Problems with miner...

[ViperCS]

So i started to mine EXP with 2GB r9 270
Everything is good till i start mining, it goes okay for some time then my gpu like retarts, screen turns black, everything lags, and goes back to normal but hashing goes down to 0 and i need to reset miner.
My setup:
MOBO: ASRock N68C-S UCC
RAM: 4gb ddr2 dual
CPU: Athlon ii x4 620 (4x2.
GPU: r9 270
HDD: Old 128 gb hdd
Miner setup ;
ethminer -G -F http://exp.suprnova.cc:3000/ViperCS.ViperCS:x/20
setx GPU_FORCE_64BIT_PTR 1
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

I tried running cuda and opencl and both are the same
i tried to overclock (overclock down sorry english is not my 1st language :/)
Also after this problem win10 gives me message that RadeonWATT or something stopped working or something like that. I dont see this program on my pc also...
I did try old and new drivers, the same problem.

What to do? :/

Sounds like the driver is crashing I would uninstall the driver in safe mode using DDU and then reinstall the drivers. You also don't need cuda for AMD cards so uninstall that as well.

Also i tried other miners and games on full settings, crashing only in ethminer mining exp

Your miner settings could be too high. Try backing off the GPU core 10 MHz and the Memory clock 50 MHz, or lowering the intensity. Also check the cables and connectors on the card.

Tried both.

If you can try the card in another machine.

Can i somehow make miner restart when hashing power is 0?

Or add to start script, thing that will restart every like 30 minutes?

NVM I did the thing. (restart every 30 mins)

NVM I did the thing. (restart every 30 mins)

Efficiency with that is nearly 0...
i get like 0.02$ per hour with reset every 30mins.
With other miners as i said its all good but only with that which i use...

I tried changing few drivers and everything.
Tried changing intensity for dag.
Please help :c
