Dominator Platinum RGB 32GB DDR5 Kit

This Corsair Dominator Platinum RGB kit delivers 32GB of DDR5 memory across two 16GB modules. It is built for high-performance desktop systems and gaming rigs that need fast, responsive memory. The dual-channel configuration suits modern multi-core processors on AMD and Intel platforms.

CL32 Timing at 6400 MT/s

The modules run at DDR5 6400 with a CAS latency of CL32 and timings of 32-40-40-84 at 1.40V. Intel XMP 3.0 profiles let you enable the rated speed with a single BIOS setting. This combination of frequency and latency determines whether the kit matches your CPU and motherboard capabilities.

Compact Dual-Channel Modules for DDR5 Builds

The low-clearance 288-pin design fits comfortably under most CPU coolers and inside compact cases. Onboard voltage regulation works through Corsair iCUE software for stable tuning without motherboard-only control. The kit supports Intel 500 and 600 series chipsets including Z590, Z690, B660 and newer Z790 boards.

Questions about this item

Will this kit run at 6400 MT/s on a Z690 board with a 13th Gen Intel CPU?

Yes, the kit is validated for Intel 600 Series and Z690 chipsets with 13th Gen Intel CPUs and uses an Intel XMP 3.0 profile to reach 6400 MT/s at CL32.

Does the 1.40 V operating voltage need manual BIOS changes or is it handled by the XMP profile?

The Intel XMP 3.0 profile sets the 1.40 V automatically when enabled in the BIOS, so no manual voltage adjustment is required.

What clearance does the low-profile design leave for large CPU air coolers?

The compact form-factor is designed for wide compatibility with nearly any DDR5 build, including setups with bulky air coolers.
