what ta hell, sell that, you got a very very very very very very ( and a lot of more very) bad silicon, shit some can oc up to 4ghz with stock voltage. I reccomend you to sell your cpu
what cpu cooler do you have?
I have the same cpu with a dark rock tf and have 4.3 @ 1.136v
what temps do you have? How are you overclocking? 3.6@ 1.35 just sounds wrong. I'm no expert with O/C but something seems amiss.
