I don't have AMD, I run two GTX 970's and I have done it before in ccminer without any short term or long term problems. If you only have one GPU it will basically decrease the hashrate pretty significantly in both instances. Basically your GPU can only compute so much data, overloading it with different Algos will slow both algo's your mining down. (this is my experience in ccminer) Now if you have multiple GPU's, in ccminer i set --cuda-devices in conf to run one of my GTX 970's on one ALGO in one instance, then another instance on my other GTX 970 coputing a different ALGO...some algo's will play nice and some don't together. x-11/x-15 works fine no significant differenct in hashrate. decred/vcash works fine together for me and some others. Neoscrypt isn't friendly with running multiple instances with any other algo in my experience. Anyways thats my take on it, not sure about SGminer but I'm pretty positive it would have a similar result, especially if only mining on one GPU.

Hi everyone,

As my title implies, is it feasible, or safe to run more than one instance of sgminer on my r9 280x?  I'm just curious as to whether or not doing this will cause any detrimental effect to my card or my PC?  One thing I was considering was to perhaps use one instance to control the temp and the fan while it mines one algorithm, and then use the second instance to mine a second algorithm, set them both at the same intensity, clock speeds etc, and thus mine two different algos one card?  is this possible, or am I just asking for my card to fry itself early?  the algos I am seeking to mine are x11 and x15.  Input and advice greatly appreciated!
