How many people have upgraded the S4 firmware to: initramfs.bin.SD-20141016.tar.gz from the bitmain website?

I only ask because mine is still running on the factory firmware no problem with difficulty manually set, so I'm kind of wondering if I should bother with the upgrade.
I upgraded all of my S4's to this firmware and gained at least 5% hashing speed on the pool. I also set difficulty to 2048. 225 Mhz 0725 volts . They are all hashing at least 2200 and are stable meaning I don't have to hard reboot them every day for crashed chips or reduced hashing speeds.
After I reset to factory setting and set difficulty to 2048. 225 Mhz 0725 volts, I too am hashing at least 2200. It's very stable so far for past 24 hours. Thanks for the info.  Smiley
You bet brother. We are setting up 240 volts next week and I am going to overclock and see what happens.
