I bent 10 bells of poop out of my bios trying to catch Splave the other day to the point my board would not pass more than a few turns of 32m with any ram at any speed. Not sure its exactly the done thing but I re flashed & hit cmos clear then updated mei again then cmos clear. I did this twice then backed up bios a - b booted & rebooted a couple times & all is well again.... might be worth a go if you cant get anything to run :shrug:
