Dynamic switching using the NHC tool recommended?

[hamoudi]

hi guys...its me again

im using the NHC now on my T42 and id like to ask if the dynamic switching is good or not for the CPU itself?? i thought to myself that switching frequencies that fast and that often must be pretty much damaging for the CPU.

anyone with infos? id be thankfull....

If anything it'd be good for it i imagine. I don't think it'd do any harm, the CPU itself wouldn't get any strain from switching frequencies, and the power regulation systems in a laptop are built for quick switching between voltages anyway, and I imagine keeping them lower 95% of the time as dynamic would would be of benefit to the lifetime of the hardware anyway.

So in short: don't worry about it.

At any regulation level, the Intel chipsets do their own frequency switching; the NHC one is not much different from the adaptive mode in the Power Manager or in Windows. It doesn't harm the CPU at all.

hi guys,
thanks for ur help. but id like to mention that in windows i guess dynamic switching is only between min and max right? correct me if im wrong.
what about having all these 6x,8x,10x....17x steps in a dynamic switch?? is it also good or would u recommend switching between min. and max. only?

id be thankfull for any tips, advices ,new infos u bring in concerning dynamic switching under NHC

PS: using dynamic switching i spared my laptop 7 degrees difference ! its pretty much awesome. so i really need to know more about it.....


thanks

That is perfectly fine, it is a selling and big operating point of the Intel chipset in your Thinkpad; nothing bad can happen if you let the system and the CPU decide what clock to run at.
