High-capacity DDR5 kit for Intel platforms

This Corsair Vengeance RGB kit delivers 64GB across two 32GB modules. It runs at DDR5 5200 with a CL40 latency and 40-40-40-77 timings. Intel XMP 3.0 support allows simple one-click configuration on compatible motherboards.

Thermals and power at standard voltage

The aluminium heat spreader dissipates heat while the modules operate at 1.25V. RGB illumination adds negligible power draw and the memory produces no audible noise. Stable operation is maintained within the rated voltage and timing envelope.

Dual-channel layout fits standard desktop builds

The 288-pin DIMMs install in pairs to populate a dual-channel configuration. Ten-zone RGB lighting per module is controlled through iCUE software for custom effects. The kit is validated for Intel 600 series and Z490, Z590, Z690 chipsets.

Questions about this item

How do I install the 288-pin DDR5 modules and enable the Intel XMP 3.0 profile?

Align each 32GB stick with the motherboard slot notch, press down until the retention clips click, then enter the BIOS and enable the Intel XMP 3.0 profile to run at DDR5 5200 with CL40 timing.

What maintenance will the ten-zone RGB light bar and heat spreader need later?

Dust the heat spreader and light bar with compressed air every few months; the LEDs are sealed and require no further service or replacement.

At what point does the 1.25V voltage limit stability during sustained heavy workloads?

The modules are rated for 1.25V at DDR5 5200 CL40; pushing voltage beyond this spec is where instability typically appears first under prolonged load.
