Hi,

I can not set the voltage chips. In the menu box for tension, but typing in any value after boot S3 + B11 unresponsive and I measured voltage of the chip voltmeter and there is still 0.760 V. Bitmain then somehow forbid editing tension in newer firmwares, right? You have what firmware and editing tension will really work?
Thank you for advice.

I buy defective Antminer C1, S3, S5 ... or individual parts. Thank you for the offer.
