Nope You can't You'll need to just buy DDR3 RAM, or upgrade the motherboard and CPU if you want DDR4 Last edited

In this short video, I will explain how to check whether your motherboard supports DDR5 RAM So, you can't mix and match SDRAM, DDR, DDR2, DDR3, DDR4, or DDR5 memory on the same motherboard, as they won't function They may not even fit in the same
