HELP!! GTX 1070 low performance, TDP over 200% and core clock stucked 139mhz

[Aldora5070]

Hello there, im just getting a weird issue with my 1070. My bother gave it to me the last 2 days, and Im just be able to check it today.

Its giving a weird 139 mhz core clock whenever im idle or even when trying to play some games. Tried to run unigine heaven and the same problem occured.

I did run gpuz, and it gave me 240-250% TDP, and perfcap reason: PWR. Tried to run unigine heaven once or twice, thermal is good.

What I've tried: (nothing worked for me so far)
1. Reinstall driver (older one and the latest one). Running DDU between install
2. Changes power plan to Performance on control panel
3. Enabling K Boost on MSI Afterburner
4. Changing PSU, with different cable
5. Cleaning the graphic card and repaste it
6. Flashing other bios on to it

Looking for any advice on this graphic card.
System specs:
i7 6700 ES variant
Z170 ASUS Maximmus
8GB RAM
Inno3D 1070 Twin X2
Seasonic 860P Platinum PSU

First restore the original BIOS by following this thread.

Uninstall all display drivers and then perform a cleanup with Display Driver Uninstaller (DDU) from safe mode.

Take the PC outside, open the case, and remove all the dust with air blower or hair dryer with a cold setting.

Remove the graphics card and blow some air in the x16 PCI express slot.

Carefully remove the heatsink from the graphics card and clean the fans with a toothbrush.

Clean the graphic cards with isopropyl alcohol and cotton swabs. Especially the GPU area and PCIe pins.

When you're done, reapply thermal paste on the GPU, remount the heatsink, plug it back in.

Download and install the latest drivers from this link.

If the graphics card still doesn't work, check if it's under warranty, if it is, just RMA it.

If warranty expired, consider sending it to graphics cards repair lab, if there isn't any in your area, you can try the oven trick as the last resort.

Agree with all of this, but, before any of this, I would ask your brother what’s up with the card and, if you can, see if it works in their PC.

I doubt your brother would give you a dud on purpose, so best to check!

Edit: I actually just gave the list a skim after reading “BIOS” but having confirmed you’ve tried some of those things already, no need to repeat your labor

Try troubleshooting with the given steps above, but consider that this is typical of power delivery being shot and card being dead. What you get then is exactly this type of 'safe mode'
