32GB DDR4 2666MHz DIMM for MSI boards

This 32GB DDR4 module runs at 2666MHz with CL19 timings at 1.2V. It is an unbuffered non-ECC DIMM built with a 2Rx8 rank configuration on major-brand chips. The kit contains a single 288-pin stick intended as a direct upgrade for the listed MSI motherboards.

Check your motherboard model and slot count

Verify that your board is one of the three MSI models named: MPG Z490 GAMING PLUS, MPG Z490M GAMING EDGE WIFI or PRESTIGE X570 CREATION. The platform supports a maximum of 128GB across four sockets. All installed memory will operate at the speed of the slowest module or the CPU limit. A 64-bit operating system is required to address more than 4GB.

Suits single-stick upgrades on validated MSI

This module suits builders adding 32GB to a compatible MSI Z490 or X570 board without filling every slot. It is not for systems that require ECC or registered memory. It is not for platforms limited to lower DDR4 speeds or different pin counts. Buyers needing matched-pair kits for dual-channel optimisation should look at two-stick packs instead.

Questions about this item

Does the 32 GB DDR4 2666 MHz CL19 kit include anything besides the single 288-pin DIMM?

The box contains only one 32 GB DDR4 2666 MHz CL19 1.2 V unbuffered DIMM; no cables, tools or additional modules are supplied.

Should I buy one 32 GB stick or two for the MSI MPG Z490 GAMING PLUS with four slots and 128 GB max capacity?

Two sticks enable dual-channel bandwidth on the four-slot board; a single stick works but runs in single-channel mode.

What does the PC4-21300 2666 MHz rating deliver when installed in an MSI Prestige X570 Creation motherboard?

The module runs at 2666 MHz with CL19 timings at 1.2 V; actual throughput depends on the CPU memory controller and BIOS settings.
