32GB DDR4 kit for Gigabyte Z390 and Z490 boards

This 32GB kit contains two 16GB DDR4 2400 modules rated CL17 at 1.2V. It is built as non-ECC unbuffered DIMMs for desktop platforms. The kit targets owners of the listed Gigabyte Z390 M Gaming and Z490 Aorus models who need a matched pair to reach the board's rated capacity.

288-pin DIMMs without heat spreaders

Each stick uses a 288-pin DDR4 interface and major-brand chips in a 2Rx8 organisation. The absence of a heat spreader keeps the module height low for tight CPU cooler clearances. Standard DIMM keying ensures a firm seat in any of the board's four slots.

Verify slot count and OS before ordering

The supported motherboards provide four DIMM sockets with a maximum capacity of 128GB, so this 32GB kit leaves room for future expansion. A 64-bit operating system is required to address more than 4GB of memory. Mixing with existing modules will force all memory to run at the slowest installed speed.

Questions about this item

What DDR4 speed and PC4 rating does the CM2048642400DIMM kit run at?

The kit runs at DDR4 2400 with a PC4 19200 rating, so the memory controller will cap data transfers at 2400 MT/s.

What physical slot and pin count do the two 16 GB modules need?

Each module is a 288-pin DDR4 DIMM and the supported Gigabyte boards provide four such slots, with a maximum of 128 GB across all four.

How should the pair be seated for dual-channel operation and what common step is missed?

Install the two sticks in the same-coloured slots — usually the second and fourth from the CPU — and press firmly until both side clips click; many builders stop at the first click and leave the module partially seated.
