How do I overclock my i9 13900k CPU more than 5.6 Ghz when I know others have gone to 6 Ghz+?

[Yolo_gamer]

• I have an i9 13900k.
• MSI Pro Z690-a DDR4.
• Arctic Freezer II 420 A-RGB

I am trying to overclock my CPU to see how far I can go but my CPU crashes at 5.7 Ghz when I know it can get up to 6 Ghz+ because I have heard many others have done it

Temps are not a problem because my CPU sits at 85C-95C. How can some people get 6 Ghz+ and even 8Ghz+ but I can’t even get to 5.7 Ghz.

I have adjusted only the multiplier to x56 so it’s running at 5.6 Ghz but if I increase it by 0.1(5.7Ghz) and I run a stress test (FurMark) the screen goes black and the stress test stops and then Windows pops back up on the desktop like the moment just before I started the test.

Am I missing something? For example. it’s not got enough voltage.

How can I push my CPU further than 5.6 Ghz?

 

 

p.s. I’m new to LTT Fourms and may get a few things wrong e.g. question layout

Do you have all the cpu pwr plugs connected and a suitable psu?

I think you need to increase voltage if it crashes without reaching 100C

I don't think you can reach more than even 6GHz on normal cooling

[Slizzo]

Those 8GHz runs were on LN2 - Liquid Nitrogen. With lots of additional voltage.

 

If you're trying to overclock without giving the CPU additional voltage, then yes, it will crash and not work. But that cooler still may not be up to the task of cooling with the additional clock. Who knows? You'll have to experiment with upping the multiplier and the vcore and see if that works.

[WereCat]

You need to increase voltage which will massively increase power usage and temperature. So you need the custom CPU mounting bracket that makes the CPU contact against the cooler more flat for better cooling and maybe some IHS lapping and good water cooling loop.

 

FurMark is a GPU power virus it shouldn't affect your CPU. Screen flashing black means your driver probably restarted, if you had unstable CPU you will most likely get BSOD.

[Yolo_gamer]

The voltage has been increased to 1.350v from 1.236v and it still crashes. 
the cpu cooler as mentioned is the arctic freezer ii 420 a-rgb which can definitely handle the temperatures because it’s a 20C temp drop from the Corsair h150i elite capellix and it sits at 80C to 90C at5.6Ghz

also I use the cpu burner on furmark and if my gpu was crashing it shouldn’t affected by the cpu being 5.6 or 5.7Ghz

Then your chip just won't do that clock stable. Either at all, with current temps, or you're having a bunch of vDroop, something like that. Increasing voltage does not instantly equal "chip go faster".

Prime95 smallFFT torture test is what you want to blast OCs quickly and find out if they're stable or no.

Note temps are fine and voltages are so solid only the occasional 0.01 drop and at worst 0.05 drop on 12V+ aka 11.950 but I will try prime 95 for my future testing

90C is pretty hot, completely fine for stock operation but you're asking the chip to run outside of stock settings, higher heat can cause instability then.

vDroop has nothing to do with the PSU's voltage it spits out, it's the vCore "drooping" when under load. It may drop from the 1.35v you set in BIOS down to 1.2something. If that is the case, you would have to look at LLC (Load Line Calibration) and vDroop settings in your specific mobo BIOS to see what you can do about that, or just set a higher starting voltage in BIOS, so long as you're comfortable with the chip pulling that voltage when idle.

I’m using hardware monitor and across the board the biggest drop is 0.01 excluding 12v+ including IA and VID and CPU voltages. 

also in bios I have loadline calibration control the options are modes 1-8 and OV what do I pick

HWiNFO64 is more reliable and picks up more sensors. For vCore specifically I just use CPU-Z though, and keep an eye on the vCore as the chip goes under load.

I don't have your motherboard, so I don't know. Try level 3 I guess? See how voltage behaves under idle and load vs without it on.

I use Cupid HWmonitor. 
The cpu is at 80C to 90C with P cores at 5.6Ghz and E cores at 4.4Ghz.
once my pc started crashing with Pcores at 5.7Ghz i turned it down to 5.6 and incrementally brought the Ecores from 3.8Ghz to 4.4Ghz and stopped because I don’t know how bad it is to go higher with E cores but I did try 4.5Ghz and there was a single crash then I stopped. 
when I get back to my pc I will try mode 3

also the included image is what I see in the bios

[Yolo_gamer]

What does LLC do and what do the modes mean based on the image?

From what info I got mode 1 and 2 increased voltage and 3 stayed flat and 4-8 is lower but even with that I got a blue screen at 5.7ghz 

irql not less equal

but also zcpu reports core voltage 1.310 and it drops to 1.280 and once to 1.271

Furmark is a gpu test not cpu bro

Actually furmark has a cpu burner which pushes the cpu to its limit and I have used for ages to get a good test for my cpus

https://www.msi.com/Motherboard/PRO-Z690-A-DDR4

"14 Duet Rail CPU Power System
Smart Power Stage / 55A"

That board was just not built to overclock such a high power use processor, the z690 was always more geared towards the previous generation and your MSI Pro is not a top tier board either.
The cheaper z790 boards more geared towards the 13th gen Intel processors have 16+1 and 60amps, but even the more 13th gen Intel and OC focused 690 boards like the Gigabyte z690 Aorus Master had 20+1 and 105amps.

It might not be your only problem as success is down to all of the components including how lucky you are with the processor itself, but it definitely is a problem. Better power stages for stability is one of the main reasons technical people look to buy the more expensive boards.

First the Mobo - it's just not capable of handling that power, but also what PSU are you using? Even with stock boost the 13900 goes over 250W so with increased voltage, you'd have a lot more power draw as well and your PSU could not be up to the task as well.

[Yolo_gamer]

sorry for the late response..

i am using a corsair hx1000 1000w psu

i am now using a msi z790 tomahawk ddr5 mobo but still have the same problem 

i have seen it get upto 280W at 5.5ghz and with 280W/12v=~24A its still less than the 90A max(shown below)
