LDT Bus and Power Consumption

I recently found a tool to increase the LDT bus speed. All multipliers are locked, so memory, HT Link, and CPU speed all increase. If I lock the voltage of the CPU, does operating at a higher speed still consume significantly more power? What about the memory power draw and HT link itself?

Conversely, if I lower the LDT bus speed so that my CPU can run at 400 MHz compared to 1600 MHz, but do not change the CPU voltage, will the battery life increase substantially?

Thanks

 

The power requirements of the HT bus are pretty miniscule compared to the other components of the system. By default the Turion X2 is capable of disconneting(turning off) the bus to save power as and when necessary. The memory also downclocks when the cpu is running at its lowest multiplier. If you want to decrease the power consumption or heat output, then the best thing would be to undervolt the cpu. Just lowering the clock sped without decreasing the voltage wont bring any good benefits. Ofcourse the ability to undervolt depends on luck and how good of an undervolter is the cpu.

 

What about AMD-V? Does enabling that consume more power or offer any performance benefits?

 

If you dont use it, then turn it off. AMD-v is only useful if you use virtualization software like vmware or Virtual PC '07. There wont be any noticable power saving by turning it off.
