Dominator Platinum RGB 32GB DDR5 Kit

This Corsair Dominator Platinum RGB kit delivers 32GB of DDR5 memory across two 16GB modules. It operates at 5200 MT/s with a CL40 latency and 40-40-40-77 timings at 1.25V. The modules feature RGB lighting and a gray heatspreader design.

AMD EXPO and Intel XMP 3.0 Ready

The memory supports both AMD EXPO and Intel XMP 3.0 profiles for automatic configuration. It is validated for AMD 7000 series processors on X670 and B650 chipsets. Builders using older AMD platforms or different DDR generations should verify compatibility before purchase.

5200 MT/s DDR5 Speed Rating

The decisive specification is the DDR5 5200 (PC5 41600) speed rating paired with CL40 timing. This combination sets the baseline performance and determines whether the kit matches the motherboard's qualified vendor list for stable operation.

Questions about this item

Will the 288-pin DDR5 modules fit my AMD X670 or B650 motherboard?

Yes, the 288-pin DDR5 design matches the slots on AMD X670 and B650 boards recommended for this kit.

How do I enable the rated 5200 speed, and what step is often missed?

Enter the BIOS and toggle on AMD EXPO or Intel XMP 3.0; the common mistake is leaving the profile disabled so the memory runs at a lower default speed.

When should I check or replace the Dominator Platinum RGB modules?

DDR5 modules have no scheduled maintenance; replace only if memory diagnostics report errors or the system becomes unstable after firmware updates.
