OWC 64GB (4x16GB) DDR3 1333 ECC Registered RDIMM 2Rx4 1.5V 240-pin Kit Supermicro 7036A 7046A

System-Specific DDR3 ECC Kit

This OWC kit delivers 64 GB of DDR3 1333 ECC registered memory across four 16 GB modules. It is built for Supermicro SuperWorkstation 7036A and 7046A systems that require 240-pin RDIMMs. The modules run at 1.5 V with CL9 latency and a 2Rx4 organisation. They are not compatible with standard desktop platforms or unbuffered memory.

Sustained Load Behaviour

ECC registered architecture corrects single-bit errors and reduces electrical load on the memory controller during continuous operation. Registered buffering allows the workstation to maintain stability when all four slots are populated at 1333 MHz. The 1.5 V rating matches the original platform specification for consistent thermal behaviour under long-running workloads.

Upgrade Context

This kit replaces Supermicro part MEMDR316LSL05ER13 and scales supported systems to 64 GB total capacity. The jump is worthwhile when virtualised environments, large datasets or multi-user services exceed the factory memory limit. Builders needing higher frequencies, lower voltages or consumer-form-factor modules should look elsewhere.
