S5 Firmware Update Guide

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

Latest S5 Firmware include cgminer v4.8.0
Download here

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


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 😉
