64GB DDR5 Dual-Channel Kit

This Corsair Vengeance kit delivers 64GB of desktop memory across two 32GB modules. It runs at DDR5 5600 with a CL40 latency and 1.25V operating voltage. The 288-pin DIMMs include black heat spreaders and support Intel XMP 3.0 profiles for simplified configuration.

Intel 600/700 & AMD 500/600 Series Compatibility

The kit is validated for Intel 600 Series, Intel 700 Series, B560, B660 and B670 chipsets plus AMD 500 Series, AMD 600 Series, A520, B550 and B650 platforms. Builders using older chipsets or single-channel layouts should verify motherboard support before purchasing.

CL40 40-40-40-77 Timing Decides Fit

The decisive specification is the CAS latency of CL40 with 40-40-40-77 timings at 5600 MT/s. If your CPU or motherboard requires tighter sub-CL40 timings for stability or targeted workloads, this kit will not meet that requirement.

Questions about this item

Will the 288-pin DDR5 modules with their heat spreaders fit under a large CPU air cooler?

The Vengeance modules use a compact low-clearance form factor, so the black heat spreaders typically clear most oversized air coolers without interfering with the fan clips.

What is the correct way to enable the rated 5600 speed on a new build, and what step do builders often skip?

Install the two 32 GB sticks in the motherboard's primary dual-channel slots, enter the BIOS, and load the Intel XMP 3.0 profile; the step many miss is saving and exiting before the first boot.

Does the onboard voltage regulation or the heat spreader need any periodic maintenance?

No scheduled maintenance is required; the sealed heat spreader and integrated voltage regulation are passive, so only occasional dust removal with compressed air is needed.
