Overclock i5 8400?

[Adrii]

I cant seem to find a way to overclock my pc in BIOS (motherboard is  asus TUF gaming z370) is there a way to overclock it? It would love to get at 3.8 if thats possible or even 4 ghz. Yesterday i overclocked my gpu and it runs perfect.

you cant overclock an NON K sku CPU.

Ive google a bit and it says it is able to hit a max of 4ghz?

you kinda can overclock non k cpus, i managed to get my old i5 3570 up to 4.5ghz on all 4 with a z77 board, theres also bclk overclock and possibly some other tricks that i havnt thought of

Put BCLK at 102.9MHZ, that's the max BCLK clock before the lock comes in.

That's Turbo Boosting, where the CPU speeds up to keep up with a workload. IIRC, there are ways to have it always Turbo Boost, but I forget how that works.

I know i sound like a noob (i am) the auto config for blck is 102.5000, if i type  in 102.9x will the ghz go up? And if so how much?

thats turbo boost, 2.8Ghz base 3.8Ghz boost on all cores 4Ghz on 1 core (i think)

So how do i make it 3.8? Do i need to change the numbers on the 6 cores?

If its all-core boost, it goes to 3.8ghz under load automatically and stays there as long as its not getting hot.

I'm sorry no one saved you and told you to get an R5 1600 instead....RIP

 

There's probably nothing you can do to overclock, the most you might be able to do is enable Multi-Core Enhancement, maybe.

2.8GHz only when using AVX or turbo disabled. 4GHz turbo for single core. 3.8GHz for all cores when AVX isnt used (only a few synthetics use it).

then you'll get 3.9GHz all cores and 4.1GHz single core (bclk times multiplier, which is 38 max on all cores, 40 max on single core). As long as the system doesnt crash, you can increase the bclk as much as you like.

I think it's just overclocking it to the Turbo Speed and doing some turbo boost setting stuff in BIOS.

I put it to 102.9 and 5 cores where 38 and one is 40. In speccy it still says it @ 2.8GHz ? Am i doing something wrong?

speecy, task manager and some others only show base clocks. Use CPU-Z instead.

What are the CPU-Z Results?

It still says 2.8

you have to give some load to it. Try cinebench R15

It says its 2.81 in cinebench, nothing changes, not even the speed in cpuz can get over 2600 mhz

2.81 while Cinebench test is running? Then you either turned off turbo boost or set Windows power plan inside Control Panel to powersave. Use balanced or high performance instead

That makes absolutely no sense.

You should turn on High Performance mode and make sure Turbo Boost is enabled.
