Hi guys ! I was wondering wich one of these two frequencies would be the best since I currently have ryzen 5 2400g. Also wich frequency would work best when a dedicated gpu is added and does it even make any difference then ?
Yes, there is a difference, but it does not seem great to me.
Ryzen is sensitive to ram, not all ddr4 ram is supported.
Double check that whatever you pick is supported by your motherboard QVL list or explicitly by the ram vendor selection app.
