Capacity and Speed

This module delivers 4GB of DDR2 memory operating at 800MHz with a PC2-6400 rating. It uses the standard 1.8V voltage and a 240-pin DIMM form factor for desktop systems. The CL6 latency provides responsive performance for compatible platforms.

Target Audience

This upgrade suits owners of older desktop PCs that require DDR2 800MHz unbuffered non-ECC memory. It is not suitable for systems that need registered or ECC modules, nor for platforms that use a different memory generation.

Deciding Specification

The 240-pin DDR2 interface is the single specification that determines whether this module will fit and function in your motherboard. Verify that your system specifically supports DDR2 800MHz PC2-6400 unbuffered DIMMs before purchasing.

商品問答

Will this module fit a motherboard that only accepts DDR2 memory?

Yes, this is a DDR2 DIMM with 240 pins and runs at 1.8 V, so it fits standard DDR2 desktop slots.

My board lists PC2-6400 as the maximum supported speed — is this module compatible?

The module is rated PC2-6400 at 800 MHz and will operate at that speed or downclock if the board requires a lower frequency.

Does this 4 GB stick require ECC or registered memory support?

No, it is a non-ECC unbuffered UDIMM, which is the common type used in most consumer desktop motherboards.
