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...

Any thoughts would be greatly appreciated.
I've also had this issue when there was a problem with the romex cable supplying the riser.
I wanted to check but even though the gpu is powered by the psu should I also be connecting the powered pci molex connection to the psu as well? I'm going to spend more time tonight trying not to establish what the critical error 41 means in the event viewer, it references kernel error, but looking into that it looks like a very general error and difficult to pin point the reason behind it....
both cards are powered by the pcie 8 & seperate 6 pin direct to the psu... (completely seperate cables rather than using the same wire with both on). They are powered risers.... I'm not using the power via molex. so to clarify do the 390 and 290x both need an 8 & 6 pin connectors along with connecting the molex on the powered riser?? Worried I might fizzle something.... Admittedly when I mined for other coins with the 290x I only ever connected the pcie 6&8 pins directly to the psu. Even though the riser has the seperate molex I never used it and I didn't once have a black screen or if I did it was because I'd pushed the intensity/clock settings up slightly too far...
I'm thinking I'll check the ram, swap the psu (although both fire up) check the 24 pin splitter (which is to fire the second psu/gpu). Reinstall the drivers I have tried everything from 14.12 to 16.3 (think that's the most recent Crimson one) from AMD and all drivers between. I use ddu in safe mode to remove previous driver... I could try flashing the gpu with the most recent vbios.
I am at a bit of a loss really...
Problems only started when I added the second new 390 8gb, brand new be quiet 600w psu to power it. I don't know whether the two cards (albeit) from the same family don't like being on the same driver set...
Any comments/suggestion very much welcome!
I'm still a bit confused won't I short the gpus they each have an 8 & 6 pin connector from seperate psu's and then connected the powered riser molex to the psu (as you suggest) at the same time? Currently the powered riser is effectively unpowered via the molex. I just don't want to make a mistake and fry either/both my gpus.
I appreciate your response it's good just to discuss this as it's very frustrating.
Maybe this is where I've been going wrong I should have also connected the powered riser molex to the psu via one of the specific cables? I just didn't want to kill the gpus lol.
I'll try again today to see if I can get the 290x running. Thank you for your thoughts! I appreciate the support.
But I'd rather replace ram without knowing for sure or bypass the 24 pin to jump the second psu and replace them both with 1000-1200w psu... But for a good one its around £150 ish... The final option is to buy another r9 390 hoping that will work as it's exactly the same card rather than mixing the 290x and 390 msi cards.... I'm running out of options, other than stop wasting money. Thoughts?
eliminate the cheaper elements before working up to a bigger chunk of ram and or a 1200w psu... Thank you for taking the time to read my elongated thread. It's greatly appreciated !
The 390 by the way is purring at a steady 33M/hs
