MHz. If your processor operates over a 133 MHz system bus,
you can install PC133 or PC100 memory that operates over a
133 or 100 MHz bus. If your processor operates over a 100 MHz
system bus, you can install memory that operates over a
133MHz, 100 MHz or 66MHz bus. If your processor operates
over a 66MHz, you can only install memory chips that operate at
66MHz or 100MHz.
Supported Memory Configurations
The following table shows the memory configurations supported:
Technology Configuration
64 Mbit 8M x 8
64 Mbit 4M x 16
128 Mbit 32M x 4
128 Mbit 16M x 8
Note: 32M x 4 128 Mbit is for registered DIMMs only, 4M x 16 64 Mbit sup-
port is for unbuffered DIMMs only.
