I5 6400 Overclock?

[Dubesta11]

Reading up a little, most motherboards now allow the i5-6400 to be overclocked, to as much as 4.8GHz. With proper cooling and a Asus Z170-E, would I be able to at least push any chip to about 4GHz? I don't quite have the budget to buy a 6600k, especially if I get get similar overclocks and save over $70 dollars.

 

Edit: Probably paired with a 1070, or 1060 if prices go down.

Why sell your i5 4670k? It is still is a very nice cpu and overclocked better than an i5 6400

Intel took measurements and "banned" this feature for motherboard manufacturers with a microcode update.

However Asrock found a workaround, but it's only on some specific motherboards.

I am getting more then I paid for it (180 vs 160), selling my whole system to upgrade to 1151 components, and don't need breakneck performance. So I'm getting nicer, newer components for the last 3 years of college that will all be under warranty.

I don't see any bottleneck with the cpu you have. If you wanna get better peformance in games, you should upgrade your gpu.

No, Intel didn't push any microcode update. You can always flash back to older bios.

It's not about a bottleneck, I'm selling my entire system for a lot of money, enough to upgrade to new parts for free. I might just go with the 6600k / 1060 combo for stable overclocks.

kepp component like cpu cooler, psu.

Not true. You can still do it just fine, so long as you use the older code (which can be achieved with older Bioses or with a few mobos that allow you to manually select the microcode to be used).

See above.

You can do it, but:

1. You need a Z170 mobo.
2. You lose AVX support
3. You lose your iGPU
4. You lose core temp readings
5. Cache runs slower
6. You lose all power saving features
7. You must use an older bios, which means missing on fixes and features (unless yours has an option to select the microcode to be used, but very few actually support it)
8. Windows can push an update at any time and screw your OC over. Nothing irreversible, and it's very unlikely to happen. But a pain noneless.

In sum, it's not recommended. You sure you still want it?

No, I decided to just spend the extra money on a 6600k and probably a dual-rad AiO

They actually did...

Some boards will still let you OC if you can find the OC bios for them, which was took down/modified from the official download sites (except for asrock, which now has their own locked OC boards)
