45nm& Vdroop/load vcore questions

post #1 of 7
Thread Starter 
alright well since the 45nm chips have the voltage limit I am needing some help on what would be considered the safe way to look at this


As it stands my attempt at getting 4.4ghz stable has pushed my volts very far.

1.320 Vcore is the voltage Under Load

1.360 is the Vcore At idle, zero load

Should I be weary of the idle voltage frying the chip, or the LOAD voltage frying my chip?

As it stands, I assume load voltages is what matters since that is what heats and burns up CPU's....however I am uncertain and do not want to burn out my golden chip (4.4ghz is almost 100% stable on 1.32Vcore... only 1 of 4 of my stress programs is failing)

What do you guys KNOW?

My understanding was that it would be under load.

Really why push so high if your just testing to water fine but 4.4 at 24/7 is insane.A 4.0 is just about everyones top o/c its just to hard on your system,imo

From what I have read, the degradation isn't from the heat generated by the voltage:

What I read on the first page was that the voltage burns the chip after 1.4V~

it may be, I was under the impression that it wasn't from the heat though but from electromigration:

Alright that about set my mind

its IDLE volts that count since it also increases current, on top of others who have had degradation... some have not.

Not risking it.

Thanks guys
