Should I disable integradted GPU with new dedicated GPU?

[AntDeek]

Installed a new GT 710 into my PC today, and was wondering if I should keep the Intel HD 2500 enabled in bios or disable it altogether.

 

[Jetster]

Doesn't matter. It will show up on heaven bench mark that's about the only down side. And that's not even an issue really. Doesn't affect anything

 

[Bill_Bright]

When you install a graphics card, most (if not all) motherboards will automatically disable the integrated graphics anyway to free up any "shared" RAM, conserve power and system resources.

 

[AntDeek]

Yes, but Device Manager still shows "Intel HD Graphics" even though display output is set to GT 710.

 

[Kursah]

That's because it isn't disabled, so Device Manager should see it. That is not a problem nor should it be a concern. Frankly I like to have them Auto or Enabled. For those times if you need an extra screen output and are out of them on your graphics card (not for gaming obviously) or when your graphics card dies pull it, migrate the cable(s) over to onboard and be done with it.

It is entirely normal for the iGPU to still be detected, I wouldn't waste much time worrying about it in all honesty.

 

[Bill_Bright]

I agree it is not a problem, but for me, I don't want extra devices enabled when not needed. It is odd yours still is with an installed card.

You did not state what computer or motherboard you have, nor are your System Specs filled out so we don't know. But I do find it odd yours is not disabled as I noted before, normally they are automatically when a card is detected by the BIOS.

You should easily be able to look in your BIOS Setup Menu and see what it says, and disable it there, if you want. You should also be able to look in Task Manager to see if it is taking up any resources.

If your dGPU dies you'll want that iGPU enabled.

 

[erocker]

I would. No need to have it on, it just adds a bit of heat and power, plus there are always those times when it doesn't mesh with an app/program well.

 

[Bill_Bright]

If your dGPU dies you'll want that iGPU enabled.

True. But if your graphics card dies, you won't be able to see anything anyway until you swap cables over. So it is easy to shutdown, swap cables, pull the card and the integrated should then re-enable itself, or you can boot into the BIOS and enable it.

I agree with erocker, no need to add more heat and consume unnecessary power just for the remote possibility of some rare event.

iGPU is best to have it on by default in case pci-e GPU decides to quit.

I just cannot agree. I think in the last 10 years and 6 computers in this place, I had one graphics card fail. And even then, it worked just fine in Safe Mode.

The only time I keep the integrated graphics enabled with a card installed is when I have a 3rd monitor attached and the card only supports 2.

 

[alucasa]

The iGPU is disabled (thus does not take any RAM) when pci-e based GPU is active. It shows up in device window and that is it. It starts to take RAM only when a cable is connected to onboard video output.

So, it doesn't matter either way, so having it active doesn't do any harm.

Either way, each to their own. I prefer to keep it alive. You do not. That's the end of our story, I guess.

hello i bought a 1070 asus z170-a 8 gb ram i5 66k 750 psu brand new cant get picture on monitor red light next too ram and green light at bottom all the bells and whistles are running and icrii cant use my system...

He's already got a thread about his issues and it has replies.

Well there are those iGPU things like Quicksync and I thought there were some other features you could use in conjunction with a dGPU. I've never used the iGPU my previous P67 had no vid capabilities so my 2600Ks iGPU never even saw power. I of course just disabled on my current rig just out of habit.

Bottom line leaving it on won't "hurt" anything other than eating some RAM but nothing stopping you from disabling it in the BIOS if it bothers you.

 

[Jetster]

So it doesn't matter still stands. Lets not forget AMD dual graphics uses them both and Intel well use to have Lucid Virtu to boosts your Dedicated GPU. Was seen as cheating on benchmarks so both you would leave enabled

If you leave it enabled you need to install the motherboard graphics drivers. But 10 probably does that by itself

Best idea right there even more so if using windows 10.

Yeah that's what I want thinking of, Lucid!

 

[EarthDog]

Actually, it can still be enabled in the device manager but not using system ram and in its low power states. I don't even install a driver (though Im sure W10 has one at the ready). I dont care either way, left it as whatever it was on by default, except when I was benching under LN2 and 'really wanted to make sure'. I wouldn't take the 10s it takes to flip it off in the BIOS or disable in on the Windows side. Zero reason to.

 

[Bill_Bright]

It matters to some. I see no reason, advantage, or benefit to keeping it enabled with a card installed.

And again, in most cases, it is automatically disabled when you install a card.

So, in reality, leaving the iGPU disabled in the bios (windows can NOT see it) isn't going to harm any performance, just make the CPU run cooler? The iGPU is a Intel HD 2500 and the Dedicated GPU is the GeForce 710 2GB.

Yes that is the long and the short of it. If you're not using it there is nothing wrong with disabling it in the BIOS. That said the 710 is no powerhouse either so maybe Jetsters suggestion on Lucid Virtu might actually benefit you and give you a boost. But that is for you to decide and well if you can use the tech of course

 

[EarthDog]

Id like to see some actual testing on that... as I said, if you have a discrete GPU, the iGPU will not be used. It will not allocate ram. It just chills.......at least on the ASUS mobo I just checked (MVIIIE). It has voltage readout for the iGPU... when running with a discrete GPU, it has none. In device manager under display adapters, I do not see an iGPU entry to disable. It is on AUTO in the BIOS.

Seems like it does it for you...so no other effort is needed. Save 30s of you life by not disabling in the BIOS and leave it alone. Or if you want to disable for giggles, that is OK too.

NO!!!! That is not true at all! It may not affect performance but it sure is not going to make the CPU run cooler.
