New CPU or New motherboard: Overclock a Non-K CPU

Recommended Posts

Posted · Original PosterOP

Hello everyone,

 

I have a B150i pro game AC mobo and a Core i5 6600 CPU. I wanted to overclock the CPU but my mobo doesn't allow it on non-k CPU. I found out that mobos whith z170 and older bios could do the trick. Should i buy another motherboard (wich will be cheaper buy might not work) or should i buy another CPU (second hand or new, but it will still be more expensive) ?

 

Best regards

You can't overclock non K CPUs anyway. So you would need a new CPU too if you get Z series board.

It seems like its indeed possible, but only on z170 chipset mobos

There actually are ways to overclock non K CPUs, but it's kinda difficult and probably not what you're looking for, so you're best off getting a Z-Series motherboard and a K CPU


75% of what I say is sarcastic

 

So is the rest probably

If You can get a decent z170 mobo for cheap. I'd say go for it.

You can download 1301 bios and install it. You dont have to find a z170 with an old bios.

I'm running 

I5 6500 @4.3ghz all cores sync

My is xmp @ 2400mhz, but running at 2660 or 2700mhz. Becuase of how blk OC effects more then just cpu oc'ing my

 

your biggest challenge is watching temps. Occt works well on win 10. But hwmonitor with sensors only is better on win 7

You need to flash the Z170 motherboards in order to overclock non-k CPUs, don't you? So you have to take the risk first, second, the non-k CPUs are maybe the worst CPUs to overclock, don't think you can reach a clock speed as high as an OC K chip

Either you have a very nice CPU capable of OC high, or a shitty CPU that won't OC over 200 MHz, that's the second risk

No more of a risk then updating a bios.

1301 comes from der8auer. So it's pretty safe.

 

Base clock on my i5-6500 is 3.2ghz. Only 1 core boost to 3.6ghz the other 3 cores will only boost to 3.3ghz.

 

With my 1301 bios my oc is

4.3ghz all core sync.

Which is a great improvement.

 

And if the OC potential was so crappy Intel wouldn't need to lock down the cpus from oc'ing. Dont get me wrong silicon lottery is still a lottery, but I think it's worth it. If you can get a board at a decent price.

Thanks, for the information.

Considering that Z170 motherboards are about as expensive as Z370 boards still I'd just ditch everything and get Coffee Lake, those extra cores will do far more difference than BCLK overclock of a locked 4c/4t i5.

IMO not worth the pain. There are some limitations to non-K OC, and there are degrees of broken-ness if you do it. Two known factors are AVX performance is crippled you might as well buy a Ryzen at that point. The other is per-core temperature monitoring doesn't work, but package temp still does. The potentially worst one is that you need an old microcode. This probably means no Spectre/Meltdown patches, and if Windows soft-loads microcode it can break the OC too.

 

If you have the stuff already and wanted to have a go to say you done it, maybe. If you have to buy stuff, look to upgrade instead.
