Is there any way of turning off the shared memory option for graphics cards, I have a 512Mb Radeon x1650 so I dont really see the need for Vista to use 255Mb of my system memory for the graphics. As I only have 1Gb of ram at the moment, I need as much allocated to system resources as possible because Vista is using 65-80% of my ram all the time, and this is a fresh install.

You should be able to go into your BIOS and shut off the shared memory, though in my experience, if you have a standalone graphics card plugged in, the shared memory doesn't get used, thus you have 1 GB of usable memory.

Vista uses a lot of RAM as it is, anyhow. Unless you don't plan on playing games in the future, I, and the rest of us here at Hardware Analysis, suggest you upgrade to 2GB or 4GB of RAM. :~

Ive check in the bios but theres no option in there for shared video memory. I will be going to at least 4Gb of ram when i get the cash, maybe more as i have a 64bit cpu and edition of vista and my mobo supports upto 8Gb, but i would really like to disable the shared memory, is there a reg key i could change at all?

I'm curious if there's a way to disable this as well. My Dell laptop insists on using 191mb of my total 1gb system memory as shared system memory. The laptop has a Radeon Xpress 1150 with 128mb dedicated memory for itself. The BIOS also doesn't offer any options to disable this either.

I don't use it for anything more than various office software and the occasional movie watching; but i'd be a bit more comfortable knowing that i had more available for desktop apps personally. That is unless Vista requires that much video memory to look pretty.

Yeah, my laptop has the same specs, its a Gateway mt6451 and all id like to do is play Warcraft on it. The video is a radeon xpress 200m with 128 dedicated and I tried setting the interface to the plain original windows look and disabling all the special effects but it doesnt help either. My main question is the same and I was hoping to reduce the shared video memory. This laptop only supports vista and at the moment I can't afford to up the ram (using a gig of ddr2 why should I have to up it?)

If anyone can give me any type of solution (even if they are a little drastic ;) I am willing to work on it. I'm getting desperate to lower ram usage even when its idle it runs at about 45% :(

Ricky and William:

You cannot disable shared video memory, unless you have a separate video card in a PCI/AGP/PCI-e slot. Since the two of you have laptops, there's really nothing you can do. If you were able to disable that, in theory, you would have no video at all. However, you might be able to at least lower the amount of memory. This is, again, in the BIOS, and will vary from model to model.

So those of you with laptops with shared memory, you're pretty much stuck, I'm sorry to say. Desktop users can buy and install a discrete (separate) graphics card, and this will disable the need for onboard/shared graphics.

I've got a 6600GT 128MB in my desktop and that's showing 255MB shared memory as well as the 128MB onboard. I can't seem to find a way to disable this either.

Hey guys. I have the MT6451 for about 2 months now. First I will tell you that Gateway has this BIOS locked down and you cannot go in and change graphics aperture size. Been there and done that and got the tshirt from Gateway Tech to prove it...
:) Secondly If you have this Gateway laptop I really suggest adding the extra 1gb of ram. It helped out tremendously. After some tweaking of startup and unneeded services my computer idles at 34% Physical memory with Firefox, Outlook 2k3 and a couple of folders open. When I start up I get about 25% memory used. Also to the guy about your graphics card. It really is an 1150 radeon express and not the 200m. Trust me on this, I went to the ATI website and updated my video drivers to that vista edition and it works great. It wont play the new games but I play SW Empire at War on medium settings at regular resolution with no hiccups at all. Hope this helps out a bit. Peace, Wingsbr

I have a 1 GB video card (GeForce 280) with 8 GB of system, and after a fresh install of Vista 64bit, I noticed that I have 2 GB of ram being shared for the video card. Now, I dont feel I need to use 25% of my system resources for my video card, nor do I need 3 GB of ram fo rmy GeForce 280. I would really like to find a way to disable this feature.

this info is taken from a post on tom's hardware forums, I am aware this is an older topic but it proved extremely useful to me to help me understand that the memory reports as shared but is NOT reserved for use by the graphics controller, it is simply there IN CASE it needs it, but is accessible by the rest of the system. So it differs from "Shared System Memory" being used by a non-discrete graphics solution on a laptop where it actually reserves memory from the system memory based upon a driver or bios setting.



