Capacity and fit

This is a 32 GB DDR4 3200 module in a single 288-pin UDIMM. It runs at 1.2 V with CL22 timing and uses a 2Rx8 organisation. The stick is validated for the ASRock B450M-HDV R4.0 motherboard.

Who should buy and who should not

Desktop builders upgrading that specific ASRock board gain a simple capacity increase. Systems that require ECC, registered DIMMs, a different DDR generation, or a lower-profile module with a heat spreader will not be compatible with this part.

Deciding specification

The 32 GB density in a single rank-2Rx8 UDIMM is the figure that determines whether the board accepts the module; verify the motherboard’s maximum per-slot limit before ordering.

Questions about this item

How do I install this 288-pin DDR4 UDIMM into the ASRock B450M-HDV R4.0, and which step is often missed?

Align the notch on the module with the slot key, press firmly until both side clips snap shut, then verify in BIOS that the 3200 MT/s speed and CL22 timings are detected.

What maintenance or replacement will this 32GB 2Rx8 module need over time?

No routine maintenance is required; keep the slot contacts clean and ensure case airflow stays adequate so the 1.2 V DRAM remains within safe temperatures.

What limit appears first when this CL22 3200 MT/s kit runs sustained heavy workloads?

The CL22 latency at 3200 MT/s is the primary bottleneck; bandwidth scales with the 25600 MB/s rating, but tight timing-sensitive tasks hit the latency ceiling first.
