How much higher can I raise vcore without damage - Page 2

post #11 of 15
hummm ok, sounds good from what i can see, does your nb get very hot at all, i noticed mine would get unstable but i narrowed it down to when my room gets warm and hence my nb temp starts going up, not sure if this could be the case with yours
other then that im all out of ideas for now, sorry

it must be at 1.55 right now for the nb. speed fan rates it at 35*C at 1.65 it goes up to 38*C I believe

Not 100% correct. Voltage causes damage from just itself....the heat it creates exacerbates the damage. A CPU at 40c and 1.6v will be heavily damaged compared to a CPU at 40c and 1.3v.

You can reduce the damage from high voltage with extreme low temps such as phase change offer, but outside of that........

To properly answer your question about too much damage one would have to know what your expectations for the system are. With those temps at that voltage you're probably ok as long as you don't expect the CPU to function more than 18 months or so. Which is not a guarantee of that length of time, but it's a good chance. If you want it to last longer, you will want to reduce the voltages down to the 1.4 range at least.

Seriously? 1.4 for more than 18 months?
Brrrrrrrr...

For the health of this forum, please keep posts to factual information or data, or state it as an opinion.

Things I know :
1) Damage is NOT solely dependent on temperature; see “Quantum Tunneling†(The_Manual)

2) At a TDP of 65w (all but X6800), Intel recommends a maximum temperature of 60.1C.

3) Intel recommends an “absolute maximum†core voltage of 1.55V with respect to VSS.

What I think is the case :
1) Due to quantum tunneling, as an absolute, voltage damages any silicon structure it flows through.

3) These recommendations are not always applicable to our community. I suppose these values given satisfy a much longer processor life than what most of us would settle for given the potential performance gain.

I do not know :
1) What the curve of the projected lifespan versus voltage looks like. I would expect it to not be linear, probably a log function.
