ASrock z77 extreme4/ i7 3770k OC

[nickwithtea]

Just did two 100% load tests with the cpu (i've already had it for a while) and left all settings for AUTO for regular use than OC use.. interesting that it clocks a little above when it's on the default settings

OC all auto with 39 multiplier: http://i.imgur.com/y91Uk.jpg

All core reset to 35 multiplier, then all core set to "auto" default: http://i.imgur.com/HoBwk.jpg

Just want to know if those volts are way too high for auto settings, I believe they are.

Also, the stock clock automatically goes to 3.7ghz, I wasn't aware of that until now. Actually when the PC first booted it went to 3.9 to do something then dropped down to 1.6ghz in idle

Anyway, I'm looking to keep it 24/7 at 3.9 or 4.2ghz (4.2 preferred)

So I'm thinking of setting load line calibration to level 5 (for lowest idle)

And Using an offset of -0.065v or -0.100v .... and I'm not sure if I should set an additional turbo voltage?

[nickwithtea]

I'm also very new to this, but I feel like the volts should be around 1.180-1.190~ for an OC of 4.2ghz, maybe even lower?

[nickwithtea]

oh and the idle is 1.096 v / 1.104v on stock settings

1.restore deafault settings.
2.increase clock
3.test stability
4.if stabel go to step to 2.
5 if unstable decrease clock or increse voltage
6. if target framerate or temp max is reached stop

Auto mainbord OC usually just burns Energy

[Tidefighter]

Oh forgot to mention if up voltage in the SMALLEST spossible steps.

and take your time

Ok, I'm running 4.2ghz at offset -0.080v
load line calibration level 5

prime95 crashed at -0.085v, however turning it down that 5 made it pass where it failed before.

It seemed very stable at -0.065v but I decreased the volts a bit.

Hitting 1.200v 100% load @ 4.2ghz / max temp on one core 3 77c

Going to play some games and see what happens, will increase volts by .005 if any errors are encountered, will also run prime95 overnight for like 6-8 hours to test stability.


I have my default clock settings saved as a profile on my bios, however like the screenshot shows the default would turn my 3.5ghz to 3.7ghz at max load, right now I'm running a higher clock with a less voltage than default.. soo seems pretty good :)

[nickwithtea]

A guide said the guy was hitting 1.120v at 4.2ghz... I guess he had a really good proc/better cooling?

[nickwithtea]

it's the hyper 212 evo+

Ok, had a game crash after about an hour of playing. Increased it to -0.075v, going to keep playing until it seems fine for long periods of use. Also going to run stress test tonight.

If it fails anything I think I'll go back to -0.065v, where it seemed pretty stable.

[nickwithtea]

Ok well, I'm not entirely sure if the crash at 75 was related to the OC, since the game I tested does crash sometimes. However I believe my pc may have rebooted during another stress test, so I lowered it to 65 like I said and it passed 2 hours of stress testing, I'll begin general use from here on, and begin to raise the volt .010 if I notice anything funky. However I believe I'm stable at I think it was 1.216 volts @ 4.2ghz, with a max temp hitting 79c, and the average around 75~+C

Assuming I don't actually have anything that will hit max load, and that my case side fans weren't on, I should be fine. Shouldn't need to up this for a while to come :)

[nickwithtea]

Seems to be doing well, did 2 hours of stress testing with no errors seen and been playing games fine!

at -0.065v @ 4.2ghz :))

temp in what I think was a very cpu heavy game seemed to be 55c on one of the cores and 53c on the others, seems pretty good !

[bloodraven43]

thats a good temp on air...if you get a liquid cooling device...you can oc higher and your temps would be in the 30 s. your temps now are what they should be under heavy load on air.glad you sorted it out.

Your turbo speed is 3.9 GHz and that's what it probably always runs under full load on normal circumstances. I know that my CPU is a Nehalem i7 and though the official specs say 3.06 GHz, it always runs at 3.2 GHz when gaming and video rendering. I don't know why it does that, but I guess it was a goof-up on Intel's marketing procedures saying that it is a 3.06 GHz CPU when it is a true 3.2 GHz CPU. I don't know how that works on an Ivy Bridge CPU, but that's like something you may be experiencing.

[bloodraven43]

works the same, turbo on my ivy 1-7 3770k is 3.9mhz...mines overclocked to 4.6 mhz though...lol

[nickwithtea]

Yeah surprisingly it only seemed to speed itself up to 3.7ghz under max load, had no idea. Says it's 3.5, but always running at 3.7

Anyway still running great @ 4.2

For now I can't imagine needing to go higher for a long time. And as games come to use more cores my performance should pretty much just increase. As for going to a watercooler.. I'd love to but the frustration of taking out the motherboard, removing the cooler, then putting another one.. and if I ever even did that I'd might as well get a new case too lol... all so frustrating.. id probably pay someone $50 to do it for me.

Anyway, I got it all figured out, google and some youtube did me well :)

do you use Intel Speedstep?

i have mine enabled as id rather not run @ 4450 24/7

[nickwithtea]

I'm pretty sure that's on, but I'm using load line calibration level 5 and offset -0.065v

So when my pc is idle it clocks down to about 1~ volt and 1.6ghz

when something launches it goes to 4.2ghz @ 1.216v or so i've noticed
