Hello,   For the errors that appeared, could you do a NVRAM clear and check that in the BIOS if in the power management, system profile is set to "performance optimized". 
Hi there,   I have a R320 (fully up to date) with 3x32GB quad rank mem, which chrashes as soon as ESXi reached vmx_ahci. If I remove a DIMM, or exchange it for 6x8GB, it's fine. What is causing the machine to crash with 96GB?
R320 crashes with 3x32GB ESXi at vmx_ahci
