4GB DDR3L 1333 ECC RDIMM

This 4 GB DDR3L registered DIMM runs at 1333 MHz with CL9 latency and 1.35 V operation. It uses a 1Rx4 organisation and major-brand chips on a 240-pin module. The stick is designed for server and workstation platforms that require ECC error correction and registered signalling.

Suited for IBM-Lenovo part-number matches

The module replaces IBM-Lenovo part numbers 00U0283, 03X3815, 0A89415, 46C0563, 47J0145, 49Y1388, 49Y1406, 49Y1424 and 90Y4551. Buyers needing unbuffered UDIMMs, higher frequencies or larger single-module capacities should look elsewhere.

Handles light virtualisation and legacy workloads

Four gigabytes provides enough headroom for basic hypervisor hosts, file services or older database instances. Capacity runs out quickly with modern container densities, heavy virtualisation or in-memory analytics that demand 8 GB or more per slot.

Questions about this item

What motherboard slot does the 240-pin DDR3L RDIMM need?

It fits a standard DDR3 DIMM slot that accepts 1.35 V registered modules; the board must support ECC RDIMM at 1333 MHz.

Can I mix this 1Rx4 ECC registered stick with older unbuffered DDR3 DIMMs?

No — registered and unbuffered DIMMs cannot share a channel; all slots in that channel must use registered ECC modules.

How do I confirm the module runs at 1333 MHz CL9 after install?

Check the BIOS memory information or a tool like CPU-Z; it should show 1333 MT/s, CL9 timings and 1.35 V.
