Axiom 32 GB DDR3 1333 ECC Buffered module

This 32 GB registered DDR3 LRDIMM runs at 1333 MHz with CL9 latency and a low 1.35 V operating voltage. Error-correcting code and buffered signal processing protect data integrity in multi-socket servers. The single 240-pin module fits standard DDR3 LRDIMM slots. RoHS compliance confirms restricted-substance adherence.

Suited for DDR3 servers needing maximum density

Ideal for administrators expanding memory capacity in compatible DDR3 platforms that support registered LRDIMMs and ECC. Not suited for systems that accept only unbuffered UDIMMs, for boards limited to lower densities per DIMM, or for platforms requiring a different DDR generation. The 1.35 V specification also excludes boards fixed at 1.5 V only.

32 GB per LRDIMM at DDR3 1333 MHz

The single-module 32 GB capacity at 1333 MHz is the decisive specification; it determines whether the board's memory controller and BIOS support this density and speed combination. Verify that the server qualification list approves 32 GB LRDIMMs at PC3 10600 before purchase.

Questions about this item

How do I confirm the 32GB DDR3 1333 ECC Buffered module is running at 1333 MHz with CL9 latency after installation?

Enter the server BIOS or UEFI and check the memory information screen; it should show 32GB size, 1333 MHz speed, DDR3-1333/PC3-10600 standard, ECC enabled and CAS latency CL9 for the installed module.

What is included with the 647903-B21-AX module and what extra items are required for installation?

The box contains one 32GB 240-pin LRDIMM DDR3 module rated at 1.35 V; no cables, brackets or additional parts are supplied, and no separate components are needed beyond a compatible 240-pin DDR3 server memory slot.

Which capacity and speed version of this Axiom LRDIMM should I choose for a system that requires PC3-10600 registered ECC memory?

Select the 32GB DDR3 1333 (PC3-10600) ECC Buffered LRDIMM — it matches the exact capacity, speed grade, voltage, pin count and form factor specified for that requirement.
