Title: GPU and CPU mining at the same time? Post by: favelle75 on April 25, 2013, 03:08:04 AM Or is it just a waste of energy to get the CPU to mine (i5-2500K)?

I have a fairly powerful CPU and I was only able to squeeze 4-5 megahash/second out of it, which is pretty pathetic. Title: Re: GPU and CPU mining at the same time? Post by: favelle75 on April 25, 2013, 03:28:55 AM I have a Radeon 7970, but it only gets me 580Mh/s...pretty bad by 7970 standards.

Title: Re: GPU and CPU mining at the same time? Post by: 5120-01-518-6126 on April 25, 2013, 04:18:23 AM Just getting started -- my test rig is dual Xeon 5780's (24 cores) at 3.33GHz and two overclocked GTX480's.
Simultaneous mining BTC on the GPUs at 122 Mh/s and LTC on the CPUs at ~200 Kh/s. Haven't tested LTC mining on GPU's yet. Title: Re: GPU and CPU mining at the same time?

Shortening the lifespan of your CPU is not really worth the benefits of those 4-5Mhs. I also have a i5-2500k and would never think of using it for mining, but not just for this reason. If you attempt to mine with both, using only 3 cores of the CPU as to not affect your GPU mining ability, then if for some reason you end up using the CPU heavily, the GPU will bog down and you will lose GPU hashing ability. Usually by about 75%. So if you end up trying to use both and say, have Windows Defender on autoscan at 3am, you'll end up running a slow scan and lose GPU for hours and hours. Try it out. I learned the hard way. And I'll never do that again.. :( Title: Re: GPU and CPU mining at the same time? Post by: favelle75 on April 26, 2013, 12:47:32 AM Thanks for the tips guys, much appreciated!
