actually switching the driver to WDDM mode is not needed to control GPU voltages and clocks, it's a bug in nvidiaInspector.

if someone has its source code then it would be fairly easy to fix.

You can try test my open source NVAPI overclock tool. It is inspired / reverse engineered code from NVIDIA Inspector.

found the issue, tried 391 driver and got SMI to work properly. Going to try updating from that driver see what happens.

Edit: updated driver and back to same old thing. WDDM not working. Assuming somethings going on with newer Nvidia drivers. Going to try older 400 series driver next see what happens.

Edit #2: Seems 399 is working for SMI. for P104-100 I haven't seen any difference in wattage using Inspector vs MSIafterburner. at best 3 watts maybe?
Can confirm that drivers 399.07 and WDDM mode has made Inspector see P104-100. I managed to lower each card for about -15watts compared to Afterburner. Most cards work at 700 mV.

Glad to help! However I noticed serious hashrate drops when lowering voltage using Nvinspector around 1500-1600mhz is needed to achieve full hashrate with P104's. I've had mine Overclocked to +800 on memory +150 core @70% power on MSI afterburner. They're doing about 40-40.5mh/s @ 125w

P106s will more likely be different. Those should do about 65w-70w on ETH-hash.

Unfortinately, a lot of miners: T-Rex, CryptoDredge (coins with x16r algo and others), ccminer (ZCoin) work better with latest Nvidia drivers.

MSI Afterburner 4.6.0 Beta 10 can undervolt gpu core to 700 mV. But I have hashrate drops when lowering voltage P104 below 850mv. Same settings 1506core/ +700mem,  850mv 40mh/s, 800mv and lower drops to 35-37mh/s. This issue happens only with gigabyte p104, msi works fine. Any ideas what happens?

Finally I succedeed with P106-100 and 388.13 Nvidia drivers and nvidia-smi -dm 0. nvidiainspector is working now! Interesting that 388.77 drivers gave error 43 after nvidia-smi -dm 0 and restart.
