CAS Latency CL30

  • 64 GB dual-channel kit gives ample capacity for demanding workloads
  • DDR5 6000 speed with CL30 latency delivers responsive performance
  • AMD EXPO support enables one-step overclocking on Ryzen 7000 platforms
  • Low-profile 33 mm heat spreader fits under large CPU coolers
  • Hand-screened ICs validated at 1.40 V for reliable operation

Flare X5 DDR5 64GB dual-channel kit

This 64GB kit contains two 32GB modules rated at DDR5 6000 with CL30 30-40-40-96 timings at 1.40V. It uses AMD EXPO and Intel XMP 3.0 profiles for one-step configuration on supported motherboards. The matte black heat spreader stands 33mm tall for clearance with larger CPU coolers.

Optimised for AMD Ryzen 7000 desktop systems

The modules are validated for AMD Ryzen 7000 Series processors and carry AMD EXPO profiles for automatic overclocking. Builders using older platforms or requiring RGB illumination will need a different memory kit. The low-profile design suits compact chassis and bulky air coolers where height is restricted.

CL30 30-40-40-96 latency at DDR5 6000

The CAS latency of 30 with 30-40-40-96 sub-timings defines the kit's responsiveness at its rated 6000 MT/s data rate. Buyers should confirm their motherboard and CPU memory controller can sustain this speed and timing combination before purchase.

Questions about this item

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

The modules stand 33mm tall, so they fit under most large air coolers; measure your cooler's published RAM clearance to confirm.

How do I enable the rated 6000 CL30 speed on my Ryzen 7000 system?

Enter the BIOS, locate the AMD EXPO toggle, and enable the profile — the kit ships with EXPO programmed for 6000 MT/s at 30-40-40-96 timings and 1.40V.

When should I expect to replace these 32GB modules?

DDR5 DRAM has no scheduled replacement interval; swap only if modules fail or if a future platform requires more than the 64GB dual-channel capacity.
