64 GB DDR4 kit for ASRock B450M boards

This 64 GB kit contains four 16 GB DDR4 UDIMM modules rated at 3200 MT/s with CL22 latency. It is built for desktop PCs that use ASRock B450M motherboards and accept non-ECC unbuffered memory. The modules operate at 1.2 V and use a standard 288-pin layout.

Suits builders expanding to 64 GB on a supported

The kit targets users who want a matched four-module set validated for the listed ASRock boards. It is not for systems that require ECC or registered DIMMs. Buyers needing capacities beyond 64 GB or speeds above 3200 MT/s should look at other memory lines.

2Rx8 dual-rank organisation

Each 16 GB module uses a 2Rx8 configuration, which affects how the memory controller populates slots on the motherboard. This rank structure is the key detail to verify against the board's qualified vendor list before purchase.

Questions about this item

Does this kit need 288-pin DDR4 slots on the motherboard?

Yes, each module is a 288-pin DDR4 UDIMM and requires four standard DDR4 DIMM slots to install the full 64 GB kit.

What is the correct way to seat the four 16 GB modules so the system recognises all 64 GB?

Insert each stick straight down until the side clips click, following the motherboard manual's recommended slot order for four-module population.

When would the 1.20 V DDR4 modules need to be replaced?

DDR4 memory has no moving parts; replacement is only needed if a module fails or a future upgrade requires higher capacity or speed.
