Should I disable the GPU on my 9800X3D if I have a dedicated GPU?
Posted by skytbest@reddit | buildapc | View on Reddit | 58 comments
Upgraded to a Ryzen 9800X3D and noticed that my system is recognizing it as a GPU. It's my first time using a CPU with integrated graphics so not sure if this is a problem.
All my monitors are plugged in to my dedicated GPU but I'm wondering if it would be beneficial/recommended to disable the GPU on my Ryzen chip?

Got this processor yesterday.
From what I've seen on HW monitor, it's drawing some power, and adding heat while playing competitive games on 1080p, so I've disabled it.
Don't forget to set the negative curve of -30 in BIOS, if you have temperature problems. Cheers!

Wdym by setting the negative curve? I've been having issues with my 9800x3d recently while playing marvel rivals, if I don't cap the frames to 60 fps my CPU is hitting temps of over 95 and then shutting off in the middle of a match. Trying to find solutions. I have a 9800X3D and a RX 7900XT so I feel like it should handle 120 fps on rivals easy
Tails_Swifty@reddit
you need to fix your cooling for your 9800x3d...
avalyntwo@reddit
5 months late here, but not everyone's chip can do -30. Mine does -27 all cores (though I'm sure some could do -30 if I did core by core). Higher than that and I saw performance degredation.
kevin6040@reddit
I could only do -10 on my 9800x3d
LLMprophet@reddit
Just adding another data point:
I'm at -14 on my 9800x3d.
Anything lower crashes AIDA64.
avalyntwo@reddit
Yeah not everyone are as lucky with their chips unfortunately. But it should perform well anyway 😉
It might be you can set a bigger number for some cores while leaving the worst cores at -10 though. But you’d have to find a guide on how to spot them if you don’t know which ones are the high peforming cores.
No-Pollution-4874@reddit
I think all 9800x3d can go -30 depending on what mother board is used.... reason being is some mother board apply more voltage from the jump. I had a gigabyte x870e pro mother board i was only able to hit -25 stable. I eneded buying an ASUS ROG CROSSHAIR X870E for my new bulid and was able to do -30 easily on the dsame cpu but i noticed this board applied more power to the cpu core voltage compared to the GIGABYTE. SO i would not go by what negative offset people have on here. Im at -32 on my new board no and hit the same 118 -121 watts on cinebench all core stress test as i did with the gigabyte.
avalyntwo@reddit
Yeah, board probably matters. I'm on a midrange B650 board myself. But it works well for what I need it to do, so I'm happy.
Goloith@reddit
FYI, PBO Tuner allows you to go to -50.
nazrinz3@reddit
What's the setting called to disable igpu? Can't find it on my asus mobo
Ironkidz23@reddit
It's under the "onboard devices configuration" in your bios settings.
Plantony@reddit
whats that negative curve thing? i got mind today and while i wouldnt say i have bad temps, i'd rather have them a little lower
Mountain_Might9495@reddit
i also got mine 2 days ago and i did the curve optimiser basically you can look up a video on youtube on how to do it on your motherboard
it worked for me when i was playing need for speed heat which notoriously handles cpus bad so its worth even a -10 apparently people can get -40
aguswings@reddit
there is no certainty on the benefit? How come the community is so divided in this topic?
Ancient_Duty6192@reddit
disable it, it will reudce the chance of stutters, something it fixed for me.
Remote-Lead-3794@reddit
I would just add that I disabled my 9800x3d igp because it was hoarding 2 gigs of my main system memory allocating them specifically to the igpu. I have 64 gigs but I wasn't about to knowingly give up two gigs of it for no reason whatsoever. It certainly doesn't hurt to turn it off and you gain two gigs back and debatably there's some power draw so there's also going to be some heat generated. Even if it is all small amounts....
StatusRice2@reddit
I paid a professional to optimize my pc for bloat ware from fiver with more than 1500 optimizations. He disabled my igpu on mu 9800x3d he said it tanks performance big time and you don’t really ever need it. Now I know why, thanks
No_Homework_8890@reddit
hey can u share details about debloated system? like the price where did u buy and stuff and if its worth it
Ok_Combination1951@reddit
dont pay noone over 50 bucks for that shit just do a clean win install and delete all programs all u need to do and go in bios and disable gpu its easy
StatusRice2@reddit
Its from fiver the link is in the reply above^ it also depends on what you want done, if its just bloatware removal then its somewhere around $50-70? Other stuff are more. If you are struggling on games its worth, especially if its cpu problems. It makes your overall pc/games/ping much better. Worth it imo. If ur rig is really good then not necessary at all
MrG-onpc@reddit
Who did the opti I need my setup doing
skytbest@reddit (OP)
How did you determine that it was using 2 gigs of system memory?
Remote-Lead-3794@reddit
I believe I first noticed it in the performance monitor tool in Windows. Total available ram was missing a couple gigs. I didn't even realize that there was an igp until that moment but I figured there was based on missing a couple gigs. I found that there was an igp present so I went to my bios and turned it off. Booted back into windows and I had my full 64 gigs of RAM available.
skytbest@reddit (OP)
Oh wow, you're right. I just disabled and it and got 2gbs back. Compared the total "committed" RAM in the task manager's performance tab from before and after. Thanks!
Remote-Lead-3794@reddit
Glad my OCD helped someone out! LOL
Elden-Mochi@reddit
Me too. I have 64GB and was wondering why it only showed 62GB. I also upgraded to that cpu.
I'll never need that 2GB but it still bugged the heck out of me.
ubermk3@reddit
I disabled my 9800X3D igpu in bios and now have no video signal even though my dedicated card is clearly on. Did you have any issues like this?
Elden-Mochi@reddit
I never actually turned mine off because I'm not using most of my ram right now, but i was curious why it all wasn't there .
There should be a section in the bios to choose what gpu has priority, and you could select the dedicated gpu.
-seoul-@reddit
It maybe is new but in asus/ami bios, this exact setting exists and many more alike
ubermk3@reddit
Yeah I selected the external gfx priority setting in bios but selecting dGPU only mode still leaves me with no video signal.
I think the iGPU is interfering with some Steam games launching properly which is why I want to disable it. The games basically freeze instantly upon launching before even getting through the splash screen. I have the 7900XT selected as primary in windows settings for the games/apps I want it used for but no luck.
RynoSauce@reddit
Buying this chip tomorrow, got it at $479 MSRP. This is gonna be one of the first things i'm doing to save ram! Thanks!
iamfreddyp@reddit
How do you disable it?
skytbest@reddit (OP)
It's in the BIOS settings. I would just google "disable igpu on [manufacturer name] motherboard bios"
iamfreddyp@reddit
Got it! I was able to find it and disable it. Regained my full 64gb. Thanks again!
Budget-Bee-3619@reddit
I hot 64gb ram but anyways i disabled it and also got better performance when that is sayd it means that i got rid of some stuttering in cs2. Havent tested fps or any benchmarks but i think im good on 400fps capped. 800-900 seems overkill
Xendrus@reddit
Do you remember how you disabled it to reclaim the 2gigs of ram? I am missing 2gigs also and disabling/uninstalling the igpu in device manager didn't return it.
spectreVII@reddit
So I’m kinda new to modern pc’s with integrated graphics, I just got a 9700x and noticed it on the display adapters in a game, but when I took the hdmi cable from my graphics card and plugged it in my mother board hdmi port then switched to the integrated graphics adapter from within the game instead of my 2070 super, nothing changed. The game still ran at the same frame rate. Not sure if I had to do a full system reboot or not for it to take effect but since nothing changed in the game, I figured the igpu was useless so long as I had my 2070 super installed.
Is there a as proper way of making a game use the igpu rather than the dedicated one? I just like to tinker to see what things are capable of, obviously I wouldn’t keep it that way.
PestilenceReigns@reddit
How would that be possible if you changed the HDMI source to the motherboard physically?
Btw: I'm curious as well as to when to use the iGPU when doing lighter tasks/running lighter applications to be more power-efficient..
mtuan293@reddit
If you plug your monitor into the motherboard, your 2070 super renders the game then passes it through the igpu, pretty like the old Optimus switchable graphics tech on laptops.
You can go to Settings app > System > Display > Graphics and play around with the settings there.
0-_-000-_-0@reddit
I disabled it. No real harm to doing so, plus with it just idling it's likely using small amounts of power and creating heat, and as others have mentioned it takes up some system memory too. It probably won't make a real world difference but it might run 1% better which is worth it if you have a nice chip like that.
Other optimizations I did are -10 on PBO, and enabled amd smart access memory with my GPU.
psimwork@reddit
You CAN, but there's no benefit by doing so. I personally just leave it alone.
monsieurpooh@reddit
What about power usage? MSI afterburner claims it's using 17-35 watts doing almost nothing; shouldn't everything just be handled by the dedicated GPU?
skytbest@reddit (OP)
Turns out it saved me 2 gigs of RAM. https://www.reddit.com/r/buildapc/comments/1gud3ys/should_i_disable_the_gpu_on_my_9800x3d_if_i_have/maunpav/
Ithian021@reddit
Thanks for posting this. I got the same 2GB back!

