1GB DDR2 667 Module for Lenovo Desktops

This 1GB 240-pin DDR2 SDRAM module runs at 667 MHz (PC2-5300) with CL5 latency and 1.80V operation. It is an unbuffered, non-ECC stick validated for specific Lenovo ThinkCentre A52 and M52 models. The part matches OEM FRU numbers 30R5126 and 41X4256.

Thermals, Noise and Power Draw

Low-voltage DDR2 technology keeps power consumption modest during typical office workloads. No heat spreader is fitted, so the module relies on chassis airflow for cooling. Solid-state construction means zero acoustic output under normal use.

Behaviour Under Sustained Load

Extended sessions maintain stable CL5 timings at the rated 667 MHz frequency. The unbuffered design introduces no additional latency overhead during continuous data throughput. RoHS and WEEE compliance confirms the components meet environmental standards for long-term operation.

Questions about this item

How do I install the 240-pin DDR2 module in my ThinkCentre A52 8153 and what step is often missed?

Power off, open the case, align the notch on the module with the slot key, press firmly until both retention clips snap shut, then power on and verify 667 MHz in BIOS; the step often missed is seating both ends evenly so both clips engage.

What maintenance or replacement will the KTM4982/1G need over its lifetime?

No scheduled maintenance is required; keep interior dust-free and ensure airflow. Replacement is only needed if a memory test reports errors or the system fails to POST with the module installed.

What limit appears first when the 1 GB DDR2 667 module runs under sustained load?

The 1 GB capacity ceiling is reached before thermal or bandwidth limits; once the operating system exhausts the single module, paging to disk becomes the bottleneck.
