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.

Based on the newer Zen4 tech, the 7000 series processors promise more performance, and so far, they are ruling the world of benchmarks. The 7900X is an X variant, meaning you can overclock it too. It has a TDP of 170W but delivers stellar performance in return. While the processor is extremely capable, it needs high-speed RAM to run at its maximum potential. The processor supports the newer DDR5 technology with RAM speeds up to 5200 MHz.

Even though it’s a newer technology, many companies have launched their DDR5 product lineup, and choosing a RAM that goes with your setup can be quite a hassle. Slower RAM can hinder your processor’s capabilities, and it will underperform and hence be unable to deliver the maximum number of FPS or result in Lag when running resource-intensive apps, which is why faster memory along with a fast graphics card is important for maximum performance.

However, we have rounded up these products so everyone looking for RAM to pair off with the Ryzen 9 7900x and also an effective CPU cooler to cool down that hot chip and makes an informed decision and can get the best overall PC experience they can get. So, without waiting further, let’s dive straight into the list.
