Those wanting to see even more of the Linux benchmarks from this Corsair DDR5 memory kit can see this result page. For many of the more demanding workloads, the Corsair DDR5-7000 memory kit was providing some nice advantages over more common DDR5-6000 speeds even with the higher latency of DDR5-7000. For basic desktop usage though there is little outright performance advantage over DDR5-6000 with current generation processors. Besides the better performance in memory intensive workloads, the 48GB memory capacity at just $215 USD for the CMK48GX5M2B7000C40 kit is quite a nice value option.

It's unfortunate that the Corsair CMK48GX5M2B7000C40 kit wasn't working with the AMD Ryzen 9 7950X + ASUS X670E HERO combination at this time, but hopefully future BIOS updates will address it. At least for the Intel Core i9 13900K "Raptor Lake" system using the Corsair 2 x 24GB DDR5-7000 C40 memory kit has been working out great on Linux.
