Supermicro Certified 4GB DDR3L RDIMM

This 4GB DDR3L module runs at 1333MHz with CL9 latency and a 1.35V operating voltage. It uses a 2Rx8 registered ECC design on a 240-pin form factor. The Micron chipset is validated for Supermicro server platforms requiring registered memory.

DDR3L 1333 registered ECC constraints

Registered DIMMs add a clock cycle of buffering that unbuffered consumer boards cannot accept. The 1.35V low-voltage spec also prevents use in systems that only support standard 1.5V DDR3 slots. Mixing registered and unbuffered modules on the same channel will prevent the system from posting.

4GB capacity for light server workloads

A single 4GB stick suits entry-level virtualisation hosts or file servers with modest memory demands. Larger databases or heavy virtualisation clusters will exhaust this capacity quickly, requiring higher-density modules or additional populated slots to maintain performance headroom.

Questions about this item

Should I choose the 4GB DDR3L 1333MHz module or a different capacity?

This listing is for a single 4GB DDR3L 1333MHz registered ECC module; select it when your server requires low-voltage DDR3 RDIMMs in that exact density.

What does the 1333MHz speed deliver in a live server?

The module runs at 1333MHz with CL9 latency at 1.35V, providing the rated PC3L-10600 bandwidth for the memory controller it is installed in.

How does the 240-pin RDIMM interface limit use?

The 240-pin registered ECC DIMM fits only DDR3 RDIMM slots that support registered modules; it cannot be used in unbuffered UDIMM sockets.
