Bad 3570K? + Temps

I've been messing around with voltage and whatnot and seem to be getting depressing results. I'm using an Asrock Extreme4 Z77 motherboard and a Hyper 212 EVO. First, I tried to undervolt it and the lowest I could go without it freezing up or crashing was 0.98v. Next I tried to OC at 4.2ghz and the lowest voltage possible was 1.21v. I'm relatively new to all of this so I'm not sure if my results are normal or not because I've read around that people can get to 0.9v at stock clocks, etc., etc.

Also, I was wondering if my temperatures were okay. For my OC of 4.2ghz with 1.21v, I am getting around 70C on Prime95 Small FFts.

EDIT: And another question. How come cpu-z reports a voltage of 1.128 even though in the UEFI my voltage is set to 1.21. Again sorry for the noob questions.

  1. Those temperatures are nothing to worry about.

    What are BIOS settings? Try to overclock with FIXED voltage!
  2. Yes, it's at fixed 1.21v. And I did a 4.2ghz overclock across all cores.
  3. Your voltage should jump to 1.21 when you do something like prime95.
  4. What's odder is that when I stop running Prime95 and go idle, it goes up to ~1.2v on cpu-z, but downclocks to 1.6ghz.

    You advocate fixed and mal and I advocate offset... :p
  6. What do you guys think? Is my CPU a bad sample? I have read about some people hitting 4.4ghz at stock voltage. And would I even need to use offset instead because I normally shut off my computer because with an SSD I don't mind booting up.

    I personally use offset, but fixed voltage is the 100% guarantee your OC will work. Plus, I think offset takes too much time, too much guessing and checking :whistle:

    Not every processor is the same! :non:

    Just because someone hits 4.4ghz at stock, doesn't mean yours will!

    My i5-2500K can hit 4.5ghz with 0.016V above stock voltage, but my i7-2600K can hit 4.5ghz with .2V above stock. See, I have a rig with a lucky chip and a rig with an "average" chip!

    Yeah, I do agree with that. :lol: It's definitely more difficult to get right.

    Offset is screwy too :??: If you don't get it right it sets your voltage WAY too high....but I guess you don't have a choice! :ange:

    That's why you get at least "-V" board..... :O

    No, unfortunately not, but I think I'd still do it anyway.

    Dunno, TBH I have no idea why people want to overclock these processors. :whistle: They are plenty fast.....

    That is true. :lol: I just OC because I can, lol.
  14. i used offset. pretty awesome.
    +.94 for 4.5GHz
    goes down to .95v when at 1.6ghz but boosts to 4.5 when needed :D
  15. Yea probably i got an average chip aswell because i need like 1.2 for 4.2ghz as well and im currently at 4.5ghz with 1.26 voltage this is the sweetspot for this proccesor anything more and you need over 1.3 volts not worth it IMO unless your trying to kill your cpu then yes lol
  16. Im new to overclocking aswell but ive got mine stable at 4.5ghz with OFFSET mode on and 1.200v..... temps dont go above 75c on prime on AIR
  17. Yeah I just double checked, its 1.21v fixed mode but when running prime95 cpu-z reports 1.128v, but when I stop running it jumps back up to 1.2

  18. Well, I'm messing around with the LLC, which has been causing the voltage drops under load. Should I leave this enabled or disabled?

    EDIT: Originally the LLC was set to Level 5, but I've moved it down to Level 2 and have been able to lower my voltage to 1.145 for 4.2ghz. When under load, CPU-z reports 1.12 now.
  19. Keep LLC around 2-3.

    Ive got mine on Ultra High on the asus sabertooth but im at 4.5ghz, is that right?
