SKU CH-B5DT-7MG8S

512 MB desktop DDR memory module running at 266 MHz PC2100 with ECC and 184-pin unbuffered design

  • 512 MB capacity supports memory-intensive legacy applications
  • 266 MHz DDR speed matches PC2100 system requirements
  • ECC 64M x 72 architecture detects and corrects data errors
  • 184-pin unbuffered DIMM fits standard desktop slots
  • 5 V CL2.5 timing meets industry-standard specifications

ValueRAM 512 MB DDR ECC module

This Kingston ValueRAM module supplies 512 MB of DDR memory at 266 MHz (PC2100). It is an 184-pin unbuffered DIMM with ECC and a CAS latency of 2.5, built to industry-standard specifications. Each unit is 100-percent tested and ships as a single module rather than a kit.

Suits legacy DDR systems needing ECC

The module fits desktop boards that accept 184-pin DDR DIMMs running at 2.5 V and require error-correcting code memory. It is not suitable for systems that only support non-ECC memory or that use a different pin count or voltage. Buyers who need higher capacity or a matched pair should look elsewhere.

184-pin ECC DDR at 2.5 V decides fit

The decisive specification is the 184-pin ECC DDR interface operating at 2.5 V with a 64M x 72 organisation. If the motherboard calls for that exact combination the module will work; otherwise it will not seat or function correctly.

Questions about this item

Does the 2.5 V operating voltage limit headroom for sustained heavy workloads?

The module is specified at 2.5 V and CL2.5 timing; running at the rated voltage keeps it within the validated envelope for continuous operation.

How much heat or noise does the 184-pin unbuffered ECC DIMM produce during all-day use?

As a passive 184-pin unbuffered DIMM it generates only the normal heat of a 512 MB DDR-266 module and has no fan, so it adds no audible noise.

What motherboard slot and chipset support are required for this 64M×72 ECC stick to function?

It needs a desktop board with an 184-pin DDR socket that accepts 2.5 V unbuffered ECC modules and supports PC2100 speed.
