16 GB DDR4 3200 UDIMM for ASRock B550M-HDV

This NEMIX RAM module provides 16 GB of DDR4 memory rated at 3200 MT/s with CL22 latency. It uses a standard 288-pin unbuffered non-ECC design and operates at 1.2 V. The kit is built specifically for compatibility with the ASRock B550M-HDV motherboard.

Suits builders upgrading that specific board

The single 16 GB stick fits users who want a straightforward capacity increase on the ASRock B550M-HDV platform without mixing modules. It is not for systems that require ECC error correction, registered buffering, lower latency timings, or memory speeds beyond 3200 MT/s.

2Rx8 dual-rank organisation

The module uses a 2Rx8 configuration, meaning it has two ranks of eight-bit wide chips. This rank structure affects how the memory controller addresses the DIMM and can influence stability on boards with limited rank support per channel. Verify that your ASRock B550M-HDV firmware accepts dual-rank UDIMMs at the target speed.

Questions about this item

How much power does the 1.2 V DDR4 module draw when the system runs all day?

The module operates at a standard 1.2 V DDR4 voltage, keeping power draw low during continuous use.

What motherboard slot and chipset must I already have for this 288-pin UDIMM to work?

It requires a desktop board with a DDR4 288-pin UDIMM slot; the kit is validated for the ASRock B550M-HDV.

Will this CL22 3200 MT/s stick run stably alongside my existing slower DDR4 modules?

The memory will down-clock to match the slowest installed module, so it works with older DDR4 at the lower common speed.
