HP/Compaq System Memory

This 2 GB DDR2 module is built for HP and Compaq systems that require 240-pin PC 4200 memory with ECC. It delivers 2 GB of registered server-class capacity at DDR 533 speed. The part matches HP manufacturer part number 393354-B21 for direct replacement.

ECC Registered Upgrade

Suitable for owners of compatible HP/Compaq workstations or servers needing to add or replace ECC registered memory. Builders using consumer desktop boards, laptops or any platform that only accepts non-ECC unbuffered DIMMs should look elsewhere.

240-Pin DDR2 533 ECC

The decisive specification is the 240-pin DDR2 SDRAM interface running at DDR 533 (PC 4200) with ECC. Only systems designed for this exact pin count, speed and error-correction type will accept the module.
