A-Tech Supermicro Certified MEM-DR480L-SL01-ER21 8GB DDR4 2133 ECC RDIMM

Supermicro Certified 8GB DDR4 ECC RDIMM

This module delivers eight gigabytes of registered DDR4 memory at 2133 MT/s with CL15 latency and 1.2 V operation. It is built for servers and workstations that require error-correcting code protection and registered signal integrity. The single-rank 1Rx4 organisation uses Samsung components validated under the Supermicro MEM-DR480L-SL01-ER21 qualification. It targets administrators upgrading or populating Supermicro platforms that specify PC4-17000 registered DIMMs.

Sustained-load behaviour with registered ECC

Registered buffering reduces electrical load on the memory controller, allowing stable operation when all slots are populated under continuous multi-threaded workloads. ECC corrects single-bit errors and detects multi-bit errors without halting the system, preserving data integrity during long compute runs. The 1.2 V standard voltage keeps power draw predictable across extended duty cycles. CL15 timing at 2133 MT/s provides consistent latency for memory-bound server applications.

Upgrade from non-ECC or lower-capacity RDIMMs

This DIMM replaces unbuffered non-ECC modules in systems that mandate registered memory with error correction. It also supersedes smaller-capacity registered DIMMs when the platform supports 8 GB per slot and the qualified part list includes the MEM-DR480L-SL01-ER21 designation. The jump is worthwhile when workloads demand registered signalling, ECC protection, or higher per-slot density than the currently installed modules provide.
