have you solved this problem? i have several S9 13.5T (auto-freq Nov 2017) that report 100+C chip temp on this bmminer880, want to try it with fix-650M firmware.
100C is normal if you're pushing it really hard on 880 with poor cooling but You should be having cooler temps. What Frequency are you running it at???
hi. i have some trouble with overclock.

Did you try to run the custom bmminer after flashing 650m or stop right there? Over 15th/s is good? I don't think I understand.
