Overclocking with the asus H81

[wailharas72]

Hey I have a i5-4570, and an asus h81-plus motherboard, i'm trying to overclock the cpu from 3.2 ghz to 3.4 ghz, and if i manage to OC it, will it still last for some time or not?
thanks.

Whether it lasts or not depends on how high you overclock it, how much voltage you use, how good your case and CPU cooling is and how hard you ride the processor as far as time spend at full load. If you game on a high overclock, that does not have Intel speed step enabled so that the cores can relax when they do not need to be at full load, then it will not last as long as one that can.

Regardless, you might want to make sure you can even overclock on that board. I know it was enabled at some point by the board manufacturers but I think a CPU microcode was later released to disable overclocking on any board from that gen that was not Z87 or Z97. Much may depend on what bios version you have.

See this thread for a bit of detail.

That's a locked CPU, you can't overclock it (other than a tiny bump to BCLK that risks system instability). It'll automatically turbo up to 3.4 GHz on all cores anyway, so overclocking to 3.4 GHz wouldn't really get you anything...

Well, technically it would. Most CPUs won't allow the same maximum turbo speeds if all cores are in play that they will on a single core. So being able to have 3.4Ghz on all cores would be better than whatever the all core turbo speed is by default. This might be something that is changeable in the bios, but you also have to be aware that the voltage scheme used is not intended for an all core clock speed like that so you will likely have to make adjustments to core voltage to compensate, if the bios allows it, much the same as you would if you were overclocking manually to that speed.

However, I agree, of course, and I did overlook the fact that that is a locked SKU and cannot be overclocked except by BCLK, which is not worth doing and likely will create other issues elsewhere with your hardware if you do. I'm pretty sure BCLK is tied to other hardware in the system on that gen. I don't think they were uncoupled yet at that time.

@darkbreeze the max single core turbo for that CPU is 3.6 GHz. 3.4 GHz is the all core turbo.

Well then, you'd be correct.
