OWC 8GB DDR3L 1600 CL11 1Rx4 240-pin ECC RDIMM memory upgrade

SKU CH-Z6JK-PV0RY

An 8 GB DDR3L 1600 CL11 ECC registered DIMM for Supermicro X9DR server motherboards

  • Capacity8GB
  • Type240-Pin DDR3L ECC RDIMM
  • SpeedDDR3L 1600 (PC3L 12800)
  • CAS LatencyCL11
  • Voltage1.35V
  • ECCYes

Capacity 8GB

  • ECC registered design protects data integrity in servers
  • DDR3L 1600 speed with CL11 latency boosts throughput
  • Low 1.35V voltage reduces power draw and heat
  • Validated for Supermicro X9DRFF, X9DRFR, X9DRG, X9DRH, X9DRi boards
  • Single 8GB 1Rx4 module simplifies capacity expansion

Targeted Server Upgrade

This 8GB DDR3L registered ECC module runs at 1600 MT/s with CL11 latency and 1.35 V operation. It is built for Supermicro X9DR series motherboards including X9DRFF, X9DRFR, X9DRG, X9DRH and X9DRi models. The single-rank 1Rx4 design fits a standard 240-pin DDR3 DIMM socket.

Compatibility Guidance

It suits administrators extending the life of compatible Supermicro workstations, servers, NAS boxes or routers that require registered ECC DDR3L memory. It will not work in standard desktop PCs or any system that only accepts unbuffered non-ECC modules. Builders needing larger single-DIMM capacities or different voltage requirements must look elsewhere.

Deciding Specification

The module is a registered ECC DDR3L RDIMM, not an unbuffered UDIMM. That distinction alone determines whether the part will post in your Supermicro X9DR platform. Confirm the motherboard manual calls for registered ECC DDR3L before ordering.

Questions about this item

Does my Supermicro X9DRH motherboard need a registered DIMM slot to accept this 240-pin ECC RDIMM?

Yes, this module is a registered ECC DIMM and requires a motherboard with registered DIMM support such as the listed Supermicro X9DR series boards.

Can I install this 1.35 V DDR3L 1600 module alongside existing 1.5 V DDR3 registered DIMMs in the same server?

The module runs at 1.35 V; mixing voltages is not recommended and the system will typically default to the higher voltage, so use matching DDR3L modules for stability.

How can I verify the module is running at PC3L-12800 CL11 after installation?

Check the BIOS memory information or use a tool such as CPU-Z to confirm the reported speed is 1600 MHz with CAS latency 11 at 1.35 V.
