View Full Version : [ubuntu] Undervolting CPU AMD Turion 64 ML-34 - Ubuntu 10.10

December 1st, 2010, 11:28 AM
Hi! I own an Acer 5024 laptop with AMD Turion 64 ML-34 CPU, with Ubuntu Maverick 10.10. This laptop model has a well documented problem with CPU voltages: if the CPU is under heavy load its temperature exceeds the upper bound, and the motherboard automatically lowers CPU frequence to avoid crash, causing performance drop. There are many workarounds: under Windows XP I definitely solved the problem using RightMark CPU Clock Utility (RMClock)to lower the voltage at each CPU frequence (1.8 , 1.06 and 0.8 Ghz).
Now I'm looking for a similar software under Ubuntu Maverick.
Surfing the net, I read that it's necessary to use a PHC kernel because cpu-freq modules are built in Lucid/Maverick kernels.
Do you confirm that there's no software alternative like RMClock?
Thank you for your help
