16GB DDR4 module for ASRock B660M boards

This 288-pin UDIMM delivers 16GB of non-ECC unbuffered memory built specifically for ASRock B660M motherboards including PG Riptide Phantom Gaming 4 Pro RS and ProRS models. It installs in a single slot and operates at the standard 1.20V DDR4 voltage.

Runs at DDR4 3200 with CL22 latency

The module is rated PC4-25600 at 3200MT/s with a CAS latency of 22 cycles. Its 2Rx8 rank organisation and Samsung Micron or Hynix chips are validated for stability on the target platform.

Fits a single DIMM slot on compatible boards

The stick requires an open 288-pin DDR4 slot and a motherboard that supports unbuffered non-ECC UDIMMs at 1.20V. It leaves remaining slots free for additional capacity and does not need a heat spreader or extra clearance.

Questions about this item

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

The board will run the stick at DDR4 3200 with CL22 timings at 1.2 V, delivering PC4-25600 bandwidth without manual tuning.

How does the DDR4 UDIMM interface limit the usable speed on this platform?

The 288-pin unbuffered DDR4 slot caps transfer rate at 3200 MT/s, so the module operates at its rated ceiling without overclocking.

Will the 288-pin stick fit the four DIMM slots on my B660M Pro RS?

Yes, the standard 288-pin UDIMM form factor matches the four DDR4 slots on all listed ASRock B660M models.
