GPU falling off bus

Hello I am having some troubles with my computer, my configuration is as follows:

4x 4090
2x epyc 7742
rome2d32gm-2t motherboard
512 samsung ecc ram @3200 mhz
2x 1600w evga super nova psu
1x 2000w evga super nova psu
4x c-Payne slimsas adapters

Each of the 1600w psu’s have 2 4090’s on them
the 2000w is just powering the motherboard and cpus

Im on nvidia-driver 525

I keep getting this error:
bad nvidia_smi: {‘ERROR’: ‘Unable to determine the device handle for GPU0000:01:00.0: Unknown Error\n’}

I am able to consistently get this error when I run the this bench mark

If there’s any information I left off please let me know and I’ll be happy to include it.
