I want to overclock my CPU. Currently without overclocking it, I am getting idle temps from 34 to 36 degrees celcius and when full load its around 42 to 44 degrees celcius
I have undervolted my CPU to 1.2875 from 1.36. My case temps are from 29 degrees to 34 degrees celcius.
I want to overclock my CPU now atleast to 3.8 to 4.0 ghz. Please help me out. I want to know how much should be my voltage for overclocking it and what are the same idle and load temps after the overclock.
Its all a matter of testing to determine the volts needed. to get that high of a clock it depends on the quality of the chip you purchased, quality of the mobo and power supply. up the multiplyer untill it won't boot. then lower it 1 and run a test with prime 95 or intel burntest. if it fails you may need to up the volts. keep an eye on your temps though and don't let them exceed 60C. also don't go past 1.4V on the core. use cpuz tools to watch volts and temps.
Start to overclock in little steps, maybe you can hit the 3.6GHz stable at stock voltage but for those speed that you want the CPU Voltage need rise, don't go above 1.5V and 55ºC and you can have problems.
saint19 - thanks for the reply. There is one last question. I have my NB and HT at auto default settings. I know that I am stable with the multiplier overclock. My question to you is, is it mandatory to overclock even the NB and HT Link. I mean i don't see any reason for overclocking them but was just curious to know after seeing many people overclock them manually.
and kingmizu -
I have set the multiplier to 20 and have my Hyper 212 plus fan settings on 50% minimum and 100 % when it reaches 50 degrees. The voltage I used was 1.40
and I also underclocked my CPU to 3.8 ghz from 4.0 ghz. The reason why I did that is because I am not getting any notable difference in FPS except 2 to 3 fps (hardly) compared to 3.8 ghz and also the windows experience index shows the score as 7.5 itself for both 3.8 and 4.0 ghz.
So in order to be on a safer side, I underclocked my cpu to 3.8 ghz so that the temps stay better. at 4.0 ghz the voltage set was 1.40 and now I have set it to 1.3375.
So temps don't cross 48 degrees at full load Prime95 for 2 hours.
Is it ok to leave the CPU at 3.8 ghz because I dont see my CPU bottlenecking a single GTX 560 Ti. I will probably overclock it further to 4.0 ghz when I get another 560 TI for SLI.
Is it ok to leave the CPU at 3.8. What do you suggest.
