Server memory upgrade

This A-Tech module provides 4GB of DDR3 ECC registered memory for compatible HP server and workstation systems. It operates at 1066MHz with a CL7 latency and standard 1.50V voltage. The 240-pin DIMM uses major brand chips and undergoes quality assurance testing for dependable operation.

Registered ECC with 4Rx8 organisation

The module implements registered ECC technology with a 4Rx8 rank configuration, a combination that determines whether the system memory controller can address it. Systems requiring unbuffered or non-ECC DIMMs will not accept this part, and mixing rank organisations can prevent the server from posting.

Fits HP part numbers 500204-061 500660-B21

Installation requires an available 240-pin DDR3 DIMM slot on a platform that supports registered ECC memory at the PC3-8500 speed grade. The single-module design leaves remaining slots free for further capacity expansion within the system's supported limits.

Questions sur cet article

What does the 1066MHz DDR3 speed actually deliver when installed in a server?

The module runs at 1066MHz with CL7 latency and 1.5V, providing the rated PC3-8500 bandwidth for registered ECC workloads in compatible HP systems.

How does the registered ECC RDIMM interface affect what the system can use?

The 240-pin registered DIMM with ECC requires a server chipset that supports registered memory; it will not work in desktop boards that only accept unbuffered modules.

What physical slot and clearance does this 240-pin DIMM need to fit?

It installs in a standard DDR3 240-pin DIMM socket; the registered design adds a buffer chip on the module but uses the same keying and height as other DDR3 RDIMMs.
