16 GB DDR4 kit for ASRock B550M-HDV

This 16 GB kit contains two 8 GB DDR4 UDIMMs built for the ASRock B550M-HDV motherboard. It is intended for desktop owners who want a straightforward capacity increase without configuration hassle. The modules are validated for that specific board to ensure reliable operation.

CL22 latency at 3200 MT/s

The memory runs at DDR4 3200 (PC4-25600) with a CAS latency of CL22 and operates at 1.2 V. These three figures determine whether the kit matches the board's supported speed grade and timing window. No heat spreaders are fitted, so clearance is not a concern in compact builds.

Suits B550M-HDV owners needing 16 GB

Builders upgrading an ASRock B550M-HDV system to 16 GB will find this kit a direct fit. Users who require ECC error correction, registered modules, lower latency than CL22, speeds above 3200 MT/s, or capacities beyond 16 GB should look at other memory lines.

Questions about this item

What does the CL22 latency figure mean once the kit is installed?

CL22 is the CAS latency rating; the memory controller waits 22 clock cycles before data becomes available, so lower values would respond faster at the same 3200 MT/s rate.

How does the DDR4 3200 (PC4-25600) standard limit real-world throughput?

The DDR4 3200 standard sets the maximum data rate at 3200 MT/s; actual throughput depends on the motherboard memory controller and whether the two 8 GB modules run in dual-channel mode.

What physical clearance is needed for these 288-pin UDIMM modules?

Each stick is a standard-height 288-pin DDR4 UDIMM without a heat spreader, so it fits any desktop slot with normal vertical clearance and no oversized CPU cooler overhang.
