Looking around the net, couldn't find much on this.

I also addressed this matter on Lenovo forums, did not receive much help. Here is the thread if anybody's interested. https://forums.lenovo.com/t5/Lenovo...-modify-integrated-graphics-vram/td-p/3298784

I have 2 laptops. Their low end,so no...i'm not rich :rolleyes:
One is a Lenovo OEM B590 with i3 cpu integrated graphics and 4gb of ram.
Noticed the integrated intel graphs run at a 64mb memory by default. You can find many tutorials out there on how to change that. Just take from ram and add to vram. I wanted to boost to 1gb the vram. you're supposed to go into bios and look there for some kind of setting. Did not find any . Strange. I tooked the battery out and reset the bios to default. Still no option. it looks the same.

However, i looked into my other laptop. An Acer...don't know the model. I remember when i got it 2 years ago, at the store the guy showed me the dedicated graphics card a 810 GT M . it was mentioned in the bios. Went home installed windows, never bothered to look in to the bios ever since.
yesterday i did. And i could not find anything mentioned about a Dedicated Card in there. TRUST me,it's just not there.

So my question is this: Can a Windows Install modify the BIOS ? Can the bios look different after you installed windows and some drivers ?

As far as i know,i think it's impossible. But look, My bios on the Acer looks different than the day i purchased it!

Only when you have updated the BIOS itself.

I did install some drivers from Acer website, cuz i figured i wanted the latest ones,not the one from the DVD.... But it was like Sound drivers, and network and...something from Integrated Webcam.


I was just putting 1+ 2 in my mind. Figured if the BIOS in my Acer changed, by magic. maybe same happened tot he Lenovo. Since i got no option to boost the integrated graphics.

This guy from Lenovo tells me ,the oem computer just comes like this by default and you can't change anything.

Might be the laptop has a built-in software from the brand to auto-check and update drivers and the BIOS.
I have a brother that has something like that on his laptop.
Or you did download a BIOS update by mistake.

What s wrong ? No place to worry ! This RAM is little , it is a kind of special RAM , the needed RAM is dynamically allocated . I have i3 too and no BIOS setting for the amount of VRAM but everything works flawlessly . Some games read at first that little amount of VRAM and show some warning but these games are badly coded for such laptops . Most of the games work flawlessly with Intel HD Graphics .

Usually the max dynamically allocated VRAM is around 1.6GBytes

What is the exact problem ?

If you have installed some driver pack from acer it may contain a new bios. It updates very silently on certain laptops.

No, BIOS cannot be updated on its own, but there are few things that might explain something:
1) For iGPU you can select a minimum amount of RAM dedicated to graphics. On certain laptops it is locked. The actual amount of VRAM is allocated dynamically, so you have nothing to worry about.
2) Regarding your Acer laptop: did you buy it from a retail store? I've seen on many occasions where even employees of legitimate stores were using bait and switch tactics to make some cash on the side. When it comes to laptops, certain models have many variations (Like Lenovo G580 that comes in 5 different flavors from Celeron 1000M with Intel HD only to Core i5 and dedicated GT 630M). Dude might have shown you an upper model with dedicated graphics, but gave you a lower one and put the cash difference in his pocket.

Just a couple of weeks ago I've witnessed an old con, very similar to the one I described, in the local electronics supermarket. A young guy looks at PC monitors and inquires about the price, an employee points to the price tag, but says that if a customer applies for a member rewards card, he can help out to make it even cheaper by using his employee discount, which would save another 10% (equivalent of $30). Following by a bunch of mumbo-jumbo he talks him into paying around $15 "helpers fee" and the guy signs up for a reward card, while silently talking to a cashier girl, which makes it look like he's actually negotiating something. After the customer left, he simply puts the "on-sale 10% off" tag back and goes back to his duties.

Heck, I almost spent an extra $10 myself, while buying PC speakers for my cousin (right speakers, wrong price tag). Good thing I checked the price against their web-store on my phone, before going to the cash register.

Or the salesman did the old switch on you, showed you one product and then gives you one worth less.

Yeah, this is going nowhere.

My best guess is what @R-T-B said. Still a silent bios update from a Acer software that i might have installed does not justify the bios not showing up the graphics card anymore. Looking around on the net, more people show that a driver in the windows can cause the bios to change....even tho nobody has an explanation.
As for my Lenovo,it's an oem computer and the vram is allocated dynamically witch is horrible,best way to do it is to manually allocate ,but i never figured i need this feature when i got the thing.

Still, for anybody on the net randomly stumbling on this thread, there is something you should learn. If you don't have money, eat less for one month,and do what i did with my Acer get a dedicated card. You never know when you will need it. Because trust me it makes every single difference in this world! It's so worth it.

My Lenovo and Acer have different cpu's but the power and capability is identical. Both incredibly low end cheap computers, but the 20$ dedicated GeForce 810 GT M makes all the difference. it just stops the cpu from doing all the heavy lifting, and it shows in games.
People like me don't want 4k resolution with 120 FPS steady . We just wanna play.
I got Grim Dawn and i wanted to play it with a friend. The lenovo just wont run it (8-12 fps). But the Acer did the trick (30-50 fps steady ). And it's not the first game that actually runs . yes tested for a few hours Dragon Age Inquisition ,last year, very much playable.
Can not stress this enough. A graphics card makes all the difference.

Well, I know software can "flip" the VT switch. Also, Windows can adjust the BIOS time. Set the BIOS tim wrong, go to windows, sync the time and it'll also correct the BIOS time.
