agp aperture setting

I was having a problem with Doom 3 and also The Sims 2. Doom 3 would get to
the main screen and the mouse would be frozen in the upper left corner. The
Sims 2 had numerous random crashes, rebootings and slow choppy graphics.
After numerous bios related troubleshooting I have now found that the
aperture setting of 4mb recommended by evga was the culprit in both games. I
reset it to 64mb and all is now well. Is it a misprint in the manual? I seem
to remember the same recommendation on the evga sites bios recommendations.
Any others with this problem? Thanks.

Pretty commonly it's recommended to set the aperture to half the system
memory size, or equal to the video card memory.

AGP aperture setting doesn´t matter much if is set min. !!!! to 32Mb &
if the videocard has its own memory (not MoBo integrated & w/o it).
Time ago I experienced same problem passing from w95B to W98se, since
before worked perfectly (was Agp1x only hardware accelerated in Win95B
that time on my machine & had setting of only 16Mb; I experienced same
crashes until I set it to 32Mb; looks that nVidia drivers require this
setting as minimal!)

Aperture setting should not be set any smaller then 32MBs.

Word amongst most BIOS guides is that setting AGP aperture to less than 32
MB automatically disables AGP functions altogether.

Setting it that low essentially turned off your AGP bus functionality.
That's why you were getting crashes. So, likely, that was a misprint you
originally read. Common suggestions are to set AGP Aperture to 64 or 128
.... doesn't ultimately matter which. The more VRAM your video card has, the
less the aperture comes into play. The advice of "1/2 your system RAM, or
equal to your video RAM" that is commonly seen is erroneous.

Interesting. How so?

Thanks for all the replies from everyone. I e-mailed evga tech support, and
just got their reply. It seems that the 4MB setting is for
"troubleshooting"! I'm not a guru, and when the manual and the website state
the recommended bios settings to use for the card, they should state what
makes the freakin card actually work!! I don't know what problem they are
talking about troubleshooting by effectively disabling the AGP bus
functionality, but I guess I won't worry about that. Again, thanks.
