Need help overclocking a G3258

[PepperBurst]

So I got a Maximus VI Hero and a G3258 for a nice deal. So everything is up and running and I kind of need help on how to overclock this CPU. All the How-to's and what not. Any ideas?

don't touch the bus speed

search for reasonable overclocks on stock for the Pentium then go to then below

up the multiplier slowly, then voltage on you cant oc more on stock(offset mode)

Everyone has their own method. Here's how I do it:

 

Start with a core voltage of 1.2v and see how high you can push the clock speed with that. 

From there, add 0.01-0.02v increments and see how high you can push the clock speed until ~1.3-1.35v (whichever is most comfortable to you).

Make sure to mark down your results and you should be able to see a curve of diminishing returns. 

Make sure temps stay below ~80-90c at load and you can determine where your most comfortable oc is from the curve.

I also recommend uping your fan curve a bit if you are the type who likes their components cool

First things first, find your stock VID. Best method to find out your stock VID would be to clear the cmos and check your bios hardware status. For example: my stock VID was 1.060V. If yours is under 1.1V, manually set your Vcore to 1.1V, along with your Cache voltage to 1.1V. Change the voltage settings from adaptive to override if you have any, and start with a modest multiplier change. Most G3258's are stable to 3.7-3.8 on 1.1V, so you can start at x36 core and work your way up. Do a stress test, like LinX for 10-15 minutes. If its stable, bump it up to x 37, and repeat until unstable.

 

When its unstable, throw a little more voltage at it (small, slight increases). Also make sure you manually set your ram timings, and make sure you set your core and cache multi to x32 in the bios, never leave anything on auto for OCing unless advised otherwise.

 

After a while, you will need to adjust your Vrin and LLC settings, but you should be able to net a pretty decent OC without going into detail about those two settings.

EDIT: I forgot to mention that using Intel's Extreme Tuning Utility is far easier than constantly rebooting to BIOS to change core multiplier. Also, leave the cache multiplier at x32. There have been no proof that changing the cache ratio will net any performance gains, atleast as far as anyone can currently perceive.

or instead of testing it everytime, go till you feel iffy, notch it down .1 or .2 then test

for a bit of less time taken

So far I can't seem to download IETU for some reason

I'm currently using stock cooler and at it's stock speed it's only maxing 50 degrees at 100% load. What actual safe zone in temperature do you consider once I turn up this thing?

Keep load temps below 80-90c.
