Hello,

Is it possible to have a CPU miner and GPU miner active at the same time in the same computer without overloading?  Or is this a risky method to use, prone to crashes etc?

Thanks

Every time a block is mined, a certain amount of BTC (called the subsidy) is created out of thin air and given to the miner. The subsidy halves every four years and will reach 0 in about 130 years.

Totally possible and many people are doing this, just make sure nothing is overheating and that the PSU can handle the load. you'll have some trouble finding a profitable CPU coin.

Many thanks.  Going to do some research on the best graphics cards available, to your knowledge whats the most cost effective with the strongest hash power?

Yep, go with RX 470s. those are the best bang for the buck when it comes to mining.

If you have a good temp in your place it can be possible but i think if you run cpu and gpu in the same time it can hurt your cpu.. so i think i you can build a super pc its more good if you just run even 6 cpu and 1 cpu for your running your pc normally.. and full in gpu..
But if you want to be safe better to build a mining rig only for gpu mining..

Oh I see, I actually have 8 core CPU's... if I mined only with say 5 cores then also mine GPU, would that be safer?

GPUs use to be more problematic on overload, since on high temperature their fan has to work a lot for long time. From what I've read some time ago the fans are the first to break.
CPU is not an issue. And you can start CPU mining with lower priority and the other processes will have their chance to use the CPU if they need it.
On windows that's start /low minerd......

Thanks.  Is a Sapphire "AMD Radeon RX 480 8GB GDDR5 RAM PCI Expess 256 bit" a good choice?

That is a good card for running the Ethereum mining. But it might not be so good for the ZCash mining.

You can use zcash cpuminer with 6 cores heat is by 51-54
And at the same time the zcash gpu miner heat is by also 53-58

Hello,

Is it possible to have a CPU miner and GPU miner active at the same time in the same computer without overloading?  Or is this a risky method to use, prone to crashes etc?

Thanks

All of my rigs with 6, 7 or 4 none reference RX 480 card setup , im using the GPUs to mine ETH , and CPU's to mine XMR.
If im mining with all core , its add 50-70 watts power drawn at the wall with high end cpus like i7-5960x  , or Intel Xeon E5-2666 v3 ES 10C Processor , and 20-25 watts for Intel Core i5-4440S.
Using Claymore CryptoNote CPU Miner v3.5 Beta for XMR
and Claymore's Dual Ethereum+Decred_Siacoin_Lbry AMD+NVIDIA GPU Miner v7.2 for ETH

Same here, GPU and CPU on all of my rigs mining ETH/XMR

Will be switching around to Zcash in a few days on a couple of them.

With proper cooling and good power supplies, not an issue.

I've got a few rigs running AMD A10 78xx series APUs with multiple NVidia GPUs, or with dual NVidia CPUs and an AMD HD7750.

 The most of the CPU cores are working Gridcoin (BOINC / Moo Wrapper / Distributed Net), as does the APU on the AMD A10 (and the HD 7750 if present, Moo Wrapper doesn't need a lot of RAM, and AMD GPUs of ANY size that can do OpenCL at all are VERY good at Moo Wrapper / Distributed Net work).
 The NVidia GPUs are mining something else, depending on which machine and which GPU model is involved.

 At one time I had similar setups (or the same in the case of 2 of the older such rigs), with the CPU cores running the Mersenne Prime (Prime95) program, the GPU on the APU running Distributed.net, and NVidia GPUs doing something else, for *3* seperate activities on one machine. Needless to say I didn't try to do ANYTHING ELSE on those machines as they were very loaded down with the crunching activities.


I'm no longer legendary just in my own mind!

When I try and mine with both a GPU and CPU they badly interfere with each other and I get much slower hash rates Sad  any idea what i'm doing wrong?

What hardware are you using? The CPU seems to be weaker one, in a case like that.

Of course you can ! I used to do it when I was mining ZCoin a week or two ago. Just make the sure the CPU doesn't overheat and you're fine !

You can. But whether you should that's another story. Ask yourself this. Is it a dedicated mining computer or not? Are you going to use the computer for other tasks too?
If the answer is yes, and you decide to use the CPU too, you should definitely fine tune the load of the CPU. With high loads your computer will be useless for anything other than mining.
