64 GB DDR4 kit for ASRock B660M boards

This NEMIX RAM kit provides 64 GB of DDR4 memory in four 16 GB modules. It is built for desktop PCs using ASRock B660M motherboards such as the PG Riptide, Phantom Gaming 4 and Pro RS. The modules run at 3200 MHz with CL22 latency and 1.2 V operation.

Tool-free installation in standard DIMM slots

Each 288-pin UDIMM drops into the motherboard slots without tools or cables. The unbuffered, non-ECC design means the system recognises the memory automatically in most cases. Builders should seat all four sticks firmly and check the motherboard manual for the recommended population order to avoid a no-post condition.

3200 MHz DDR4 speed matches the board specification

The kit operates at DDR4 3200 (PC4-25600) with CL22 timing, which is the rated speed for the compatible ASRock B660M models. Systems that require faster memory or lower latency will not reach those targets with this kit.

Questions about this item

How can I verify the kit is running at 3200 MT/s and CL22 after installing the four 16 GB modules?

Open the BIOS or a tool such as CPU-Z and confirm the memory frequency reads 3200 MT/s with timings of 22-22-22 at 1.20 V.

What exactly ships in the box and is anything else required to use the memory?

The package contains the 64 GB kit — four 16 GB 288-pin DDR4 UDIMM modules — and nothing else; no extra cables, brackets or software are needed.

Should I choose this 64 GB (4×16 GB) CL22 kit or a different capacity or latency for my ASRock B660M board?

This 64 GB CL22 kit matches the supported DDR4 3200 specification for the listed ASRock B660M models; select a different capacity only if you need more or less total memory.
