Who This Suits

Builders upgrading or repairing one of the listed X299 boards who need a matched pair of non-ECC modules without a heat spreader. Buyers who want more storage, RGB lighting, ECC support or speeds above 2400 MHz should look at something else.

Capacity and Headroom

The kit delivers 16 GB total and works within the board's 64 GB four-slot limit for 16-lane CPUs or 128 GB eight-slot limit for 28-lane and 44-lane CPUs. It runs out when the workload exceeds 16 GB or requires registered memory.

Questions about this item

What motherboard must I already own for this 288-pin DDR4 2400 kit to be guaranteed compatible?

The kit is validated for Gigabyte X299 AORUS Ultra Gaming, X299 AORUS Ultra Gaming Pro, X299 DESIGNARE EX, X299 UD4 EX, X299 UD4 and X299 UD4 Pro motherboards.

Will the 2Rx8 rank organisation of these modules work in the 8 DIMM slots of my X299 board when paired with a 44-lane CPU?

Yes, the board supports up to 128 GB across 8 DDR4 DIMM sockets with a 44-lane or 28-lane CPU, and each 8 GB stick uses a 2Rx8 configuration.

How can I confirm the memory is running at DDR4-2400 CL17 after installation?

Check the BIOS or a system-information tool; it should report 2400 MHz speed, 17-17-17 timings and 1.2 V voltage for the kit.
