32GB DDR4 3200 UDIMM for ASRock B550M-HDV

This NEMIX RAM module delivers 32GB of DDR4 memory at 3200MHz in a single 288-pin UDIMM. It is built for the ASRock B550M-HDV motherboard using major OEM chips from Samsung Micron or Hynix. The kit runs at 1.2V with CL22 latency and requires no heat spreader.

Suitable for single-slot upgrades not

This 1x32GB configuration suits owners of the ASRock B550M-HDV who need maximum capacity in one slot. It is not for buyers who want matched pairs for dual-channel performance. It is not for systems that require ECC or registered memory. It is not for platforms limited to lower density modules.

2Rx8 dual-rank organisation

The module uses a 2Rx8 rank structure which determines how the memory controller addresses the 32GB density. This rank layout is the single specification that decides compatibility with the target motherboard. Verify that your board supports dual-rank UDIMMs at this capacity before purchase.

Questions about this item

Does the 288-pin UDIMM fit the ASRock B550M-HDV motherboard slots?

Yes, the 288-pin DDR4 UDIMM matches the standard desktop DIMM slots on the ASRock B550M-HDV motherboard.

What is the correct way to seat the module so the CL22 timing is recognised?

Align the notch with the slot key, press down firmly until both side clips click shut, then power on and enable the XMP profile in BIOS for 3200 MT/s operation.

Will the Samsung, Micron or Hynix chips need active cooling over time?

The module has no heat spreader and runs at 1.20 V; standard case airflow is sufficient for long-term stability.
