As far as I can tell the BSOD code is of no use in narrowing it. Maybe MACHINE is more likely to be system agent or IMC related and WHEA is more likely to be uncore related, but maybe not. My g3258 has never given me any bsod other than WHEA.
Darkwizzie's recommended method is to change settings and time how long it takes to crash for ~5 tries and based on that you can guess which setting is helpful. Pretty absurdly time consuming.
Yeah fair point. The three oc-related bsod's seem to be interchangeable on haswell. I guess I was just being pedantic.
