NVIDIA QUADRO M2000 INVALID BIOS IMAGE

[redmello]

Hi

I have an NVIDIA Quadro M2000 with GM206 GPU.
I have a problem that I can't solve.
I use GPU-Z to extract the bios, MaxwellBiosTweaker to edit it and NVFLASH64 to flash it to the gpu.
The original was also uploaded to MaxwellBiosTweaker and saved.
However NVFLASH flashes the original correctly while with a change in the "common" tab of the entries "BoostClock" and "MemoryClock" of just 30 and 100 Mhz
it writes me that the image provided is invalid.

Can someone explain to me what I need to do to unlock the clock?

Thank you!
