I5 3570K overclock

I'm trying to stabalize a 4.2ghz overclock for an i5 3570k.

All I did was, set multiplier for my ram @ 21.33 ~ its a 2133mhz ram

Then set the Core clock and each individual turbo cores to 4.2ghz manually

I put internal PLL as auto

Kept Vcore @ auto

LLC on

everything else is set to automatic or default.

I ran a little stress test, 0.950 ~ 1.24K stable @ 4.2ghz @ 55C max stress. Did I do this correctly/properly?

  1. Don't OC your ram as there is very little point and don't use auto vcore.

    Use offset mode and slowly work out what is th3e lowest stable for you.
  2. ^ The ram is clocked @ 2133mhz, its not like I'm ocing it, if anything 1600mhz would be downclocking it am i right?

    Also, I think everything is already in offset mode. For Gigabyte mobos, theres no way to customize the LLC (for my board at least.) only two values i can type in there is either Standard or Auto.
  3. Can you not set offset value?

    Correct, unless I'm not figuring out the values here. I know there is a way to disable, but so far no luck finding anything on google regarding my specific board.
  5. ^ actually forget that, I got into the specific LLC etc...all the voltage settings etc

    Pretty much I kept LLC @ LOW profile and phase control @ balance. I couldnt mess with the voltages too much, too littler, bios would freeze up, too much and the voltage would get to 1.3V.

    Right now, my i5 3570K sits @ 4.2ghz with max 1.28V on 100 percent load using cinebench. CE1, CS3/S6 are all enabled, and haven't really messed with anything else after that (kept everything auto). Also for the V-Core my mobo is set @ 1.190V, if I try messing with this, my computer won't start, bios freezes up, and I need to clear the CMOS. (The v-core is responsible for sending current into my cpu correct?)

    I probably don't have the best mobo/CPU combination...and my Chip definitely doesn't have the OC potential as some of the other i5 3570K (made in malaysia anything to do with it? lol)

    So with all this said, my processor sits @ 4.2ghz with VDID @ 0.95~1.28V....Temps are all under 50C. Anything wrong with this, or should I really investigate in offsetting values for this specific board to get lower max Vid?
  6. 55C is a safe temp, just make sure you've run prime95 (or whatever stress-testing program you're using) for a decent amount of time, the suggested time is 8 hours+.

    You can get a better temp if you manually change the voltage, auto vcore tends to give it more voltage than needed hence getting a higher temperature.
  7. ^ true, but is 1.28V @ 100 percent max alright? I know @ that voltage, I could hit 4.4ghz maybeeeeeeee 4.5ghz but thats a big maybe considering i didn't get the chip lotto with this one, but I'm happy @ 4.2ghz.
  8. A lot of people seem to get around 4.5ghz on 1.3 vcore so your perfectly safe especially in temps
  9. Hey, a friend of mine need help to overclock. He has gigabyte sniper G1 MTAX motherboard with a i5 3570k.


    We have followed youtube links and tutorials, the system freezes on windows loading screen or even windows startup repair tool...


    Target speed=4500mhz
    Voltage 1,350v
    PLL voltage 1,650

    etc, etc, if you need a screenshot just ask.

    Can anyone help us out here? Do we need to lower the clocks to make it work or what?
  10. That is very high voltage. Lower the voltage and the speed. Also make your own thread if you need peoples help.

    Thats WAYYY to much Voltage on the i5. 4.5ghz is achieved between 1.21-1.25v on most chips.

    I have my 3570k at 4.6 with 1.23v never goes over 70c under load for hours. Extreme setting on both LLC and Phase Control.

    I have the Maximus V Formula Asus ROG board, Cooler Master HAF 932 Advanced case and Xigmatek Dark Knight II Cooler

    1.35v jsut to get 4.5Ghz? Thats insane. Either that's a really bad chip, or someone dosent know what their doing.

  14. The Voltage you are running does seem high but everything I have read said that it comes down to the draw of the CPU. With that stated I am currently running 4.4 on my i5-357k with asrock extreme 4 mobo but my offset is only set too .010. @ 100% load my vcore maxes at about 1.1 - 1.05. What you should always do first is test the CPU by lowering the voltage as low as possible till the computer wont boot anymore and you have your baseline. You can compare that voltage vs others to see if you really did just get a crappy pick or if you are not doing something right.

    **Update**
    I just messed around with everything a little more to get some more accurate numbers hoping they will help you out a little.
    I currently have my voltage set on my Asrock Z77 Extreme 4 to Auto and during a Prime95 test I am maxing at 1.186 during the test. At rest I am getting .836.

    I hope this helps some
