ESXi PSOD and random freezes

Hi folks,

I am new with ESXi. And my english is far from good but here is the problem.

I have 3 hosts running ESXi and which i thought has best hardware, consistently freezes from time to time. One once even gone to PSOD.

His hardware are supermicro SYS-6018R-WTR (BIOS version 2.0b) 2 x Xeon E5-2620v4, 64Gb ddr4 ram, LSI 9260-4i RAID with battery, 4 server toshiba disks.

Look at the picture below with error message:

Is it something related to processor?

Thank god we are on holidays until 9th of January but please can somebody enlighten me what can be done to make this host stable?

Thank you!
