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.
