hyper 212 evo/overclocking

[Lucas6ix]

This might be a stupid question but I am new to overclocking and was just curious i have a ASUS Z270F board
Intel i56400 and a hyper 212 evo when overclocking should i have the cpu cooler at turbo? full speed? when playing games or does it not really matter at all?!

It matters, you would want to stress it first to monitor your temps before you jump right into stuff. Take it slow and see what you can achieve

You have a non-k CPU and a overclocking board, unless you're doing BCLK OCing which I don't recommend or using a BIOS workaround, most of which were patched, it isn't going to work.
In addition it's one of the lowest clocked i5 models next to the mobile variants, meaning it will be lower binned and have less OC potential.
Not recommended, return the mobo if it's not too late.

Why would I return a perfectly good board? lol and ive heard multiple people overclock these chips,just search online tons of people talk about being able to do it.

Yeah, that was months ago, before Intel released the microcode update and most of the BIOS updates were invalidated, even now very few solutions do exist, and those that do are AsRock's 100 series K4 Hyper boards, and a few BIOS workarounds for Z170.
With your board I'm sure it's not possible with that chip unless you go BCLK or void your warranty.

Thank you for that info like i said I am new..but when I boot up it says overclocked 25%

???
Did you do this using in built motherboard tuning software?
Is the actual clock speed increased?
Check it in CPU-Z, if its the same as stock, it might be over-volting the chip without an OC applied.
Careful.

The i5-6400 is base clock of 2.7GHz. It'll turbo on 1 core upto 3.3GHz, 2 cores usually a little less, and all 4 cores will top out at @ 3.0GHz. Turbo is a factory OC. That board also comes with a software capable of some small OC. What happens is either by motherboard button or windows motherboard software (Asus Suite) you can apply a BCLK OC, raising the BCLK (buss clock) from 100.0 to 103.2? or 105.7? and that affects the multiplier backwards. Being a locked cpu the multiplier is locked at 27 (27x100.0MHz giving 2.7GHz) but by raising the BCLK to 103.2 you actually OC the cpu without changing the multiplier, so 27x103.2 would give a cpu speed of 2.787GHz, or 27x105.3 would be an OC of 2.843GHz vrs the stock 2.698GHz. Under turbo speeds you could see the cpu at 3.48GHz. What they don't tell you about that is that bumping the BCLK can and does often lead to instability as it's a generic software algorithm, it's the same software used on all the motherboards, and generates considerably more heat, so should not be used with stock coolers and doesn't work very well on most low end boards. It's more of a gimmick than anything else. Does almost nothing for performance gains, has a large potential to actually hurt performance via overheating or instability.

In a word, and this goes for any software OC, on any mobo, by any manufacturer, it's Garbage.

Would you reccomend me to do the blck with the system i have? and should i have xmp off or on.

Xmp is extreme memory profile. Basically if you have ddr4, the default speed will be 2133MHz with its default voltage and default timings. By employing xmp, all you are doing is enabling a preset to something beyond default. So if you bought 2400 MHz ram, it'll run out of the box at 2133, but with xmp you change that to a factory tested preset of 2400, with 2400 voltage and 2400 timings.

Really got nothing to do with OC as you are within tested limits of the ram.

Keep the BCLK at 100.0. There's relatively little gains, your games might see 1-2 fps increase, but the chances of instability or overheat go way up. Honestly not worth it.
