HP 261586-051 2GB DDR266 ECC Registered DIMM

This HP 261586-051 module provides 2GB of DDR266 ECC registered memory for HP ProLiant servers. It operates at 266 MHz with a CAS latency of CL2.5 and requires 2.50 V. The 184-pin DIMM form factor fits compatible server motherboards designed for registered modules.

Capacity and headroom for legacy server workloads

A single 2GB stick adds modest capacity to systems using the DDR266/PC2100 standard. It handles older operating systems and light database tasks within that limit. Headroom runs out quickly with modern virtualisation or multi-user loads that demand larger memory pools per channel.

Build quality and daily implications

The 1.2-inch width and 184-pin layout match the registered DIMM slot keying on supported HP ProLiant platforms. ECC and registered signal processing improve data integrity for continuous operation. Installers must verify the motherboard accepts registered DDR SDRAM before seating the module.

Questions about this item

Will this 184-pin DDR266 registered DIMM work in an older HP ProLiant server that currently uses PC2100 memory?

Yes, the module matches the DDR266/PC2100 standard, runs at 266 MHz with CL2.5 latency and uses the 184-pin DIMM form factor required by those systems.

How can I confirm the 2GB module is detected and running with ECC after installation?

Check the BIOS memory summary or POST screen; it should show 2 GB at 266 MHz with ECC enabled and registered signal processing active.

Does the 261586-051 come as a single 2GB stick or do I need to order additional modules separately?

The package contains one 2 GB registered DIMM; any extra modules must be purchased separately.
