512MB DDR2 667 module

This Crucial Ballistix stick delivers 512MB of DDR2 667 memory rated at PC2 5300 with CL3 3-3-3-12 timings. It is built for enthusiasts and gamers running legacy desktop platforms that require DDR2 technology. The integrated aluminium heat spreader helps manage the 2.20V operating voltage during sustained loads.

240-pin desktop installation

The module uses the standard 240-pin DDR2 form factor and drops into any motherboard slot wired for DDR2 667 operation. No extra cables or brackets are needed, and the low-profile spreader leaves room for larger CPU coolers or tight case layouts. Pair multiple sticks to reach the capacity your board supports.

Thermals and power at 2.20V

At the rated 2.20V the spreader keeps chip temperatures in check without active airflow directly on the modules. Power draw stays modest for a single 512MB stick, so standard case ventilation is usually sufficient. The fixed CL3 timings mean no extra voltage is required for stability in everyday gaming or multitasking sessions.
