OWC 1R3D32R408GB 8GB DDR3 1333 ECC Registered RDIMM 2Rx4 1.5V 240-pin

Server ECC RDIMM

This OWC DDR3 1333 module provides 8 GB of ECC registered memory for Supermicro SuperServer 6036T, 6046T, 7046A, 7046GT and 7046T systems. It uses a 240-pin form factor with 2Rx4 organisation and CL9 latency. The part is designed for server and workstation platforms that require registered ECC DIMMs and will not operate in standard desktop computers or alongside unbuffered modules.

Thermals and power

Operating at 1.5 V, the module follows standard DDR3 voltage levels for registered server memory. No heat spreader is fitted, so cooling depends on the server chassis airflow across the DIMM slots. Power draw remains within JEDEC limits for PC3-10600 registered parts during normal multi-user workloads.

Sustained load behaviour

Under continuous demand the registered buffer helps maintain signal integrity across fully populated channels. ECC corrects single-bit errors on the fly, preventing data corruption during long compute or virtualisation tasks. The module is validated as a direct replacement for Supermicro part numbers MEMDR380LCL01ER13, MEMDR380LHL01ER13, MEMDR380LHL03ER13, MEMDR380LHV01ER13, MEMDR380LSL02ER13 and MEMDR380LSL06ER13.
