After staying quiet for most of last year, AMD has come in guns blazing in the processor market with the release of the 7000 series. While AMD was working on developing the 7000 series, Intel has been quite active and had a large market share due to the 12th Gen series. The Raptor Lake series is compatible with the newer memory technology DDR5 RAM. The previous 5000 series processors don’t support DDR5 since it’s a newer tech. However, the 7000 series does, so people wonder which RAM to use with the 7900X. But don’t worry; we have the list of products you want: the best RAM for Ryzen 9 7900X and the Ryzen 9 7900X motherboards too.
The Ryzen 9 7900X is a beast of a processor on paper as it boasts 12 cores and 24 threads with a base clock of 4.7 GHz and a boost clock of up to 5.6 GHz, translating to a solid real-world performance. The newer 7000 series comes on the newer AM5 socket since the previous socket, AM4, wasn’t compatible with DDR5 due to the extra PCIe lanes required by the RAM and CPU. Regarding the hierarchy, the 7900X is the direct successor of the 5900X, which is no slouch itself.
