1GB DDR2 667 Desktop Module

This 1GB DDR2 667 (PC2 5300) unbuffered DIMM runs at 1.80V with CL5 latency. It is a single CT12864AA667 stick built for older desktop platforms that accept DDR2 memory. The module has no heat spreader and no ECC function. It suits repairs or upgrades on legacy boards that specifically require this speed and voltage.

Who it suits and who it does not

It fits owners of desktops with DDR2 slots that support 667 MT/s operation at 1.80V. It is not for systems that need ECC or registered memory, nor for builds that require more than 1GB per slot. Buyers whose motherboard calls for a different voltage or a higher DDR2 speed should look elsewhere.

Deciding specification: DDR2 667 (PC2 5300)

The module operates at the DDR2 667 (PC2 5300) data rate with 1.80V supply and CL5 timing. That speed grade is the single figure that determines whether the stick will be accepted by the board. Match this rating exactly to the motherboard specification before purchase.

商品問答

Does the CT12864AA667 module arrive alone or with extra parts such as a heat spreader?

The 1 GB DDR2 667 stick is supplied as a single unbuffered module without a heat spreader; no additional components are included in the package.

How do I decide between the PC2 5300 rating and a faster DDR2 speed if my board supports both?

Choose this PC2 5300 module when your motherboard specifies DDR2 667 or lower; it will run at 667 MT/s with CL5 timing at 1.80 V.

What does the 667 MT/s headline speed mean once the memory is installed in a desktop?

The module transfers data at 667 million transfers per second at CL5 latency, delivering the standard PC2 5300 bandwidth for DDR2 systems.
