Need help with understanding this bios Error

[Krack1e]

I recently bought a used dell workstation to use as a Plex server and I got this message when trying to boot to Ubuntu on a usb.
I have no idea what any of this means.
Would any of you be able to help?
specs are:
cpu- 2x Xeon e5 2630 v3.
gpu- gtx 1050ti.
ssd- Intel s3500 600gb.
hdd- 2x wd reds.
used tower- Dell Precision T7810 Workstation.
ram- 2x 8gb Samsung m393a1g40db0-cpb

Thanks in advance!

EDIT:
It was a dead cpu.
thanks to everyone who helped me solve it!

Socket 1 APIC 10 Microcode43.

Something in the microcode doesn't like the Kernal.

It's apparently trying to use something that said NO.

Try to disable C-states from the GRUB boot loader (add: intel_idle.max_cstate=0 processor.max_cstate=1), test the memory, CPU and motherboard.

I thought that the motherboard would automatically set to the ram to 1866mhz

It should default to the slower speed.
Try removing the secondary CPU and booting.

I ran the dell bios diagnostics and it freezes on CPU 0

It should default to the slower speed.

Which slot is the second one? Left or right?

Socket one is the one closest towards the front of the tower.
