HP-Compatible DDR3L ECC RDIMM

This A-Tech 4 GB DDR3L 1600 ECC registered DIMM targets administrators upgrading HP ProLiant servers that require part numbers 713981-B21, 713981-S21, 713754-071, 715282-001 or A2Z49AA. It is a single 1Rx4 module using major-brand chips on a 240-pin form factor. Systems needing unbuffered memory, non-ECC operation or higher-density modules cannot use this stick.

Low-Voltage 1.35 V Operation

Running at 1.35 V, the module draws less power and generates less heat than standard 1.5 V DDR3, helping dense server chassis stay within thermal limits. CL11 latency at 1600 MHz delivers predictable throughput for virtualization and database workloads. Registered buffering reduces electrical load on the memory controller, aiding stability in multi-DIMM configurations.

Lifetime Warranty and US-Based Support

A-Tech backs every module with a lifetime warranty and provides complimentary United States technical support before, during and after purchase. Each stick undergoes quality-assurance testing to verify reliable operation in qualified HP platforms. No additional software, heatsinks or accessories are bundled with the memory.

Questions about this item

How do I install this 240-pin DDR3L RDIMM and what step is often missed?

Align the notch on the module with the slot key, press firmly until both side clips click shut, then verify in BIOS that the 1Rx4 registered module is detected at 1600 MHz.

What maintenance or replacement will this ECC RDIMM need over time?

No routine maintenance is required; the module either continues operating or is replaced if ECC logs reveal uncorrectable errors.

What limit appears first when this 1.35 V CL11 module runs sustained workloads?

The registered buffer and 1.35 V operation cap sustained throughput at the rated 1600 MT/s before thermal or voltage headroom becomes a factor.
