Flare X5 48GB DDR5 Kit

The G.SKILL Flare X5 kit delivers 48GB of DDR5 memory in a dual-channel 2 x 24GB configuration. It is built for AMD Ryzen 7000 Series processors and runs at 5200 MT/s with a CL40 latency. The modules operate at 1.10V and support AMD EXPO profiles for simplified overclocking.

Capacity and Headroom

The 48GB capacity handles large creative workloads, heavy multitasking and modern games with ample headroom. Standard DDR5 5200 speed and 40-40-40 timings provide responsive performance for most applications. Extremely latency-sensitive tasks may benefit from tighter-timed or higher-frequency kits.

Low-Profile Build Integration

A compact 33mm module height clears most large CPU coolers and fits tight chassis layouts. The 288-pin DDR5 form factor requires a compatible motherboard with DDR5 slots. AMD EXPO and Intel XMP 3.0 profiles let the system train at rated speed through a single BIOS toggle.

Questions about this item

Will the 33 mm module height clear a large air cooler?

The low-profile height is 33 mm, so it fits under most large CPU coolers; verify your cooler's published clearance before installing.

Does this kit run at 5200 MT/s on an Intel platform?

The kit includes Intel XMP 3.0 profiles, so a supporting Intel motherboard can enable the rated 5200 speed with a single BIOS setting.

Is the 48 GB capacity (2 x 24 GB) supported by Ryzen 7000 CPUs?

Yes, the kit is validated for Ryzen 7000 series processors and uses dual-channel 24 GB modules for 48 GB total.
