Computer Memory Solutions 4GB (2x2GB) DDR2 667 PC2-5300 CL5 240-pin DIMM memory upgrade

DDR2 667 kit for Asus P5GC-MX boards

This 4 GB kit contains two 2 GB DDR2 667 DIMMs built for the Asus P5GC-MX 1333 and P5GC-MX GBL motherboards. It uses unbuffered, non-ECC modules rated at CL5 5-5-5 timing and 1.8 V. The kit targets owners of those specific boards who need to reach the platform's 4 GB maximum. It is not suited for systems that require ECC, registered memory or a different DDR generation.

DDR2 667 speed ceiling and density limits

The DDR2 667 interface caps transfer rates at the PC2-5300 level, so bandwidth cannot exceed that standard. Each DIMM carries 2 GB in a 2Rx8 organisation, and the board provides only two sockets, fixing the absolute ceiling at 4 GB. Buyers who want more storage or faster memory than DDR2 667 provides cannot use this kit to overcome those limits.

Straightforward two-slot installation

Installation consists of seating both 240-pin modules into the board's two DIMM slots until the retention clips engage. The usual mistake is inserting only one stick and leaving the second slot empty, which halves the capacity. Another common error is forcing a module in the wrong orientation, which can damage the slot or the DIMM's edge connector.
