I'm using an intel chipset G41 express in my pc but I don't know why each time I change my system, my graphic memory(1G) used decrease , first 700mb with win7 64bit and now it's became 256

Hello the manual can be downloaded here:

http://www.gigabyte.com/products/product-page.aspx?pid=3471#manual

Adobe reader, is needed to read the content.

My advice is to install a better graphic card, on the mainboard.

The mainboard has PCI-e socket.

This will give a much better performance.

ATI/AMD makes very good graphic cards.

Good luck

You could increase to a 1000Gig's if they made one.

A graphics card has it's own graphics processor, and graphics ram memory. It runs independent of the System Resources.
The Processor and Ram Memory.

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

http://en.wikipedia.org/wiki/Integrated_Circuit

The graphics I.C., or graphics chipset, is a GPU,

http://en.wikipedia.org/wiki/GPU

A GPU can be mounted directly to the motherboard, and use some of the system resources. Integrated graphics.
Or it can be mounted to a removable graphics adapter card.

IF there IS a 'bottleneck', it will be your Processor, and amount of Ram Memory.
Should have at least 2GB of ram memory
It will take up to 4GB. can also support DDR2 Sdram at 667MegaHertz. (PC2-5300)

Intel 945G motherboard chipset.
Intel 82945G Northbridge chip,
Intel 82801GR Southbridge chip. (ICH7R)

Supports Intel Core2 Duo processors, with a Front Side Bus of
UP TO 1066MegaHertz. (FSB up to 1066MHz)

Intel 945G chipset was brought out in 2005. This means to me, the PCI Express technology used on your motherboard, is
PCI Express 1.1

I would stick with the graphics cards using PCI Express 2.0 technology.
I've read reports where the PCI Express 2.1 cards, weren't 'playing nice' with motherboards using the PCI Express 1.1 technology.

Unless you just wanta' experiment? Who knows?

How many maximum Watts is the Power Supply, capable of delivering at 80 percent, and how many Amp's does the 12 Volt power rail have?
(If there is more than one 12 Volt power rail, you can add together for the total 12 volt Amp's )

See what the minimum requirement is for the Power Supply. make sure you have MORE than enough.
Also if the graphics card requires an additional power cable; make sure your Power Supply has it.

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=555358&CatId=3669

But the minimum wattage for the Power Supply is 450 watt.

http://www.newegg.com/Product/Product.aspx?Item=N82E16814129203

Power Supply? 500 Watt.

I don't see any VGA drivers listed for any of the Windows 7 versions,

http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Desktop+Boards&ProductLine=Intel%C2%AE+945+Express+Chipset+Family+Boards&ProductProduct=Intel%C2%AE+Desktop+Board+D945GCCR

Guess they felt the drivers in the O/S (Win7) would support the Intel 945GC chipset, and it's Integrated Graphics. (Intel GMA 950)

Product Guide, (Motherboard manual), download link,

http://www.intel.com/support/motherboards/desktop/d945gccr/sb/CS-024514.htm

Intel 945GC chipset info,

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Core_2_chipsets

IMHO the next course of action to take, would be to buy an economical PCI Express graphics card, and install it in the
PCI Express x16 expansion slot, on the motherboard.

It will have drivers for Win7.

[Driver: A small piece of software that allows the Operating System to communicate with a device.

Win7 is the O/S, and graphics chipset is the device ]

Something as economical as this example, will work,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2759376&CatId=3585

[NOTE*
The Intel 945GC came out in the first quarter of 2007.
According to what I read, the launch date was the first quarter of 2005.

Don't know what transpired in the meantime. Maybe Intel didn't release it until it had PCI Express 2.0 support.

At any rate..........

PCI Express is a technology.

The first release under the PCI Express name, was the
PCI Express 1.0 version.
Year? 2004.

Next upgrade version was PCI Express 1.1
The version after that was PCI Express 2.0
Year? 2007 (January 15, 2007)

I don't know if the 945GC chipset on your motherboard, uses the
PCI Express 1.1 version, or the PCI Express 2.0 version.

The graphics card is based on the PCI Express 2.0 version.

Does it matter? NO
Why?
Because PCI Express 2.0 is Backward Compatible, with
PCI Express 1.1

In otherwords the PCI Express 2.0 graphics card WILL work, on a motherboard based on the PCI Express 1.1 technology.

Will you get the full capabilities of the PCI Express 2.0 graphics card?
NO

Will you notice?
NO

PCI Express 1.1 technology has a PER lane data rate of 250MegaBytes per Second. (250MB/s)
A transfer rate of 2.5GigaTransfer/s per Second. (250GT/s)

PCI Express 2.0 technology has a per lane data rate of 500MB/s.
A transfer rate of 5.0GT/s ]

Click on the link below and choose the operating system you need your drivers for. Then choose the Audio Driver (Audio: Realtek* High Definition Audio Driver) and the Graphics driver (Graphics: Intel Graphics Media Accelerator Driver for G41 Express Chipset)

1) It has an Intel G35 Express motherboard chipset,

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Core_2_chipsets

Under the - Chipset heading on the left, scroll down to - G35

Note that under the - Graphics heading, all the way to the right, that the Intel G35 Express chipset;

1) Will support a PCI-Express x16 expansion slot. This means a PCI-Express graphics card can be used, IF, there is a PCI-Express x16 slot on the motherboard.

