Hello Paul323,

Thank you for posting in Intel community Forum.

Let me verify first if the components that you are using are known working units.

1. The i7-14700T is a known working processor? Did you already tried this on a retails board?
2. Have you also tried a different processor on your designed board?

If you have questions, please let us know. Thank you.
