Micron has launched new DDR5-6400 memory kits to compete with the best RAM money can buy. However, these are normal UDIMMs and should not be confused with the DDR5-6400 CUDIMMs that hit the retail market earlier this month.
Targeting gamers, overclockers, and DIYers, the Crucial Pro Overclocking DDR5-6400 memory kits are manufactured with Micron's state-of-the-art 1ß (1-beta) process node, known for its performance, quality, and reliability. The previous highest data rate available from the Crucial Pro Overclocking lineup was DDR5-6000, so it's great to see Micron offering faster memory kits, even if the company's taking baby steps to climb the frequency ladder.
The memory kits are rated for DDR5-6400 and support Intel XMP 3.0 and AMD EXPO technologies. That means you can get the memory modules up and running at the advertised frequency with a single click inside your motherboard's BIOS. Officially, the Crucial Pro Overclocking DDR5-6400 memory kits support Intel 12th Generation Alder Lake, AMD Ryzen 7000, and newer processors.
The latest Ryzen 9000 chips don't natively support DDR5-6400. On the other hand, Intel's Core Ultra 200S processors do, but only with CUDIMMs. Therefore, there isn't a current platform where DDR5-6400 plug-and-play is guaranteed. However, DDR5-6400 is a mundane data rate by today's standard, so it shouldn't be an issue for most processors.

Micron is initially launching the Crucial Pro Overclocking DDR5-6400 memory in 16 GB densities. You can buy a single memory module or a dual-channel 32GB (2x16GB) memory kit. As always, color options are available in white or black.
Micron bins the Crucial Pro Overclocking DDR5-6400 memory kits with 38-40-40-84 timings. The memory modules require 1.35V to run with the aforementioned data rate and memory timings. The specifications are worse than the Crucial Pro Overclocking DDR5-6000 memory kits.
The Crucial Pro Overclocking DDR5-6400 memory timings are average. The kit obviously can't rival some high-end, competing DDR5-6400 memory kits with a CAS Latency (CL) of 30.
Like all Micron memory products, the Crucial Pro Overclocking DDR5-6400 memory kits have a limited lifetime warranty. The 32GB (2x16GB) black memory kit costs $118.99. The white variant, however, sells for a small premium at $127.99.
