Capacity and Compatibility

This 64 GB kit contains two 32 GB DDR4 3200 UDIMM modules validated for the ASRock B450M-HDV R4.0 motherboard. The unbuffered, non-ECC design suits standard desktop workloads and enthusiast builds that need a straightforward memory increase.

Physical Layout and Electricals

Each stick uses a 288-pin DDR4 form factor running at 1.20 V with CL22 timings and a 2Rx8 rank configuration. The modules ship without heat spreaders, so they fit in tight spaces around large CPU coolers while drawing standard DDR4 power.

Upgrade Path and Fit

The kit replaces lower-capacity or slower DDR4 DIMMs to reach the board's 64 GB maximum in two slots. The jump is worthwhile when applications benefit from the extra capacity at 3200 MT/s rather than dropping to a lower speed to populate four slots.

Questions about this item

What speed does the DDR4 3200 kit run at on the ASRock B450M-HDV R4.0 motherboard?

The modules are rated DDR4 3200 PC4-25600; the board’s memory controller will set the final operating frequency.

Will the 288-pin UDIMM modules clear the CPU cooler on the B450M-HDV R4.0?

These sticks have no heat spreader, keeping them low-profile for tight cooler clearances.

How do I install the two 32 GB sticks so the board runs dual-channel?

Populate the two DIMM slots of the same colour — usually slots two and four — then enable XMP in BIOS.
