With TBM I had to slightly lower my mem overclock, it was crashing all the time. Even with lower mem overclock rig restarts about 20 times per day.
Try to add --dagintensity 1 and --kernel 1. (kernel 1 low power, kernel 8 high power)
The dev fee is mined in the first 10 minutes of mining, so if your rig is crashing 20 times. The devfee is higher than normal. Dag is also taking a while to create, so a stable rig is important.
Ethermine reported hashrate in "ETH_WALLET1" is the full rig's speed not the 90% of the rig's full speed as it should (since the maintenance fee is 10%)
10% of the time is used to mine the maintenance wallet, so it will even out over time. 9 hours isn't enough. If the rig is crashing regulary, the factor might change.
because the maintenance wallet is starting around 20mins into the mining and will run a few seconds every 20 mins or so. So if your rig is mining for 19 minutes and crash every time, 0 to the maintenance wallet..
