Supermicro Certified 4GB DDR3 Module

This Supermicro certified 4GB DDR3 module uses Samsung chips and registered ECC circuitry for server reliability. It runs at 1333MHz with CL9 latency at standard 1.50V voltage. The single-rank 1Rx4 organisation suits compatible Supermicro platforms.

240-Pin RDIMM Installation Notes

The 240-pin RDIMM form factor fits keyed DDR3 server slots in one orientation only. Registered buffering adds a clock cycle, so the memory controller must support registered DIMMs. Mixing registered and unbuffered modules will prevent the system from booting.

Sustained Load Behaviour

ECC circuitry corrects single-bit errors during continuous operation without halting the system. Registered signalling reduces electrical load on the memory bus when multiple modules are populated. Standard 1.50V operation keeps power draw predictable under extended workloads.

Questions about this item

How can I confirm the module is running at 1333 MHz with CL9 latency after installation?

Check the memory speed and timings in your server BIOS or a tool such as CPU-Z; they should report DDR3 1333 (PC3-10600) at CL9.

What comes in the package and do I need anything else to install it?

The box contains one 4 GB DDR3 1333 MHz ECC Registered 240-pin RDIMM; no extra parts are required if your system has a free DDR3 RDIMM slot.

Should I choose the 1Rx4 4 GB version or a different capacity for my Supermicro server?

Select this 4 GB 1Rx4 module when your board calls for a single-rank DDR3 1333 ECC RDIMM; match the total capacity to the number of slots you plan to populate.
