The Corsair Dominator Platinum RGB is the overall best RAM kit you can buy to pair with the Ryzen 9 7900X. With a balance of great aesthetics and performance, what else can you ask for? It has a sleek, matte black aluminum finish with a unique RGB strip design we have never seen before in ram kits made by other manufacturers. 

The RGB lighting is controlled by Corsair’s proprietary RGB technology and software called Corsair iCUE. The lighting is unique, bright, and vivid and stands out compared to any other memory kit on the market. iCUE offers a substantial amount of customization across different Corsair products and ensures a seamless sync.

The aluminum heat spreaders add up quite the height though, with the RAM reaching a total height of 56mm. In most CPU coolers, it would likely fit, but just in case, do verify the clearance for the cooler to avoid any clearance issues. 

The Corsair Dominator comes ahead of its competitors due to the high overclocking capability where it can offer speeds up to 6,000 MT/s. It is rated at 5,600MHz with a CAS 36 latency with timings of 36-36-36-76 while maintaining a voltage of only 1.25V on XMP 2.0 mode. Lower voltages tend to provide greater stability and heat dissipation. So the overclocking headroom is quite a lot. 

Using high-quality Samsung DRAM ICs, it also comes with Power Management ICs (PMIC) on its modules for stable and reliable overclocking and efficiency. On AIDA64 benchmarks, the Corsair Dominator has achieved reading and writing speeds of 70,000MB/s in comparison to its DDR4 counterpart with only 38,000MB/s.
