Mining and plotting on system with display connected to discrete GPU
-
I have read somewhere that people experience problems while plotting on systems that have no integrated GPU, only a discrete GPU on which the display is used with while plotting. Can someone please explain these issues? Will the same issues occur while mining as well?
I'm going to build a system for mining, and need to know whether I should have integrated GPU in addition to discrete GPU.

I encountered it only while ploting with default setting for a GPU, but once i tweaked em for a bit (maybe lost some hash power but still faster than cpu) problems where gone.
Now as for a problems themself i have seen writen that display go black until drivers crash and restart. In my case it was total system freeze to the point i had to restart manualy.

@LithStud May I ask what kind of GPU you were using?
-
@Propagandalf ahh forgot to mention i have R9 270x 2GB model :) so fairly old video card :)

@LithStud k, thx! So, in sum, the issue is probably less of a problem with a better GPU, and can be handled by tuning down the amount of resources dedicated to plotting. Moreover, the problem goes away completely by having another GPU connected to the display.
-
well as i said, you can really get by with one GPU :) i suspect the default devices.txt setings assigns too much GPU RAM (like say 4GB while it only has 2GB) and thus crashed my system.
-
@LithStud That could be it, yes! :)

@LithStud
But, as the system I wish to build is intended for plotting and mining Burst as effectively as possible, I think I will go for an i7 with integrated GPU and also have a discrete GPU.The Xeons look good as regards longevity, multithreading and the way they handle memory (ECC RAM), but they don't have integrated GPU.
