What this list covers
Prices and value ranks here cover new desktop DDR4 and DDR5 modules. Laptop, server and ECC and used memory have their own pages. A shared generation or capacity does not establish fit.
Speed, CAS latency and total capacity come from the maker's specification where the kit is matched to it, otherwise from the listing's title, so a kit appears here only when all three are stated. A shared speed and latency does not establish fit: check the motherboard's memory support list.

Will DDR5-8400 run at 8400 in my PC?
8400 MT/s is faster than any of the processors below is rated for, so this kit reaches 8400 only with its EXPO or XMP profile turned on in the motherboard's setup, which AMD and Intel count as overclocking. Without the profile it runs at a slower standard speed.
