ASRock B660 DDR4 kit

This 32 GB kit contains two 16 GB DDR4 UDIMMs rated for 3200 MT/s at CL22 and 1.2 V. It targets builders upgrading compatible ASRock B660 motherboards with non-ECC unbuffered memory.

Dual-channel 288-pin layout

The two modules populate two DDR4 slots in dual-channel mode without requiring a heat spreader or registered buffers. Each stick is a 2Rx8 unbuffered DIMM that fits standard 288-pin desktop sockets.

Sustained 3200 MT/s operation

Modules are stress-tested under load at the rated 3200 MT/s speed and 1.2 V to maintain stability during extended workloads. The CL22 latency and unbuffered design keep timing consistent without ECC overhead.

Questions about this item

What is the CAS latency limit when the kit runs at 3200 MT/s?

The modules operate at CL22 when running at the rated DDR4 3200 speed.

How much power and heat does the 1.2 V unbuffered kit produce under continuous load?

At 1.20 V the dual-rank modules draw minimal power and run cool without a heat spreader.

Which motherboard series must I already own for this 288-pin kit to be compatible?

The kit is validated for ASRock B660M-HDV, B660M-ITX/ac and B660M-ITX/eDP boards.
