this is my first overclocking and i already read intel gods thread,i overclocked my 4670 to 4.4ghz on auto voltages and it seems stable..the max temp is around 75c(aida64 stress test)i tried tweaking voltages manually but BSODs occurred..so i left the voltages 'AUTO'..i have heard that leaving auto voltages the CPU overheats.
i wanna know that is 75c is too hot for cpu since it is on AUTO voltages(cooler hyper 212 evo)and also i had to reduce the cache ratio to 35 to make it stable..otherwise i got BSODs..
