Flare X5 64GB DDR5 6000 CL28 Kit

This 64GB kit contains two 32GB DDR5 modules rated at 6000 MT/s with CL28 timings. It runs at 1.40V and uses AMD EXPO profiles for automatic configuration. The low-profile 33mm heat spreader fits tight CPU cooler clearances.

Suited For AMD Ryzen 7000 And 9000 Builds

Builders using Ryzen 7000 or 9000 series CPUs on X670, B650 or X870 motherboards will benefit from the EXPO support and tuned timings. Systems that require ECC or registered memory should choose a different kit.

CL28 At 1.40V Determines Compatibility

The CL28 28-36-36-96 timing set at 1.40V is the key specification that decides whether this kit matches your motherboard memory topology and CPU memory controller capabilities.

Questions about this item

Will the 33mm low-profile modules clear a large CPU cooler?

The Flare X5 sticks measure 33mm tall, so they fit under most tower coolers that leave standard DIMM clearance.

How do I enable the rated 6000 CL28 speed on a Ryzen 7000 or 9000 system?

Enter the BIOS, locate the AMD EXPO toggle, enable Profile 1, save and reboot — the kit will run at DDR5 6000 with 28-36-36-96 timings at 1.40V.

What happens if I later want to expand beyond the 64GB dual-channel kit?

The board must support four unbuffered DDR5 slots; you can add a second identical 2 x 32GB kit, but all four modules will run at the slowest common EXPO profile.
