SuperMicro DDR4 2133 ECC RDIMM 8GB

This registered DDR4 module delivers 8 GB of error-correcting memory at 2133 MT/s with CL15 latency and 1.20 V operation. It targets administrators upgrading SuperMicro servers or workstations that require registered ECC DIMMs for data integrity.

288-pin registered DIMM for server boards

The 288-pin RDIMM fits DDR4 server motherboards that support registered memory and a 1Rx4 rank configuration. ECC and registered buffering reduce electrical load on the memory controller, freeing slots for additional modules in multi-channel populations.

Samsung Micron Hynix chips tested under load

Major OEM DRAM from Samsung, Micron or Hynix is stress-tested at rated speed before shipment. The validated component mix aims to eliminate early-life failures in mission-critical deployments.

Questions about this item

Will the CL15 latency hold up during sustained server workloads?

The module runs at DDR4 2133 with CL15 timing, so latency stays at the rated value as long as the system operates within spec.

Does the registered ECC design run hotter or draw more power than unbuffered sticks?

Registered ECC DIMMs add a small register load, but at 1.2 V the power draw and heat remain comparable to standard DDR4 modules.

My Supermicro board uses 288-pin DDR4 slots — is that the only requirement?

Yes, the 288-pin DDR4 RDIMM form factor matches the slot; the board must also support registered ECC memory.
