Help boosting I7 8700k 3.7 ghz to 4.7ghz

[Elliott]

Hello, Im new to PC so I don’t really understand what to do. I have a i7 8700k 3.7 ghz, apparently this cpu has a max frequency of 4.7 ghz. I went into my BIOS and turned on intel turbo boost and set my power to high performance and now my cpu reaches a max of 4.3 ghz. My question is how to I get my cpu to its max frequency (4.7ghz)? Do I go into my bios and just change all my core multipliers to 47? And also will this give me a little more FPS in games? And can It harm my pc??? I don’t want to overclock over its max frequency only within its limits. I also have a pretty good liquid cooler so the heat shouldn’t be a problem, if it is I’d set it back to normal. I’d appreciate easy to understand solutions please as I don’t really get the pc stuff yet

There is no max frequency really.
4.7 is just listed as such by INTEL as per the specs for when Turbo is being used, which is automatically handled by the Motherboard + CPU as it sees fit to use, which will only happen on highly demanding tasks for the most part.

Before I make suggestions, which Motherboard and RAM are you using?

If un-sure, install and run CPU-Z
Then click on Validate > tick the Extreme-OC box (this puts a load on CPU temporarily) and then click on Submit. After your web-browser loads up, copy and paste that provided web-address into a post here, as a means of sharing your PC Specs.

4.7ghz is max turbo frequency those cpu’s generally go to or over 5ghz veryeasily if you know how to overclock do it set your cores to 4.7 and adjust your voltage if it fails a test adjust it just a little higher. Since you’re using an aio it should handle 4.7ghz all cores easily assuming its 240mm or better

I’m at work at the minute, but my motherboard is a gigabyte z370 AORUS ultra gaming 2.0 motherboard and I have 16 GB DDR4 RAM (2x8gb)

To reach 4.7 GHz without overclocking you need to run application which uses only one single core. You can turn off other cores in your OS settings to achieve that.
If your turbospeed is only 4.3 GHz that means that all six cores are in use. This is quite normal.

Can’t I just set all cores at 4.7 ghz? I don’t really wanna mess around turning cores and stuff off

Set the core clock multiplier speed to the turbo clock multiplier speed and leave the turbo clock multiplier alone....boom...you have it running at 4.7GHz regardless of core usage...

Of course, you can overclock your CPU.

[Bad 💀 Motha]

Disable C1E, SpeedStep and Turbo.
Enable XMP for DRAM
Adjust multiplier until the CPU Clock = 4700 Mhz

[Elliott]

What is XMP? I know nothing about pc’s I’m new to it sorry, and could someone post a picture of there’s please? What it’s mesnt to look like running at 4.7?
So can I just go to each core instead of auto just put 4.7 next to them all, save and exit then done? I’m running at 4.7 ghz?.
Also will this harm my pc is anyway setting it to 4.7 ghz instead of staying at my turbo 4.3?

Not as easy as that with Gigabyte Motherboards.

With Gigabyte Motherboards to Overclock you have to do much more. With other motherboard too if you want to OC effecivly btu explaing that would take to logn atm for that I have already awnsered it mutliple times in thsi forum and posted how to OC way beyond basic with max efficency.

How to overclock with gigabyte Motherboards:
1st: get into BIOS
2nd: select M.I.T. -> Advanced CPU Core Settings -> Advanced Frequency Settings -> Disable "Intel Speed Shift Technology", "Enhanced Halt (C1E), "C3 State Support", "C6/C7 State Support" and "C8 State Support"
3rd: select Chipset -> disable VT-d (and Internal graphics best too)
4th: Go back to M.I.T. -> Advanced CPU Core Settings -> Advanced Frequency Settings -> and select your CPU multiplier to a rate you want to run it at.
5th: Select M.I.T. -> Advanced CPU Core Settings -> Advanced Power Settings -> CPU Vcore Loadline Clibration: 4
6th Select M.I.T -> Advanced CPU Core Settings -> Advanced Voltage Settins -> CPU Vcore: (not higher then 1.350V unelss you know what you do, you going to kill your Mosfet/VRM otherwise, that motherbaord is a poor OC board).


Asus is mroe of a mess but thsoe motherboards offer a bit more controlled OC'ing. DO one step wrong and you could create either a emss or it wont OC correctly espacially if you forget to disable VT-d.

Woow okay thank you for that info. I didn’t realise you have to do so much just to boost it from from 4.3 to 4.7. Is that little 0.4 boost even worth all the hassle?? Will it give me better FPS? And is it safe for my pc? Or shall I leave it with turbo boost on just getting max 4.3 ghz instead? I don’t wanna kill my pc I’ve only had a month haha. I’m new to pc so the second I see anything technical with pc’s I panic so going into the bios is very scary haha especially seeing all that stuff I have to change around

[vadim]

As a rule of a thumb: if you don't know how to overclock - don't do it.

[Bad 💀 Motha]

You can't hurt anything really. Your PC will be stable, or it won't be.
Just never change voltages and if you do, don't raise them.
The reason to lower CPU VCore though is because it usually can push much higher voltage than ever really needed when left on AUTO.

[Elon Mosque]

There should be enchanced multi core , or multicore enhancement in BIOS. Enable it and that should get all cores to 4.7 automatically.

I heard doing it that way makes it unstable? What voltage do you have on yours after doing it that way?
