It seems i cannot overclock my old GTX 650 2GB over +50 Mhz without surpassing the maximum core voltage Afterburner lets me have.
Everytime i get an unstability, lowering the Core Frequency solves it and my temps are very good (around 60 ºC on Heaven test).
If i could increase the Core Voltage over the +62 mV i am very sure i could get it stable with at least +100 MHz and 65~ 70ºC
Also, i know this isn't the question, but i cannot change my Power Level at all, it's grayed out and it has no values.
