Hi - I need to buy a good 512mb AGP 8x card for my motherboard but it does
not mention any size for the card , I have looked in the bios though there
is nothing as I am using onboard at the moment, I have a GA-8S661FXM-775
board the manual I got from the Gigabyte site has no mention of it but Paul
from an earlier post about my question for a Ram question posted this site:

I see on page 29 there is "AGP 8x 2 GB" that is all the info there is for
this..... I dont know but would this card support 2GB??


Thanks, GK

The AGP interface comes in speeds, of 1X, 2X, 4X, 8X.

The 8X was as fast as it gets.

The RAM chips on the video card, provide a place for
texture storage while the GPU on the video card, prepares
a picture. Typical cards might have had 512MB or 1GB
of RAM on them. That amount of RAM isn't a motherboard
issue, since the motherboard doesn't directly control it.
The GPU owns the RAM chips on the video card.

When the BIOS posts, it prepares a memory map for the system.
All the RAM is addressable, so the sum total of system RAM
(DIMMs in the motherboard) plus video RAM chips on the
graphics card, need to be addressable. On the Windows OS,
there is an addressing limitation with a 32 bit OS. A 64 bit
OS has less of an issue with addressing.

I have 4GB of motherboard RAM on the machine I'm typing this
on. The video card has 512MB of video RAM. Of the DIMMs on
the motherboard, I can only get about 3GB of system RAM to
show up, as my 32 bit OS needs some room to address the video
card. 3GB + 0.5GB is slightly less than the 4GB addressing
limitation.

If I were to buy a video card with 1GB of video RAM on it,
then Windows would report that the available system RAM had
dropped to a value less than 3GB. And that's because there
are no addresses available to access all the hardware.

There is more info here, on mixing motherboard chipsets and
video cards. Have a look at this first, and then come back
with more questions.

If I used this card with 1GB of video RAM, it just means
my 32 bit OS will report less system RAM is available. With
cards like this, you want to read the customer feedback
comments regarding video card drivers, because sometimes
the drivers for AGP cards, are a gating factor to enjoying
your new purchase. The drivers just don't have the level
of support that they should, and sometimes, there's only
one "good" driver version to use.

AGP, working AGP that is, is luck considering it's 10 year old
technology. I used to drive an old C10 Chevy van until some lady,
after sliding sideways half a mile, t-boned the front end with her
newer Nissan. So reliable for popping out every window in her car to
the very end, including her eyeballs. I might be driving it still
today if she hadn't put me out of my misery and into a car lot for a
newer pickup, but I'm also running a 64M AGP Radeon on this computer
with a perfectly empty PCI-E slot on the other, across the room.
Sometimes there's no getting round that these things just really take
a lot of figuring out.
