Kingston Technology Corp. KVR667D2D8P5/1G 1GB DDR2 667 ECC Registered server RAM

1 GB DDR2 667 ECC Registered module

This 1 GB DDR2 667 (PC2 5300) module is built for servers and workstations that require registered ECC memory. It fits 240-pin DIMM slots and operates at a standard 1.80 V with CL5 latency. The registered buffer helps maintain signal integrity on heavily populated motherboards. It is not suited for consumer desktops or laptops that use unbuffered non-ECC memory.

Thermals and power in normal use

Without a heat spreader the module relies on case airflow for cooling, which is typical for registered DDR2 server DIMMs. Power draw stays low at the standard 1.80 V, so additional cooling is rarely needed in a properly ventilated chassis. Acoustic impact is negligible because the component has no moving parts. Servers with restricted airflow should still verify adequate circulation around the memory slots.

Build integration and trade-offs

The 240-pin form factor requires a motherboard with DDR2 registered DIMM slots and chipset support for ECC. Each stick adds 1 GB of capacity, so larger memory configurations need multiple free slots. The registered design limits compatibility to platforms that explicitly support buffered memory. Builders needing higher densities or faster speeds must select different modules.