Vista is using a different Windows Display Driver Model (WDDM) than XP (and before) used.



In WDDM, the operating system can accurately account for each of the graphics memory contributors and report available memory precisely through new APIs. The following are some of the clients that use this reporting:
·Windows System Assessment Tool (WinSAT) checks for the available graphics memory and takes the action to turn off or on the Premium Aero Glass experience based on the amount of available memory.
·The Desktop Windows Manager (dwm.exe) is depends on the exact state of the available graphics memory on WDDM systems.
·DirectX games and other graphics applications for Windows Vista need to be able to get accurate values describing the state of the graphics memory in the system. An inaccurate graphics memory number could drastically change the game experience for the user, for example.

Thus, Windows Vista enables the critically important capability of reporting the correct amount of graphics memory to the end-user.

Vista is not dedicating the Shared memory to graphics. This memory can be used by programs if needed, but if the Shared memory is not enough additional to what Vista needs, it will start shutting down some graphic-intensive interface features - such as Aero.

Just do yourself a favor and buy more RAM... shoot for 3GB of RAM with Vista x86, and 4GB for Vista x64.

Core i7 4770K @ 4.4GHz | Corsair H110 | Gigabyte GA-Z87X-UD5H | 32GB 1866MHz Corsair Vengeance

exactly, i would not recommend anybody with vista to restrict memory usage.
vista needs and it needs lots of it.
upgrade ram or switch os or turn off visual features in vista

as far as i know, shared memory options can only be altered in bios
if that option is not available then it might not be possible without altering the bios

You can either be part of the problem or be part of the solution.

I know this is about vista but i have windows 7 64 bit and i have 3gb installed but for some odd reason it says that there is only 2.75gb out of 3gb available. The other quarter is used in shared graphics but i dont need this as i have a Nvidia Geforce GT240 1gb. There are no memory settings or AVG aperature size in my BIOS. I am really not happy with my computer at doing this and i want the full 3gb for my comp. Is there anyway at all to solve this WITHOUT using the bios.

I have been looking on the internet for days and have found absolutly nothing to solve this annoying problem without the use of the bios.

If it helps here is my hardware information:
If none of this is relevant then please do not moan as i am only 15 and have never faced this problem before.

Genuine intel(R) CPU 2140 1.60GHZ (dual core)
Nvidia Geforce GT 240 1GB
Cooler Master HAF 922
Foxconn 945G7MD - 8EKRS2H (motherboard)
3GB DDR2 667MHZ (240pins)
Western Digital Caviar Green 1.5TB SATA II 64MB Cache
Power Supply is 450watts (i think it is but not sure)
Windows 7 Ultimate 64bit
1x blue cold cathode (not sure if this is relivant)

WINDOWS INDEX RATING: 4.5 (determined by lowest subscore)

On a scale of 1.0 to 7.9

Processor: 4.5
Memory: 4.7
Graphics: 6.6
Gaming Graphics: 6.6
Primary Hard Disk: 5.9

I will be very grateful if anyone can help me.

Many thanks,

Connor Lyth

I thought even a dedicated graphics card still needed system memory to operate...Hence why there was an AGP Aperture option in the BIOS's. I'm ready to stand corrected though.

In any case, Windows isn't stupid. If it needs RAM from something that's not using it much, it'll take it.

No dedicated graphics cards dont need system RAM unless you tell it to with shared graphics. Besides why would a Nvidia Geforce GT 240 with 1GB need any system RAM when it has plenty. Thats what i am trying to figure out, why my graphics card is basically stealing it, but without the bios settings to sort out memory or avg aperature size i am left forever searching google. But i am not having any success :( . Without the bios memory settings there is no hope of ever getting it back. >:(
