AGP on the new motherboards no longer supporting the older 3.3V Video cards?

I just bought and installed an Abit KV7 into my daughters machine.  It has a new divider in the card slot that does not match the older cards. Book says....

"This Motherboard does not support 3.3v AGP cards.Use 1.5 or 0.8v cards only"


My question is Since when?
and Why?

Which video cards are 3.3V?
(other than my old 3dfx voodoo 5500 64 mb)

Granted I have her system up on an old gforce 2 pci card.

The upgrade was from AMD 800 mhz to a AMD Sempron 2200. Abit KV7 Mboard, 256mb of ram. Assembled & tested, it was 132$ package from Mwave.com.

System screams along nicely on stock settings.

There are basically 3 types of AGP cards/slots.

3.3V, 1.5V and Universal.

AGP 1.0 is for 2x cards at 3.3V.  AGP 2.0 is for 4x cards that maintain backwards compatibility to 2x slots, and will run at either 1.5V or 3.3V.  AGP 3.0 (current standard) is for 8x cards that maintain backwards compatibility with 4x slots, and will run at either 0.8V or 1.5V.  To complicate matters (or simplify, depending on your POV) ATI makes some cards in the 9200, 9500 and 9700 series families that are Universal, meaning they can operate at any voltage/speed from 3.3V 2x up to 0.8V 8x.

3.3V slots have the divider in the front, 1.5V have them in the rear, and Universal slots have no dividers.  A MOBO with a Universal slot will support any speed/voltage video card.
