MSI B550-A PRO compatible DDR4 UDIMM

This NEMIX RAM module delivers 8GB of DDR4 3200 memory built for the MSI B550-A PRO motherboard. It runs at 1.20V with CL22 timing in a 288-pin unbuffered non-ECC format. The single-rank 1Rx8 design uses major OEM chips for stable desktop operation.

Suits single-slot upgrades on the MSI B550-A PRO

Builders populating one DIMM slot on this specific board get a tested match. Buyers needing ECC error correction or registered buffering cannot use this module. Systems requiring lower latency than CL22 or a heat spreader should look elsewhere.

The deciding spec is MSI B550-A PRO validation

This part number MD25600-818K1 is qualified for that exact motherboard, removing guesswork from the upgrade. Without that validation, DDR4 3200 CL22 1.20V 288-pin UDIMM modules may not train correctly on the platform.

Questions about this item

Is the 8GB single module enough or should I add a second stick for dual-channel?

The module is sold as a single 8GB stick. Adding a second identical stick enables dual-channel bandwidth on boards with two or four slots.

What does the 3200MHz rating deliver on an MSI B550-A PRO?

The board runs DDR4 at 3200MHz with this CL22 1.20V module, giving the rated PC4-25600 throughput without manual tuning.

Does the 288-pin DDR4 interface limit the speed on this motherboard?

The 288-pin DDR4 UDIMM slot on the B550-A PRO supports the module's 3200MHz rating natively; no higher DDR4 speeds are possible on this platform.
