Slots 4 and 1 can be filled with a PCIe3 x16 graphics processing unit (GPU) adapter (FC EC49) or a full-height,
full-length adapter in the 8335-GCA. Mixing of a GPU adapter and a full-height, full-length adapter is supported on
this model.

Slots 5 and 3 are x8 slots. The adapter priority for these slots is for the high-performance adapters followed by any
other adapter.
PCIe adapter placement rules
Use this information to select slots for installing PCIe adapters in the 8335-GCA or 8335-GTA system.
Table 7 provides information about the adapters, the slot priorities in the system they are supported on,
and the maximum number of adapters that can be installed in the supported system. The link that
appears in the feature code column provides more technical information specific to the PCIe adapter.
