NOTE:
Double width GPUs are supported only on riser configuration 4, and single width GPUs are supported only on riser
configuration 6.
NOTE:
Ensure that x16 cards are installed only in x16 slots. Depending on the riser configuration slots 2, 7, or 8 may not be
available.
NOTE:
Only half length PCIe cards are supported on riser 2 when NVDIMM-Ns with NVDIMM-N battery are installed on the air
shroud.
NOTE:
For configurations that support GPU, maximum four single-wide and two double-wide GPUs are supported when
NVDIMM-Ns with NVDIMM-N battery are installed. Since NVDIMM-N battery is installed on the GPU shroud, GPUs are not
supported on riser 2.
