V droop/General OC questions

Hello forum. Today i decided to be a man and disable OC genie and do my own manual overclock on my 3570k. I landed on 4.4Ghz at 1.2 Volts. Im currently running prime 95 as we speak :P however, CPUZ shows my voltage as 1.3-1.45 volts although i set it to 1.2 in the UEFI. I did some research and came across V droop. What i want to know is first of all is my frequency to voltage ratio good? should i try turning the voltage down? And second is V droop really a bad thing? I mean more voltage shortens the life span of the CPU and apparently from what i read the CPUZ voltage is the correct one so by running at a lower voltage than i set in my UEFI and still maintaining a stable OC isn't that a good thing? Thanks

gaaah i made a mistake CPU Z is showing my voltage as 1.13-1.14 volts not 1.3-1.4 srry

Yes 1.14 for 4.4 is good. If you can swing 45 with 1.2Vcore you really do have a chip worth pushing :D

Vdroop is kind of bad, more lame than bad. Turn the load line calibration up to about 50-75%, set your Vcore to 1.15 and see how stable your board is. The voltage shouldn't move at all with 75% LLC.

You can go all the way up to 1.55Vcore, run that everyday and your chip will still be working when you replace it. There are people running 1.7V everyday with no problems.

thx for the help and also do you know where LLC is in click bios 2? i have an msi z77a g45 and i tried finding LLC earlier but couldn't find it. I did find V droop offset percentage though would putting that at 50-75% be good or are they not the same thing

Actually you will f*ck up any ivy bridge chip really bad with these voltages! With any air/closed loop cooling you will get nowhere near acceptable temperatures. Maybe the temps would be ok with a custom loop but I don't think so.

I suggest watching your temps and not letting the core temp go over 75C in p95. If it does back up your overclock a bit. My personal voltage limit for now is 1.25V...

Yeah that's it. Since its the g45, set it 100%.

I say keep P95 temps below 85C. He has a decent chip, he's going to be about 4.6 before he hits 75C in Prime, as long as he doesn't live in Arizona.

Yes I guess 85C would be fine too. As long as it doesn't run at this temp 24/7 (which it won't playing games etc)

I live in north Vancouver near Linus kinda lol. always cold here. my temps with p95 never went over 67. I'm gonna set the v droop offset to 100% and go fro 4.5 with 1.2 now! thanks allot for your help guys!

one more question, since i just validated my 4.4 OC with 24hours of small FFT should i give my cpu a break before running it for 24hours again or just go for another 24hours at 4.5

                                                                                                                                                                | 5820k+EK supremacy nickel+acetal white 4.5Ghz | X99 Deluxe | Enthoo Luxe | 2x gtx780+komod NV full cover block | Corsair AX1200i | WD blue 500gb |

For validation you only need a 15 minute small FFT run when testing OCs, or even a simple HyperPi run :P

Keep pushing your OC and validating. After you reach your temperature limit, run a 12-24hr Blend test.

Don't be afraid to go hard with the Vcore, just keep the temps nice. Well be a little scared, your board isn't exactly top tier :L

i just stopped the test today after 24 hours and on core 2 in the box I read worker stopped fatal hardware error and it told me to consult some file. Computer didn't crash/freeze etc and all other cores kept going though. Is my OC unstable? core 2 still runs fine and my pc is working no problems so i don't really get what the fatal hardware error is

Failed after 24 hours? Give it one more little bump of Vcore and don't bother stressing, you're good.

All that means is core 2 didn't finish or made a mistake, so add something like 0.005v-0.010v.

GZ on the OC!

failed after 22hours :P Thanks!
