  • 32 GB kit (4 × 8 GB) expands workstation capacity
  • DDR3 1333 MHz CL9 matches Supermicro 7036A and 7046A specs
  • 240-pin 1.5 V registered DIMM fits qualified SuperWorkstation slots
  • Replaces six Supermicro part numbers for direct upgrade

Capacity & Configuration

This kit provides 32GB of DDR3 memory across four 8GB registered DIMMs. It is built for Supermicro SuperWorkstation 7036A and 7046A systems that require ECC registered modules. The 2Rx4 organisation and 1.5V operation match the original Supermicro part numbers listed by the manufacturer.

Compatibility Guidance

The modules suit administrators upgrading or repairing the named Supermicro workstations, as well as compatible server, NAS or router platforms that accept DDR3 1333 registered ECC DIMMs. Builders assembling standard desktop PCs, or any system that takes only unbuffered non-ECC memory, cannot use this kit. Mixing these registered DIMMs with unbuffered memory is not supported.

Deciding Specification

The memory is DDR3 1333 (PC3-10600) with CL9 latency, 240-pin registered ECC construction and 2Rx4 ranking. If your platform demands a different DDR generation, a different speed grade, unbuffered operation or a different rank structure, this kit will not function correctly.

Questions about this item

How much power does the 1.5 V DDR3 1333 kit draw when the workstation runs continuously?

Each module operates at the standard 1.5 V for DDR3 1333; total consumption depends on the Supermicro 7036A or 7046A platform and load, so consult the system documentation for exact figures.

What must my Supermicro SuperWorkstation already have to accept this 4×8 GB registered ECC kit?

The board needs free 240-pin DDR3 slots that support registered ECC RDIMMs; the 7036A and 7046A series are validated, and the memory cannot be mixed with unbuffered modules.

Will these CL9 2Rx4 RDIMMs work alongside the original Supermicro MEMDR380L modules I am keeping?

Yes — this kit replaces Supermicro part numbers MEMDR380LCL01ER13, MEMDR380LHL01ER13, MEMDR380LHL03ER13, MEMDR380LHV01ER13, MEMDR380LSL02ER13 and MEMDR380LSL06ER13, so it matches the registered ECC specification of those modules.
