Question for T61/T400 users who undervolted.

Should I enable IDA?

I also notice since I undervolted that my fan is running a lot. Is this normal or am I just being picky?

My temperature while browsing the internet, listening to music is 28 celcious. Is this good?

 

Just read the undervolting guide, heck the first post in the guide should be enough to answer your questions

 

Do you undervolt? Have you ever undervolted? If no, why not?

 

It wasn't worth the hassle for me.

I already have a low voltage processor (SL9400 w/ 17w TDP), it runs very cool/quiet, I get good battery life, and I don't want any more apps running in the tray.

 

I ended up undervolting with RMCLOCK and I did not end up liking it. I uninstalled it and removed the registry edits. Is everything back to normal like I got my CPU?

 

I do, it dropped idle temps a little, helps a bit more when stressing it thru gaming and such

 

Care to share what voltages you got down to for each multiplier? Thanks

 

28 degrees C is a very good temperature (provided you're not sitting outside in Russian winter ). My computer's CPU is idling at 42 degrees right now at room temperature, and it's undervolted.

 

IDA basically kills one core and lets the other core run at a slightly overclocked speed (by about 100mhz to 200mhz).

I have not found it useful and all and leave it disabled. Might be useful on older software or a system running win98 (or some other program or OS that isnt SMP/dual core friendly)

 

Are you going to undervolt your new T500?

 

I don't remember exactly off the top of my head (not at my computer atm). But I think I changed the top 2 multipliers, and the rest are all at the minimum. I think top multiplier might be 1.025V, I'll check when I get home. All chips will have different thresholds for undervolting though, mine I think was kinda average.

 

.9625v @ the 12x multiplier, .9250 (lowest) for all others.

 

Any other opinions? What are your IDLE Temps guys?

 

all multipliers on mine are enabled.
