Can a high clock cause dmg? - Page 2

post #11 of 16
The only temperature you need to worry about is distance from tjmax. That is all the on-die DTS can read anyway. It will not list absolute temps, and it's not accurate at idle.

Obviously the further you are from the tjmax, the better, but at near stock speeds and votlages you should beable to go within a few degrees of it with no ill effects. While apply extra voltage, you will want a larger delta.

Anyway, the 1.36v should be safe 24/7.

As for prime, I do 24 hours of small FTTs to target the CPU only, then I do 24 hours of Large FTTs to target the FSB a bit as well. Blend is of dubious use, as it does not stress the CPU as muc as the other tests, and does not stress the memory any where near as much as memory specific tests.

1.38v is said to be the maximum safe point for al current Penryn processors, duo and quad.

Keep an eye on the temps!
There is a thread on here now called Official overclocking tools. Download that package


why 55*C and why shut down at 60*c?

hes just putting you on the safe side cuz if its too hot too long it will cause permanent damage and this will prevent that...

why 55* and 60*c specificly though.why not 60* and 65* or even 65* and 70*c

I tend to agree. From what I have seen from people with 45nm CPU's, they tend to worry more about temp and less about voltage. It should be the other way around. Load temps in the mid to high 60's can be OK as long as voltages are within reason. Also, keep in mind that all temp readings are no accurate anyways. I know it is the only thing we have, but they should all be taken with a grain of salt as to what the number says. As has been stated, the only important thing is delta to TJ max.



As far as the OP, voltage and heat are your enemies. Clock speed increases, while slightly increasing heat (and I mean SLIGHTLY), do not damage the CPU much if at all. Different CPU's are able to run different speeds depending on batch, quality etc. that is why some CPU'd have a lower VID than others. the fact that all CPU's of a given make/model are all sold at a specced speed is for marketing purposes etc.
