Model: Legion 5 15IAH7H
Describe the issue: my RTX 3070 has a power draw or sensor problems I'm not sure which, resulting in very low fps in games and any 3d software
What have you tried already?: I tried flashing a different vbios and bios
When did it start producing the issue: the moment I purchased it
Did you install new drivers or software?: I tried uninstalling with ddu and reinstalling different versions, nothing made a difference
Can you provide images/videos to show us the issue:

Ya that’s wild. Seems like your sensors are broke

There's no chance a vbios could fix it?

#

Actually the memory clock was constantly at 7000 MHz before I flashed a different vbios

#

With the new one it became variable but the core clock and draw power stay the same almost always

I wouldn’t think that would fix it. I’ve never seen sensors reading so wrong before.

#

Mainly your rail voltages and powers.

I understand yeah

#

Well thanks for the help mate, much appreciated

Other people may chime in with ideas about if it’s fixable or not.

Try to go back to stock bios then?

#

Also try different driver

#

Currently not, I actually tried another vbios in hope that it would resolve the issue

#

Well, I can't seem to find the stock bios anywhere

#

And I was stupid enough not to back it up

#

I tried the latest drivers as well as those on the lenovo product page but neither made a difference

#

Mistakes were made. I'm hoping that I somehow miraculously come across someone who has the same model as mine and that they'd be kind enough to upload their vbios for me
