A-Tech 4GB DDR3L 1333 ECC RDIMM

This 4GB DDR3L registered DIMM runs at 1333MHz with a low 1.35V voltage and CL9 latency. It uses a 2Rx4 organisation and major-brand chips on a 240-pin form factor. The module is built as a direct replacement for IBM-Lenovo part numbers 46C0567, 47J0133, 49Y1394 and 49Y1412. It targets server and workstation administrators who need validated ECC memory for supported platforms.

Suited for ECC registered DDR3L slots only

This module fits systems that specifically require DDR3L registered ECC memory at 1333MHz. It is not for desktops or laptops that accept only unbuffered non-ECC UDIMMs. It will not work in platforms limited to 1.5V DDR3 or those that cannot address registered modules. Buyers needing higher capacity per slot or a different voltage should verify their hardware documentation before ordering.

Registered ECC with 2Rx4 organisation

The defining specification is the registered ECC design combined with a 2Rx4 rank structure at 1.35V. This combination determines whether the memory will initialise in your server's memory controller. Match the part numbers listed — 46C0567, 47J0133, 49Y1394, 49Y1412 — against your system's qualified vendor list to confirm compatibility.

Questions about this item

Does the DDR3L 1333 PC3L-10600 interface cap memory speed at 1333 MHz?

Yes, the module is rated at DDR3L 1333 (PC3L-10600) so the maximum data rate is 1333 MT/s when installed in a compatible server.

What physical slot does the 240-pin RDIMM need to fit?

It requires a standard DDR3 240-pin DIMM socket on the server motherboard; the registered design will not work in unbuffered desktop slots.

How is the ECC RDIMM installed, and what step is often missed?

Power down the server, open the chassis, align the notch on the 240-pin module with the key in the slot, press firmly until both retention clips click, then verify in BIOS that ECC and registered mode are enabled.
