Targeted MSI Upgrade

This 16 GB DDR4 module is validated for the MSI B550M PRO-VDH WiFi motherboard. It suits DIY builders and IT staff who want a single-stick capacity increase without mixing kits. The 2Rx8 organisation and 1.2 V operation match the board’s native memory topology.

Build Integration

The 288-pin UDIMM drops into any free DDR4 slot on the supported MSI platform. No heat spreader means low-profile clearance for oversized CPU coolers or compact chassis. Non-ECC unbuffered design keeps the memory controller configuration simple and predictable.

Capacity And Headroom

At 3200 MT/s with CL22 timing the stick handles everyday multitasking, office suites and mainstream gaming workloads. Heavy content-creation projects or virtual-machine clusters will exhaust the single 16 GB rank before the bandwidth ceiling becomes the bottleneck.

Questions about this item

Does the 2Rx8 dual-rank layout limit how many 3200 MHz modules the B550M PRO-VDH WiFi can run at full speed?

The board supports up to two dual-rank UDIMMs at DDR4 3200; adding a third module of this type will force the memory controller to drop the frequency.

How much heat does a 1.2 V CL22 stick produce during an all-day workload?

At 1.2 V and CL22 the module runs cool enough that no heat spreader is fitted; typical sustained power stays well within the board's standard DIMM cooling.

What must the motherboard already provide for this 288-pin UDIMM to work?

A DDR4 288-pin UDIMM slot wired for 1.2 V non-ECC unbuffered memory — exactly what the B550M PRO-VDH WiFi supplies.
