can I use a radeon 7000 or 9000 dualhead on old AGP1X?

[dave]

my PC is an old vaio 2.66 ghz P4 running XP home SP2. it has only "old"
agp version 1. got plenty of RAM though.

can I use -either- of the ATI dualhead cards in the header? ATI site
info on both cards infers they 'require' at least AGP2X near as I can
determine anyway. maybe there's -other- ATI dualheads I should use I'm
unaware of?

what're the implications if I DO buy & stick a 7000 or 9000 card in
there? anybody tried it? 'best guesses' also welcome, at this point :-/.
I only do lightweight photo edits and simple site development on this
machine, NOT a gamer.

ps-monitors I want to run are the old original sony 17" LCD, and a 21
inch sony/dell flatface CRT. later, I'll get an additional PCI card
(hopefully also ATI) to run ONLY the sony LCD, and have the radeon
dualhead driving a 21" CRT 'on both sides of the LCD' (3 monitors total).

pps-do either the 7000 or the 9000 card offer refresh rates SLOW enough
for the LCD? I think it 'wants' something like 80....maybe even slower? :-/

ppps-if I -can't- run either the 7000 or the 9000 card, I'm wide open
for alternate dualhead card suggestions from you guys

thanks for tips and clues

Nope. There are no P4 chipsets that have anything lower than AGP 4x...

Yes, both Radeon 7000 and 9000 run fine in AGP1x. But since you have at
least AGP4x no AGP Radeon or AGP Geforce will be a problem...

You can put a screwdriver in an AC wall receptacle but it's not a good idea.
AGP X among other things represent voltages. The card and M/B have to be
compatible. I have P4 Intel motherboard with 2.4GHZ CPU. This M/B is 2X/4X.
P4 and standard AGP would be quite a mismatch. IOW verify the specs for the
M/B.
Their was just a thread on running 3 monitors but don't recall the outcome.
Look for it in google>groups.

P4 means at least AGP4x or better, and _every_ Radeon and _every_
Geforce is a _perfect_ match for every AGP4x mainboard.

The problem you describe was apparent with much older cards only
(Rage128 etc, all pre-Radeon/pre-Geforce aera).

I can read specs. Not so sure about the OP.I've used both 128 & 9600 in this
P4 M/B.
Except possibly for sex, sticking something in to see if it works, is
usually a bad idea.

Which doesn't change a yota on the fact that there are no voltage issues
with any Radeon or Geforce cards, only with a few much older cards that
are now almost a decade old and hardly something anyone wants to use any
more...

So your saying any Radeon can be put into an AGP slot on any motherboard?
You've said his board couldn't be 1X. I doubt that it is but don't know for
sure. If someone wants to take your word for it that's fine with me.

Basically yes. All Radons/Geforce with native AGP interface have at
least an AGP4x interface and are compatible with AGP 1x, 2x, 4x and 8x
(3.3v and 1.5v).

The only exceptions are AGP cards that use a GPU with native PCIe
interface and an AGP-PCIe brigde. These bridges usually only support
1.5v and 0.8v (AGP4x and AGP8x), but since the voltages are coded into
the connector correctly these cards won't fit mechanically in an AGP
1x/2x slot.

The voltage issue where cards were coded for AGP 4x but didn't support
the 1.5v signallong voltage is dated before the begin of the
Geforce/Radeon aera. Cards that fall under this issue use GPUs like ATI
Rage128, Nvidia RivaTNT, SiS 650, Matrox G400 and other cards that
precedes the aera of cards with hardware T&L (Radeon, Geforce, Volari
etc). These cards often are incorrect keyed and can destroy a mainboard
with 1.5v chipset.

You've said his board couldn't be 1X. I doubt that it is but don't know for
sure.

I'm sure, simply because there is not a single chipset for the P4 that
only does AGP1x or AGP2x. All P4 chipsets, even the oldest ones (i850,
i845) are AGP4x already and use 1.5v signalling voltage. Besides that,
AGP4x is older than the P4 (AGP4x was already apparent in the P3 aera).
