I have the manual for that on my K: drive.

E7093v1.6.pdf

ATI RS480/RX480 Chipset
ATI SB400 Chipset

There is no sign of the x32 RAM chip that was added
externally to the Northbridge on some later ATI/AMD
designs. So all the memory used by the graphics, comes
from system memory.

The manual has a few things in it, that seem irrelevant
to the design.

In Advanced Chipset Features, you will find

    UMA Frame Buffer     [64M, 128M]
    AGP Aperture Size    [64M]

PCI Express graphics should not have an AGP GART, in which
case such a setting would be ignored. The purpose of AGP
GART setting, is to define a linear region of the address
space, for translations. It allows physical memory gathered
from various places, to have a linear address defined for it.
So the AGP GART is *not* a direct usage of memory. It's
address space. Now, on a 32 bit OS, with a memory license,
defining a large GART chews into the available address space,
so such a setting could have an impact on a 32bit OS with
4GB of RAM present. You would get less than "3.2GB free"
if the GART was actually being used. And my experience was,
that large GART settings seemed to destabilize the computer.

The UMA is the one you should pay attention to.
It only has two options. That's where your RAM went.

The manual also mentions "UMA+sideport", but I don't
see the sideport x32 RAM chip in the motherboard diagram.
The sideport chip was really a "hood ornament", because
it isn't fast enough to "accelerate" the performance
of the video. The reference to "sideport" appears in
only one sentence in the manual.

I cannot see a sideport chip in this picture either.
