32GB DDR4 3200 UDIMM for desktop upgrades

This Crucial CT32G4DFD832A module delivers 32GB of DDR4 memory at 3200 MT/s with CL22 timings. It uses the standard 288-pin UDIMM form factor and operates at 1.20V. The stick is unbuffered and non-ECC, and it includes an Intel XMP 2.0 profile for automatic configuration on supporting platforms.

Suits single-slot 32GB upgrades.

Builders adding a single 32GB DIMM to a desktop board with a free UDIMM slot will find this module fits the requirement. Systems that demand ECC error correction or registered buffering cannot use this kit. Buyers who need a matched multi-module kit or a heat spreader should look elsewhere.

Deciding spec: 32GB capacity in a single

The key detail is that the full 32GB resides on one 288-pin UDIMM rather than split across two sticks. This leaves additional slots open for future expansion but means the memory controller must support 32GB density per rank. Verify the motherboard's qualified-vendor list for 32GB single-rank compatibility before purchase.

Questions about this item

How do I verify the module runs at 3200 MT/s with CL22 timing after installation?

Open Task Manager or CPU-Z and confirm the reported speed shows 3200 MT/s and timings read 22-22-22 at 1.20V.

What ships in the box and what must I source separately?

The box contains one 32GB 288-pin UDIMM; no heat spreader, cables or tools are included.

Should I choose the 3200 MT/s CL22 version or a lower-speed kit for my board?

The 3200 MT/s CL22 module downclocks automatically to 2933 MT/s or 2666 MT/s if the platform only supports those speeds.
