Hello @Besjan
In addition to Silent_Scone’s forum post regarding memory installation and configuration, the purchasing and installation guide available on the ROG STRIX B650E-F GAMING WIFI support page > Memory QVL section provides the following information:
・Ensure that all memory modules are from the same validated memory kit. Do not mix DIMMs from different memory kits—even if they are the same brand and model (e.g., two DIMMs each from two different memory kits). Mixing and matching DIMMs can result in a failure to boot and compatibility issues. In particular, the stability of a system with mixed DIMMs cannot be guaranteed when XMP (Intel)/D.O.C.P (AMD)/EXPO (AMD)/AEMP/AEMPII is enabled. For example, enabling XMP (Intel)/D.O.C.P (AMD)/EXPO (AMD)/AEMP/AEMPII to speeds above DDR5 4800MHz or above DDR4 3200MHz could result in an unstable system.
You may also refer to [Motherboard] How to query (CPU/memory) QVL List? for further details.
Thank you.
