G400 AGP Aperature Bios Setting?

[cshaws]

I was wondering what setting I should have on in my bios for my G400
64 or 256 or does it matter?

Thanks for you input

Depends on the amount of RAM you have. I have 128Megs and my aperature size is set to 128. Works great for me.

It does depend on the amount of RAM you have, but setting it as high as possible always works. It will then use all the available memory for textures. I have 256 Mb and set it to 256Mb long before, even when I had 32Mb RAM floating around my pc.

Some mobo's need the highest setting to get the G400(Max) working okay.

Hi, I just bought a G400 SH myself and I can´t seem to get it working. Now I was told to change the AGP Aperture as well. One thing that makes it difficult is that I don´t kwow where and how to set those values. can anyone help me out as you have just done this stuff. You would definetely make me a happier human being.
Thanks !

Hermenr:

How old is this machine? I think with some older AGP boards using the 440LX chipset, there may not be aperature size settings in the BIOS (I could be way wrong on that though).

Some motherboard do not have the Aperture open. Gigabyte, for instance, will not open an AGP aperture unless you set the Video RAM to "Cacheable" or "Write Protect". There is no numeric aperture size adjustment on Gigabyte boards like there are with many other mobos - it either is or isn't. Award makes a BIOS chip for their supported motherboards that will give you this capability for $24.95 USD. Another thing: Make sure you enable the Video BIOS to be "Cacheable" or "Write Protected" (Depending on your motherboard/chipset/BIOS maker) as well, it will help the board work more smoothly.

Hermenr, you set the AGP Aperture size in the BIOS of your motherboard. So you might want to press Delete repeatedly upon booting your PC (or any other key that lets you into the BIOS) and look for a setting called AGP Aperture Size or something else with AGP with a number behind it. Probably set at 64 at this moment (standard).

Change this number to 128 or 256 if your BIOS can handle that. Save the changes and reboot the PC.

Thanks for the quick reply (never tried a forum before and it does look like an effective medium). I went into BIOS yesterday and strange enough... I couldn´t find anything with AGP in there. FYI I have an IBM Aptiva PIII that had a Creative Labs 8meg VCard before.. also in the AGP slot.
