Installing or Replacing Server Components
To work around this problem, rebalance the load on each IOH using the following methods:
1. Adjust the IOH IO Resource Allocation ratio. This option is included in the BIOS Setup Utility
Advanced PCI Configuration page (see
Figure 3-28).
2. Physically remove any unused PCIe cards.
3. Physically rearrange the PCIe cards to create a balance between IOH0 and IOH1.
In this server, the PCIe slots are connected to IOH0 and IOH1 as follows:
– Slot 1: IOH 0
– Slot 2: IOH 0
– Slot 3: IOH 0
– Slot 4: IOH 0
– Slot 5: IOH 1
– Slot 6: IOH 1
– Slot 7: IOH 1
– Slot 8: IOH 0
– Slot 9: IOH 1
– Slot 10: IOH 1
