upgraded my video card from an ati 8500 to an nvidia 5500 (pny)
card. the benchmarks all came back w/ stellar results, but for some
odd reason whenever I load a game (wolfet) it just crashes after a
few minutes of gameplay, similar symptoms as what was earlier
described, first I thought the 5500 is a crap card, so I"ll just go
out and get a diffrent one, went out picked up a 6200, still same
results. I returned the 6200, and since i've had the 5500 for some
time, I have decided that I'll just pick up an ATI card for my new
amd system that I will have completed sometime in august. I can
wait till then to resume gameing ;).
the onboard memory on the card is 128, and that's what I set the
apture size for. (btw).
From the Rojak Pot:
Common Options : 4, 8, 16, 32, 64, 128, 256
Quick Review
This BIOS feature does two things. It selects the size of the AGP
aperture and it determines the size of the GART (Graphics Address
Relocation Table).
The aperture is a portion of the PCI memory address range that is
dedicated for use as AGP memory address space while the GART is a
translation table that translates AGP memory addresses into actual
memory addresses which are often fragmented. The GART allows the
graphics card to see the memory region available to it as a
contiguous piece of memory range.
Host cycles that hit the aperture range are forwarded to the AGP bus
without need for translation. The aperture size also determines the
maximum amount of system memory that can be allocated to the AGP
graphics card for texture storage.
Please note that the AGP aperture is merely address space, not actual
physical memory in use. Although it is very common to hear people
recommending that the AGP aperture size should be half the size of
system memory, that is wrong!
The requirement for AGP memory space shrinks as the graphics card's
local memory increases in size. This is because the graphics card
will have more local memory to dedicate to texture storage. So, if
you upgrade to a graphics card with more memory, you shouldn't be
"deceived" into thinking that you will need even more AGP memory! On
the contrary, a smaller AGP memory space will be required.
It is recommended that you keep the AGP aperture around 64MB to 128MB
in size, even if your graphics card has a lot of onboard memory. This
allows flexibility in the event that you actually need extra memory
for texture storage. It will also keep the GART (Graphics Address
Relocation Table) within a reasonable size.
