Having some issues dual mining and was hoping someone could help me out here. I have a GTX 970 using drivers 347.88 on Win 10. Overclocked just mining ethereum I am getting almost 19Mh/s. When I try to dual mine ethereum and siacoin my ethereum hash rate drops in half. Dual mining I only get about 9 Mh/s for ethereum and about 95 Mh/s for siacoin. Im using this string in my bat file

Code:

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
EthDcrMiner64.exe -epool us1.ethermine.org:4444 -ewal address.worker -epsw x -dpool stratum+tcp://sia-us-east1.nanopool.org:7777 -dwal address.worker -dcoin sc

Any help or suggestions are appreciated.

lower the intensity by hitting "-" while the miner is running until ether hashrate is back at 19mhs then run the extra command

so say the intensity works at 17 use the following in bat

use "-dcri 17"

Ok this kind of worked but not really. I had to go down all the way to "-dcri 1" and I was still .5 Mh/s below normal and my sia coin was only 6 Mh/s .... lol . Another issue I am having is this error in the console

Code:

GPU 0, GpuMiner cu_k1 failed 73, an illegal instruction was encountered
GPU 0, GpuMiner kx failed 1
GPU 0 failed
GPU 0, GpuMiner cu_k1 failed 73, an illegal instruction was encountered
GPU 0, GpuMiner kx failed 1

This happens single mining if my memory is overclocked too high (anything over +325 in precicionX) and seems to happen anytime i try to dual mine overclocked at speeds that workk fine single mining. When this happens and the miner restarts then my hashrate drops by 50% and the only way to fix it is to reboot. I looked in the windows event viewer and i see these errors

Code:

Event ID 13 from source nvlddmkm

Im not sure if the problem is my card, drivers or something else. I use this card overclocked at +140/350 when gaming and its been rock solid, but mining not so much. Had to drop the memory overclock to +300 single mining so it doesn't crash overnight
