Chia plotting error

I set up a few days ago my old computer with some upgrde and tried to use for create chia plots.
Specs: Intel I3 3220 3.3ghz and have 2x 4gb of ram. My motherboard doesn’t have multiple x16 slots so i use pcie riser to connect m2 ssd with nvme adapter xD. And its all work fine with storage until i start to create plot. I’m use only one plot at the time due to my hardvare capabilityes but getting constant errors and didn’t manage create plot. Theoretically should work fine and i can’t see the problem.
