PCIe slots
The PCIe slots on Precision 5820 have a different functionality depending on the processor installed. Core i7-78xx has a limit of 28 lanes.
This results in a reduced PCIe lane count to the slots 1 and 4 as shown in the following table:
•
Slot 1 is closest to CPU/memory complex.

Slot 3
Slot 4
Slot 5
Slot 6
NOTE:
All slots are Gen3(8GTs) from processor root hub unless otherwise indicated xX indicates the number of lanes that are
connected to the slot. FH=Full Height, FL=Full Length, DW=Double Wide as defined by PCIe CEM spec *Slots are 300 W
capable. Limited to 250 W per slot when more than one MEGA is installed.
