ASRock B450M 32 GB DDR4 kit

This 32 GB kit contains four 8 GB DDR4 UDIMM modules built for ASRock B450M motherboards. It runs at 3200 MHz with a CAS latency of 22 and operates at the standard 1.2 V. The unbuffered non-ECC design suits desktop PCs that need a straightforward memory upgrade.

Single-deciding specification: 4 × 8 GB 288-pin DDR4

The kit provides exactly four 288-pin DDR4 sticks totalling 32 GB, so it fills every slot on a typical four-slot B450M board. Builders who need a different capacity, a different module count or a registered ECC layout must choose another part.

Suits ASRock B450M owners adding 32 GB

Ideal for users upgrading an ASRock B450M system to 32 GB with matched modules. Not for systems that require ECC, registered DIMMs, DDR5 memory, or a capacity other than 32 GB.

Questions about this item

What real-world speed will the 3200 MT/s rating deliver on an ASRock B450M board?

The kit runs at DDR4-3200 (PC4-25600) with CL22 timings at 1.2 V; actual frequency depends on the motherboard's memory controller and BIOS settings.

Does the DDR4 UDIMM interface limit the maximum capacity or rank configuration on this platform?

Each module is a 1Rx8 8 GB UDIMM; four slots are filled for 32 GB total, which matches the typical four-DIMM limit of B450M boards.

Will these 288-pin modules physically fit the ASRock B450M DIMM slots without clearance issues?

Yes, they are standard-height 288-pin DDR4 UDIMMs with no heat spreader, so they clear most CPU coolers and fit the board's four slots.