Disable amd igpu asus hero motherboard
dkizzy@reddit
I will add that updating the video driver after big Windows cumulative updates can be helpful when you have a wonky desktop issue appear. You can download the adrenalin driver and just select driver only, that way I'm only using the nvidia app vs two apps loading.
-MeTeC-@reddit
What do you mean by wonky desktop issues?
Halbzu@reddit
it makes no difference whether you disable it. there is no igpu to video card passthrough
intelceloxyinsideamd@reddit
yes there is on my 7900xtx
Yes_butt_no_@reddit
Apart from this one, of course
Anakiev@reddit
For some reason google couldn't serve me the proper information, but you did. Thank you
Halbzu@reddit
t think you're talking about a different topic. what you linked to are benchmarks of using only the iGPU.
but OP asked whether disabling the iGPU will make any difference to CPU or dedicated GPU performance.
Yes_butt_no_@reddit
I misread your response to be fair, and thought you were claiming there is no iGPU.
But as it is using a reported 30W, it seems that disabling it will make a difference to something
Halbzu@reddit
it would be very weird for it to run at 30w while not even being plugged in.
Yes_butt_no_@reddit
I thought so too, which is exactly why I googled disabling it after I noticed it in the AMD performance overlay!
Background-Floor-635@reddit
Pretty sure there are settings in the amd adrenaline software that will use it for video playback and like those ai features. So really it's not necessary unless you have a transcoding feature you'd like to use on the amd apps
Hiadro@reddit
Like the other say, it (usually) doesn't matter.
However, some programs/games sometimes have a weird issue with iGPUs being active even when not being actively used, which is hard to explain (Horizon 4 for instance won't launch for some - me included - when the iGPU is active).
So generally speaking, no, it doesn't matter if you leave it on. Disable it if you come across issues.
