OWC 16GB (2x8GB) DDR3 1600 CL11 ECC Unbuffered UDIMM Kit

SKU CH-TM4W-VPV0S

A 16 GB dual-channel DDR3 1600 kit with ECC error correction for workstations and servers

  • SpeedDDR3 1600 (PC3 12800)
  • CAS LatencyCL11
  • Voltage1.5V
  • ECCYes
  • Buffered/RegisteredUnbuffered

Capacity 16GB (2 x 8GB)

  • 16 GB dual-channel kit expands multitasking headroom
  • DDR3 1600 CL11 timing keeps latency low
  • ECC unbuffered design protects data integrity in workstations
  • 5 V JEDEC-standard voltage ensures broad compatibility
  • 240-pin UDIMM form factor fits standard desktop slots

Kit composition and purpose

This OWC kit supplies 16 GB of DDR3 memory in a matched pair of 8 GB modules. It is built for desktop workstations, servers and NAS systems that require ECC protection and run at 1.5 V. The unbuffered design suits standard consumer and entry-level server boards.

Capacity and headroom

Two 8 GB DIMMs give a total of 16 GB running at DDR3 1600 with CL11 timing. This amount handles typical multi-tasking, virtualisation and file-serving workloads. Systems needing more than 16 GB will require additional slots or higher-density modules.

DDR3 interface limits

The modules use the 240-pin DDR3 form factor and operate at the JEDEC-standard PC3-12800 speed grade. Bandwidth and latency are fixed by the DDR3 1600 specification; faster DDR3 speeds or later DDR generations are not supported by this kit.

Questions about this item

Will the 240-pin DDR3 1600 CL11 modules work in my older workstation that only supports unbuffered ECC memory?

Yes, the kit uses 240-pin DDR3 1600 CL11 unbuffered ECC DIMMs at 1.5 V, matching the JEDEC PC3-12800 standard for compatible desktops, workstations and servers.

How can I verify the dual-channel kit is running at the rated 1600 MHz CL11 after installation?

Enter the system BIOS or UEFI and confirm the memory frequency reads 1600 MHz with CAS latency 11; CPU-Z or dmidecode will also show each 8 GB module operating at PC3-12800 1.5 V.

Does the 16 GB kit include only the two 8 GB DIMMs, or are any cables or tools supplied?

The box contains only the two 8 GB DDR3 1600 CL11 ECC unbuffered UDIMMs; no cables, screws or installation tools are included.
