OWC 32GB (2x16GB) DDR3L 1600 CL11 ECC Registered RDIMM 1R6T32R4032P memory upgrade

SKU CH-634T-D9A49

A 32 GB dual-channel DDR3L ECC registered RDIMM kit running at 1600 MHz with CL11 latency and 1.35 V operation for compatible Supermicro SuperWorkstation 7037A, 7047AX and 7047GR systems

  • Total capacity32 GB (2 × 16 GB)
  • Rated speedDDR3L 1600 (PC3L 12800)
  • CAS latencyCL11
  • Rated voltage1.35 V
  • Buffer typeRegistered

Capacity 32GB (2 x 16GB)

  • ECC registered design protects data integrity in servers
  • 32 GB dual-channel kit expands workstation memory capacity
  • DDR3L 1600 CL11 timing matches Supermicro specifications
  • 35 V low-voltage modules reduce power draw
  • 240-pin RDIMM form factor fits 7037A, 7047AX, 7047GR systems

Targeted Workstation Upgrade

This 32GB kit contains two 16GB DDR3L registered DIMMs built for Supermicro SuperWorkstation 7037A, 7047AX and 7047GR systems. The modules operate at 1600MHz with CL11 latency and 1.35V power draw. ECC registered architecture prevents data corruption in server and NAS workloads. Standard desktop boards cannot use this memory.

Sustained Load Reliability

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC circuitry corrects single-bit errors in real time without halting the system. The 2Rx4 organisation supports dense capacity across both modules. JEDEC-compliant DDR3L signalling maintains stability at the rated 1600MHz speed.

Physical Integration

Each module uses a 240-pin DDR3L form factor without a heat spreader, fitting tight server DIMM slots. The 1.35V DDR3L voltage matches the platform specification exactly. Mixing with unbuffered DIMMs is not supported by the memory controller. Installation extends the service life of compatible Supermicro workstations.

Questions about this item

How much power does each 16GB DDR3L 1600 module draw at 1.35V?

Each 16GB module runs at 1.35V, the standard DDR3L voltage, reducing power draw and heat compared to 1.5V DDR3 during continuous operation.

What motherboard slot and memory type are required for these 240-pin RDIMMs?

You need a system with 240-pin DDR3L slots that support ECC Registered (RDIMM) memory; unbuffered or standard desktop boards will not work.

Can I mix these 2Rx4 Registered modules with existing unbuffered ECC DIMMs in a Supermicro 7047GR?

No, the manufacturer highlights state Registered memory cannot be mixed with unbuffered memory; all slots must use Registered ECC modules.
