CAUTION! Memory is static sensitive. Do not handle loose memory modules without grounding yourself or using an anti-static strap. Failure to do so can result in damage to the modules, and result in premature failure or intermittent problems. Most systems have power saving features and should have the power cable disconnected before installing or removing memory, CPUs, or adapter cards.

Description:
The GA-6WMMC7 system board has two 168-pin DIMM sockets to support up to 1.0GB unbuffered 3.3 volt SDRAM DIMMs. Only PC100 SDRAM DIMMs are documented in the specifications. PC133 should work, but no additional performance would be gained. We do not recommend mixing memory speeds in the system. Instead use all PC-100 or all PC-133 to avoid problems. Memory may be installed one DIMM module at a time.

Gigabyte GA6WMMC7 System Board Layout
There are two 168-pin SDRAM DIMM slots on the GA-6VX7 system board. PC-100 SDRAM is supported in 16, 32, 64, 128, 256, and 512MB size DIMMs.

SDRAM DIMM Description
The SDRAM DIMM has two notches along the bottom of the module.

Installation
To install the SDRAM DIMM into an available memory slot, push the plastic tabs away from the available slot. Insert the module vertically, and press down until it snaps into place. Be sure to align the notches and raised areas of the slot. The side tabs should move to the locked position as the module snaps into the socket.

To install memory modules, follow these steps:

1. Insert each DIMM module vertically into its slot. Pay attention to the two notches along the bottom of the module to prevent inserting the DIMM incorrectly.
2. Gently press down on the DIMM module until it snaps into place.
3. If installing only a single DIMM, fill bank 0 first. The GA-6WMMC7 will support a total of 1.0GB of unbuffered 3.3V SDRAM in its two DIMM slots.

Configurations
Some typical configurations are listed below. All modules must be either PC-100 or PC133 SDRAM DIMMs:
