Corsair Settles $5.5M Lawsuit Over Misleading Memory Speeds

Corsair has agreed to pay $5.5 million to settle a class-action lawsuit over allegedly misleading advertising of its memory module speeds. The case, filed in 2022, centred on Corsair DDR4 and DDR5 memory kits that prominently displayed advertised speeds on packaging without disclosing that default factory settings run at JEDEC standard speeds (DDR4-2133, DDR5-4800).

Consumers later found that those advertised speeds were not attainable without manual firmware adjustments for overclocking, with outcomes varying by CPU, motherboard and chipset. Although Corsair denied liability, it will add clearer disclaimers on product packaging and online listings stating that advertised speeds require enabling XMP/EXPO profiles and may not be universally achievable.

Eligibility for compensation covers U.S. customers who bought Corsair DDR4/DDR5 desktop memory kits between 14 January 2018 and 2 July 2025, with final payouts depending on the number of valid claims. Those who file a claim via the settlement website may be eligible for compensation for up to five products without proof of purchase, and more with receipts.
