Undervolting a c2duo question

Hi, I am trying to undervolt my Vostro 1500 c2duo 1.6 and i am using NCH 2.0 but under the Voltage tab I have no multiplyers correlating Voltage ?? anyone know why.
Also i have no Temp reading for the Hard Drive it just sits at 0 Degrees?

 

NHC also had issues for me in Vista. I would recommend looking at rmclock instead, at least until NHC gets the kinks worked out.

My only issue with rmclock is that on boot, UAC asks me to approve it. To get aroun that, I used the task scheduler to run it on login, but that threw me into a BSOD loop. I went into safe-mode, activated the Administrator account, restarted, and logged in as Admin. Then I removed rmclock from the task scheduler, and no more BSOD. Very odd, because I can run rmclock just fine if I start it manually or endure the annoyance of the UAC approval. I don't want to turn UAC off, but I am looking for other solutions to this problem.

 

Is Rmclock vista-ready?

 

Rmclock works, for me, in Vista, I don't know if RightMark has certified it as "Vista-ready." NHC also works in Vista for some people, but not for me. I'd just go ahead and try them both.

 

Afaik NHC quite simply does not support the Santa Rosa chipset yet.
So no Vista issue, but you ll have to wait until NHC gets an upgrade.

 

The newest version of rmclock has alot of fixes in it for vista. Check it out!

 

Thank you all, i will try RM clock and see what i can do, just looking to knock a few degrees of when im putting a bit of a load on the CPU,

I have the same issue with NHC and the UAC its a pain but i guess it worth keeping. i hear that disabling it frees up a little boot time and system memory.

Thanks again - James

 

Using RMClock, I actually have a reduction 12 degrees Celsius, at least according to the monitors on RMClock itself. I haven't confirmed that yet using any other programs. Just make sure you stress test your CPU after undervolting, I used a program called Orthos. Very simple to use, helped me a lot to determine what voltages to use.

 

If i Over undervolt it and it fails a stress test there isnt any chance i could damage my cpu is there?

 

Not that I know of, no. Orthos will also stop the test once it detects an error, then you can go in, adjust your voltages, and retest. I haven't heard any reports of any CPUs being damaged by undervolting.

 

If you push the volts too low then either you will either start to see errors or the computer will crash and reboot. So do your undervolting trials with nothing critical running.

My method is to be running two instances of the Prime95 torture test (one for each core) drop the maximum voltage to 1.10V then gradually step down from there with a minute or two at each voltage step until something crashes or Prime95 reports an error. You may well find that the CPU still runs at full speed at the lowest voltage you can use.

Once you know the crash voltage then go back up two steps and leave the torture tests running overnight. If that is OK then you are pretty safe to keep that as the permanent setting. I use RMClock's auto-infill for the intermediate steps.

Ah, thanks,

Do any of you that use RMclock notice any draw backs, i hear this and that about c4 and rm clock takes a lot of power to run, and it also takes controll over some other computer processes, If so im not so sure i want it. I just want to be able to undervolt my cpu to lose some degrees, but i dont want all the other crap that it comes with, is this possible?

thanks again.

 

RMClock takes less resources than NHC does , so performance would technically increase compared to NHC. The other processes you're talking about I would assume would be the power schemes. RMClock allows independent schemes, ie you can choose either the windows scheme or create a custom one to override windows. You can do this for both battery and AC.

 

Orthos is essentially Prime95 but tasks both cores simultaneously for you.
