OWC 16GB (2x8GB) DDR3L 1600 CL11 ECC Registered RDIMM 1Rx4 1.35V memory upgrade

SKU CH-GYQ3-SHGCH

ECC registered DDR3L kit adds 16 GB to compatible Supermicro A+ servers

  • Capacity16GB (2 x 8GB)
  • Type240-Pin DDR3L ECC RDIMM
  • SpeedDDR3L 1600 (PC3L 12800)
  • CAS LatencyCL11
  • Voltage1.35V
  • ECCYes

Capacity 16GB (2 x 8GB)

  • ECC registered design protects data integrity in servers
  • DDR3L 1600 CL11 speed matches Supermicro A+ specifications
  • 35 V operation reduces power draw versus standard DDR3
  • 16 GB kit (2 × 8 GB) fills two slots for balanced channels
  • Replaces Supermicro MEMDR380LHL07ER16 and three other part numbers

Targeted Server Upgrade

This 16GB kit provides two 8GB DDR3L 1600 CL11 registered ECC modules built for Supermicro A+ Server 2022TC, 2022TG, 4022G and 4042G systems. It is designed for workstations, servers, NAS devices and routers that require registered memory with error correction. Standard desktop computers cannot use these modules and they must not be mixed with unbuffered memory.

Sustained Workload Behaviour

JEDEC-compliant DDR3L chips run at 1.35V and maintain PC3L-12800 throughput during extended multi-tasking, virtualization or file-service loads. The registered buffer reduces electrical load on the memory controller, helping stability when all 16GB are populated across four channels in the supported Supermicro platforms. Every module is tested in-house before shipping.

Thermals Noise and Power

Low-voltage DDR3L operation keeps power draw modest compared with standard 1.5V DDR3, aiding thermal headroom in dense 1U or 2U chassis. No heat spreaders are fitted, so airflow through the server’s existing ducting cools the modules directly. Silent solid-state construction adds no acoustic noise to the system.

Questions about this item

How much power does each 8GB DDR3L module draw at 1.35V when the server runs continuously?

Each module operates at 1.35V, the standard DDR3L voltage, which reduces power draw and heat compared to 1.5V DDR3 while the server runs all day.

What motherboard feature must my Supermicro A+ server already have to accept these registered ECC DIMMs?

The motherboard must support 240-pin DDR3L registered ECC memory; these modules will not work in boards that only take unbuffered non-ECC DIMMs.

Can I add this 16GB kit alongside the existing 8GB Supermicro MEMDR380L modules already installed?

Yes, this kit replaces Supermicro part numbers MEMDR380LHL07ER16, MEMDR380LSL10ER16, MEMDR380LSL14ER16 and MEMDR380LSV04ER16, so it matches the registered ECC specification of those older modules.
