DV5 AMD Undervolt

I purchased my DV5 in early Sept of this year. I have wanted to undervolt it, but the problem is the regular undervolt apps did not work. Either I had problems under Vista 64 or the processor simply was not supported, yet.

I stumbled upon an app called PumaStateCtrlDlg after looking over a thread over at tabletpcreview which was able to undervolt the DV5-1008CA. The app is pretty straight forward; just modify the VID’s of each p-state located in a config file and run it.

Results: - The 1008CA has the QL-60

Voltages:
I was able to set p-state 0 to VID 50 = 0.925V @ 1900MHZ
I was able to set p-state 1 to VID 64 = 0.75V @ 950MHZ
I was able to set p-state 2 to VID 64 = 0.75V @ 950MHZ

Anything above a VID of 64 did not yield any difference in voltage
Also, I was able to up p-state 0 to 51 without freezing but it ended up failing Orthos test so I backed it down.

Temperatures:
I only tested stock and modified p-state 0 for temperatures. Each test was performed by doing a cold start and running Orthos for 10 minutes on a flat glass table. In between each test the laptop was allowed to cool down to below 60 degrees Celsius.

Stock – p-state 0 = 1.100V Temp MAX after 10 min = 82 degrees Celsius

Modified – p-state 0 = 0.925 V Temp MAX after 10 min = 70 degrees Celsius


That’s a 12 degree different over 0.175 V, can’t complain with that. In the coming days I plan to test for any increase in battery life with BatteryMon and Orthos.

The pictures below show the apps for testing and monitoring.

Please comment on your results if you have any.

 

Looks Good!

My ZM-86 didn't yield a good enough stable undervolt for me to keep it undervolted. I will try once again after I get the system back from service.

 

Thanks miner, I am just wondering did any of the regular undervolt apps work for you. I had zero success with them until I found the above mentioned?

Also, I ended up running the battery test yesterday. I used BatteryMon to monitor from 100% to 0% or when the laptop abruptly turned off. I ran Orthos during the whole time and at p-state 0.

Stock I ended up getting 53:03 minutes
Undervolted I ended up with 67:23 minutes
A difference of 14:20 minutes

Of course these conditions are not ideal, but it does ensure that each state was tested under the same conditions and it does show that the undervolt is easier on the battery.

 

Hi Compax2405.
I have a ql-60 too. I managed to get to 0,8 and 0,95 volts at minimum and maximum state.
In which voltage are your processor now? Did you managed to get even lower voltages? Have you found some app that works? I looked at rmclock and crystalcpuid. While the 1st is standing still, the last has often updates. Maybe soon we would be able to lower the voltages in all p-states like in the old rmclock.
Best regards.

 

rowboat71, right now I am running 0.75V at 950MHz and 0.925V at 1900MHz, both of these values are stable on my laptop. I would like to try lower voltages on the 950MHz state, but the PumaStateCtrlDlg app only goes to VID 64 = 0.75V maybe this is a limitation of the CPU, I am not sure.

I too have not found any other app that can successfully undervolt the QL-60. Every couple of days I check a few forums that are dealing with undervolt support for the puma platform. RMClock I think may be a long stretch to get support for, but also have hope that in the future that CrystalCPUID will provide support for the QL-60. If anything is found I will update my post with what I have found.

 

I managed to get 0,75v at 950mhz and only 0,95v at 1900Mhz.I also think is strange after i watched the amd power monitor that only the minimum and maximum multiplier is used by the OS.
I think you have a hd3200 too right?I think there's no way to see the temperature of it.I want to see too if the IGP decrease the frequency and voltage by itself, but with my everest and gpu-z i cant see. Everest shows that HD 3200 clock is 500 Mhz, i wonder where it goes down (state 3 for example). I also notice the memory clock (787MHz) when i have 3gb ram 800 mhz, thought it will be lower.I don't know why it is overclocked..

Do you have powerplay tab on your control center?I think this is built on bios. With the cpu undervolted the battery on power saving scheme lasts for about 2.30. Still a shame cause my old athlon tk-57 undervolted with RMclock and with a 90nm IGP alows me to get on the battery for about 2.45 and doesn't pass the 52 degrees..
Have u find another way to lower the temps and get longer battery life?
I'm thinkind about updating my bios - Toshiba A300D-14D(cause it came with 1.9 version and is available now the 2.6)
Thanks for the sharing
Any news i will post here too
