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.

商品問答

What does the 800MHz rating mean once this module is installed in a desktop?

The 800MHz rating indicates the module runs at 800 million cycles per second, delivering a peak bandwidth of 6400 MB/s when the memory controller operates at that speed.

How does the PC2-6400 standard limit real-world throughput on a 240-pin DDR2 system?

PC2-6400 caps the theoretical maximum transfer rate at 6400 MB/s; actual throughput will be lower due to latency, controller efficiency and other system overheads.
