Memtest errors and cpu

[Vikkun]

So after doing the memtest I found these errors on the midway 

Are these errors all related to ram or cpu too as it says cpu 0,1,2,3

I am using one 8gb ram only

My cpu is i5 8400 as you can see in the pic but those l1 ,l2 and l3 cache organisation seems a bit doubtful,are they ok?

You seem to run the test with all 6 cores at once. That usually throws errors even if it can be fine.

Try with one core at a time for longer.
