As I've promised, here is tool which will test your processor according to TCase_Max.
This is just early preview version, however everything shoud works okay.
It supports all currently avaiable 4th gen Haswell Desktop i7 (rest will be added after some positive feedback).
This software will calculate TCase_MAX according your CPU TDP and Thermal profile.
During stress test, it will check, if CPU _package_ (not each core) temperature will not cross TCase_Max+10% (this will need some tuning later, I think, but for begining let say 10% tolerance).
it will also display cores requested speed, and current speed.
when cpu is melting, or there is not enough ampers (i7 have no power limiter, but current limiter. so if your vcore is tuned down to let say 1.09, you will get 200-300mhz less, because 1.09*95amps, and 1.16v*95amps gives you diffrent power values.. more power=more speed!)
it will read MSR register and show why power is throttled back (thermal problem, no enough current, power plane limiter, power package limiter, core limiter, etc).
So if anybody can test this SW and let me know about results, would be cool.
