Maximus Hero XI Bios V1502 - random lockup while making changes in Bios

Level 7

Less than one month old MB Hero XI. Updated the Bios to V1502 prior to completing this build. See Sig for details. No other issues.

Randomly when making a change from within the Bios, it will freeze and lockup. Sometimes I have to wait up to 45 - 60 seconds for it to respond to keyboard or mouse. A few times it has not responded and I had to power down. This happens maybe once every 20-30 times when in the Bios. NO boot issues, etc.

Can I reflash 1502 over the top of this one? Or should I revert back to previous and then bring it back to 1502?

Simple things I have done, reset cmos, changed to a new battery, cable check, etc. Different profiles and overclocks seem to have no bearing. Any Ideas?

if you have the non wifi version , you can go grab version 1602 and see if that helps..
