Topic: Using cpu + gpu to mine (Read 1183 times)
don't mine with your cpu, it will take forever to get 0,00001 bitcoin, don't lose your time with cpu mining
The strange thing is, that when I've put generate to true - my hashrate for the gpu doesn't seem affected.
I had the cpus going at around 5Mh/s and the gpu didn't change from ~22Mh/s - does this suggest something else might be wrong?

I did this last night and the GPU also didn't seem affected. The CPU threads run in ultra low priority so that shouldn't be an issue I think....
Using the CPU is currently a pointless pursuit. Due to the amount of power from a graphics card, even the most expensive highest performing CPU can only attain a fraction of the speed of a low end GPU. Your better of leaving the CPU to do the job of running the OS.
If you have spare electricity generated, wouldnt you make more money selling that back to the grid rather than using CPU mining?
You can do both. just leave one core available. If you have a quad core with hyperthreading then use 7 cores.
Is there really a difference in mhash/s if you use 7 or 4 cores on an quad core with hyperthreading?

Don't use cpu and gpu mining at the same time. Your cpu will under such a load, your graphics hashrate will drop to the single digits.
Electricity isn't an issue - solar power 
Don't use the CPU. It's just so inefficiency that it costs more in electricity then you get in BTC.
Hi,
I've just set up a gpu miner using poclbm. However, when I run python poclbm.py the only device it picks up is my graphics card. I would also like to contribute my cpu to the workload too.
I notice that in the bitcoin daemon I can set generate to "true". With it false, bitcoind getinfo shows "hashespersec" of zero, but it gets a value when true. I should also mention that when poclbm is running, I am seeing a hashrate of ~22Mh/s from poclbm which seems about right for the card I'm using.. its an Nvidia GT260 (I think - don't actually trust the drivers!).
So my questions are:
Firstly, with the generate set to false, is my gpu miner via poclbm actually working - should I see a non-zero value in hashespersec?
If I set generate to true, with poclbm running, do I get any benefit from the cpu, or should I be running a seperate cpu miner via RPC?
Should poclbm be picking up my cpu as well? - its a Xeon Q9550.
Finally, would I see any benefit from using cuba rather than opencl?
Thanks for any advice
