Call It DDR5.5 If You Prefer
If you’ve seen mention of CUDIMMs and are wondering what exactly they are, it’s perhaps not quite as interesting as you hope. Clocked Unbuffered Dual Inline Memory Modules are simply DDR5 DIMMs with exceptionally high clocks which are designed for Intel Core Ultra CPUs. The acronym is a little tortured to ensure there is a CU in the name, while not specifically mentioning Core Ultra in the standard.
These CUDIMMs are clocked at an impressive 8200 MT/s with timings of 40-52-52-135 that run, at least in KitGuru’s testing at a rather uncomfortable 1.4V. Corsair will be offering CUDIMMs running from 8000MT/s to 9200MT/s and while they do benchmark well you will be hard pressed to notice a difference while gaming. They also come at quite a premium, but you will get some bragging rights for your investment.
