Single black 16GB DDR5 UDIMM module with 288 gold pins and no heat spreader

OWC

OWC 16GB DDR5 5600 ECC Unbuffered UDIMM CL46 1.1V desktop RAM

SKU CH-7W8V-T96FT

16 GB DDR5 5600 ECC unbuffered UDIMM with CL46 latency at 1.1 V for workstations, servers and NAS systems

  • Capacity16GB
  • SpeedDDR5 5600 (PC5 44800)
  • CAS LatencyCL46
  • Voltage1.1V
  • ECCYes
  • Buffered/RegisteredUnbuffered

Capacity 16GB

  • ECC protection guards data integrity in workstations and servers
  • DDR5 5600 speed delivers high bandwidth for demanding workloads
  • 1 V operation reduces power draw and heat output
  • 16 GB single module simplifies capacity upgrades
  • JEDEC-standard compliance ensures broad platform compatibility

Single-module 16 GB ECC upgrade

This OWC DDR5 UDIMM delivers 16 GB of ECC unbuffered memory at 5600 MT/s with a CL46 latency and 1.1 V operation. The 288-pin module targets desktop workstations, servers and NAS units that require error-correcting code for data integrity. No heat spreader or LEDs are fitted.

JEDEC-standard DDR5 5600 integration

The stick conforms to the PC5-44800 JEDEC specification, so it drops into any DDR5 slot wired for unbuffered ECC without BIOS tuning. Its single-rank 1Rx8 organisation leaves additional slots free for future capacity expansion. The 1.1 V rating keeps power draw low for always-on server or NAS deployments.

Suited for ECC-dependent workloads

Builders running ZFS, virtualization hosts or scientific workloads gain the single-bit error correction that consumer modules lack. Systems limited to non-ECC memory or requiring registered DIMMs cannot use this module. Buyers needing RGB lighting or aggressive heat spreaders should look elsewhere.

Questions about this item

How much heat does the 1.1 V DDR5 module add when it runs continuously in a workstation?

The module operates at 1.1 V with no heat spreader, so it adds minimal thermal load during sustained workloads.

What motherboard slot and chipset support is required for this 288-pin ECC unbuffered DIMM?

A DDR5 desktop or workstation board with a 288-pin UDIMM slot that accepts ECC unbuffered memory is required.

Does the single 16 GB stick work alone or must it be paired for ECC to function?

The 1Rx8 16 GB module functions independently; ECC operates on a single DIMM without a matched pair.
