CORSAIR Dominator Titanium 64GB (2 x 32GB) DDR5 6400 (PC5 51200) Desktop Memory Model CMP64GX5M2B6400C32W

The CORSAIR Dominator Titanium CMP64GX5M2B6400C32W is a 64GB (2 × 32GB) DDR5-6400 desktop memory kit with CL32 timing and Intel XMP 3.0, suited to Intel 600- and 700-series system builders seeking high-speed memory for demanding PC workloads.

Recommended For

• Intel desktop users who run memory-heavy creative work—such as video editing—or keep many demanding applications open and want 64GB across two DIMMs.
• Builders of a white, RGB-lit Intel gaming PC who want memory that matches the build and can be customized or synchronized through CORSAIR iCUE.
• PC enthusiasts who are comfortable enabling Intel XMP in BIOS and checking motherboard and CPU support to target the kit’s rated DDR5-6400 speed.
• Streamers and power users who want 64GB for gaming alongside streaming, communication, and other active applications, rather than a kit aimed only at basic gaming.

Real-World Use Scenarios

• When editing complex video projects while keeping other creative apps and browser tabs open, 64GB gives the system more room for concurrent work and can reduce slowdowns caused by running short on memory. Puget Systems identifies 64GB as a practical target for many professional or complex creative workflows.
• When working with RAW video or demanding DaVinci Resolve and Fusion projects, 64GB can help avoid memory-capacity limits as project complexity grows; it is a useful baseline, not a guarantee that every editing workflow will benefit equally.
• When gaming while streaming, recording, and running chat or browser tools, the extra capacity leaves more room for those tasks to share memory. It is most useful when the combined workload approaches the limits of a smaller kit; it does not by itself guarantee higher frame rates or eliminate stutter.
• When building an Intel DDR5 desktop and wanting to use the kit’s rated memory profile, enable Intel XMP in BIOS and check that the CPU and motherboard support the selected settings; the rated speed is not necessarily active at default settings.
• When gaming is the main task and memory use already fits comfortably within the existing RAM, moving to this 64GB kit may provide extra capacity for future multitasking, but should not be expected to noticeably improve game performance on its own.
• When assembling a white-themed PC with a visible side panel, the white heat spreaders and configurable RGB lighting let the memory match the build; CORSAIR iCUE can coordinate its lighting with compatible CORSAIR components.
