NF7-S mother board and POWERCOLOR 9700 crashes at 8xAGP

hi, I discovered what is causing game crashes, now I need to know why my
NF7-S motherboard and my Powercolor Evil Commando 2 9700np graphics card are
incompatible at 8xAGP

in 8xagp mode with fast write on (the manuals for nf7-s and 9700 state they
are compatible with these modes) my pc passes all directx tests and windows
3D screensavers work, but games in particular crash before they even run,
freezing up my pc and turning my monitor off. turning "fastwrite" off makes
no difference, running games still freeze my pc. going into the bios and
turning my agp to 4x and doing the same in the ATI control applet fixes this
problem.

so how do I run my pc at 8xAGP? is there some technical incompatibility?

You could try upping the AGP voltage a notch, My NF&-s seems to
undervolt everything else slightly. Also, is the power supply
adequate?

the power supply is a 380W antec true power, I am sure that is ample. but
what agp voltage do you use? I haven't done this before and I don't wanna
fry things. the nf7-s is great for this kind of thing though!

You've got an AGP 8X mobo and VC so you should be able to run at 8X.
However, when it boils down to it the performance at 4X *should* not be that
poor compared to that at 8X - and you've still got an excellent card which
ever way you look at it :o)

FWIW I didn't experience any problems with an NF7-S and Sapphire 9700
non-pro and 8X AGP (with an Antec Truepower 330 W PSU) although I never
bother with Fastwrites enabled, I'm not convinced there's much of a
performance boost gained by enabling this.

I have my AGP at 1.6 volts. The only reason I upped it is because I
has some weird crash in BF1942 secret weapons (the only prog that
would crash), so I upped the AGP and the Chipset voltage to fix it.

excellent, I will try changing mine from 1.5v to 1.6v and see what happens.

hmmm, turning the voltage alone to 1.6v didn't have any problems, playing a
game at this voltage was fine. I rebooted and set the agp rate to 8x crashes
the computer after the POST.

you said chipset voltage, what did you use? I haven't adjusted that.

YAY, I fixed it, I had to install the Zalman ZM-80C-HP and now I can enable
8xagp with fast writes on. I played Jedi academy at full tilt with no
problems at all (maybe some screen tearing though, anybody know how to fix
the screen tearing? turn on v-sync?
