Q. How can I enable or disable AGP Fast Writes?
Note that in order to enable fast writes both your motherboard and your graphics card must support it. All
GeFosce cards support Fast Writes, but not all motherboard chipsets do. In particular the various versions of the
Intel i815 chipset do
not
support Fast Writes.
There are a number of methods:

Some BIOSes support enabling and disabling AGP Fast Writes in the BIOS setup. If you have a Tyan
Trinity 400 motherboard, you must use BIOS version 1.0 as in later versions Tyan have removed the Fast
Writes option in the BIOS.

If you have a Creative card you can use AGP Wizard. Read more about this in the '
What is and where can
I get AGP Wizard?' question.

You can use the fwoff.reg registry file to disable AGP Fast Writes in Windows 9x/ME - available here:
http://www.geforcefaq.com/files/fwoff.reg
If you ever want to switch Fast Writes back on, you can use the fwon.reg registry file - available here:
http://www.geforcefaq.com/files/fwon.reg

You can use the fwoffw2k.reg registry file to disable AGP Fast Writes in Windows 2000- available here:
http://www.geforcefaq.com/files/fwoffw2k.reg
If you ever want to switch Fast Writes back on, you can use the fwonw2k.reg registry file - available
here:

Disabling Fast Writes may help with instability problems but may also cause 3D applications to run slower.

Q. How can I enable AGP Sidebanding?

Before you read this question:
Don't worry too much if you can't get AGP sidebanding enabled. There's
only about 1-2fps in it and it can cause instability.

If you have a Creative card, there is a utility called AGP Wizard that you can use to enable AGP
sidebanding. You can read more about it in the following question: 'What is and where can I get AGP
Wizard?'.

In the 3.69 and later drivers you can use the athlonsbaon.reg segistry file to enable sidebanding on Athlon
motherboards only - available here:
http://www.geforcefaq.com/files/athlonsbaon.reg
If you have problems after enabling this, use the athlonsbaoff.reg registry file to disable it again -
available here:
http://www.geforcefaq.com/files/athlonsbaoff.reg
WARNING:
The registry file may not work if you have a 64MB Prophet II card. It seems that AGP
sidebanding is disabled in the video BIOS for Athlons with that card. In addition you may not be able to
use AGP Sidebanding if you have the Athlon AGP2X hack enabled as well in the 5.xx drivers.

If you have an ASUS card, you can download a special Flash BIOS file that will enable sidebanding from
the ASUS website.

If you really like living dangerously, it is possible to change your BIOS file before you flash it so that
sidebanding is enabled. However, this will
invalidate your warranty
, and could in theory mess up your
