8GB DDR3 1333 ECC Registered DIMM

This Axiom X4911A-AX module provides 8GB of DDR3 memory at 1333MHz with ECC and registered signal processing. It uses a 240-pin DIMM form factor built to the PC3-10600 standard for server environments.

Suits Sun Fire X4170 M2 and X4270 M2 upgrades

This memory fits the listed Sun Fire servers requiring registered ECC DDR3 modules. Builders needing unbuffered memory or a different DDR generation should look elsewhere.

Registered ECC signal processing

The registered buffer reduces electrical load on the memory controller while ECC corrects single-bit errors. Systems that require unbuffered non-ECC modules cannot use this DIMM.
