Four black DDR5 UDIMM sticks without heat spreaders

OWC

OWC 64GB (4×16GB) DDR5 5200 CL42 1.1V desktop RAM

SKU CH-X930-78EW5

Four 16 GB DDR5 modules running at 5200 MT/s with CL42 latency and 1.1 V operation for desktop upgrades

  • Capacity64GB (4 x 16GB)
  • SpeedDDR5 5200 (PC5 41600)
  • CAS LatencyCL42
  • Voltage1.1V
  • ECCNo
  • Buffered/RegisteredUnbuffered

Capacity 64GB (4 x 16GB)

  • 64GB kit expands multitasking headroom with four 16GB modules
  • DDR5 5200 speed delivers high bandwidth for demanding workloads
  • CL42 latency balances responsiveness with JEDEC-standard stability
  • 1V operation reduces power draw and heat output
  • 288-pin unbuffered non-ECC DIMMs fit standard desktop slots

Capacity and Configuration

This kit delivers 64GB of DDR5 memory in four 16GB modules, providing a dual-channel upgrade for compatible desktops. The unbuffered, non-ECC DIMMs operate at the standard 1.1V and use the 288-pin form factor.

Speed and Latency Headroom

Running at DDR5 5200 with a CL42 latency, the modules meet JEDEC PC5-41600 specifications for baseline performance. The standard voltage and timings leave limited manual overclocking headroom, so the kit is best suited for stock operation.

Build Integration

Installation requires a motherboard with four DDR5 slots that support 5200 MT/s and 1.1V JEDEC profiles. The low-profile black modules have no heat spreader or LEDs, fitting tight clearance around large CPU coolers while freeing all RGB headers for other components.

Questions about this item

Will the 5200 CL42 1.1V DDR5 modules run without errors when paired with my existing DDR5 sticks?

The kit is built to JEDEC standard 5200 CL42 at 1.1V. Mixing modules of different speeds or timings will force the system to run at the slowest common settings, so stability depends on whether your current sticks can operate at those parameters.

How can I verify the 64GB kit is running at 5200 CL42 after installation?

Open Task Manager or a tool such as CPU-Z and confirm the memory frequency reads 5200 MT/s with CAS latency 42. The BIOS memory info screen will also show the configured speed and timings for each 16GB module.

Does the 4×16GB package include only the four black unbuffered DIMMs, or are cables or a heat spreader also supplied?

The box contains the four 288-pin 1.1V DDR5 UDIMMs and nothing else — no cables, no heat spreader, no LED hardware. Any additional mounting hardware or cooling is sold separately.
