@4.6/1.2v is a bad chip if it crash.
Seems in line. Wish mine is a good one, still shipping GOGO UPS GO FASTER!
That is what I have been seeing everywhere to. I have seen that you should not exceed 1.26 on air or a closed loop.
"Due to lithography, integration of the iVR and variable voltage when using adaptive VID for
overclocking, Haswell CPUs require high performance cooling. Dual fan high performance
heatsinks or closed loop radiator water coolers are required for overclocks reaching up to
Overclocks over 4.6GHz will need a solution that can dissipate a much higher level of heat. As
these frequencies will in many situations requires VID in excess of 1.275V. For the majority of
standard air cooling solutions as well as closed loop cooling solutions (single fan and radiator)
your voltage limit will be approximately 1.25 to a maximum of 1.265 volts. With these voltages
expect peak temperatures of approx 90 to 95c+ (regardless of CPU frequency). Keep in mind
these are peak temperatures and not averages. Real world usage will create significantly lower
temperatures that can be managed effectively; up to 1.300 to 1.325 volts. Max temperature
considerations are generally of most concern when synthetic stress test applications or
workloads are used (Prime 95, LinX, OCCT, and Intel Burn Test)."
