Install The Memory Modules - ECS K7VZA 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 regist ered SDRAM (Synchronous Dynamic
Random Access Memory).
The memory bus can run at 100 MHz or 133 MHz. If your
processor operates over a 100 MHz system bus, you can install
PC100 or PC133 memory modules that operate over a 100 MHz
or 133 MHz memory bus. If your processor operates over a 133
MHz system bus, you can only install PC133 memory modules
that operate over a 133 MHz memory bus.
