8 GB DDR2 667 kit for desktop upgrades

This kit contains four 2 GB unbuffered DDR2 667 modules that operate at 1.8 V with CL5 timing. It is intended for owners of older desktop systems that accept 240-pin UDIMMs and need a straightforward capacity increase.

Capacity and headroom: 8 GB total across four slots

The 8 GB total fills four DIMM slots, giving a legacy platform enough memory for everyday multitasking and larger file handling. Systems limited to DDR2 667 will run at that speed, and the CL5 latency is fixed by the JEDEC specification.

JEDEC-standard 1.8 V DDR2 667 specification

The modules conform to the PC2-5300 JEDEC standard, so they install without voltage or timing changes in compatible motherboards. Buyers must verify that their desktop accepts DDR2 667 UDIMMs before purchase, because DDR2 is physically and electrically incompatible with later DDR generations.

Questions about this item

Will this 8 GB kit install in a desktop that uses 240-pin DDR2 slots?

Yes — the kit contains four 2 GB unbuffered DIMMs built to the 240-pin DDR2 667 PC2-5300 CL5 1.8 V JEDEC standard, so any board accepting that specification can use them.

Does the kit require matched pairs for dual-channel operation?

The four modules are sold as a matched set; populating two or four slots on a dual-channel board will run in dual-channel mode automatically.

Is the memory compatible with systems limited to 1.8 V DDR2?

Each module operates at the standard 1.8 V for DDR2 667, matching the voltage requirement of boards designed for that generation.
