Crucial 16 GB DDR5-6400 CUDIMM CL52 1.10 V 288-pin

SKU CH-JV27-K9K02

A single 16 GB DDR5 module runs at 6400 MHz with CL52 latency and 1.10 V on a 288-pin CUDIMM for desktop PCs

  • 16 GB capacity runs heavy workloads smoothly
  • DDR5-6400 speed delivers 6400 MHz data rates
  • CL52 latency ensures fast response times
  • 10 V operation reduces power draw
  • 288-pin CUDIMM fits standard desktop motherboards

16 GB DDR5-6400 CUDIMM Module

This 16 GB DDR5 CUDIMM runs at 6400 MHz with CL52 latency at 1.10 V. It fits desktop motherboards that accept 288-pin DDR5 memory and is sold as a single stick for straightforward capacity upgrades.

Suits builders adding 16 GB to a compatible DDR5

Buyers whose motherboards do not support the CUDIMM form factor or the 6400 MHz data rate should look at other memory options. Systems limited to lower voltage operation or different pin layouts cannot use this module.

CUDIMM 288-pin form factor decides fit

The module uses the 288-pin CUDIMM layout, so it only works in desktop slots designed for that exact physical and electrical interface. Verify the motherboard manual for CUDIMM support before purchase.

Questions about this item

How do I install the CUDIMM module and which step do people often miss?

Align the notch on the 288-pin CUDIMM with the motherboard slot key, press down firmly until both retention clips click, then enter the BIOS to enable the 6400 MHz XMP or EXPO profile; skipping the BIOS step leaves the module at a lower default speed.

What maintenance or replacement will this 16 GB DDR5 module need later?

No routine maintenance is required; keep the slot and contacts free of dust, and if errors appear after years of use, run a memory diagnostic and replace the single 16 GB stick if it fails.

What limit appears first during sustained heavy workloads on this CL52 1.10 V kit?

The CAS latency of CL52 at 1.10 V sets the timing floor; under continuous load the memory controller hits that latency ceiling before thermal throttling becomes a factor.
