Hi,
The 4X and 8X denotes the speed of our
agp port
The 1.5 and 3.0 denotes the voltage supplied by the
agp to the
GPU..
So you board support Graphic card with 4X speed and 1.5V voltage specification.
you should visit the manufacturer's website for. (there is generally a
compatibility chart). Major brands such as
Nvidia and
ATI have this. The most simple way to tell if your card is compatible is to look at the
agp slot on the motherboard and the pins on the card. a 1.5v compatible card has a "key" (slot) closest to the rear of the card. A universal card has 2 keys, one near the rear and one near
thr front.
Please refer
ATI website to check the compatibility with your board before buying graphics card
Here is the diagram to show the
differences
Please leave me coments if you need furthur assistance
