AGP or AGP2

[Ken Spencer]

My system is a P4 2.53 on an Intel D845PEBT2 board.

The instructions with the board says the board only supports 1.5 v AGP
2x/4x cards, but not 3.3 v cards. Does this mean I have AGP or is it
AGP 2?

Thanks,

Ken

One nice thing about PCI-e video is that it's relatively
straightforward. I've never been able to figure out all the weird
marketing crap that came along with AGP. It was just one screwy
thing after another.

The voltage thing is hosed too. They just couldn't name or make
anything simple and clear.

As far as I know there is no "AGP" and "AGP 2", at least not the way you're
specifying it. There's AGP 1x, 2x, 4x and 8x, and voltages running between
3.3 and 0.8. Generally the 3.3V cards are the least compatible with
anything. The slots and cards are supposed to be keyed so you can't plug the
wrong voltage into a slot, but I hear some 3.3V cards didn't follow the keys
properly and can be plugged into a 1.5V slot... thus damaging certain
motherboards. Basically if your card is AGP 4X it will be safe for your
motherboard, but if it's 2X there's a risk it might be 3.3V.

Then of course we can get into the whole short-lived "AGP Pro"
specification...

The AGP slot on your board is revision 2.0

Per Intel's web site

What add-in AGP cards can be used?
The D845PEBT2 AGP socket can accept universal AGP cards that comply with the
AGP 2.0 specification. The D845PEBT2 can use 1X / 2X / 4X card(s) operating
at 1.5V.
Note: Legacy 3.3V AGP cards are not supported.

Not surprisingly, comments from someone with a handle like "die agp die".

Always the optimist. Who's to say some PCIe 2.0 with reduced voltage won't
be introduced in a year's time? Intel, AMD and nVidia have to find new ways
to find "continuous revenue streams".

Thanks to all for filling me in. I still have the original docos that
came with the mobo, but never thought to go to the Intel website. Duh!
And I guess I didn't understand how the AGP specs were named. Sorry.
But at least I can now go look for a card and hopefully end up with
the right one.

many thanks to all...

FWIW I have an Intel 850emv mobo with 2x/4x agp and am successfully
using an x850 4x/8x in it. Also, I found the info and board diagrams
here rather interesting:
