Expansion Card; Procedure For Expansion Card Installation - JETWAY 865GDM User Manual

1. Dual channel function only supports when 2 DIMM Modules plug in either both DIMM1 &
DIMM3 or DIMM2 &DIMM4, or four DIMM Modules plug in DIMM1~DIMM4.
2. DIMM1 & DIMM3, or DIMM2 & DIMM4 must be the same type, same size, same frequency
for dual channel function.
Generally, installing DDR SDRAM modules to your motherboard is very easy, you can refer to
figure 2-4 to see what a 184-Pin DDR266/DDR333/DDR400 DDR SDRAM module looks like.
NOTE! When you install DIMM module fully into the DIMM socket the eject tab should be
locked into the DIMM module very firmly and fit into its indention on both sides.
WARNING! For the DDR SDRAM CLOCK is set at 200MHz, use only DDR400-compliant DDR
Modules. When this motherboard operate at 200Mhz, most system will not even
boot if non-compliant modules are used because of the strict timing issues, if your
SDR Modules are not DDR266-compliant, set the DDR SDRAM clock to 133MHz
to ensure system stability.
2-5 Expansion Cards
WARNING! Turn off your power when adding or removing expansion cards or other system
components. Failure to do so may cause severe damage to both your motherboard
and expansion cards.

2-5-1 Procedure For Expansion Card Installation

1. Read the documentation for your expansion card and make any necessary hardware or
software setting for your expansion card such as jumpers.
2. Remove your computer's cover and the bracket plate on the slot you intend to use.
3. Align the card's connectors and press firmly.
4. Secure the card on the slot with the screen you remove above.
5. Replace the computer system's cover.
6. Set up the BIOS if necessary.
7. Install the necessary software driver for your expansion card.
2-5-2 Assigning IRQs For Expansion Card
Some expansion cards need an IRQ to operate. Generally, an IRQ must exclusively assign to
one use. In a standard design, there are 16 IRQs available but most of them are already in use.
DIMM1 & DIMM3: Dual Channel 1
DIMM2 & DIMM4: Dual Channel 2
