BIOS Setting That’s Ruining Your PC - Turn it Off Now
So this video initially started off as me testing if using your iGPU to run your second display could improve performance, as yes running multiple displays can technically harm your fps, but to be honest, the results weren’t really that interesting.

Sure there were a few examples that showed a measurable increase in by using the iGPU, but when we look at the average across 4 games, the difference is absolutely tiny, surely nothing worth making a whole video on, and I was about to throw in the towel, but then I started digging around in the BIOS, and what I found will definitely surprise you, and no it’s not XMP or any type of overclocking

In fact I want you to put what setting you think I changed in comments right now, to see if you get it right, because I bet most of you won’t

Ok, ready, well on my 7800X3D system I actually disabled something many people tell you not to as it apparently can reduce maximum clock speeds, but I found this to not be the case on my Asrock board, and that setting is C-states.

Now C-states are a setting which essentially controls the sleeping or down clicking states of the CPU, so by disabling it we are essentially forcing the CPU to be ready at any moment. This in combination with using the ultimate power plan and setting the windows minimum processor frequency to 100% insures all cores will run at the maximum speed allowed at all times, but does it actually help, let's find out.

Now real quick the system I’m using to test this actually has a 7950X3D simulating a 7800X3D by disabling the non cache cores, a PNY XLR8 RTX 4090, 96GB of DDR5 running 6000 CL30, an 800GB Optane P5800X boot drive, and 4TB Kingston Renegade Fury Renegade Gen 4 SSD which was sent to me by kingston all running on a SFF Corsair 1000W PSU

What settings do you use for the best performance? Let me know in the comments below!

Why does this guy's voice sound like his trying to sell you something all the time 😂😂😂.

[JustMyFish]

C states turns off idle cores. The stuttering you get is the cores being reenable when needed. That’s why turning it off illuminates stuttering. When off It leaves the core in idle mode at normally 0.1 MHz when is turned off it is 0 MHz, so it stutters when coming back to life. It’s not dangerous, switching off. You may see Electric bill off around $2 to $3 per year increase.

[melany]

yeah, this is a nice advice, but you have to keep in mind that without c-states the power draw, specially at idle, will increase quite a lot. on my rig which has a 5600X, enabling c-states results in a drop of 30W at idle, and since i'm living in brazil this is not worth disabling. If power is cheap on your country, I totally advice disabling it if you're having some strutters

[Crossfire]

I would've liked to see where in the BIOS menu is that particular setting.
(Even if we all have different motherboards).

[kamikaze]

If you have Ryzen 7000 and X670/E and you are suffering from random low-load or idle freezing and restarts that won't seem to go away, I found that turning Global C-State Control also fixes this issue.

[vstxp]

Well... I have a 7800X3D. Instead of consuming more power at idle, you could try opening the task manager, and setting the game process to run at high priority. That's it. Undervolting the CPU + a good AIO, and this beast of a CPU is unleashed. These two things will make the biggest difference in any game. Disabling C-states for me did absolutely NOTHING, and it increased my power consumption at idle. Not cool...

What would be interesting to know is wheter or not using the iGPU for extra monitors, when the GPU output ports are full, actually does anything to performance. Say there are 4 monitors plugged in the GPU, and you add additional monitors in the iGPU outputs on the MoBo.

[johnruscigno]

I have turboboost that works with the cpu and gpu. C-states on it idles low but can go well above it's base frequency. C-states on, it just stays at its base frequency all the time but won't go above it either. You can check it out by clicking on task manager and then performance to see how your bios tweak worked out.

[KeVsPIXEL]

Do not do this if you care on how much your power bill is going to cost, not worth it.

[pakjai]

Nowadays, we value power efficiency a great deal. Not just about raw power like back in the days. Energy costs are too darn high these days that people are willing to underclock and even take a few percent off to cut down their energy bills.

[hegolikit]

WOW 1-3 FPS difference bro thats insane

[FFox]

The whole "OMG Disabling the C-States increases my power consuption x1000%" Not the case. Even if the clock speeds are always at max speed there is a difference between the CPU being UNDER LOAD vs IDLE. Disabling the C-States fixed a lot of my gaming problems where the clockspeeds were jumping up and down causting stability problems. For overclockers this is also the right step to make it'll make the whole CPU more stable. So yes, max frequency isnt the same in load vs not. Depends on how much the application requests the CPU too. Power draw isnt always the same.

Title has BIOS but video none of BIOS were shown and yet 43K views

[theshuff]

pro tip : keep your c state enabled ! nothing to worry about you 0.1% frame rate and keep your energy consumption as low as possible :D

[Kapono]

I just don’t feel comfortable doing that to my 7800X3D. I’m extremely happy with it and I don’t have any stutters like Conner system has

[SonixAEP]

This is a really helpful video especially knowing that 'The Finals' is more leaned towards being cpu intensive game

[tarkitarker]

ahh yes, the glorious trick of disabling every powersaving feature for 1% performance gain. truely ingenius.

[cosmicusstardust]

I remember hearing about disabling C-States back when the Ryzen 7 2700X was still a thing, it did have some noticeable improvements in performance when I tested it with my 2700X, though intel doesn't seem to matter much with that now I am on an i9-13900K

[Omega_Mark]

The system running at full speed non-stop = hotter system and louder fans + more dust inside + decreased longevity of the whole system, including the GPU. No thanks.

[casualgamer]

I turn c states off on my 5950x because it causing my system to lock up when it idols for long periods of time.
