4 GB DDR2-800 desktop module

This module delivers 4 GB of DDR2 memory at 800 MHz with a CL6 latency rating. It uses the standard 240-pin DIMM form factor and operates at 1.50 V. The unbuffered, non-ECC design suits typical desktop motherboards that accept PC2-6400 memory.

Thermals, noise and power draw

DDR2 memory runs passively without fans, so the module adds no audible noise to the system. Power consumption is limited to the 1.50 V supply rail and scales with the 800 MHz data rate. Under normal desktop workloads the thermal output remains low and is handled by ordinary case airflow.

What the bundle changes

The product ships as a single 4 GB stick with no additional brackets, cables or software utilities. Installing it simply increases the system memory capacity by 4 GB on a compatible DDR2 platform. No extra configuration or driver installation is required beyond standard BIOS detection.

Questions about this item

How do I install the 240-pin DDR2 DIMM and which orientation step is most often missed?

Align the single notch on the module with the key in the 240-pin slot, press down evenly until both side clips click shut, and verify the notch is fully seated — the most common mistake is stopping before the clips engage.

What maintenance or replacement will the 4 GB unbuffered DDR2 module need over time?

No scheduled maintenance is required; keep the contacts clean and ensure the motherboard supplies a steady 1.50 V — if errors appear, replace the module rather than attempting repair.

What limit appears first when the CL6 DDR2 800 module runs under sustained load?

The CAS latency of CL6 at 800 MHz sets the timing ceiling; prolonged heavy workloads hit this latency bound before bandwidth or voltage limits become the bottleneck.
