32GB DDR4 3200 UDIMM for MSI B550M PRO-VDH WiFi

This 32GB DDR4 3200 module is built for the MSI B550M PRO-VDH WiFi motherboard. It uses a 288-pin UDIMM form factor with a 2Rx8 organisation and runs at 1.2V. The kit suits desktop users who need a straightforward capacity increase for everyday workloads and gaming.

Sustained load behaviour

The module operates at CL22 latency under the standard PC4-25600 specification. Without a heat spreader, the DRAM relies on case airflow to maintain rated speed during extended sessions. Stability is validated through stress testing, so the stick holds its frequency without throttling when the system is under continuous pressure.

Thermals, noise and power

Running at 1.2V keeps power draw low for a 32GB density. The bare PCB produces no fan noise of its own and adds minimal heat to the memory channel. Builders who prefer a quiet chassis will find the module unobtrusive, provided the case delivers adequate airflow over the DIMM slots.

Questions about this item

Does the 1.2V DDR4 3200 module run hot or loud during continuous all-day workloads?

The stick operates at standard 1.2V with no heat spreader, so it relies on case airflow; it has no moving parts and therefore produces no audible noise.

What must my desktop already have to accept this 288-pin UDIMM?

A DDR4 motherboard with a free 288-pin DIMM slot that supports 3200 MT/s unbuffered non-ECC memory and can address a 32 GB 2Rx8 module.

Will this CL22 3200 MT/s kit down-clock reliably next to slower DDR4 sticks I keep installed?

The module is rated for 3200 MT/s CL22 at 1.2V and will automatically run at the lowest common speed and latency of all installed DIMMs.
