Targeted DDR4 Upgrade

This 8 GB module is built for ASRock B660M PG Riptide, Phantom Gaming 4, Pro RS and ProRSax motherboards. It suits owners of those boards who need a single, validated stick to add capacity without guessing compatibility.

Decisive Specification

The kit runs at DDR4 3200 with a CL22 latency at 1.20 V in a 1Rx8 unbuffered layout. That exact speed, voltage and rank combination is what the listed ASRock boards expect, so the module will train at the rated frequency without manual tuning.

Build Integration

The 288-pin UDIMM drops into any free DDR4 slot on the supported boards and requires no heat spreader clearance. It leaves all other slots open for further expansion and draws standard DDR4 power from the motherboard without extra cables or cooling.

Questions about this item

What does the 3200 MT/s rating mean once the module is installed in the ASRock B660M board?

The module runs at DDR4 3200 (PC4-25600) speed with CL22 latency at 1.20 V, delivering the rated throughput when the motherboard enables the matching JEDEC profile.

How does the DDR4 UDIMM interface limit performance on this platform?

The 288-pin unbuffered DDR4 connection caps transfer rate at the 3200 MT/s JEDEC ceiling; no higher DDR4 speeds or DDR5 signalling are possible on this socket.

What physical slot and clearance does the stick need to fit the B660M PG Riptide?

It requires a standard 288-pin DDR4 UDIMM slot and has no heat spreader, so it fits under most CPU coolers without height interference.
