After installing an NVIDIA GRID K1 PCIE card into the R2224GZ4GC4 server the units boots with the error code 146, PCIE is out of resources. The NVIDIA card is the only expansion card installed other than the integrated SAS RAID module. The setup menu indicates the RAID module is not installed with the NVIDIA card installed and the PCIE OP ROM configuration disappears.
As the error message states, it seems that the BIOS is unable to allocate enough resources for your cards. We have an article on our website with some recommendations to address this.
