Ripjaws M5 RGB 64GB DDR5 Kit

This 64GB kit contains two 32GB DDR5 modules rated at 6400 MT/s with CL32-39-39 timings. It targets gamers and enthusiasts building on Intel 700 series chipsets with 13th or 14th Gen Core processors. The white aluminum heatspreaders and addressable RGB lighting suit themed builds.

Thermals and Power at 1.40V

Operating at 1.40V, the modules rely on the aluminum heatspreaders to move heat away from the hand-screened ICs during sustained loads. No active cooling is included, so case airflow determines peak temperatures. The dual-channel layout keeps the memory controller load balanced across both sticks.

XMP 3.0 and RGB Sync Software

Intel XMP 3.0 stores the 6400 MT/s profile so the firmware can apply it with one BIOS selection. The RGB LEDs respond to Asus Aura, Gigabyte RGB Fusion, MSI Mystic Light and ASRock Polychrome Sync utilities for system-wide lighting coordination.

Questions about this item

How do I install the 288-pin DDR5 modules and enable the XMP 3.0 profile without skipping the BIOS step?

Insert each 32 GB stick into the motherboard DDR5 slots following the dual-channel layout in the manual, then enter BIOS and load the Intel XMP 3.0 profile to run at DDR5 6400 CL32 1.40 V.

What maintenance will the aluminum heatspreaders and RGB LEDs need over time?

Dust the white aluminum heatspreaders occasionally with compressed air; the RGB LEDs are solid-state and require no bulb replacement.

At what point does the CL32 1.40 V rating become the limiting factor during sustained workloads?

The kit is validated at DDR5 6400 with timings 32-39-39 at 1.40 V; pushing frequency or tightening timings beyond this spec is where stability limits appear first.
