Hello guys, (at the beginning sorry for my english language) today i open CPU-Z cause i want to overclock my G3258 and I noticed a voltage is up 1.744 V, i think it isn't normall. What shall i do now?
Now you test. Use something like Intel XTU (a stress test) to test the overclock stability.
Start by upping the multiplier and then testing.
If it passes, up the multiplier again.
If it fails, up the vCore and test again.
Go until your temps are approaching 85°C or vCore is approaching 1.4V.
