My pair of batch 2 S5 were delivered with cgminer v4.7.0 ( No extra-nonces support )

Without extra-nonces, S5 get unstable and crash often on Nicehash

Login to your miner and update your firmware like that

Very easy to do, take 90sec to reboot.

Now just add #xnsub command to nicehash/westhash pool

stratum+tcp://stratum.westhash.com:3334#xnsub

Latest S5 are delivered with latest firmware so you don’t need to care about that.

I set my Frequency at 375Mhz and get stable 1.25TH/s

Happy mining 😉
