    I followed this guide and was successful under 6.10.

    As an unintended side effect, I can now rip a DVD movie 30% faster than before.

    does this improve PCI-E at all?

    YES!!!!!!
    sudo gedit /etc/modprobe.d/nvidia-kernel-nkc

    options nvidia_new NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1

    IT WORKS!!! Yeah............

    Re: HOWTO:Nvidia AGP FastWrites and Side Band Addressing

    Thanks to tseliot for this tip. I can confirm It does work under feisty with nvidia-glx-new as long as you follow scontin's advice:

    sudo gedit /etc/modprobe.d/nvidia-kernel-nkc #and add the line

    options nvidia_new NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1

    The magic bit being _new in the second line after nvidia!

    I'm not sure of the impact on fps as it seems to differ according to how much of glxgears is showing on screen. If the graphic is running but hidden by my terminal window then fps goes up to 2828fps; but if I maximize glxgears to full screen then the underlying terminal records 192fps. As has been suggested elsewhere in this thread the real test will be when you actually play the games

    But hey, the tip works and I now have Fast Write and Side Band Addressing both fully operational

    Thanks

    Would this improve the performance of Compiz Fusion? i.e. make it smoother?

    In game, fastwrite alone jumped my 6800 GT up 200 - 250 fps.

    Re: HOWTO:Nvidia AGP FastWrites and Side Band Addressing

    Works for me(feisty)...more or less with these instructions...I first put options nvidia_new NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1 in /etc/modprobe.d/nvidia-kernel-nkc and that didn't work...so I added options nvidia NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1 after the first line and that worked However I don't know what driver I'm using (don't remember) and I'm using a custom kernel. Still testing to see if any improvements have been made! Also...glxgears gives me fewer points with agpfast write enabled

    Re: HOWTO:Nvidia AGP FastWrites and Side Band Addressing

    Hi! Hoping this thread is still open.

    I run Arch Linux. This distro doesn't have an /etc/modprobe.d directory, much less anything in it. Were would I place the options that ubuntu users place in nvidia-kernel-nkc?

    Arch does have an /etc/modprobe.conf file; that would be my guess, but that's a bit if a shot-in-the-dark.

    Would simply placing:
    options nvidia NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1
    there be adequate?

    I haven't been able to find any reference in my installation that looks anything like:
    alias char-major-195* nvidia

    FWIW: Asus A8V-MX, Athlon64 XP 3500+, GeForce2 MX/400
    The latter item, of course, being the main reason I'm trying to squeeze every ounce out!

    TIA.

    Re: HOWTO:Nvidia AGP FastWrites and Side Band Addressing

    Thank you for the howto. after enabling this stuff, my fps went from

    301 frames in 5.0 seconds = 60.170 FPS
    301 frames in 5.0 seconds = 60.020 FPS
    299 frames in 5.0 seconds = 59.622 FPS

    to

    12332 frames in 5.0 seconds = 2466.249 FPS
    13163 frames in 5.0 seconds = 2632.540 FPS
    13087 frames in 5.0 seconds = 2617.359 FPS


    Much appreciated
