CAS Latency · Color CL40 · Black

  • 64 GB dual-channel kit for high-capacity workloads
  • DDR5 6000 speed with CL40 latency for responsive performance
  • 35 V operation reduces power draw and heat
  • Black aluminium heat spreader keeps modules cool under load
  • Intel XMP 3.0 and AMD EXPO profiles simplify overclocking setup

Capacity and speed profile

This is a 64GB dual-channel kit built from two 32GB DDR5 modules rated at 6000 MT/s with a CAS latency of 40 and a 1.35V operating voltage. The black aluminium heat spreader covers both sticks and the kit carries no ECC or registered buffering.

Supported BIOS performance profiles

Intel XMP 3.0 and AMD EXPO profiles are both present so the rated frequency and timings can be loaded automatically on compatible motherboards. The modules are unbuffered desktop DIMMs intended for standard consumer platforms.

Deciding specification

The 6000 MT/s speed combined with CL40 latency at 1.35V is the single figure that determines whether this kit matches the memory controller capabilities of the target CPU and motherboard.

Questions about this item

Will this 64 GB kit run at 6000 MT/s on a motherboard that only supports the standard 4800 MT/s JEDEC speed?

The modules default to the standard JEDEC speed. To reach 6000 MT/s you must enable the Intel XMP 3.0 or AMD EXPO profile in the motherboard BIOS.

Does the 1.35 V operating voltage require a motherboard with a specific voltage regulator or BIOS setting?

1.35 V is within the normal DDR5 range. Most current desktop boards supply this voltage automatically when the XMP or EXPO profile is active.

The kit is a dual-channel pair of 32 GB modules. Will it work in a four-slot board if I populate only two slots?

Yes. Install the two modules in the slots designated for dual-channel operation (usually slots 2 and 4) and the board will run in dual-channel mode.
