Is it important that the 2x32 kit claims it supports Intel XMP? You're using a Ryzen 3900X.
I confirmed that point. Here are your questions rephrased:
1. Is the Intel XMP label on the 2x64 important?
2. With quad channel support, is it preferable to have four smaller sticks or two larger ones? The user mentioned it’s easier to push maximum performance with two 32 stick configurations since memory bandwidth caps at 128.
Generally it isn't, though each situation is different. 2. A CPU with quad-channel capability would significantly improve performance, but the 3900X only offers dual-channel support, so I’d choose a 2x32 configuration.
I noticed your concern. The compatibility details differ between Intel and AMD systems. Your setup is an Intel XMP profile, which isn't listed for AMD platforms.
