What is your up time ? With tweak ?
arround 8 hrs
https://ibb.co/RTzqKwysorry that the last ss i have.. i dont know i would need it. i already change to gminer for testing just now.. For my LHR card core 1485 is better in term of efficiency than 1440. can go up to 1600 and adding more hash but also consume more power + dropping efficiency. Imo invalid in other miner (not TBM) related to memclock too high or need adding core (more power) to stabilize memclock. If still appear then try P0 same process adding core while begin memclock -400 from P2 step by step adding memclock. Still appear then should lowering memclock.
If we drop core down from 1440 to 1380, hash and power will drop. So ya core need to support mem.
