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?
The whole history of issued fw is available somewhere for download? Bitmain on site, some fw deleted and not available. Thank you for advice.
Yes its disabled in the software (since around the new year) but depending on your board type it may not be possible on the hardware itself. I have the following if anyone needs them, but not all of them may be good useable firmwares.
