Gigabyte 6VXDC7, GA-6VXDC7 User Manual

FCC Compliance Statement:

This equipment has been tested and found to
comply with limits for a Class B digital device,
pursuant to Part 15 of the FCC rules. These
limits are designed to provide reasonable
protection against harmful interference in
residential installations. This equipment
generates, uses, and can radiate radio
frequency energy, and if not installed and used
in accordance with the instructio ns, may cause
harmful interference to radio communications.
However, there is no g uara nte e that interference
will not occur in a particular installation. If this
equipment does cause interference to radio or

television equipment reception, which can be
determined by tur ning th e equi pment off and on, the us er is e ncourage d to try t o
correct the interference by one or more of the following measures:

-Reorient or relocate the receiving antenna

-Move the equipment away from the receiver

-Plug the equipment into an outlet on a circuit different from that to which
the receiver is connected

-Consult the dealer or an experienced radio/television technician for
additional suggestions

You are cautioned that any change or modifications to the equipment not
expressly approve by the party responsible for compliance could void Your
authority to operate such equipment.

This device complies with Part 15 of the FCC Rules. Operation is subjected to
the following two conditions 1) this device may not cause harmful interference
and 2) this device mu st a cc ept any interference received , in cl uding interference
that may cause undesired operation.

CPU Speed Setup

The system bus speed is selectable at 66,100,133MHz. The user can s elect the system bus
speed

(SW1)

and change the DIP switch

(SW2)

selection to set up the CPU speed for

500MHz – 1GHz and faster processor.

Set System Bus Speed

The CPU speed must m atch with the frequency ratio. It will cause system hanging up if
the frequency ratio is higher than that of CPU.

Intel Processor all have locked Frequency Multiple, so yo u can not change the CPU

Frequency Multiple.

0000

For double CPU use, the same CPU m ust be used in CP U socket1 and 2. (The same

stepping, FSB, ratio)

0000

For single CPU use, use CPU socket1 only. Don’t use CPU socket2.



Note: We don’t recommend you to set up your system speed to 112 , 124 , 142 ,152 MHz

because these frequencies are not the standard specifications for CPU, Chipset and
most of the peripherals. Whether your system can run under 112 ,124 ,142 ,152 MHz
properly will depend on your hardware configurations: CPU, SDRAM, Cards, etc.

normally Line Out, when it output digital signal, it
will be change to SPDIF Out automatically (see

Line In: In general, Line In is normally Line In.
When you select “Four Speaker” in Creative
