Eight black DDR4 UDIMM modules without heat spreaders

OWC

OWC 64GB (8x8GB) DDR4 2400 CL17 desktop RAM

SKU CH-CP1P-YH3TR

Eight 8 GB DDR4 2400 CL17 modules provide 64 GB at 1.2 V for desktop PCs and workstations

  • Total capacity64 GB (8 × 8 GB)
  • Rated speedDDR4 2400 (PC4 19200)
  • CAS latencyCL17
  • Rated voltage1.2 V
  • Buffer typeUnbuffered
  • Kit configurationDual Channel Kit

Capacity 64GB (8 x 8GB)

  • 64 GB total capacity lets you run more apps and larger files at once
  • 2400 MHz DDR4 speed moves data quickly for responsive multitasking
  • CL17 latency keeps command delays low during heavy workloads
  • 2 V operation reduces power draw and heat inside the case
  • 288-pin unbuffered UDIMM fits standard desktop DIMM slots

Capacity and Kit Layout

This OWC kit supplies 64GB of DDR4 memory across eight 8GB unbuffered UDIMMs. It is intended for desktop PCs, workstations and NAS systems that can accept eight 288-pin modules.

Installation Context

The modules run at 1.2V and conform to JEDEC PC4-19200 specifications with a CAS latency of 17. They are non-ECC and unbuffered, so they fit standard consumer DIMM slots without requiring registered memory support. Backward compatibility with 2133MHz systems is included.

Sustained Operation

Each module is tested to meet OEM specifications and operates at the rated 2400MHz speed under continuous load. The standard voltage and lack of a heat spreader mean thermal behaviour follows the baseline DDR4 profile for long-duration workloads.

Questions about this item

What is the CAS latency that affects timing under sustained load?

The kit runs at CL17, which is the primary timing figure that limits latency during continuous memory access.

How much heat or noise should I expect when all eight modules run all day?

These unbuffered DIMMs operate at 1.2 V without heat spreaders, so they produce minimal heat and no audible noise under full load.

What motherboard feature do I need to use all 64 GB across eight slots?

You need a desktop board with eight 288-pin DDR4 slots that supports 64 GB total capacity and dual-channel operation.
