[SOLVED] WHEA_UNCORRECTABLE_ERROR

Solved thread here - [SOLVED] BsoD while playing games

What the issue was - BUSL0_SRC_ERR_M_NOTIMEOUT_ERR (Proc 1 Bank 0) showing consistently through the DMP files. Implies that the processor sent out a request to L0 cache and there was a delay in return (invalid data, miss, etc). Temperatures were not a problem, BIOS was not the problem, etc... so ultimately the CPU was to be replaced.
