Kingston Technology Corp. TCM633-QAC 1GB DDR2 PC2-6400 800MHz desktop RAM

1 GB DDR2 desktop memory module

This Kingston TCM633-QAC stick adds 1 GB of DDR2 memory to a desktop system. It uses the PC2-6400 standard and runs at 800 MHz. The module is non-ECC and single rank. It is suited for older platforms that require DDR2 DIMMs.

240-pin DIMM form factor

The module fits a 240-pin DDR2 DIMM slot, which is the single specification that decides whether this is the correct part. Builders whose motherboards use a different pin count or memory type cannot use this stick. Buyers who need more than 1 GB per slot should look elsewhere.
