Speed DDR2 667 (PC2 5300)

  • 2GB dual-channel kit doubles memory bandwidth for smoother multitasking
  • DDR2 667 MHz speed accelerates application loading and system responsiveness
  • 8 V standard voltage reduces power draw and heat output
  • 240-pin DIMM form factor fits a wide range of desktop motherboards
  • Non-ECC unbuffered design ensures broad compatibility with consumer desktop PCs

Kit Purpose

This A-Tech kit supplies two 1GB DDR2 modules for desktop systems that accept 240-pin unbuffered memory. The dual-channel pair targets owners of older AMD or Intel platforms needing a straightforward capacity increase.

Build And Connections

Each stick uses the standard 1.8V DDR2 voltage and a 240-pin DIMM edge connector that fits legacy desktop slots without adapters. Unbuffered non-ECC layout means the modules install like ordinary consumer RAM and require no special motherboard support.

Deciding Specification

The rated speed is DDR2 667MHz, also labelled PC2-5300, with a tested CAS latency of CL5. If your board specifies this exact frequency and voltage, the kit will operate at its advertised timing; otherwise the system will fall back to a lower supported speed.

Questions about this item

What speed does the DDR2 667MHz DIMM run at in practice?

The kit operates at 667 MHz, which is the PC2-5300 standard for DDR2 DIMM memory.

What physical slot does this 240-pin DIMM require?

It fits a standard 240-pin DDR2 DIMM socket on a desktop motherboard.

How do I install the dual-channel kit and what step is often missed?

Insert both 1GB modules into matching-colour slots for dual-channel mode; the step often missed is pressing each module down until the retention clips click on both sides.
