Don't bother CPU mining at all. You will never get anything.

You might also not want to GPU mine either, unless you already had the hardware laying around.

An interesting reply, I can understand (from Hardware comparison chart) that CPU mining is phased out at this point of Bitcoin history but there have been a lot of speculation about GPU mining getting less and less profitable in the days to come. Can you shed some light on this error?

For some reason when cpu mining with all cpu threads + gpu mining, your gpu will automaticly lower to 40%~ usage, only way around this is to limit cpu miner to 1 thread less than maximum available ie. 4core/4thread cpu , set your cpuminer to threads 3 etc.

If you then run gpu miner along with cpu miner, you will get full 3 threads mining on cpu and 100% utilisation on gpu.

Unlike others here, I think its totally worth it to also mine with cpus(specially when you get free power) for the extra mhash/s as long as everything runs stable and doesnt overheat.

GPU MINER: search forum for guiminer, it includes the pclbm gpu miner with a nice gui to control.
CPU MINER: included in above guiminer, inside guiminer setup rpcminer-4way for cpumining and in the cpuminer tab add the flag -t 3 (to leave one thread free so gpu wont throttle)

Follow this advice and you will get cpu+gpu mining nicely.

As the saying goes around here, if you liked my answer, dont be shy to donate to my charity link

there is no point of cpu mining as it uses as much energy as your card and is 15 times slower

try to optimize your miner as people in wiki claims that they have 223 Mh/s @ 1050 Mhz

I use pickup truck, works for me. Any other cars sugested?
