32GB DDR4 3200 UDIMM for MSI B550-A PRO

This 32GB DDR4 3200 module is built for MSI B550-A PRO motherboards. It suits desktop users who need a single-slot capacity increase without mixing kits. The non-ECC unbuffered design matches standard consumer board requirements. It runs at 1.2V with CL22 timing.

Single 288-pin module with major OEM chips

The package contains one 32GB stick using Samsung, Micron or Hynix components. No heat spreader is fitted, keeping the profile low for tight CPU cooler clearance. The 2Rx8 organisation delivers 32GB in one slot, leaving remaining slots free for future expansion. Installation follows standard UDIMM procedure.

32GB capacity at DDR4 3200 speed

The 32GB capacity handles heavy multitasking, large media projects and virtual machines comfortably. DDR4 3200 (PC4-25600) bandwidth supports modern desktop workloads without bottleneck. The CL22 latency and 1.2V voltage are standard JEDEC values. Systems needing more than 32GB per slot or lower latency timings will require different modules.

Questions about this item

Will the single 32 GB stick need a matching module later for dual-channel performance?

Adding a second identical 32 GB DDR4 3200 CL22 UDIMM will enable dual-channel bandwidth on the MSI B550-A PRO, but the module works alone as shipped.

What stops the 3200 MHz speed from holding under long workloads?

The JEDEC-standard 1.20 V voltage and CL22 latency are rated for continuous operation; the motherboard's memory controller and cooling determine the real ceiling.

How much heat and power does the 2Rx8 module produce during all-day use?

At 1.20 V the stick draws standard DDR4 power and runs without a heat spreader, so case airflow handles the thermals.
