Transcend 1GB DDR2 667 Desktop Module

This Transcend JetRam module provides 1GB of DDR2 memory rated at 667 MHz with CL5 timings. It operates at the standard 1.80V for DDR2 platforms and is 100% tested for compatibility. The stick delivers up to 5.3 GB/s bandwidth for older desktop systems.

Ideal for Legacy DDR2 Upgrades

This module suits owners of older desktops that require DDR2 667 (PC2 5300) memory to restore function or add capacity. It is not for builders working with modern platforms that use newer memory generations or higher speeds. Systems needing ECC error correction or larger single-stick capacities must look elsewhere.

Single Specification: DDR2 667 (PC2 5300) Interface

The memory type and speed rating are the only factors that decide fitment. Only motherboards with DDR2 slots keyed for 667 MHz operation will accept this module. Voltage and timing are fixed at 1.80V and CL5, so no BIOS adjustment is required or possible.
