Tried and checked everything.Overclocking gives me the same performance no matter what I doDid you check to see if your GPU is actually running at a higher frequency while gaming?
I'm guessing that you're at or near the power limit even at stock clocks, so increasing clocks further just makes it power throttle harder. Increase power limit and try undervolting a bit. That should give you some power headroom to possibly increase the frequency.
Okay so I tired undervolting my gpu and it works.The question now is how far can I go.Log your core frequency and voltage as well as GPU-only power draw with GPUz while you're gaming under both settings (stock and OC). Compare the two scenarios for each statistic.
You're going to have to get away from "Auto" voltage to give yourself more power/voltage budget. Then you'll be able to OC and maintain the clockspeed you set. Set "Frequency" to "Dynamic" and "Voltage" to "Manual" in AMD WattMan.
Have a read through this thread where I explained the process to someone else, along with Freq/Voltage targets.
