2GB DDR2-800 Desktop DIMM

This SK hynix module provides 2GB of DDR2 memory rated at PC2-6400 and 800 MT/s. It uses a standard 240-pin DIMM form factor and is built as a 2Rx8 unbuffered, non-ECC stick. The part is suited for upgrading or repairing older desktop platforms that accept this generation of memory.

Ideal for legacy desktop upgrades

Builders restoring or maintaining systems that take DDR2 DIMMs will find this module a direct match. It is not suitable for anyone needing ECC error correction or registered buffering. Buyers whose boards require a newer memory generation or a different pin count must look elsewhere.

240-pin DDR2 interface decides fit

The single specification that determines compatibility is the 240-pin DDR2 interface running at PC2-6400 speed. Only motherboards designed for this exact pin layout and signalling standard can accept the module. Verify the board manual before purchase.

商品問答

What motherboard slot does the 240-pin DDR2 DIMM require?

The module fits a standard 240-pin DDR2 DIMM socket on a desktop motherboard that supports PC2-6400 memory.

Can I add this 2Rx8 PC2-6400U-666-12 stick next to older DDR2 modules running at lower speeds?

Yes, the memory will down-clock to match the slowest installed module while keeping the same 240-pin DDR2 interface.

How do I confirm the module is running at DDR2-800 after installation?

Check the BIOS memory information or a system utility such as CPU-Z; it should report 800 MT/s and PC2-6400 bandwidth.
