Compatible 32GB DDR4 module

This 32GB DDR4 DIMM runs at 2666MHz with CL19 timings and operates at 1.2V. It is built as a 2Rx8 unbuffered non-ECC stick using a major brand chipset. The module is designed for specific ASUS and Asmobile motherboards including the PRIME X570-PRO/CSM and several Z370 models.

Verify motherboard and capacity limits

Confirm your board appears in the supported list before ordering. The system maximum is 128GB across four sockets, so total capacity depends on how many slots you populate. A 64-bit operating system is required to address more than 4GB of memory. All installed modules will run at the speed of the slowest stick or the CPU limit.

Plain DIMM for standard slots

The stick uses a standard 288-pin layout with no heat spreader, so it fits ordinary DDR4 slots without clearance concerns. Mixing with other brands is possible but will default to the lowest common speed. Computer Memory Solutions provides a lifetime exchange or repair warranty against manufacturing defects when purchased directly from them.

Questions about this item

Does the 32GB CM4096642666DIMM stick ship alone or with extra parts?

The package contains one 32GB DDR4 2666MHz CL19 1.2V 2Rx8 unbuffered DIMM. No additional modules, cables or tools are included.

Should I pick the single 32GB module or a 64GB kit for my four-slot motherboard?

The board supports up to 128GB across four slots. A single 32GB stick leaves three slots open for later expansion; a 64GB matched pair enables dual-channel bandwidth from day one.

What does the 2666MHz CL19 rating mean once the stick is installed in my ASUS PRIME X570-PRO/CSM?

The module will run at 2666MT/s with 19-19-19 timings at 1.2V. If slower memory is also installed, all modules operate at the lowest common speed.
