What this module is

This A-Tech 4GB DDR3L 1600 ECC RDIMM is a registered server memory module built for IBM-Lenovo systems using part number 47J0219. It runs at 1.35V low voltage with CL11 latency and a 1Rx4 organisation on a 240-pin DIMM.

Who it suits and who should look elsewhere

It suits administrators upgrading compatible IBM-Lenovo servers or workstations that require registered ECC DDR3L memory at this exact density and speed. Buyers whose platforms demand unbuffered DIMMs, a different voltage, higher capacity per module, or a newer DDR generation should look elsewhere.

Behaviour under sustained load

The registered buffer and on-die ECC maintain signal integrity and correct single-bit errors continuously during prolonged workloads. Low-voltage operation at 1.35V reduces thermal output compared to standard DDR3, helping stability when all slots are populated for extended periods.

Questions about this item

What server motherboard slot does this 240-pin DDR3L RDIMM require?

This module fits a 240-pin DDR3 DIMM slot that supports registered ECC memory at 1.35 V.

Can I mix this 1Rx4 CL11 1.35 V stick with existing 1.5 V DDR3 RDIMMs in the same system?

All installed DDR3 modules must run at the lowest common voltage; the system will operate the 1.35 V stick at 1.5 V if the memory controller does not support DDR3L.

How do I confirm the module is recognised as 4 GB ECC registered at 1600 MHz after installation?

Check the BIOS memory information or run a system utility such as dmidecode to verify capacity, ECC type, registered status and 1600 MT/s speed.
