Resolution
1
Download and install the GPU-specific drivers from
the card manufacturer website.
2
Ensure that the CMOS token for C410x is set properly.
3
Ensure that the appropriate power sequencing is
followed.
1
Reduce the number of GPU cards or PCIe cards
installed in the system. For more information, see
"Example Configurations With Maximum Number of
GPUs Supported".
NOTE:
The maximum number of PCIe devices supported
depends on the memory resource requirements of each
individual card.
2
Set the C410x port configuration to 2:1 or 4:1 mode.
NOTE:
The C410x does not support the 8:1 mode in the
M610x, R710, and R410 systems due to limited system
resources for PCIe devices.
