You're experiencing inconsistent XMP performance with two different G.Skill RipJaws kits on your B450 Tomahawk OG and 2600. The first kit works fine, but the newer one from October 2021 doesn't hit the expected ratings. You plan to test the original kit alone to see if it can achieve XMP performance. It seems the RAM behavior varies between kits. You were considering buying the same SKU to avoid this issue.
