Capacity and Speed

This kit delivers 32 GB of DDR5 memory across two 16 GB modules running at 5600 MT/s with CL40 timings. Intel XMP 3.0 profiles allow automatic configuration on supported platforms. RGB lighting adds visual customisation for desktop builds.

Compatibility Fit

The modules are validated for AMD 500 and 600 series chipsets including B550, B650, X570 and X670, plus Ryzen and Threadripper processors. Intel 500 series platforms are also supported through XMP 3.0. Builders whose motherboards only accept earlier DDR generations should choose a different kit.

Deciding Specification

The operating voltage is set at 1.25 V, which determines whether a given motherboard can run the kit at its rated 5600 MT/s speed. Systems that cannot supply this voltage will fall back to lower frequencies. Check the board specifications before purchase.

Questions about this item

Will the 288-pin DDR5 DIMMs fit my motherboard's memory slots?

The kit uses the standard 288-pin DDR5 form factor, so it fits any desktop board with DDR5 slots.

How do I enable the rated 5600 MT/s speed via Intel XMP 3.0?

Enter the BIOS, locate the XMP 3.0 profile for this kit, enable it, save and reboot; the modules will then run at 5600 MT/s CL40 1.25V.

Can the RGB lighting be controlled without extra cables?

Yes, the RGB LEDs are powered through the DIMM slot itself and sync via motherboard software such as ASUS Aura Sync, MSI Mystic Light or Gigabyte RGB Fusion.
