Error : BUSL0_SRC_ERR_M_NOTIMEOUT_ERR (Proc 0 Bank 0) Status : 0xf200084000000800
The above bolded error (BUSL0_SRC_ERR_M_NOTIMEOUT_ERR) means the processor sent out a read request to L0 cache and there was a delay in return (either a cache miss, or invalid data in cache). So I was definitely right about it being cpu related.
Do you have both 4-pin cpu power connectors plugged into the motherboard? If only using one please plug in the other and retest the system.
