Replacement for HP server DIMMs

This A-Tech module is an 8 GB DDR3L 1600 MHz registered ECC DIMM built to replace HP part numbers 713984-B21, 713983-B21, A2Z51AA, 715283-001, 713983-B211 and 713755-071. It runs at 1.35 V with CL11 latency and a 2Rx4 organisation. The 240-pin form factor fits compatible HP server and workstation platforms.

Suited for registered ECC platforms

It suits administrators upgrading or repairing HP servers that require registered ECC memory at DDR3L 1600 speeds. It is not for systems that accept only unbuffered non-ECC DIMMs, nor for platforms that cannot operate at 1.35 V. Buyers who need a different capacity or rank configuration should verify their motherboard documentation before ordering.

Registered ECC with 2Rx4 layout

The single specification that decides fitment is the registered ECC design with a 2Rx4 rank structure at DDR3L 1600. Only motherboards that explicitly support registered ECC modules in this rank arrangement will POST correctly with this DIMM.

Questions sur cet article

Does my server need a DDR3L 240-pin RDIMM slot to accept this 8 GB module?

Yes, this module is a 240-pin DDR3L ECC registered DIMM, so the motherboard must provide a matching DDR3L RDIMM socket.

Can I mix this 1.35 V CL11 2Rx4 stick with existing 1.5 V DDR3 RDIMMs in the same channel?

Mixing voltages is not recommended; the system will typically default to the higher voltage and may disable ECC or registered operation.

How can I confirm the module is running at 1600 MHz with ECC active after installation?

Check the BIOS memory information or run a tool such as dmidecode to verify speed, voltage, rank and ECC status.
