Eight black DDR4 UDIMM sticks without heat spreaders

OWC

OWC 256GB (8x32GB) DDR4 3200MHz CL22 desktop RAM

SKU CH-0EX6-CP6R1

Eight 32GB DDR4 3200MHz CL22 modules totalling 256GB for desktop PCs, workstations and NAS systems

  • Capacity256GB (8 x 32GB)
  • SpeedDDR4 3200 (PC4 25600)
  • CAS LatencyCL22
  • Voltage1.2V
  • ECCNo
  • Buffered/RegisteredUnbuffered

Capacity 256GB (8 x 32GB)

  • Massive 256GB capacity across eight 32GB modules for heavy multitasking
  • DDR4 3200MHz speed with CL22 latency for responsive desktop performance
  • Low 1.2V operation reduces power draw and heat output
  • JEDEC compliant and RoHS certified for broad motherboard compatibility
  • Backward compatible with 2133, 2400, 2666 and 2933MHz systems

256GB DDR4 3200MHz Kit

This OWC kit delivers 256 gigabytes of DDR4 desktop memory across eight 32GB unbuffered UDIMMs. Each module runs at 3200MHz with CL22 latency at 1.2 volts and conforms to JEDEC PC4-25600 specifications. The 288-pin non-ECC design targets standard desktop and workstation platforms.

Suited for High-Capacity Workloads

Content creators, virtualization hosts and NAS builders who need large memory pools will benefit from the 256GB total. Systems limited to four DIMM slots or requiring ECC registered memory should consider alternative configurations. The kit is backward compatible with 2133, 2400, 2666 and 2933MHz bus speeds.

Headroom for Heavy Multitasking

Eight ranks per module provide dense capacity for running many virtual machines, large media timelines or in-memory databases simultaneously. Workloads that exceed 256GB or demand error-correcting code will require a different memory class. JEDEC compliance ensures stable operation at rated speed.

Soalan tentang produk ini

Does my motherboard need eight free 288-pin DIMM slots to use all 8 modules?

Yes, this kit contains eight 32 GB UDIMMs; each one occupies a single 288-pin DDR4 slot, so you need eight available slots to install the full 256 GB.

Will the 3200 MHz modules run reliably if my current CPU or board only supports 2666 MHz?

The spec sheet lists backward compatibility with 2133, 2400, 2666 and 2933 MHz; the modules will automatically clock down to the highest speed your platform allows.

How can I verify the kit is running at the rated 3200 MT/s and CL22 after installation?

Open the BIOS or a tool such as CPU-Z and confirm the SPD shows PC4-25600, 3200 MT/s data rate and CL22 timings at 1.2 V.
