AGP Aperture size and GeForce lockups

[DevOXide]

Hi all !

Any gurus here who can solve this one ?

I have read several places about what size the AGP Aperture size (in bios) should be set to. (Most recomend 64Mb). I have tried all (4, 8, 16, 32 Mb). When i reach 64 and above, everything locks up when I try to start a game.

Anyhow this is my prob.:
When i set the size to 64Mb or more, my card/copmuter completely locks up when I try to play any games or run 3D Mark 2000.
In addition I seem to get the best performance with 16Mb, rather than with 32....????

My HW spec:
- P2 350, Aopen AX6BC Motherboard
- 256 Mb RAM
- Asus V7700 GeForce 256 GTS with 64Mb
DDR ram.

It does not matter if I use the NVIDIA reference drivers or Asus's.

Anyone have a workaround or know why this is happening ?? Or maybe I should just leave it at 16Mb or 32Mb ?
Does this have any performance significance over using 64Mb and above?

I would be very glad if someone could help me out here...

Best regards

I have read that aperture size should be half of installed ram.
It's crap.
I have read that power wattage plays a part, and I believe that to be crap too.
Then there's the thought about running the fan to cool the chip on a oulet away from the video card and somewhere on the motherboard.
And that can go into the crap bin too.

My Geforce will work in opengl and direct3d only in 16bit mode where there is no real video card strain ( on fast setting not quality ).
To me, the best bet is to increase voltage to agp bus if possible. I can't change mine with an abit bx6r2 board, but when the voltage drops below 3.2 (as against 3.3 normal for agp), from reading motherboard monitor, the video card crashes/ locks up.
This is a fact, and the only true fact I have experienced from the card.
I hope this helps, as I find it is little comfort to buy a video card and then maybe have to buy a new motherboard too.
Good luck

Just set it to whatever works best for you and don't worry about it. Since your card has 64Mb, it is doubtful you will ever use AGP memory paging anyways.

Try tweaking your Bios like fastwrites disabled,check memory timings etc,I run mine at half the size of total ram(64mb) with no problems the only problem I had was on the first day with my new board, the memory timings were wrong in Bios ,once I corrected this no problem with games at all, anyway you have loads of memory on your card so just set it to 16mb & be happy as Rickr as stated you will not need more then that.
