Got this firmware - https://github.com/KnCMiner/titan/releases/download/v1.97/titan-upgrade-1.97.bin works best for me.
And stratum+tcp://pool-adress:port/#xnsub#skipcbcheck#notls as pool adress and [F]ailover only enabled
.. that's it
First of all thank you for sharing your settings!
After 5 minutes I'm hashing with about 3-5 percent rejects and decreasing. I'm still at version 1.94 beta, added /#xnsub#skipcbcheck#notls and switched from "Load balance" to "Failover".
After 16 minutes only 1.6 percent reject rate
BTW why have you chosen Litecoins for the payout?
