NHC for Core Duo notebooks?

Well, when I gave NHC a whirl i repeatedly crashed. soo guess not?

 

Which version of NHC were you using? Supposedly the newest beta is compatible, but I don't have any first-hand experience.

 

heh. I could of told you that Tay. Made my Acer 8204 crash. It works as soon as you install it but when you reboot it just crashes

 

Interesting. I wonder if other users are expiriencing this. I don't have a duo so I can't verify this. It would be something to look into.

Beta 03:

@CoolHotCold - did you use beta that's available now?

I setup the last beta but Dynamic Switching doesn't work. In fact, nothing works, the multiplier is kept to the minimum all the time regardless of the setting, hence NHC is useless at this point for Centrino Duo.

Later edit: RMClock however works like a dream.

 

With RMClock only limited to going down to .950V (assuming that default) wouldn't that make it the same as just leaving the processor to Speedstep itself?

 

crashes on the v6j and z62f as well. It should not be used. I am guessing the maker will eventually make a revision.

 

Eddie, beta 3 works ok on my V6J. Guess its a hit & miss ><;

 

I am using RMclock on my new Core Duo Samsung X60. The voltage at minimum CPU speed is fixed at 0.95V, so no extension to battery life under light use (I suspect Intel wants us to buy the LV CPUs if we want more running time). However, I have dropped the voltage at maximum CPU speed from 1.263V to 1.05V, which significantly drops the power used and heat generated under heavy load.

NHC is also limited to .950, unless there are some options that I couldn't find.

Later Edit: My experience as it stands now

Saturday 8 April 2006

Notebook type: V6J-8002P

NHC 1.10beta3:
Does not work. Multiplier freezes at 6x and is never changed by the software regardless of the setting.

RMClock 2.05:
Works fine. Decreased 11x VID from 1.263V to 1.112V.
6x VID cannot be decreased below 0.950V.

MobileMeter 0.310:
CPU Temp, HD Temp, Batt readings work fine
CPU Speed does not detect underclocked CPU.

SpeedFan 4.28:
Does not detect fans (even with Everest installed).
Not a lacking BIOS feature, as Asus NBProbe detects fan speed fine.

 

hmmm interesting, is there a way to unlock or hack rmclock or the bios, in order to undervolt the cpu at the lowest volatage?

I have read a little about undervolting Yonah's at lowest speed, and they all said the same thing, It is locked and you can't undervolt it, except for higher cpu speed.

How about 1000mhz? can you undervolt there?, or any cpu speeds in between, hopefully you can, and its voltage can go lower than .950 and it will increase your batterylife while increase your CPU speed to 1000mhz or somthing.

Or is this not possible?

Thanks,

So for Core Duo - is RMclock looking superior? What is the benefit of undervolting at max CPU usage? Besides saving battery life (i guess) if you are running it on full steam while on battery?


So in layman terms - what is this about Yonah being locked to .95v? Does it mean that no extra battery life will be gleaned from any different programs?

 

I don't think I'm going to mess with my notebook at that level.

At 7x - 11x multiplier, you can undervolt down to .950V. Of course it doesn't make sense for the voltage to go lower than the minimum voltage.
6x multiplier is already 1GHz.

Not just max, but between min and max as well. I only mentioned max because RMClock recomputes the voltages in between on its own (on the setting that I use it).
The advantage is that your CPU will generate less heat when running at higher speeds, thus hopefully resulting in a longer life and lower fan speeds and fan noise. On battery, I myself will run it at lowest speed unless I need processing power really bad

And w.r.t Power4Gear, the advantage is of course that you really know what's going on and are able to control it. In Power4Gear, the CPU speed dropdown is available only on the Battery Saving setting, if I remember correctly.

 

Question about RMclock - how do you know which Profile is currently running? Just red for plugged in and green for battery? Because even when I set the profile for Max Performance and Max Battery, it doesn't seem to SAY which profile is in use at the time.

 

RMClock has its own management profiles and the one in use is revealed when you point to the RMClock icon in the system tray. You need to tick the box to override the current Windows power scheme in the RMClock profile properties window. As a side note, I don't recommend touching the advanced CPU settings. I did, and my computer would not shut down properly.

You see the RMClock icon in the tray? It looks like a washer/gear.

Orange = Performance on Demand (Dynamic Switching)
Gray = No profile selected
Green = Max Battery
Red = Max Performance
