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

SKU CH-GSKP-67Q5E

A 64 GB ECC registered DDR3 kit (four 16 GB modules at 1333 MHz) validated for Supermicro 7036A and 7046A workstations

  • Capacity64GB (4 x 16GB)
  • Type240-Pin DDR3 ECC RDIMM
  • SpeedDDR3 1333 (PC3 10600)
  • CAS LatencyCL9
  • Voltage1.5V

Capacity 64GB (4 x 16GB)

  • ECC registered design protects data integrity in servers
  • 64GB kit with four 16GB modules maximises workstation capacity
  • DDR3 1333 CL9 speed matches Supermicro 7036A and 7046A specs
  • 5V 240-pin RDIMM ensures correct voltage and form factor
  • 2Rx4 dual-rank organisation optimises memory controller efficiency

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.

Questions about this item

How much power does each 16 GB DDR3 1333 module draw at 1.5 V?

Each module operates at 1.5 V, the standard voltage for DDR3 1333, so power draw stays within JEDEC limits for registered ECC DIMMs.

What motherboard slots and chipset support are required for this 240-pin registered ECC kit?

You need a Supermicro SuperWorkstation 7036A or 7046A system with 240-pin DDR3 slots that accept registered ECC RDIMMs; standard desktop boards will not work.

Can I add these 2Rx4 registered DIMMs alongside existing unbuffered DDR3 modules in the same workstation?

No, registered ECC memory cannot be mixed with unbuffered modules; all slots must use registered ECC DIMMs for the system to function.
