New X870E-E won’t post if I turn on EXPO

[panekko2]

Hi all,

I just assembled my new pc, and putting everything together it posts fine except for when I turn on EXPO mode to get my ram to 6000mhz. My ram is CORSAIR Vengeance 2x32gb. When I boot with EXPO mode it just gets stuck on code 15. I’ve tried waiting up to five minutes but it seems apparent it just doesn’t want to go anywhere.

Does anyone know why this could be? I’m lost

Hello @panekko2 

Thank you for reaching out to us, and sorry for any inconvenience caused by the delayed response.
Could you confirm the part number of the memory modules you have installed? Additionally, are they listed in the ROG STRIX X870E-E GAMING WIFI QVL?
Aside from ensuring that your BIOS is updated to the latest version 1203 and clearing CMOS, please try installing a single module in the DIMM_A2 slot first and enable EXPO I. Once stability is confirmed, proceed with installing the second module in the DIMM_B2 slot.
For details on memory compatibility, please refer to [Motherboard] How to query (CPU/memory) QVL List?
For guidance on enabling overclocking settings, please check the discussion thread Memory Kits - Overclocking and What You May Not Know.

Thank you.
