32GB DDR4 3200 UDIMM for ASRock B660M

This 32GB DDR4 3200 CL22 module is built for ASRock B660M motherboards. It runs at 1.20V as a 2Rx8 unbuffered non-ECC UDIMM. The 288-pin stick uses major OEM chips and has no heat spreader. It fits desktop PCs needing a single high-density upgrade.

Who this suits and who it does not

Builders upgrading compatible ASRock B660M boards with a single 32GB DIMM will benefit. Buyers needing ECC, registered modules, lower latency than CL22, a heat spreader, multiple sticks in a kit, DDR5, or compatibility with other motherboard brands should look elsewhere.

2Rx8 32GB density decides fit

The 2Rx8 32GB organisation determines whether the board recognises the full capacity. ASRock B660M-HDV, B660M-ITX/ac and B660M-ITX/eDP support this density. Systems limited to 1Rx8 or lower maximum per slot will not use the full 32GB.

Questions about this item

Does my ASRock B660M motherboard need a free 288-pin DDR4 slot for this 32GB UDIMM?

Yes, this single 32GB module occupies one 288-pin DDR4 UDIMM slot on any compatible ASRock B660M board.

Will this CL22 3200MHz stick run with my existing DDR4 modules at lower speeds?

The motherboard will down-clock all installed DDR4 to the slowest module’s speed and loosest timings, so mixing is possible but overall bandwidth drops.

How can I confirm the module is detected at 3200 MT/s with CL22 after installation?

Enter the UEFI/BIOS or use a tool such as CPU-Z to verify the memory shows 3200 MT/s, 1.20 V and CAS latency 22.
