I5-3570K Wont Pass 4.3Ghz

Here are my specs

GIGABYTE Z-77X-UD5H
I5-3570K
GTX670 OC SLI (Two of em')
850Watt PSU
128GB SSD
8GB 1600 KINGSTON RAM


I can OC to 4.1GHz with no overvoltage, with overvoltage i can easily reach 4.3GHz, if i do 4.4 or 4.5 hell ensues, BSOD's on the seconds I start Prime95 and all kinds of stuff. Any idea? I just OC'd via upping the multiplier.

  1. Whats your cooler?
  2. HYPER 212, heat is not a problem to be honest, had pretty nice temps when it DID work
  3. What voltage are you seeing with 4.3GHz? Try to manuelly set the voltage around 1.2+ and see if you can 4.4GHz. I try to keep my Intel® Core™ i5-3570K under 80c under load so I was sticking to 1.2v and 4.3GHz for a 24/7 overclock.

    The first OV I did was actually 1.35v (Might too much overvoltage be the problem)?
  5. This topic has been moved from the section CPU & Components to section Overclocking by Mousemonkey
  6. Oh there's an overclocking section? Sorry, didn't notice. So can anyone help me?
  7. 1.35v is way over what you need. Try to run 4.5GHz at around 1.23v and someone on the overclockering forum should be able to help you with more information if you need it.
  8. I just tried that, it wont even boot at 1.23, BSOD'd just as windows started at 1.31 and works fine (not stress testing) only at 1.34
  9. But -- now that I put it on 1.375, I think its pretty stable. Is that voltage dangerous / will reduce life span of CPU?

    EDIT: Damn, crashed after a few minutes of stress testing. Meh, back to 4.3 at 1.250v
  10. Hyper 212 is the cooler master cooler yea?? I had that on my i7 950, although the temps seemed low i still couldnt get it past 4.0ghz, so i bought the corsair h80 and got it upto 4.5ghz. Thats alot for a bloomfield processor. Yours being ivy should overclock much more than that, 4.6-4.8, im pretty sure its the cooler. What temps are you getting?? Hyper 212 is only a low to mid range cooler, the difference between that and a stock cooler is not that big. Learnt that from personal experience.
  11. It's not the cooler, it's the chip.
  12. Yeah, kinda figured out i got an average / less than average factory chip. But it can easily make 4.5 - 4.6 with almost 1.4v, my question is that safe?

    Monitor your temps using RealTemp and Hwmonitor..if it goes over 100c it will throttle itself.



    To be honest, few hours ago ive actually tried to increase the power limits, it were pretty stable. But the temps were pretty high, so Ill stay on 4.3 until I figure out a way for lower temps

    I applaud you for not taking this moment to bash an ivybridge chip.
