Server DDR2 ECC Module

This 1 GB Kingston module uses 240-pin DDR2 SDRAM running at 667 MT/s with CL5 latency and 1.80 V operation. It is built as a single-rank, fully buffered stick with ECC for data integrity in server workloads.

Thermals and Power

The module operates at the standard 1.80 V for DDR2, drawing modest power typical for this generation. Fully buffered architecture adds an advanced memory buffer chip that manages signal integrity, contributing slightly more heat than unbuffered equivalents. Passive cooling via system airflow is sufficient; no active cooling is required.

Intel Compatibility Tested

The Intel Compatibility Tested badge means the module has passed validation on Intel server platforms, reducing the risk of POST failures or timing mismatches. Buyers who need larger capacities or higher speeds must select different modules, as this stick is fixed at 1 GB and 667 MT/s.

Questions about this item

How do I install this 240-pin DDR2 module and what step is often missed?

Align the notch on the 240-pin DDR2 stick with the slot key, press down firmly until both side clips snap shut, and verify the system detects the full 1GB at DDR2 667 speed.

What maintenance or replacement will this ECC fully buffered memory need later?

No routine maintenance is required; replace the module only if memory diagnostics report uncorrectable ECC errors or the system fails to POST with it installed.

What limit appears first when this CL5 1.80V module runs under sustained load?

The DDR2 667 bandwidth ceiling is reached before thermal throttling, so sustained throughput tops out at the rated 667 MT/s data rate.
