OWC 1R6T32R416GB 16GB DDR3L 1600 ECC Registered RDIMM memory upgrade

SKU CH-KTRP-RAKRG

16 GB DDR3L 1600 ECC registered RDIMM for Supermicro H8 series servers

  • Total capacity16 GB
  • Rated speedDDR3L 1600 (PC3L 12800)
  • CAS latencyCL11
  • Rated voltage1.35 V
  • Buffer typeRegistered
  • Memory rank2Rx4

Capacity 16GB

  • ECC registered design prevents data errors in critical workloads
  • 16 GB capacity on a single module expands server memory headroom
  • DDR3L 1600 speed at 1.35 V reduces power draw versus standard DDR3
  • 240-pin RDIMM form factor fits Supermicro H8 series motherboards
  • 2Rx4 dual-rank organisation increases memory density per slot

Targeted Server Upgrade

This 16GB DDR3L ECC Registered RDIMM is built for Supermicro H8DCT, H8DG6, H8DGT, H8DGU and H8QG7 motherboards. It serves workstations, servers, NAS systems and routers that require registered error-correcting memory. Standard desktop boards cannot use this module, and it must not be mixed with unbuffered DIMMs. Buyers needing non-ECC or unbuffered memory for consumer platforms should look elsewhere.

Capacity and Headroom

A single 16GB module (2Rx4 organisation) adds substantial capacity to compatible multi-socket servers running virtualisation, database or file-service workloads. The DDR3L 1600 PC3L-12800 CL11 specification delivers the bandwidth these platforms expect. Systems that require higher densities per slot or faster transfer rates than 1600 MT/s will exhaust this module's headroom.

Thermals Noise and Power

Operating at 1.35V without a heat spreader, the module runs cool within the airflow of a typical server chassis. The low voltage reduces power draw compared with standard 1.5V DDR3, aiding thermal margins in dense configurations. No active cooling is present, so silent operation depends entirely on the host system's fan profile.

Questions about this item

Will this DDR3L 1600 CL11 2Rx4 registered module run alongside existing DDR3L DIMMs in my Supermicro H8DG6?

This module is DDR3L 1600 PC3L-12800 CL11 2Rx4 1.35V ECC Registered. Mixing speeds or ranks may force the system to run all DIMMs at the lowest common speed and could cause instability; matching specifications is recommended.

How can I verify the 16GB DDR3L 1600 ECC Registered module is detected and working after installation?

Enter the BIOS or UEFI on the Supermicro H8DCT, H8DG6, H8DGT, H8DGU or H8QG7 board and confirm the full 16GB capacity, DDR3L 1600 speed, ECC Registered status and 1.35V voltage are reported correctly.

What comes in the box with the OWC 1R6T32R416GB 16GB DDR3L 1600 ECC RDIMM and do I need anything else?

The package contains a single 16GB 240-pin DDR3L 1600 PC3L-12800 CL11 2Rx4 1.35V ECC Registered RDIMM. No extra cables, brackets or software are required for installation.
