MSFS Application Error - memory could not be read

Same. Sadly I just had another CTD. This was after I entered the beta (again), then started a flight in the B78XH from Brisbane to Port Moresby (around 3hrs). I went to bed and woke up to the CTD, so I’ve no idea when it happened.

At the time I had a core underclock of -100MHz and a default memory clock. I’ll try to decrease core clock further, to founders edition value, which is -165.

Oh, another thing is that I started adding addons. But at the time I didn’t have much installed: Brisbane city by Orbx, the 787 mod, a livery, nohandlebar, AIG.
