R730XD suddenly not working error UEFI0066

Hello,

can you try to remove all PCI cards first and see if the problem is the same?

If without any PCI cards problem disappears, can you try to isolate the PCI card testing it one by one?

Hi, might be helpful to update intel chipset with BIOS. and also you can check bifurcation settings under integrated devices. And set to deafult bifurcation. However I realized below text in page 22 https://dell.to/3oREjHs

GPU support
The R730 supports GPU technology, which can provide accelerated performance for a variety of
applications, including VDI and HPC implementations.
Note: GPU support is limited to compute and co-processing only; external video out is not
supported.
The R730xd does not support internal or external GPUs.
Internal GPU support
The R730 supports two 300W, full-length, double-wide GPUs or up to four 150W, full-length,
single-wide GPUs. Each GPU can support up to 6GB of dedicated GDDR5 memory. Active cooled
GPU cards not supported. The GPUs are installed on the PCIe x16 3.0 interfaces available on riser 2
and GPU-optional riser 3. A system must have the optional riser 3 with a single x16 slot to support
two double-wide GPUs. A standard riser 3 is required to support 3 or 4 single-wide GPUs.
Because GPUs demand high power, each GPU has up to two power connectors for power delivery.
The GPU enablement kit is required for internal GPU installation. The kit contains the power cables
and other items to enable GPU support on the R730 chassis.

Thanks Marco,

I’ve isolated it to my Nvidia A2000 PCIe card. I’ve updated the firmware on the card as well as the BIOS, but the error persists. I have found a way to log in despite the error, but it still gets in the way of server restarts and remote management.
