i5 6500 Overclock

[boba99999]

I was browsing the BIOS of my computer and in the 'overclock' section I saw that I can increase the base clock of the CPU (i5 6500). Is this considered overclocking and how much performance gain can I get?

It is considered overclocking, and while skylake considerably improved base clock overclocking, don't expect any crazy speed increases.  Try taking it up from 100 to 105 to start and see how that goes.

It would be an overclock, yes.... however, unless you have a Z170 board with a proper Bios version, the computer just won't boot if you mess with that. And even if you have the right conditions, there are a plethora of problems associated with such OC, making it highly unadvisable.

.. which problems?

 

IGP won't work anymore - isn't a Problem if you have a GPU

... soo what else? You just shouldn't forget to change RAM speed..^^ - everything is fine.

 

I wouldn't call this aspects "problems" ...

1. You also lose AVX support.
2. And your thermal sensor.
3. And all power saving features.
4. Cache runs slower as well.
5. You miss out on Bios updates with fixes and stability improvements (unless your mobo allows microcode selection).
6. And you risk windows making an update and unexpectedly locking you out of your OC.

Pretty much these. And the iGPU, which you've mentioned yourself.

Wow.. didnt knew some of your points..

 

.. is AVX really that important? What does it make for a difference?

How much slower will the Cache get?

 

What do you think about this?

 

He could read out his Temperature..

If your programs take advantage of it, yes, though very few actually do.

Not sure exactly... I think it was slowed down to 3/4 the normal speed.

That's package reading. While that still works, it isn't as precise as per core reading; a single core could peak higher than the package reading, for example.
