I have an EVGA 970 ACX 2.0 and since a long time ago I've been having problems with it's performance, it should be running at 1165Mhz, but it get stuck at 135 Mhz.
Using the CPU-Z I've tried reseting the BIOS and the Graphic Card starts running at 1165 Mhz but quickly goes down to 135Mhz and after that it doesn't go up again.
I've tried the Nvidia Control Pannel to maximum performance and nothing happens, I tried overclocking it but it just ignores the programs and it stays at 135Mhz no matter what I do.
I though it could be a power problem but I tried pluggin my friends MSI 970 and it worked perfectly, so now I'm completly lost about what it could be, I read that thread about the double Bios but it seems that mine doesn't have the switch for the double bios.
So I was wondering if what I could do since I can't buy a new graphic card and certainly I can't sell this one either.

Welcome to the Forum
 
Sometimes this happens to me as well if I Overclock it to high.
I reduce the Overclock a little and then save my profile in PX16 then re-start my PC and run or play the Game that locked it down to 135.

I got it stuck at 135Mhz at anytime, it doesn't go up with anything.
Do you mean reduce it lower than 1165Mhz?

Hmm, guess I can't post links yet since I've been hiding in the shadows and not posting, lol.

You need 11+ posts to link Or just add a few spaces when typing it in

Maybe setting the Bios back to the Default OEM Bios would be a good place to start.

 Yes, that's my card
 
Here is a screenshot, with GPU-z I can reboot my BIOS, and when I do this the fan goes up to 1165mhz but it quickly goes down and gets stuck again at 135mhz

When was the last time you updated your Motherboard Chipset Software and the Intel inf update?
Also run this at a DOS Prompt sfc /scannow make sure you run this a an administrator.
 

Sounds like you may be out of luck then.

How you tried flashing a different, possibly unlocked, VBIOS to your 970? I'm not an expert of GPU-Z codes, but it looks like you are hitting power limits when there is no way it really could be. A different *compatible* VBIOS might fix that.
