I would very much appreciate peoples assistance.
I'm having problems with the black screen crash whist running QTMiner for Ethereum.
I'd been running an MSI R9 290x on windows 7 64 bit with amd 14.12 drivers and installed open cl.
I added a second GPU (MSI R9 390) and initially the rig ran at 55-58M/hs which i was pleased with. A day or two later the computer black screened a short while after starting to mine and more recently it black screen once at Windows desktop.
I've reset the MSI Afterburner settings to default.
I've tried uninstalling and reinstalling AMD drivers from 14.12 to 15.12 and i can't get the rig to stop blackscreening.
I did wonder whether it was because there is no shared driver from AMD that will run both GPU's without crash.
Temps are all within range.
I've seen so many threads where people have suggested undervolting, overvolting, powertuning, adjust clock speeds, I've tried them all and in combination with each other
In terms of the bat file to run QT miner i've kept it very simple, qtminer.exe -s eu1.ethpool.org:3333 -u my wallet address.rig1 -G
I'm at a loss to see what else it could be, i've read almost every thread available and what works for others doesn't seem to work for me?
I'm running two 600W PSU's (one does the MOBO, SSD and R9 290x) and the other is running only the R9 390.
I purchased a dual psu 24 pin splitter which is used to kick the second PSU into life.
I apologise if this has already been solved in another thread, if so i haven't seen it.
Any help would be greatly appreciated!
The overall aim is to test the process and if works but 5 x R9 390's which may remove the driver challenge i currently face running a R9 290x and R9 390...
