High - frequency memory products in the American market, like DDR4 - 6400 and DDR5 - 8000, became the center of a class - action lawsuit titled "McKinney et al. v. Corsair Gaming, Inc.", which kicked off in 2022. The plaintiffs contended that these high - frequency memory offerings deviate from the JEDEC standard specifications (DDR4 - 2133, DDR5 - 4800). Instead, they are the outcome of the manufacturer's overclocking practices. Moreover, the plaintiffs asserted that manufacturers failed to clearly outline the necessary conditions for achieving such high frequencies, which amounts to deceptive marketing.

After over three years of legal wrangling, Corsair ultimately admitted defeat. The company agreed to pay a hefty $5.5 million in compensation. Additionally, Corsair committed to clearly indicating the "maximum frequency" on product packaging and promotional materials, along with the specific conditions required to attain that frequency. This compensation scheme encompasses desktop - grade DDR4 and DDR5 memory products that Corsair has sold in the U.S. between 2018 and 2025. Buyers can register for the compensation without having to present proof of purchase. The deadline for registration is set for October 28, 2025.
