I7 3770k 4.5Ghz Overclocking

post #1 of 11
Thread Starter 
I have some questions and problems i am having regarding the voltage. I have been stable running intel burn test at 1.165 at 4.5 before doing all the changes in the bios. After doing the tweaks i had to push the voltage to 1.175 to run Intel extreme tuning utlity it ran fine for 5 hours. Then i started to run prime for 24 hours, for that i had to push the voltage to 1.190 to run it for 24 hours. Now i am having issues with games like bf3 in some maps it does a heavy lag. I have checked temps fine with cpu on load 45 and gpu's are fine as well. I am pretty much trying to figure out what is my stable voltage so i can do a offset voltage. I am not sure exactly on what LLC i need to be at also, please advise.

Not sure what your question is. No one knows what your stable voltage is, only you can find that out. Just keep doing what you have been doing. Start at a clock you want to be at, and go up from there. You can start from 1.2v, and go up. Don't go past 1.52, or 1.45 for safety. Most 3770k can do 4.5ghz at 1.25v, if you can get it to be stable below 1.25, then good for you.

Your settings seem fine, Ultra is good for LLC.

As for the bf3 lag, that could be anything. Does it happen in other games? Could be your ram also, make sure that is fully stable before you start oc the cpu.

I dont have an Asus board but from what i can tell everything looks setup correctly. At least with ASrock boards you do not need to have internal PLL voltage enabled for a 45 multi. You also shouldn't have to adjust PLL voltage so this can remain on auto.

I would set you offset to a +0.005 then try to boot into windows. Then let me know what your Idle & full load vcore is in CPU-z.

Did you setup your ram w/ XMP profile?

I would use Prime 95 over intel burn test when stressing the CPU.

I have changed all the power settings to auto, i have changed ram voltage to 1.5500. I can go ahead and put the pll voltage to auto then. Also, i know when playing bf3 when tabbing it takes a while for the scoreboard to come up i wonder if it has to do with voltage? I am using manual not xmp profle in the bios.

I had ran prime 95 before overclocking with default bios settings, it passed fine.

I hit 4.5GHz stable with 1.12v; what are your temperatures like?

You can try bumping the pll voltage to 1.8v. It will give you some stability at the cost of a little heat.

1.224 idle on desktop after + 0.005 to the voltage, i went ahead and set the PLL to Auto. Load its going from 1.240 to 1.248 when running prime 95.

Temps are around 26 to 27 on idle and on load its 45 to 50.

Wow that's a really high idle voltage w/ a +0.005 offset. You will probably have to use fixed voltage on that CPU
