AMD EXPO DDR5 kit

This G.SKILL Flare X5 kit provides 16GB of DDR5 memory in a matched pair of 8GB modules. It is built for AMD Ryzen platforms using 600 or 800 series chipsets and carries AMD EXPO certification for one-click profile activation. The unbuffered DIMMs operate at a standard 1.20V.

5600 MT/s dual-channel capacity

The dual-channel kit delivers a rated transfer rate of 5600 MT/s (PC5 44800) with timings of 36-36-36-89 and a CAS latency of 36. That bandwidth handles modern gaming and multitasking workloads comfortably; heavier content-creation tasks that demand higher frequencies or lower latencies will require a faster kit.

Black heat spreader and EXPO profile

A low-profile black heat spreader covers each module to dissipate heat without adding RGB lighting. Enabling the AMD EXPO profile in the motherboard BIOS applies the rated 5600 MT/s speed and 36-36-36-89 timings automatically, removing the need for manual tuning while keeping the system stable on supported AMD 600, 650, 670, 800, 850 and 870 series boards.

Questions about this item

Will this kit work with an AMD B650 motherboard and a Ryzen CPU?

Yes, the kit is validated for AMD 600 and 800 series chipsets including B650 and is designed for Ryzen processors.

Is the rated 5600 MT/s speed automatic or do I need to enable a profile?

The modules boot at SPD speed by default; enable the AMD EXPO profile in the BIOS to reach the rated 5600 MT/s.

Can I add a second 16 GB kit later for more capacity?

The manufacturer advises against mixing kits; matched kits are tested to run together and mixing can cause instability.
