How to use system memory as vga memory

by brian In reply to How to use system memory ...

Video Memory typically runs much faster than ram. There are configurations where the memory is shared but the performance is degraded by the fact that the RAM is a slower memory and because of its proximity to the video processor. THe data has to go through the PCI bus which only carries it at 33mhz. It can travel faster with the AGP cards but there is no substitute performance wise for the high speed video memory on the chip.

Your card is not designed to use system memory so even if you could get it to do that, I doubt it would improve performance.

If your card is PCI, then, NO. You can't share system memory with it.

If you have an AGP card, then the answer is maybe.

Start by makeing sure that you have the latest AGP mini-port driver for the motherboard installed.

Then, install / update directX (check with the video card Mfg for which version the driver supports)

Then, install the latest driver for the video card.

Finally, shut down, and restart the system.
Enter BIOS setup, and locate the AGP settings section. Adjust the AGP apperature to either 64MB, or 128MB.

If the drivers are written properly, and the hardware supports the functions, your VGA card will share system resources as needed.

Hi,

Got your message.

The "AGP Mini-port driver is one of the "software" drivers for your
motherboard / chipset.
If you need help identifying who made your motherboard, or what chipset is
on it, try the tools link at www.motherboards.org
One note of caution: verify the speed of your video card. If it is only 1X
AGP, do not install the AGP driver in a faster mode, or you will have system
conflicts.

As to the amount of video memory;
Windows only shows you the physical ram on the video card, not all memory available to the video card.
Increasing the size of the AGP aperture allows applications to share some of
your system ram with the video card as needed.
As such, you will never see an increase in the amount of video ram shown.
The shared system ram used for the video acts like a buffer, preparing the
data for the next screen while the video card is processing the current
screen.
NOTE: Allocating more system RAM to video functions is NOT the same as having more memory on the card.

For some systems where the graphics chip is built onto the motherboard, you
can change the amount of physical memory that is assigned to the graphics
chip.
As another peer posted, the video ram is always faster than the systemram.

For drivers for the S3 Trio, try www.s3graphics.com
S3 has changed hands a few times over the past couple of years, and is now
owned by VIA.
If they do not have an XP version of the driver, that means that the native
XP driver is all that you have.

I have seen some very good graphics cards selling for around $20 -$30 at
e-tailors.
