A-Tech Supermicro Certified 4GB DDR3 1333MHz 1Rx4 ECC RDIMM 240-Pin Server Memory

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.
