Dual-Channel DDR2 Kit

This 4 GB kit contains two 2 GB DDR2 DIMMs rated for 800 MHz operation at the standard 1.8 V. It is intended for desktop computers that accept 240-pin unbuffered, non-ECC modules in a dual-channel configuration.

Compatibility Profile

The kit suits owners of older AMD or Intel desktop platforms that specifically require DDR2 800 memory and have two available DIMM slots. Systems that demand ECC or registered modules, or that only support a different DDR generation, cannot use this memory.

Deciding Specification

The critical figure is the 800 MHz DDR2 speed (PC2-6400) combined with 1.8 V unbuffered, non-ECC 240-pin DIMMs; the motherboard must match all of these parameters for the kit to function.

Questions about this item

Will these modules fit a motherboard that only has 184-pin DDR slots?

No. These are 240-pin DDR2 DIMMs and will not seat in 184-pin DDR sockets.

My board specifies 1.8 V DDR2 800 non-ECC memory — is this kit a match?

Yes. The kit runs at 1.8 V, 800 MHz, non-ECC and unbuffered, matching those requirements.

Can I install a single 2 GB stick from this kit if my system has only one free slot?

Yes. Each module is a standalone 2 GB DIMM, so you can populate one slot and add the second later.
