Graphics Card not Detected in Intel® Server Board S2600CW Family

What am I seeing?

What are the environment details?

Board with only 1x processor

How to fix it

1. Check if the Add-in video adapter is installed in the correct PCI Express* slot. See details below, which are taken from Table 1 of the Technical Product Specification (TPS):

   From PCH:

   • Slot 1: PCIe Gen II x4

   From the first processor:

   • Slot 5: PCIe* Gen III x16/x8 electrical with x16 physical connector. Electrical x16 for S2600CW2R or S2600CWTR, electrical x8 for S2600CW2SR or S2600CWTSR
   • Slot 6: PCIe Gen III x16 electrical with x16 physical connector

   From the second processor:

   • Slot 2: PCIe Gen III x16 electrical with x16 physical connector
   • Slot 3: PCIe Gen III x8 electrical with x8 physical connector
   • Slot 4: PCIe Gen III x16 electrical with x16 physical connector
2. You need to connect both CPU power connectors for all the PCIe slots to work, even when only one CPU is installed.
3. While PCIe slot 5 is also x16 connector, only 3 x16 PCIe slots on the board can support up to 75W slot power at once. This configuration limitation is based on the System Power budget. When used as a riser slot, slot 6 can provide up to 75W power to the riser.
4. When the Onboard Video BIOS option is disabled and the Add-in Video Adapter option is enabled, only the Add-in video adapter is active. Therefore, make the changes below to the BIOS setup when an Add-in video adapter card is installed (Refer to the TPS for more insight):

   When there is one add-in video card connected to CPU Socket 1
   Case 1: Onboard video active display, add-in video doesn't display.
   Onboard Video = Enabled
   Legacy VGA Socket = CPU Socket 1 (grayed out, can't change)
   Add-in Video Adapter = Disabled

   Case 2: Add-in video active display, onboard video doesn't display.
   Onboard Video = Disabled
   Legacy VGA Socket = CPU Socket 1 (grayed out, can't change)
   Add-in Video Adapter = Enabled

   48 Revision 2.1

   Case 3: Both onboard video and add-in video are active displays. But only onboard could be the active display during BIOS POST (Dual Monitor).
   Onboard Video = Enabled
   Legacy VGA Socket = CPU Socket 1 (grayed out, can't change)
   Add-in Video Adapter = Enabled

   When there is one add-in video card connected to CPU Socket 2
   Case 4: Onboard video active display, add-in doesn't display.
   Onboard Video = Enabled
   Legacy VGA Socket = CPU Socket 1
   Add-in Video Adapter = Disabled (grayed out, can't change)
    
   Case 5: Add-in video active display, onboard video doesn't display.
   Onboard Video = Disabled (grayed out, can't change)
   Legacy VGA Socket = CPU Socket 2
   Add-in Video Adapter = Enabled (grayed out, can't change)

   When there are add-in video cards connected to both CPU Socket 1 and 2
   Case 6: Onboard video active display; add-in video on Socket 1 and Add-in video on
   Socket 2 don’t actively display.
   Onboard Video = Enabled
   Legacy VGA Socket = CPU Socket 1
   Add-in Video Adapter = Disabled

   Case 7: Add-in video on Socket 1 active display; onboard video and Add-in video on
   Socket 2 don’t actively display.
   Onboard Video = Disabled
   Legacy VGA Socket = CPU Socket 1
   Add-in Video Adapter = Enabled

   Case 8: Both onboard video active and CPU Socket 1 add-in video active display. But only onboard could actively display during BIOS POST.
   Onboard Video = Enabled
   Legacy VGA Socket = CPU Socket 1
   Add-in Video Adapter = Enabled

   Case 9: Only CPU Socket 2 add-in video active display, neither onboard video nor
   CPU Socket 1 add-in video actively display.
   Onboard Video = Disabled (grayed out, can't change)
   Legacy VGA Socket = CPU Socket 2
   Add-in Video Adapter = Enabled (grayed out, can't change)

5. Update the firmware of the server motherboard to the latest version.
6. The minimum power supply wattage required for the motherboard is 550W. However, when an add-in video adapter card is installed, a power supply of 750W DC power output is required.