[ PCI-Express is a technology. The current PCI-Express technology is PCI-Express 2.0

There is a PCI-Express x1 expansion slot, and a PCI-Express x16 expansion slot. (Not relating to Your computer at the moment)

The PCI-Express x1 slot is Not used for a graphics card.
The PCI-Express x16 slot IS,

http://en.wikipedia.org/wiki/PCI_Express ]

2) Has Intel GMA X3500 Integrated Graphics.
Meaning if there is NO graphics card installed right now, the computer is using Integrated Graphics, (Intel GMA X3500,

http://en.wikipedia.org/wiki/Intel_GMA#GMA_X3500

Now,...you are essentially working on a laptop with a touchscreen.
Once you remove the 10 screws from the Back Cover, and remove the cover, you are looking at the exposed circuitry of the computer.

You NEED to follow Anti-Static Precautions. This cannot be performed as on a regular desktop computer. Touching the metal frame (Of the unplugged from power computer) will do you No good.

You need to use an ESD wrist strap, and connect it's alligator clip to a good ground source. [ Electro Static Discharge]

Your body carries Static electricity. Static WILL fry out (Short Circuit) the delicate hardware components inside a computer.

With the Back Cover off the manufacturer knows all of the hardware components are exposed. This means the person working on the computer should be aware of Static issues, and use proper tools.

The average consumer is not aware of this. This is why only a ram memory upgrade is recommended by the manufacturer. (Before they went out of business)

This is why there are no service manuals released, also.
Only for the qualified authorized service techs.

So,...let's look together. See if there is a PCI-Express x16 slot, for one.
It can be any color. Will be longer than any other expansion slot on the motherboard. The PCI slots (Usually white) are not as long.
(164 contact pins. 82 on each side)

These examples of a PCI slot, and versions of a PCI-Express slot, are all the same color. (Yellow) Not usual for a desktop computer.

http://en.wikipedia.org/wiki/File:PCIExpress.jpg

The top example is an example of a PCI-Express x4 slot.
Hardly EVER used, I didn't mention it.
Has 64 contact pins. 32 on each side.

The next slot down is an example of a PCI-Express x16 slot.
164 contact pins. 82 on each side.

Next down is an example of a PCI-Express x1 slot.
36 contact pins. 18 on each side.

Next down is another example of a PCI-Express x16 slot.

Last example is an example of a PCI slot. TOTALLY different technology than PCI-Express.
124 contact pins. 62 on each side. (Unless PCI that is 64-bit)

IF, there is a PCI-Express x16 slot on the motherboard, you can use PCI-Express 1.1 or 2.0 graphics cards.

You need to be concerned with;

A) How much height is available for the graphics card, and how much length? Check the measurements inside the computer. Match to dimensions of the graphics cards you are looking at.

B) How much POWER does the graphics card require? It's in the Minimum Requirements stated for the graphics card.
How much power is available to the all-in-one computer?

This could be an instant stopping block.

AMD ATI Radeon graphics cards generally use less power, than a comparable Nvidia graphics card.

C) Worried about your computer per se uses DDR Sdram ram memory, and the graphics card uses GDDR3 ram memory? (Just an example. Not directly related to Your computer)

Don't be. Doesn't matter what graphics memory a graphics card uses.

The graphics card does Not rely on the system resources (Processor and Ram Memory) of the computer.
A graphics card has it's own Processor, (GPU. Graphics Processing Unit), and graphics ram memory.

Referring to a Toshiba Satellite Pro L300 series of Notebook PC:

According to the Service Manual;

1) The Maximum Total Amount of Ram Memory depends on the Northbridge chipset used.
(System Controller. Intel)

If it is an Intel GM965 chipset, the maximum total amount is 4GigaByte. (4GB)
If it is an Intel GL960 chipset, the maximum total amount is 2GB.

Northbridge chipset (Or System Controller)

The Northbridge chipset was aptly named so, because of the general location of the chipset on the motherboard.
It is generally located under the Processor.

(The Southbridge chipset is located further 'South' on the motherboard)

The Northbridge chipset handles the faster capabilities of the computer.
It handles the Processor, Ram Memory, and High-Speed graphics.

High-speed graphics being AGP or PCI-Express.
Integrated Graphics, or a graphics card installed into a PCI slot is NOT high-speed graphics.

This is handled by the Southbridge chipset.
The Southbridge chipset handles the slower capabilities of the computer.

Motherboard diagram;

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

Information on the Northbridge (computing),

http://en.wikipedia.org/wiki/Northbridge_%28computing%29


Information on the Intel GM965, and GL960 chipset,

http://en.wikipedia.org/wiki/List_of_Intel_chipsets#Core_2_Mobile_chipsets

Look under the heading Chipset at GL960.
Looking across you can see that the chipset supports;

1) DDR2 Sdram that is either 533MegaHertz, or 677MHz. (SO-DIMM ram memory for laptops)
2) Supports up to 3GB

[ Your laptop has TWO ram memory slots. The primary, or Main ram memory slot, (Outside edge), and the Optional ram memory slot, (Inside towards the middle)

There are No 1.5GB ram memory modules. ('Stick')
This is why 2GB is the maximum with the Intel GL960 chipset.

Install one 2GB ram memory module in the Main ram memory compartment,
OR,
Install one 1GB ram memory module, in the main ram memory compartment, and one 1GB ram memory module in the Optional ram memory compartment ]


Now look under the Chipset heading at GM965.
1) Supports DDR2 Sdram at either 533MHz, or 677MHz.
2) Supports up to 4GB.

How to know what Northbridge (System Controller) chipset your laptop uses?

Intel Integrated Graphics will give decent resolution performance but is not an optimal graphics.
Ensure you are using the optimal resolution 1366x768 pixels. Using a lower resolution will give you a unsatisfactory display.
If you still don't like the graphics, you may need to add an expansion video card.
