In what way is it not stable? Failing Prime or not even posting?

Any number of things may be wrong and the best way to troubleshoot is just to change one thing at a time and go back and run Prime.

Memory may be running too fast, or undervoltaged.

What are you settings at the moment?

yes, try losing your memory frequency and timings. That will leave you to set core and IMC voltages. When you are stable then set memory...

What are your CPU PLL voltages and IMC voltages?
