Table 4. 8335-GCA memory configuration as a function of the number of DIMMs and risers (continued). You read
this table by selecting the individual DIMM size row in the leftmost column, then move to the right and select the
columns for the memory capacity. The riser quantity value that is listed is the quantity of the memory feature code
that can be ordered, which corresponds to the DIMM size in the leftmost column.

Default configurations for the listed memory capacity
2.
Field upgrade for the 64 GB configuration
The memory risers must be installed in the sequence: (1), then (2), then (3), as shown in Figure 34. By
default, the first positions (1) are always populated.
Installing PCIe adapters in the 8335-GCA or 8335-GTA
Learn how to install Peripheral Component Interconnect (PCI) Express (PCIe) adapters in the IBM Power
System S822LC (8335-GCA and 8335-GTA) system.
The 8335-GCA system has three open PCIe slots on the system board. The 8335-GTA system has those
slots as well as two open slots in the PCIe risers.
You can install half-height, half-length (HHLH) PCIe adapters in the system board. You can install
full-height, full-length (FHFL) PCIe adapters in a PCIe riser. The PCIe riser also supports double-wide
PCIe adapters. One of the system board PCIe slots supports double-wide PCIe adapters.
If you need to change the tailstock of the PCIe adapter from one size to another, so that the adapter fits
properly in the socket, see Removing and replacing the tailstock on a PCIe adapter.
