Pumastatectrl with ZM-86 / TX2500 ( TX2513CL )

I have been trying to teak Pumastatectrl for my ZM-86 CPU without much luck

Could anyone share their settings ?

My primary goal is to cut the fan noise during regular computing

thanks in advance

 

It doesnt seem to help much. The only way I have found to cut down the fan noise is to create a seperate power plan and setting the cpu to run at 50% clock speed and/or setting the GPU to power saver mode as well. This will get the regular computing fan noise to a minimum. Just undervolting the cpu doesnt do much. In any case, try out your own setting since each cpu even if they are same model is going to have different undervolting abilities. In any case here are my voltages...
2.4GHz = 1.063V
1.2GHz = 0.875V
0.6GHz = 0.750V

 

Agree with miner, best way is to cut cpu at half speed, since it requires really low power when working around 1.1-1.2 Ghz.
My zm-80 has these settings:

[email protected] (default 1.100)
[email protected] (defualt 0.950)
[email protected] (default 0.800)

as you can see, 1.05Ghz runs very well at 0.775 volts.
According to AMD datasheets, my ZM-80 has 15.3W TDP at 1.05Ghz, and becomes 11.3W with 0.775v (saving approximately 4W, as demonstrated also here: http://amd.goexchange.de/)

You may also try my software for downvolt/downclock available here: http://amdath800.dyndns.org/amd/tpc.rar

 

Thanks to both of you for the input.

I will try Turion Power saver today and report my success

I was also wondering if upgrading the CPU from 2.0GHz to 2.4Ghz (or more) is do-able and will that increase heat or consumption ?

Did anyone tried replacing the thermal grease with something more conductive like OCZ Freeze of Artic Silver 5 ?

 

As far as the processor is not soldered onto the motherboard (I don't it is), you should be able to upgrade with a processor of the same family.
Actually there may be some restriction BTW, since higher frequencies mean higher power consumption and more heat to dissipate. We can't be sure if your model fansink is able to deal with some more heat.

For example, on my notebook, a hp dv5-1025el with zm-80, I was able to reach 97°C during heavy stress test. I can't imagine what can happen with a zm-86...!

Of course better thermal grease helps, sometimes it can help squeezing out 5-6 °C, but IMHO hp can offer better heatspreader/fan designs, expecially on latest products.

 

there is also this tool that can also downclock and undervolt
