Kit contents

This 32 GB kit contains two 16 GB DDR4 DIMMs rated at 2400 MT/s with CL17 timings and 1.2 V operation. The modules are unbuffered, non-ECC and use a 2Rx8 organisation. They are built for MSI MPG Z490 GAMING PLUS, MPG Z490M GAMING EDGE WIFI and PRESTIGE X570 CREATION boards.

Upgrade path

The kit replaces slower or lower-capacity DDR4 memory in the listed MSI platforms. Moving to this speed and latency is worthwhile when the CPU and motherboard officially support DDR4 2400 and the workload benefits from the extra bandwidth. Mixing with slower modules will force all memory to run at the lowest common speed.

Capacity headroom

Each board accepts up to 128 GB across four slots, so this 32 GB kit leaves two free sockets for future expansion. The 64-bit operating system requirement applies for addressing more than 4 GB. Workloads that exceed 32 GB will need additional matched pairs to maintain dual-channel performance.

Questions about this item

Will these 288-pin DDR4 DIMMs fit the four slots on my MSI MPG Z490 GAMING PLUS motherboard?

Yes — the kit contains two 16 GB 288-pin DDR4 modules and the board provides four DDR4 DIMM sockets supporting up to 128 GB total.

What is the correct slot order when installing the two sticks on a Z490 board with four DIMM slots?

Populate the two slots of the same colour first (usually slots 2 and 4) to run in dual-channel mode; the motherboard manual labels them DDR4_2 and DDR4_4.

If I add another identical 32 GB kit later, will all four modules still run at 2400 MHz CL17?

All four 2Rx8 sticks will operate at the lowest common speed and timing — 2400 MHz CL17 — provided the CPU memory controller supports the full 64 GB population.
