Question Help with RAM compatibility.

Welcome to the forums! As said above nobody can tell. Specially when nobody knows your system spec.

Only certain thing is that mixing RAM is a gamble. There's not guarantee that two RAM moduels (even with identical specs) work peroperly together or even are able to POST and boot without issues that might require tweaking. That's why companies sell them as 'kits', that is RAM that comes as a 'kit' in one package.

Also it's customary to keep post title short and to the point and type the problem in the body of the post.
