You should be getting closer to 15 Mhps with a PhenomII x6 (if using all 6 cores).
https://en.bitcoin.it/wiki/Mining_hardware_comparison#AMDThat being said even 15 Mhps is worthless.
CPU mining is dead.
GPU mining with NVIDIA GPUs is dead.
Hell GPU mining will likely be dead all together in 6-12 months (FPGA/ASICs).
I know you won't listen (no new miner does) but don't waste your time trying to mine with that hardware.
How can i configure it to get 15 Mhps?
I don't wanna make money with this crap Hardware.
I just wanna learn something about bitcoin mining.
I have enough money to invest for a mining PC (10k-20k Euro)
But i think it doesnt make sense to invest money if i don't even know hoe to mine efficiently.
You know what i mean?
Other question: Do you think it's a good idea to invest money in a mining PC? Does it pays off at the end?
