Overclocked i3 3220

[Mug3r]

So its been asked to death Can I OC X non-k CPU, well I've gone and done it.... I just BCLK clocked my i3 3220 to 4.02 GHz(3.30GHz base) and its held stable for the last 5mins. I'm still scared as all hell that it will melt right here and now or worse my GPU will explode but I did it for science, now can someone tell me, should I tone it down all is stable no unusual temps etc,(76C on CPU, 30C GPU I have a 6 fan well-ventilated case so I can assume my VRM and RAM wont melt. Should I keep this on for the meme or tone it back down. Scared as all hell right now.

UPDATE: While running Cinebench the CPU skyrocketed to a max of 107C I think this is a clear sign for me to abort the mission and go back to my i5 6600k which is meant to be OCed and has a decent Cooler on it. I'm a bit disappointed though was hoping to have a little fun to see how far I could push a Budget PC. Fun's over pack it up.

In closing I suppose despite a short bit of success in the end its too impractical to try anything on a budget CPU(especially considering this was only possible because its winter here and I've dropped the ambient temps to 20C and have both side panels off.

Correct me if Im wrong here, but 76c on the CPU seems a bit high?

Is this idle or under load?

Also, do you NEED to overclock? Or are you doing it for fun?

UPDATE:

Core i3-3220
Idle Temp
28 to 35°C
Normal Temp
50 to 60°C

Max Temp
65°C

temps are fine, have you done it on a board that de-couples the PCI-E and SATA buses? or are they running OC'd as well (a very very bad idea if they are). you'll want at least 3-4 hours stable under test loads before it's stable for use.

I absolutely don't NEED this but I'm doing it for science, 76C is pretty standard for my PC(standard intel cooler) the temps have since dropped to around 60C now(I opened my window to let the cool winter breeze in.

not certain, but on my sata bus all I have is a 64GB SSD and Pci-e I have an underclocked R9 280, the temps are staying stable for both devices.(using a intel DH77KC board)

MERGED QUESTION
Question from Mug3r : "Overclocked i3 3220"

So I've just BCLK OCed my i3 3220, to 4.02GHz its been stable at decent temps(70C core) for the last 5-7mins nothing wrong elsewhere HWMonitor tells me all is well everywhere else I'm not sure whether or not to keep it OCed for the sake of science and a good laugh or to tone it down before I irreparably melt something, Advice?

don't duplicate post

Yeah sorry, I thought this one didn't go through for some reason(internet has fits)

The temps on those devices won't change because of this, but their speed and therefore stability might. On pre BCLK OCing i processors (post 1st gen), the Bclk could only go to about 103-105 before the other peripherals attached to it became unstable.

I'm not even sure why i'm asking this, i'm 99% sure that the 3220 mobo's do not decouple the other peripherals from the bclk speed, it's only the last (2?) generations that do this.

Are there even any 7 series motherboards with that functionality? I didn't think that was possible.

Strange, Windows isn't picking up the change my BIOS clearly shows 4.02 on CPU but windows says its clocked at 3.30

Windows doesn't generally read the actual clocks, 3.3 GHz is part of the "name" of the CPU as far as Windows is concerned.

But then when I check in HW Monitor it also states the max as 3292 MHz

 

[Mug3r]

So I think I'll let it run for 3 hours or so, under some mixed use(chrome browsing, word processing, Video playback, a cinebench run or two and some light gaming) Will report on the results

Check cpuz.

 

[Mug3r]

Check cpuz.

I don't know what I didn't do that in the first place, probably just too used to using HW for everything, Okay here goes.

Hmm odd

this is during a cinebench run so I knwo the CPU should be at max use

So you are definitely not oced. It would have been impossible to be at 121 bclk when everyone else can hardly get to 105.

 

[13thmonkey]

^ that was my thought, you'd have had GPU and storage subsystem issues past 105-106. And 3 hours of light use is pointless, 3hrs of prime is the start of a good test.

I get the feeling some kind of safety restriction was in place, that dialed it back to 100, although on BIOS screen it did say that 121 was the active setting and I did see marked temperature gains during use

 

[k1114]

Some mobos will let you change settings but it actually doesn't do anything because it's locked. There is no reason temps should have even changed when nothing changed. You are still at stock speed.

Then I'm really confused as to why my temps sky rocketed, I was sitting at an average off 100C according to HW monitor on the CPU whereas now after undoing it all I'm back to 45-53C

 

[13thmonkey]

was't a side effect of this kind of OC on skylake the temp sensing stopping, perhaps it just breaks temp sensing?

This is Sandy Bridge and temps reacted realistically to usage so I don't really doubt the results.
