  • DDR2 667 speed matches PC2 5300 platform requirements
  • Heat spreader aids thermal management during sustained operation

Capacity and Server Fit

This 2 GB DDR2 module targets administrators maintaining legacy servers that require fully buffered ECC memory. The dual-rank design delivers registered error correction for data integrity in multi-socket platforms. It is not suited for desktop boards that lack chipset support for fully buffered DIMMs or for systems needing higher density per slot.

Thermals and Power Draw

Operating at 1.80 V with an integrated heat spreader, the module runs cool under typical server workloads. The registered buffer adds minimal latency while stabilising the memory bus across multiple ranks. No active cooling is required beyond standard chassis airflow. Acoustic impact is negligible in rack environments.

Accessories and Software Impact

The heat spreader is the only bundled hardware; it improves thermal headroom without altering slot clearance. No configuration utilities, firmware tools or diagnostic software accompany the kit. Installation is limited to seating the 240-pin DIMM and enabling ECC in the system BIOS.

Questions about this item

How do I install this 240-pin DDR2 module and what step do people often miss?

Align the notch on the gold edge with the key in the slot, press firmly until both retaining clips click shut, and verify the system detects the full 2 GB at 667 MHz; the step often missed is seating the module evenly so both clips engage simultaneously.

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

No routine maintenance is required; if a memory test eventually reports uncorrectable errors the module must be replaced because DDR2 components are no longer produced.

What limit appears first under sustained load on this CL5 1.80 V kit?

The DDR2 667 bandwidth ceiling is reached before thermal throttling, so throughput plateaus at the rated 5300 MT/s transfer rate during prolonged workloads.
