From I just read quickly I don't think it can be done on an Asus Prime B250M-A but thought I'd ask anyway I did a cheap upgrade for my daughter with a free motherboard and a 6400T with 16gb of ram as my daughters old AMD 1045t wasn't cutting it anymore. She is really struggling to play wow on it and GTA V crashes regularly which is annoying as it takes her an age to load. She has my old Samsung 830 Evo 500gb drive and win 10. Can she overclock at all or do I need to be looking for a 6/7700 cpu which she really cant afford after being furloughed for nine weeks like so many others.
On non-K chips, you're limited to tweaking the BCLK (or whatever it's called now), assuming your board's BIOS has the option.
Yeh I have a 2600 non k and managed to overclock that to 4ghz which I was surprised at, I have the K version as well now which happily runs at 4.2ghz all day long.
The 2600 had an unlocked turbo multiplier of up to 4x. So that is why you overclocked that. With this? you have no option. Touching the BCLK is a total waste of time, as you will be lucky to get it to 103 without losing your drives and possibly your data.
You can only overclock on a z170 with an early bios. With this you can overclock by the base clock. got the nephews i5 6500 up to 4.5ghz doing this
