Hello, I just finished my first OC on my gpu tonight. I am running a 5070ti and was able to be stable at +475mhz on core and +3000mhz on memory. After I finished OC I moved onto undervolt it, for the first time, I am very new to this stuff. I was following a guide on YouTube, found my top speed at 3300mhz / 1.035v, adjusted that down to 1v and was stable. I then adjusted it down to .95v and immediately my pc froze after applying that. I had to hold the power button down on my PC to restart. After restarting I have applied my OC profile that was stable, however my core clock speed is not going over 2600mhz now. Memory speed still increases by the 3000mhz like I change. When I reset my OC profile to default values, my core clock speed is then about 2100mhz. It is like my gpu is functioning off of some new low speed??? I am lost as what to do.
 
So I did do a reinstall of my driver and MSIafterburner and neither of those fixed it. I was able to fix it another way tho, although I have no idea why. I went into MSIafterburner and put my oc to +700mhz and noticed that it brought my core clock to 2800mhz, I then increased it again to +900mhz causing my pc to crash and had to do hard restart. After boot I checked and everything was functioning as before, I have decided I am not going to mess with under volting now.
