Compatibility with MSI B550M PRO-VDH WiFi

This 32GB DDR4 kit is validated for the MSI B550M PRO-VDH WiFi motherboard. It contains two 16GB unbuffered UDIMM modules that install directly into the desktop DIMM slots. The memory operates at 3200MT/s with a standard 1.20V voltage. Builders upgrading this specific board receive a matched pair tested for stability.

Suited for standard desktop upgrades.

The non-ECC unbuffered design fits typical consumer desktop workloads such as gaming, office applications and general multitasking. Systems that require error-correcting code or registered modules cannot use this kit. Buyers needing higher capacity per module or lower latency timings should consider alternative configurations.

Dual-rank 2Rx8 organisation at CL22

Each 16GB module uses a 2Rx8 rank structure, which affects how the memory controller addresses the chips. The CAS latency is rated at CL22 for the 3200MT/s speed grade. This timing and rank combination determines compatibility with the motherboard's memory topology and should be matched when adding further modules.

Questions about this item

How do I install the 288-pin UDIMM kit in the MSI B550M PRO-VDH WiFi motherboard?

Align the notch on each 16 GB stick with the slot key, press down firmly until both side clips click, then enable the 3200 MT/s profile in the BIOS

What maintenance or replacement will the memory need later?

No routine maintenance is required; the modules are covered by a lifetime replacement warranty if a fault develops

What limit appears first under sustained heavy workloads?

The CL22 latency at 1.20 V is the primary constraint during prolonged high-throughput use
