512MB DDR 266 Desktop Module

This Kingston ValueRAM module provides 512MB of DDR memory rated at 266MHz, corresponding to the PC2100 standard with a CAS latency of CL2 and a 2.50V operating voltage. It is designed for desktop systems that accept single-sided DDR DIMMs.

Older PC Maintenance and Capacity Limits

The module suits owners of legacy desktops that require DDR 266 memory to extend usable life or replace a failed stick. It does not suit builds needing more than 512MB per slot, modules with heat spreaders, or systems that demand different voltage or latency specifications.

PC2100 Bandwidth and CL2 Timing

The single specification that decides fit is the PC2100 rating, which delivers up to 2.1GB/s memory bandwidth at CL2 timing. If the motherboard manual lists PC2100 DDR 266 at 2.50V as supported, this module will match that requirement.

Questions about this item

How much bandwidth does the DDR 266 module provide for sustained workloads?

The module delivers up to 2.1 GB/s of memory bandwidth, which is the practical limit for continuous data throughput on this PC2100 part.

Does the memory run hot or loud when the system is under load all day?

With no heat spreader and a standard 2.50 V operating voltage, the stick relies on case airflow; it produces no noise and runs at typical DDR temperatures for its class.

What motherboard slot must already be present for this 512 MB stick to work?

A desktop DDR DIMM socket keyed for 184-pin modules is required; the board must accept PC2100 memory at CL2 timing.
