Problem overclocking 3570k to over 4.3ghz

[ltbenjamin]

Hello. Ive used oc genie 2 to overclock my i5-3570k to 4.3 ghz with everything on auto but the multiplier (43). In cpu-z it shows the core voltage between .98 and 1.00. Ive tried to go to 4.4 but my pc wont boot. Ive used auto voltage and also tried changing voltage to 1.15. Still no boot and it will have to be restarted several times to get it to revert to default bios clock settings. Any ideas? Am i doing something wrong? Ive read up on everything but it is confusing and i figured leaving everything on auto would automatically adjust for the multiplier. The core temps dont go over 55C on the core temp program while using prime 95.

Restart Over again & set Multiplier at 4.2ghz on Auto if you want or Change it to 4.3ghz at 1.250v & up!! Find it Stable 1.15v aint enough volts to run 4.3ghz!!! So set it at 4.2ghz on Auto or change it to 1.250v that what I needed for my Cpu I5 3570k!!!

Keep In Mind Ivy Bridge throttles at 105 C. If you want to play conservative and be safe, I'd advise keeping it under 90c!!! Also if you're using Air I wouldnt go past 1.35v you will need Water Cooling going past 1.35v depends on your Temps!!

So whats the avg needed voltage for 4.4? 1.275? I assume with my zalman air cooler 4.4 might be about the highest i should go to be perfectly safe?

Someone in another overclock post said to keep lowering the voltage until it wont boot, then bump it up one notch that way you dont get to much volts and unneccesary heat. Is this correct? I had the voltage at 1.225 and the core clock at 4.4 ghz and prime 95 had no errors and core temp read cored from 63 to 71C max. but then in guild wars it froze and said pc ran into a problem. So i bumped it to 1.230. Maybe its the graphics cards clock that had the error tho? I have a sapphire vapor-x 3gb 7970 set at 1200 clock and 1700 vram and +20% power and the vddc is at 1256 but i didnt change that setting.

4.4ghz I would Try 1.3v & Check for Stable with Prime95 see what Temps you get keep it under 90c kkk Max for cpu is 105c so i would keep it under 90c!!! If you're stable at 1.3v & you do some Game play & everything works Then Good ) Then Restart & remember what Voltage u had 1.3v so knocked off 5 points to make it 1.295v & run prime95 see if that stable!! always wanna make sure you're not using extra power on your cpu when it doesnt need it!!

 

[NightHawk87]

I hit 4.4ghz at 1.285 or 1.290 cant remember & I was 24/7 stable!! I'm at 4.8ghz with my Cpu I5 3570k ) with Voltage of 1.42v Max Temps I get is 88c

My 3570 is at 4.4 ghz and only using 1.23v and it could go lower i just was tired of rebooting. Temps dont get over 70C. One went 76C but they avg 70. No errors on prime 95. Maybe i should try for 4.5 ghz? I know my cpu will never get to prime 95 temps with just games.

 

[NightHawk87]

Nice so you got 4.4ghz at 1.23v?? if so Nice how long did you test for & did you do any Gaming?? & By the Way Yes you can Go Higher Keep it Under 90c ..... When you're Testing & everything seems Stable & Temps are Good & when you're done Testing & you Go into Gaming & if your Game Crash you're not Stable etc.

How long did you test for stability using prime95? Your games crash probably because your GPU overclocked is not stable.

Most people get 4.5 with 1.3125 and 4.6 with 1.325 (i got 1.35V for 4.83 with my I7 3770k but it need a 46 ratio as 48 X100 require 1.4+V to boot and heat too much...)

I would head to 4.6 if you have a mid range CPU cooler like a cooler master hyper 212 or somthing like that... Keep temps below 90 Celsius and you'll never have trouble with that

It's true but you still have to test for stability. Run prime95 blend test with round off checking enabled for at least 12 hours.

If his Game Crashes he is not Stable Etc. this has nothing to do with his card when he is trying to oc his cpu!! I mean he can take out his card & game will freeze or w/e that because he aint 24/7 stable!!

If your Overclock on your Card was FINE before you Overclock your CPU then its not that its your CPU its not 24/7 stable so bump it up 5 points & go into Gaming & you will notice & if Nothing Crashes your Stable

I should've commented more clear but I asked his stability testing with prime95 for the CPU since he didn't clarify how long it ran.

His 7970 is running at 1200MHz, clearly showing that the card is overclocked and he didn't clarify whether this was stable or not. Just because it could run certain games without crashing after a few hours doesn't mean it's stable. He'll need to test it with some stress programs like Furmark, or Kombustor or OCCT.

So, his game crashing could be either a result of unstable CPU or GPU overclocked or both.

He only needs to Test on Prime95 or w/e Program he uses to Test his Cpu for 6hrs 12hrs is just a Waste lol

I disagree (granted I'm more old fashioned), I would still run it for 12 hours. There are other people who even run it for 24 hours too, you know.

Ya we just gotta wait & hear how long he been running that CPU Testing for & I dought its his Card since he didnt have any Problems before when he just got Into Overclocking his CPU!! If your Game Crashes you're not 24/7 Stable!! Bump your Voltage up 5 points!!! If it was your Card does your Settings on your Overclock go back to Default when it Crashes or does it say Game stop Running?? If game stop Responding you're not Stable on CPU!!

ROFL You're more OLD Fashioned w/e that Means there buddy & 12hrs & 24hrs people are Insane haha just a Waste of Time!!! 6hrs is Good Enough & if nothing Crashes your 24/7 Stable Etc.

 

[ltbenjamin]

Hi guys. I updated drivers and now the game doesnt crash. I only tested prime 95 for about an hr. 24hrs! Aint nobody got time for dat! I will try 4.5 today and 6 hrs of prime95 and post back.

Sweet Deal man what is your Overclock 4.4ghz?? What is your Results?? & you're gonna try 4.5ghz Nice & ya just do bout 6hrs of Stress Testing 12hrs to 24hrs that just Insane no Need to do anything like that waste of time & if you was really that smart on Overclocking 6hrs plenty enough!! Always Remember if anything Crashes not Stable

Just thought I'd shared some overclocking guidelines.

 

[NightHawk87]

When Gaming Test BattleField 3 if you have it that Max out your Cpu & it will let you know if your Cpu is 24/7 Stable do bout 7hrs of Gaming on all your Games & if its stable bump your voltage +5 & you're good to go & watch your Temps Use Real Temp to Monitor all time! Let me know your Results

 

[NightHawk87]

Watch out if you Use Intel Burn Test that will Max the Temps out like Crazy prob over 90c+ so just letting you know! when using Prime95 or Aida64 you will get less Temps cause Intel Burn Test Maxes Everything!!

 

[ltbenjamin]

Should i use intelburn? How long do i use that for? If prime 95 temps are more than games will make your cpu, then why would i need intel burn? I probably could get 4.6 ghz and stay under 90C but i dont wanna push my cpu that hard. 4.5ghz is a pretty good boost from 3.4. I saw a bench that showed 4.5 gained 5-10 fps and 5ghz gained 10-15fps

 

[ltbenjamin]

And i use core temp. Is real temp better?
