Capacity and fit

This is a single 32GB DDR4 DIMM built for desktop systems that accept 288‑pin unbuffered memory. It targets users who need a straightforward capacity increase without ECC or registered buffers.

Speed and timing gate

The module runs at DDR4 3200 (PC4‑25600) with a tested CAS latency of CL22 at 1.20V. If your motherboard or CPU memory controller cannot operate at that frequency and timing, the stick will down‑clock or fail to post.

Installation notes

Align the notch on the 288‑pin edge connector with the slot key, press firmly until the retention clips click, and verify the BIOS recognises the full 32GB. The most common issue is mixing this CL22 module with faster or lower‑latency kits, which forces the entire array to run at the slowest common settings.

Questions about this item

Will this 32 GB DDR4 3200 module fit a standard desktop motherboard?

It uses the 288-pin DIMM form factor and 1.2 V DDR4 standard voltage, so it installs in any desktop board with a DDR4 slot that supports 3200 MHz or will down-clock automatically.

Does this module work in a dual-channel kit alongside another identical stick?

Yes, it is an unbuffered non-ECC UDIMM with 2Rx8 organization; adding a second matching module enables dual-channel operation on compatible motherboards.

Is this RAM a direct replacement for Crucial CT32G4DFD832A and CT2K32G4DFD832A?

The supplier lists it as a compatible equivalent for both Crucial part numbers, matching capacity, speed, voltage, latency and pin-out.
