Gigabyte GA-7VA User manual

When you installingAGP card, please make sure the following
notice is fully understood and practiced. If yourAGP card has
"AGP 4X/8X(1.5V) notch"(show below), please make sure yourAGP
card isAGP4X/8X(1.5V).
Caution: AGP2X(3.3V) card is not supported by VIA®KT400.You
might experience system unable to boot up normally. Please insert
anAGP4X/8X(1.5V) card
Example 1: Diamond Vipper V770 golden finger is compatible with
2X/4X modeAGP slot. It can be switched betweenAGP2X(3.3V) or 4X
(1.5V) mode by adjusting the jumper. The factory default for this card is
2X(3.3V).
The GA-7VA(or anyAGP 4X 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) modeAGP slot, but
they support 2X(3.3V) only. The GA-7VA(or anyAGP 4X only)
motherboards might not function properly, If you install this
card in it.
Note :Although Gigabyte'sAG32S(G) graphics card is based on
ATi Rage 128 Pro chip, the design ofAG32S(G) is compliance
withAGP 4X(1.5V) specification.Therefore, AG32S (G)will work
fine with VIA®KT400 based motherboards.

DDR Introduction
Established on the existing SDRAM industry infrastructure, DDR (Double Data Rate) memory is a high
performance and cost-effective solution that allows easy adoption for memory vendors, OEMs and
system integrators.
DDR memory is a sensible evolutionary solution for the PC industry that builds on the existing
SDRAM infrastructure, yet makes awesome advances in solving the system performance bottleneck by
doubling the memory bandwidth. DDR SDRAM will offer a superior solution and migration path from
existing SDRAM designs due to its availability, pricing and overall market support. PC2100 DDR memory
(DDR266) doubles the data rate through reading and writing at both the rising and falling edge of the clock,
achieving data bandwidth 2X greater than PC133 when running with the same DRAM clock frequency.
With peak bandwidth of 2.664GB per second, DDR memory enables system OEMs to build high
performance and low latency DRAM subsystems that are suitable for servers, workstations, high-end
PC's and value desktop SMA systems. With a core voltage of only 2.5 volts compared to conventional
SDRAM's 3.3 volts, DDR memory is a compelling solution for small form factor desktops and notebook
applications.
1. The DIMM slot has a notch, so the DIMM
memory module can only fit in one direction.
2. Insert the DIMM memory module vertically into
the DIMM slot. Then push it down.
3. Close the plastic clip at both edges of the DIMM
slots to lock the DIMM module.
Reverse the installation steps when you wish
to remove the DIMM module.
