Is Non-K Overclocking Safe?

[DuelShott]

I have a I5-4590 non S, I have heard online you can overclock non S or K processors. Is it safe? Should I do it?

[i_build_nanosuits]

you can't with haswell.

[DuelShott]

@i_build_nanosuits I thought you could with haswell refresh.

[Leonard]

Not really and yes you can but with a "custom BIOS" which has now been tabooed by Intel.

[The Salt Is REAL]

You can overclock up to the turbo frequency on non-k CPU's but I'm not too sure about S CPU's.

 

But to answer your question, yes it is safe as long as you have a good enough cooler.

well, not really...you can try...you can sometimes force the CPU to run on the turbo clock on all cores but you have to disable all the power efficiency features....and you can try to move the baseclock to 103mhz or something....will get you a 150mhz overclock +/- but will trow a lot of stuff out of wack...consider your CPU has being non overclockeable what so ever is my advise unless you really know what you are doing.

@Leonard I don't think haswell refresh was affected by that Taboo. I could be wrong, wasn't it only Skylake?

[Lord_Karango17]

Well, considering there is very little difference between k and non k chips, you will be fine. They are just binned, where the worse ones get the overclocking disabled...

 

On my i7 3770 I'm able to increase the multiplier 3 stops above max turbo, so I can get all 4 cores to 4.1 ghz, unlike the stock 3.4ghz.

 

bclk overclocking is where it gets dangerous, and may cause issues with other parts of your system.

haswell won't let you move the multiplier at all.

Skylake is different, lot less stuff tied onto the CPU baseclock frequency....and they unlocked it through new bios...haswell is not like that, you can't really overclock locked haswell.

Yeah, I haven't messed with my i5 4460 too much yet in bios, but it only seemed to let me take the multiplier to the turbo clock speed, which it'll do by itself already, so it seemed kinda pointless...

They "tabooed" it for haswell and skylake but the skylake ones have vendors now providing custom MOBO BIOS which Intel has frowned upon. On haswell you can still do some BCLK increases but it is limited. 

 

You can get a custom haswell BIOS if you know where to look. 

[Conan1600]

you can achieve a modest overclock on a non k with blck . in general about 400mhz on  haswell. it will raise EVERYTHING so you can not go to high or you would risk KABOOM. 

[KemoKa]

You can, but only with the BCLK.

Now, in terms of silicon... there's no difference, they're the same kind of silicon, there's no reason why we couldn't overclock them through the roof if Intel didn't purposefully lock the chips.

I wish we had unlocked i3s... Those things would be monsters...

[thatguy321]

Yeah, just checked again, can take the multipier to the turbo clock speed and that's it. Not BCLK adjustment on my mobo, not that I'd probably mess with it anyways. 

 

Might try try setting all cores to turbo speed just to see if it makes any difference in benchmarks like Cinebench, just for shit and giggles, might squeeze out a few more points.
