Not recognizing shared video memory

I have a SiS M760GX Mirage 330 AGP 8x graphics card that has 32 MB of
onboard memory, but it can be configgured to have up to 128 MB of video
memory because I have shared RAM. It came preconfiggued with 64 MB of video
memory, but that was not enough, and I read that I could change the amount
of video memory in the BIOS. So I changed I to 128 MB of memory. When I go
into the adapter tab of the SiS M760GX properties window, it shows the
adapter as having 32 MB of memory. I went back into the BIOS, and it said
the card was set to have 128 MB of memory. Before, when it was set to have
64 MB, SiS M760GX properties window showed it as having 64 MB. If I open
EVEREST Home and look GPU under the display category, it says the card has
128 MB, but if I look in the Windows Video category, it shows the adapter as
having 32 MB. I recently reformated and reinstalled windows, and at first
the SiS M760GX properties window showed the card as having 128 MB of memory,
but now it shows it as having 32 MB.
 
shared video depends on the amount of ram you have the more ram the higher
the shared video can be set
 
Is this an ACER Aspire 3000 notebook..? What computer make & model is it..?
The SIS M760GX is the mobo chipset, right..? Is the graphics integrated on
the mobo..?
May only have 64 meg shared..

Yes, the card is integrated into the motherboard

All the info about my computer is right here. Baiscly you were right about
everything, but the card is AGP 8x. I have 1024 MB of RAM, so I don't see
why 128 MB of video memory should be a problem.

Matt,

I think your onboard graphics is 64mb or 128mb shared (see link above) and
should be set in the BIOS accordingly, is this an AGP aperture setting or an
actual shared mem setting..? The shared mem is coming directly from your
system RAM, 64mb + onboard video ram at 64mb = 128mb total available for
graphics.. Windows may see it differently than Everest or an Acer system info
app.. If the onboard graphics has 64mb shared then 32mb would be allocated
from your system RAM. If you can run it at 32-64mb without a problem then you
could be getting, set at 32+32=64mb shared, or set at 64+64=128mb shared
automatically allocated from your 1024mb system RAM (either 32 or 64mb only)..

You should read through these posts and try to come to your own conclusion..
