Gigabyte GA-7VT880 Pro User manual

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.
Caution:AGP 2X card is not supported by VIAKT880. 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
modeAGPslot. It canbeswitchedbetweenAGP2X(3.3V) or4X(1.5V)mode
by adjusting the jumper. The factory default for this card is 2X(3.3V). The
GA-7VT880 Pro / GA-7VT880-L / GA-7VT880 (or anyAGP 4X/8X only)
motherboards might not function properly, if you install this card without
switching the jumper to 4X(1.5V) mode in it.
Example 2: SomeATi 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-7VT880 Pro / GA-7VT880-L / GA-7VT880 (or any
AGP4X/8Xonly)motherboardsmightnotfunctionproperly,Ifyouinstallthis
card in it.
Note :Although Gigabyte'sAG32S(G) graphics card is based onATi Rage
128 Pro chip, the design of AG32S(G) is compliance with AGP 4X(1.5V)
specification. Therefore, AG32S(G) will work fine with VIA KT880 based
motherboards.
Before you install PCI cards, please remove the Dual BIOS label from PCI
slots if there is one.

If you wanttooperatethe DualChannelTechnology,pleasenotethe following explanationsdue
tothe limitation ofVIAchipsetspecifications.
1.Onlyone DDR memorymoduleisinstalled:The DualChannelTechnologycan'toperate
when onlyone DDR memorymoduleisinstalled.
2.TwoDDR memorymodulesareinstalled:The DualChannelTechnologywill operate
