Capacity and fit

This 32GB DDR4 module is built for owners of ASUS PRIME Z390 and Z490 motherboards who need a single-stick upgrade. The 288-pin DIMM fits the four memory slots on those boards and raises the system to a maximum of 128GB when all sockets are populated.

Speed ceiling and mixing rule

The stick runs at 2666MHz with CL19 timings at 1.2V, so the memory controller will not exceed that data rate. If slower or faster modules are already installed, every DIMM in the system will operate at the lowest common speed.

Plain build and daily handling

No heat spreader is fitted, keeping the profile low for tight CPU cooler clearances. The unbuffered, non-ECC design uses major-brand chips in a 2Rx8 layout, and the single-module pack means you add capacity one slot at a time.

Questions about this item

Should I choose the single 32 GB stick or look for a matched pair?

The kit contains one 32 GB module; installing two identical sticks in matched slots lets the board run dual-channel for higher bandwidth.

Will this DDR4 2666 CL19 module actually run at 2666 MHz in my Z390 or Z490 board?

The stick is rated DDR4 2666 (PC4 21300) CL19 at 1.2 V; the motherboard will set that speed automatically if the CPU memory controller supports it.

Does the 288-pin DDR4 DIMM fit every slot on the listed ASUS Prime boards?

Yes, each board has four 288-pin DDR4 slots and supports up to 128 GB total, so this 2Rx8 unbuffered DIMM installs directly.
