I want more oc, but know nothing about voltages

post #1 of 22
Thread Starter 
Ive been running my cpu at 3.36ghz for ages, and its been fine, but thats as far as i could get it to go without changing the voltages. Since i upgraded my graphics card however, i feel the rest of my pc isnt doing it justice, so i want to start overclocking the cpu more heavilly.

Fsb is at 320, 325 is unstable. The ram doesnt like overclocking at all, the best oc ive had on it is .6 mhz, it doesnt like my motherboard much. i can turn the ram votages up, to the rated 2.2 from auto, but it makes it unstable. Im fine running the ram at 1066, i want to push the cpu more.

I tried looking at the cpu in cpuz to see what the voltage under burn test was, and it was about 1.25 (im on auto volts), so i tried 1.26, but it turned out to be about 1.22 in burn test and made it unstable.

How to i up the cpu voltage enough to allow me a bit more headroom with the fsb, without taking it too far? is it even possable to get more, or is 3.36ghz the limit.

I dont know your particular bios but usually there will be a setting near the cpu that says cpu voltage or whatever and will move up in small increments. like .125 is how fast mine moves up. there are all different names your board prob just has a wierd name. go into bios and either take pics for me to see or google all the things that look like it might be a voltage control.

I know where the voltage control setting is, but it is on auto and alows you to move up in 0.00625v interval. I dont know what i should set it to.

Just dont go ridiculously high you say on auto its 1.25v and when setting it to 1.26v in bios cpuz says 1.22v so try setting it it to 1.30v in the bios. thats well within the safe zone and then you can try and see what CPUz says and from there you you just keep upping the CPU speed a little, test for stability, if stable, up cpu speed more, if unstable, up voltage 0.00625v and then try again. Check Intels site, they will probably have info on the max safe volt your CPU can handle. just dont go above that, maybe 0.01v-0.02v above wouldnt hurt.

You will have to test on your own... overclock more the cpu little by little... in between each overclock step .... go testing running LinX(Don't forget to - run it as administrator) for more than 20 runs with the "All" button pressed ....... or IntelsBurnTest(IBT) testing 20 more than 20 runs at "Maximum" .... or Prime95 on Blend for more than 3 hours

If it passes any of them... then go higher little more...

Keep going on overclocking the CPU... but if it Reboots/BSOD then simply start increasing cpu voltage a little bit (do the testing process again).... keep going up overclocking until you definitely find you can not stable it anymore upping the voltage - which means you reached the wall.... so simply you would go back to the previous max stable overclocked setting you managed to achieve.

Now but you need to pay attention to the temps.. I have no clue whats the safe max on your chip

oic. Ok take it off auto and first set it to stock (+0) then see if you can boot. if not you up it by one click each time until it boots and runs prime/occt/etc stable for a while. I use 20 minutes when I am still trying to get to a higher oc. Then I go back in and up the cpu speed and test. if voltage bump is needed you up by one click again. Dont go above 1.5 is the standard number for most cpus and after a quick search for you dont go above this. Post a cpu-z ss of the main page running prime or oct so I can see the stressed numbers. Idle dont matter

did another quick search: for temps stay below 70 if possible

don't do 20 minutes (its not enough at all to say its stable) - pass more than 2 - 3 hours on those stressing apps *Prime95/OCCT

LinX & IBT is 20 ***RUNS/PASSES*** <- not minutes

I unlocked the fourth core on an Athlon II x3. The default voltage is supposed to be 1.375v, but when I set the BIOS vcore setting to auto, CPU-Z returns a voltage of 1.432 while running torture on Prime95. Even if i set the Vcore to 1.375v, CPU-Z still returns voltages ~1.42v. Is this okay? Should I trust the "Auto" vcore setting?

I use occt or prime so I wasnt talking about runs/passes in IBT. I mostly use OCCT tho for the graphs cuz then I can walk away and come back and know what happened

no I am saying I use 20 minutes to see if that clock is somewhat stable. If it lasts 20 minutes you can up the speed. Eventually you get to a point where you can last 10 seconds. Thats when I know to back down and find a stable clock. Once I find one that can last 20 minutes and its the speed I want I do a hour or 2 test watching temps. If temps are good I run something overnight to make sure its 24/7 stable.

I think I explained bad what I meant or you missunderstood me but wanted to clear up for the OP
