hehe ~ oh so you think i have sophisticated equipment that can read this stuff?
i just used my gf4 4400....
it wont run @ 80mhz AGP, it wont even boot. but it worked just fine @ 160fsb in jumper mode.
went into bios and disabled turbo1 exited and it black screened. (no video)
hit reset, went into bios, enabled turbo1 and it rebooted and ran just fine.
it just took a really picky vid card to prove it.
