Hello, BattlePhenom.
May I ask if you have checked the device manager to see if there are any drivers that have not been updated?
For example, is there an exclamation mark in other devices > PCIE-related items?
Do you have enable the PCI Express Root Port?
According to the memory QVL list of the ROG STRIX Z690-A GAMING WIFI D4, G.SKILL F4-4000C15Q-32GTZR is listed, but it seems difficult to tell whether it is the model based on the memory information you provided.
It is recommended that you start by using the memory from the QVL list, then try installing one module at a time until you have installed the full kit using the recommended slots as listed in the motherboard user manual, and finally reset the BIOS settings to see if the error reappears.
If possible, please provide a screenshot of the error message.
Thank you.
Due to the ongoing regional holidays, my responses may be slightly delayed.
Thank you in advance for your patience. 🙂
