After installing the latest geforce drivers

I tried dota 2, and i had like 10 fps, i loaded up a onscreen display to found out my GPU was stuck at 225mhz clock.

When it supposed to be 900.

Its not warm at all, 60 degrees.

Tried PRAM reset.

Heres a pic from nvidia inspector, notice it says invalid bios?

Try PRAM reset again. Sometimes the attempt won't register for some reason. I've had to try a reset up to three times on occasion for things to finally go back to normal.

Also, it's probably SMC reset that you want to do (again, sometimes you have to try it a few times before it resets.) PRAM reset probably isn't going to affect your issue at all.

If that doesn't do it, then I agree ... something is very wrong with your GPU.

Perhaps its the drivers and not the GPU, i.e., software instead of hardware. Looks like you're talking about updating the windows video drivers. Downgrade those and see if that fixes it.

I had a similar issue with some failed driver installs. Or just some broken non compatible drivers. Got resolved by reinstalling different drivers.

A SMC reset is not recommended to be reset multiple times, apple does not recommend this, PRAM/NVRAM is no problem though.

Can you cite a source on this? I have never heard of this and am skeptical of your post. Apple has had me reset the SMC multiple times on past MBPs and many have posted here they reset after a certain event to play games in Bootcamp.

I thought there was a post from Apple that recommended resetting the SMC anytime games in Bootcamp were getting low FPS. I can't find the source now so I could be wrong about this.

I am not saying that I'm right but I find it hard to believe that resetting the SMC could 'damage' your MBP. I would be interested in more information on this.

Not exactly saying they recommend not to reset multiple times but they do say this:

Intel-based Macs: Resetting the System Management Controller (SMC)

Note: It is possible that the SMC could encounter an issue that may cause unusual system behavior typically related to the symptoms described below. In some cases, resetting the SMC may be the only correct method to resolve the issue, however, an SMC reset should only be attempted after all other standard troubleshooting has been performed.

Turn the gpu off for a few seconds on device manager than turn it back on. ITs a glitch with the Nvidia drivers no matter what driver you have on Mac.
