Hello all 
First of all i am new to the forum and i am not so experienced with overclocking but a friend of mine told me that there are safe standard low values i can set in msi after burner so that I can overclock my gpu he said 500 and 125 i dont remember i think 500 to set to memory clock and 125 to core clock or the opposite without changing core voltage,temp limit and power limit(which is 100% always).I dont remember exactly sorry its been a long time since i tried this,but anyway.
So,when I put these values I see an increase in GPU(more MHZ) but when i run benchmark or playing games i do not have a better performance, I would say that I may have a worse performance so i guess its not working.
Am I doing something wrong? Is there something else I have to do?
Τhanks in advance, please someone help me.
