Flare X5 128GB DDR5 6000 Kit

This G.SKILL Flare X5 kit delivers 128GB of DDR5 memory in a dual-channel pair of 64GB modules. Rated at 6000 MT/s with CL36 timings and a 1.25V operating voltage, it targets enthusiasts and professionals who need high capacity for demanding workloads or gaming on modern platforms. The low-profile 33mm heat spreader ensures compatibility with larger CPU coolers.

Suited for AMD EXPO and Intel XMP 3.0 Systems

Builders using AMD 600- or 800-series chipsets such as B650, X670, B850 or X870 can enable AMD EXPO profiles for automatic overclocking. Intel 600-, 700- and 800-series platforms are also supported via XMP 3.0. Buyers who need ECC error correction or registered modules should look elsewhere, as this is a standard unbuffered desktop kit.

128GB Capacity Decides Fit

The 2 x 64GB configuration provides 128GB total capacity, which is the single specification that determines whether this kit meets your workload requirements. Systems limited to lower maximum memory per slot or lower total capacity will not be able to use the full kit. Verify your motherboard and CPU memory limits before purchase.

Questions about this item

Will the 33 mm low-profile height clear my large CPU air cooler?

The modules measure 33 mm tall, which is lower than standard DDR5 sticks, so they fit under most tower coolers without interfering with the fan clips.

Do I need to enable anything in the BIOS to reach DDR5 6000 CL36?

Yes, select the AMD EXPO or Intel XMP 3.0 profile in the BIOS; the kit stores both, so the correct timings of 36-44-44-96 at 1.25 V load automatically.

Is this 128 GB kit (2 × 64 GB) supported on a B650 or X670 motherboard?

The kit is validated for AMD 600-series chipsets including B650 and X670, and the dual-channel 2 × 64 GB configuration works within the board's maximum capacity limits.
