OWC 8GB DDR3 ECC RDIMM

This 8GB DDR3 1333 registered ECC module is built for Supermicro SuperServer 5086B 8026B and 8046B systems. It delivers 1333 MT/s speed with CL9 latency at 1.5V in a 240-pin 2Rx4 layout. Workstation and server operators who need error-correcting registered memory for these platforms can install a single 8GB upgrade.

Check DDR3 registered ECC slots

Verify that your SuperServer has free 240-pin DDR3 RDIMM slots and that the BIOS supports 1333 MT/s registered ECC modules. This memory cannot be mixed with unbuffered DIMMs and will not fit standard desktop boards. OWC recommends matching capacity speed and manufacturer across all populated slots for best stability.

Sustained server workload behaviour

Registered ECC construction corrects single-bit errors and reduces electrical load on the memory controller during continuous operation. The module runs at 1.5V without a heat spreader relying on chassis airflow for cooling. It replaces Supermicro part numbers MEMDR380LCL01ER13 MEMDR380LHL01ER13 MEMDR380LHL03ER13 MEMDR380LHV01ER13 MEMDR380LSL02ER13 and MEMDR380LSL06ER13.

Perguntas sobre este artigo

Does the 1R3D32R408GB module ship as a single 8GB stick or do I need to order a kit?

The upgrade consists of one 8GB DDR3 1333 PC3-10600 CL9 2Rx4 240-pin 1.5V ECC Registered DIMM; no additional modules are included.

My Supermicro SuperServer 8026B has six DIMM slots — should I populate all six with this 8GB RDIMM or start with fewer?

OWC recommends using DIMMs of the same capacity, speed and manufacturer for optimal performance; you can install one module now and add matching modules later up to the platform limit.

What does the CL9 1333 MHz rating actually deliver inside a Supermicro 5086B Series server?

The module runs at DDR3 1333 (PC3-10600) with CAS latency 9, providing registered ECC bandwidth and error correction for the 5086B, 8026B and 8046B Series platforms.
