I'm saving up to get a 5700X3D around Christmas, upgrading from a 5600G, but I want to make sure I prepare properly before I do the swap.
The RAM I bought couldn't match the C18 @ 4000 M/Ts advertised and still remain stable, but I managed to manually overclock to C16 @ 3666. Should I drop to JDEC specs before I upgrade, or is it a non-issue?
This is a pretty general statement without having more information.
If you're only changing the CPU, I wouldn't worry about it. It shouldn't affect the stability of your memory but at worst it won't boot and you'll have to go into the BIOS and change your settings.
