How to use 4x AGP instead of 8x

[Wizzard]

I have a A8V Asus MB which seems to reboot randomly. I have seen a
suggestion that using AGP 4x instead of 8x may be a solution. How can
I make it to run at 4x please to test this issue?.

BIOS?

In the BIOS, Advanced:Chipset:AGP_Bridge_Configuration.
"AGP Mode" should offer two options, 4X and 8X, for an
8X card.

If you are using an ATI video card, ATI ignores the BIOS
setting. For ATI cards, you use the SmartGART tab and
change the AGP setting there. The setting takes effect on
the next login or reboot.

You can also try enabling "DBI Output For AGP Trans". That
option is manditory in AGP 3.0, so a video card has to support
it. That slightly reduces switching noise when the bus is
transferring data.

For motherboards without a BIOS option to control whether AGP
is 4X or 8X, you can always experiment with Powerstrip from
Entechtaiwan.com .

Here is a sample picture. This is with an older driver package.

I don't think you need Catalyst Control Center to get it (CCC is
a bloated piece of software, that should not be installed unless
you have system RAM to waste). But here is a picture of SmartGart
in a CCC control panel.

Start with your Display control panel, and have a look in
Advanced. I don't have an ATI card in the computers in front
of me right now, to look.

If you right click on the desktop, click on properties, click on
settings, and then click on Advanced you should see a tab labeled
SMARTGART. In that tab is a slider with the available settings.

I wouldn't characterize it as 'ignoring' the BIOS. ATI drivers will
enforce the BIOS settings upon first restart, and indefinitely
thereafter until the device settings are changed via SmartGART
(override).

They didn't for me. When SmartGART first came out, I set my
BIOS to 4X, and SmartGART used 8X. Maybe ATI has seen fit to
give the BIOS some control again, but my previous experience
was, the BIOS was no longer in control. And that is why I
recommend visiting the SmartGART tab, for ATI users, so you
can be sure as to what is being used.
