When you installing AGP card, please make sure the following notice
is fully understood and practiced. If your AGP card has "AGP 4X/8X
(1.5V) notch" (show below), please make sure your AGP card is AGP
4X/8X(1.5V).
AGP 4X/8X notch
Caution: AGP 2X card is not supported by SiS
®
648FX. You might
experience system unable to boot up normally. Please insert an AGP
4X/8X card.
Example 1: Diamond Vipper V770 golden finger is compatible with 2X/4X
mode AGP slot. It can be switched between AGP 2X(3.3V) or 4X(1.5V)
mode by adjusting the jumper. The factory default for this card is 2X(3.3V).
The GA-8S648FXM (or any AGP 4X/8X only) motherboards might not func-
tion properly, if you install this card without switching the jumper to
4X(1.5) mode in it.
Example 2: Some ATi Rage 128 Pro graphics cards made by "Power Color",
the graphics card manufacturer & some SiS 305 cards, their golden finger
is compatible with 2X(3.3V)/4X(1.5V) mode AGP slot, but they support
2X(3.3V) only. The GA-8S648FXM (or any AGP 4X/8X only) motherboards
might not function properly, If you install this card in it.
Note : Although Gigabyte's AG32S(G) graphics card is based on ATi Rage
128 Pro chip, the design of AG32S(G) is compliance with AGP 4X(1.5V)
specification. Therefore, AG32S(G) will work fine with SiS
648FX based
®
motherboards.
