Server DDR2 ECC Memory Kit

This 8 GB kit consists of four 2 GB DDR2 fully buffered DIMMs rated at 667 MHz with CL5 timings. It is built for servers and workstations that require registered ECC memory in a 240-pin form factor. The modules operate at 1.8 V and use a 2Rx4 organisation. Buyers needing unbuffered desktop DDR2 or higher capacities per module should look elsewhere.

Thermals and Power in Normal Use

Each module runs at the standard 1.8 V DDR2 voltage, keeping power draw modest for fully buffered designs. No heat spreaders are included unless current inventory specifies them, so airflow across the sticks is the primary cooling method. Fan noise will depend entirely on the server chassis and its fan curves. Systems without adequate front-to-back airflow may see higher temperatures under sustained load.

Build Quality and Daily Implications

The 240-pin fully buffered DIMM keying prevents accidental installation in standard desktop slots, ensuring the kit only fits compatible server boards. Four modules must populate the correct channels for full capacity and error-correcting function. The kit is covered by the manufacturer's limited lifetime warranty when purchased directly, and the genuine major-brand chipset supports long-term reliability in 24/7 environments.

Questions about this item

How do I install these 240-pin FB-DIMM modules in a PC5300 server, and which step is most often missed?

Power down the server, open the chassis, align each module's notch with the slot key, press firmly until both ejector clips click, then populate all four channels in the order the service manual specifies — skipping the channel sequence is the step most often missed.

What maintenance or replacement will this 8GB DDR2 ECC kit need later?

DDR2 FB-DIMM modules have no moving parts or batteries; the only later action is replacement if a module fails or if the server is upgraded to a platform that no longer supports DDR2 technology.

What limit appears first when these CL5 1.8V modules run under sustained load?

The DDR2-667 bus speed and CL5 latency set the throughput ceiling; under sustained use the memory controller reaches its maximum bandwidth before thermal or voltage limits become a factor.
