Other Notes and Restrictions
•
For the memory modules to work properly, please install DIMM modules in pairs
(with even number of DIMMs installed).
•
All channels in a system will run at the fastest common frequency.
•
Due to memory allocation to system devices, the amount of memory that
remains available for operational use will be reduced when 4 GB of RAM is
used. The reduction in memory availability is disproportional. See the following
table for details.
5-6 Adding PCI Expansion Cards
PCI Expansion Slots
One riser card is used to support PCI expansion cards in the system. The riser
card can support one UIO card and three full-height, full-length PCI-Express x8
expansion cards.
Installing a PCI Add-on Card
1. Remove the chassis cover.
2. Release the locking tab that corresponds to the PCI slot shield for the slot
you wish to populate.
3. Insert the expansion card into the riser card, pushing down with your thumbs
evenly on both sides of the card.
4. Slide the add-on card into the riser card and attach the add-on card bracket
in place of the PCI slot shield.
5. Secure the add-on card by closing the PCI slot shield lever.
6. Connect cables to the add-on card as necessary.
Note: If the left side riser is with 2 or more x8 PCI-E slots make sure an installed
card on the left side riser is detected. If it is not, then go to the system’s BIOS
Setup and in Advanced/ PCI/PnP Confi guration /SXB1 Confi guration BIOS setting
select the [2x8] option. Then save the BIOS setting changes and reboot the system.
