Install The Memory Modules - ECS P6VXM2 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 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 proc-
essor 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.
The following table shows the maximum memory for DIMM
based platforms:
