Hi, I am running my PC at 4.2GHz no problem right now. I want to get up to 4.3GHz, but I don't want to touch the voltage because I'm not that experience in overclocking. Would I be able to go with 4.3GHz, at stock voltage, and still have a stable system? If not, what would be a safe voltage to have everything running well? Thank you.

Specs:
Intel i5 3570k @4.2Ghz
ASRock Z77 Pro3 Mobo
8GB DDR3 RAM @1600MHz
Corsair GS700 PSU
PNY GTX 560
Corsair H60 Water Cooler

Ah I dont think you can Cause I try to do it wasnt Stable!! But you can hit 4.2ghz on auto Voltage!!

Ivy Bridge throttles at 105 C. If you want to play conservative and be safe, I'd advise keeping it under 90 C... The max Voltage to go is 1.35v to 1.40v I would keep it under 1.3v but will be ok if you go over!! I'm at 4.6ghz at 1.344v on Water!!! On Air hyper Evo 212 I got at 4.4ghz with 1.295v..... What are you trying to get 4.3ghz or higher??

If you wanna hit 4.3ghz start at 1.250v if its stable go down 5 points each time till its stable!! Reason for that is cause you wanna make sure you're not using alot of Power that you're not using for the Cpu!! If it Crashes bump it up 5 points everytime & find it Stable!!

Use Programs for Testing...... Aida64 or Prime95 use Cpu-z to Watch Core Voltage go up & down see how much its using!!! & Use RealTemp to Monitor Temps while you're testing!!

If you find where you wanna hit & you do Testing for over 6hrs to see if you're stable or not & USE Program Intel Burn Test <<<< This will see if your System is Stable at the End!!

I'm just trying to go up to 4.3GHz. Right now I'm at 4.2GHz at stock voltage and have no stability issues. What would be a good voltage for 4.3?

I also have a Coolermaster 212Evo and got to 4.0ghz on stock voltage on a 3770k no problem. Don't want to go any higher yet. If you read up well on overclocking that cpu, you will find safe voltages that you can run at. I think 4.3 on stock voltages is pushing it and 4.2 is pretty damn good. Make sure you load up all four cores for a while to make sure its stable and watch the temps carefully.

oh ya ok set Cpu Clock Ratio to 4.3ghz & Disable Turbo speed & Speed Spectrum!!! Leave Base Clock at 100mhz!!!!! Go find Cpu Vcore in your Bios & lets Try 1.250v

& Save the work & lets see if Windows Comes up if it does good!!! Now Run Cpu-z & RealTemp & Use Prime95.... let it Stress CPu for bout 2 to 3hrs if it doesnt Crash or anything!!! Then you're good to go if anything Crashes or you get Errors you're not Stable!!! If that Happends Bump Voltage up till Nothing Crashes!!!

Remember Ivy Bridge throttles at 105 C. If you want to play conservative and be safe, I'd advise keeping it under 90 C... If it goes over 80 its Total not a Bad thing!! but Keep it under 90c!!

Since you Got Water Cooler I'm sure you can hit 4.4ghz or 4.5ghz!! Ill be Glad to Help you out

Well idk lol you can give it a Try & make Sure Temp stays under 90c.... If you want start out at 4.4ghz & stat out at 1.250v if that doesnt work or boot up try 1.260v!! If Either of these work keep bumping it up 5 points like 1.260v to 1.265v or if you want try 10 points go from 1.260 to 1.270v!!! I always start 10 points up cause If it Works & Everything I try to bring down voltage knock off 5 points & if it doesnt work then you will have to bump it back to where it was Stable when you tested it out & Everything!! You wanna make sure you're not applying to much Voltage!! Ill be around & will be able to help you!!

Oh ya or you can sometimes use Overclock Program that will work sometimes but your Base Clock will Change & you dont want that to happend!!! Its better off using the Real Oc in your bios Changing everything yourself!!

What are you Testing it with & are you Monitoring all that Stuff I listed above?? What are your Max Temps for bout 1hr of Testing?? on all your Cores on RealTemp Program?

Dang 66c that is Good Good lol & ight man just making sure idk!! & you're at 4.4ghz right?? what is the Max Voltage on Core Voltage?? Did you Overclock in Bios yourself or did you use Program to overclock for you?? If you're at 4.4ghz & only got 66c man you can prob Go Higher lol

Its not a program. I was wrong. Its like a auto OC setting in the BIOS. Its at 1.2 Volts. And I probably will go higher, I never knew this little cooler was so capable.

oh ya hmm never seen a auto OC in bios but still that good man 4.4ghz & Max temps was only 66c?? how long have you tested it for?? & You can probably get 4.5 or 4.6ghz depends on the Temps!! Gotta Stress Test your Cpu for bout 8hrs I would say!!

& Another thing take out your Graphic card when Overclocking so that why if anything Freezes up... You would have to Clear the Cmos on mobo to Reset everything if anything acts Weird or Freezes on you!!! Reason why to take out Graphic card is to be able to Clean Cmos if needed & Run Games without Graphic card & put it on Low Settings all Games so you can Play off your Cpu HD4000!!! If any Games Crashes During anytime then you're not Stable & or if anything else Crashes Not Stable Etc.

You want the Cpu to stay under 90c make sure its up in the 80c if you go higher on Oc!! If you Game like on Bf3 temps will be up in the 60 or 70c!! This Chip is for the Win lol I got mine at 4.8ghz at 1.360v but went back down to 4.5ghz cause that good enough for me!!

Yea, gotta love that. 4.8ghz on Ivy is equiv to about 5.5ghz on Sandy performance wise.

I haven't pushed my chip to its max. I dont see the point as my almost 4.6ghz is already overkill for anything I do. I bet I could get this chip to 5ghz seeing that its a"mint" sample. A few posters on other sites cant get 4.5ghz without heavy tinkering and 1.25-1.27v

1.28v? Shows how much variance there is chip per chip :( 

To go from 4.57-4.6 on mine for some reason required me to go from 1.21v to 1.24v. Im sure if I fine tune the phases and other voltages ect I could whittle it down to 1.23v on the core for so for a stable 4.6 27/4

saw more overall "system" performance increase when I tweaked the RAM and BCLK up, while keeping a 45x multi and a low 1.21v as opposed to just going straight to 4.6@ 1.24v and leaving BCLK stock and RAM at the default XMP profile.

Sorry bout Late Reply that Awesome dude you can Go Alot Higher then 4.5ghz since your Temps are only 64c :D  I myself just Purchase a Corsair H100i Water Cooler & I'm now at 4.9ghz with Voltage of 1.45v LLC Turbo & Temps are bout 88c 12hrs stress Testing Prime95 :)  I'm pretty Happy where i'm at now lol I couldnt get 5ghz cause vcore was like 1.5+ & it was Total Unstable temps was over 90+ so I left it at 4.9ghz & happy :na:

Sorry for the Necro post. But I was always leary about pushing the Vcore too high. Whats the estimated life span of these IB chips above 1.3v or keeping under say 1.4v? If I can get a good 3 years out of the chip IDC.

Or 2 more years to be exact. Cause then I'm upgrading whole system to Intel Skylake, DD4 ram and Nvidia Maxwell GTX 970 sli more then likely.

I am running my 3770K now at 4.2 at stock voltage fully stable under h2o. 4.5ghz is fine too with a small bump in voltage. If you are worried about your chip, just leave it at 4.2ghz as you won't get much more performance going up a notch.

If you dont mind my asking, why are you water cooling a stock i7? of course its going to be fully stable(unless im reading this wrong? If so pardon the ignorance). I can take my 3570k up to 4.4ghz on stock voltage, but I bought a K series CPU for the sole reason to push it. im air cooling it pretty chilly at 1.31v and 4.8Ghz, though I do have a mint chip according to other sites.

Although its at the stock voltage, the higher clock speed makes it run hotter. I also run Cooler Master Hyper 212 EVOs on the workstations I sell and they are excellent coolers (they run stock clocked Xeons, but they are whisper quiet, hence the upgrade).
