Issues with various miners (Ethereum)

[tombro]

Hi all,

I'm trying to mine with my 1070 and two 1060s. The first miner I tried was Ethminer using OpenCL. When I use this miner with more than 2 gpu's my i5-4690k spikes to 100% and Windows10 becomes really slow and feels unstable. After a while I get an error saying "clenqueuemapbuffer(-36)". I tried to use the Cudaminer, only to find out I get an error "GPU 1, GpuMiner cu_k01 failed 77, an illegal memory access was encountered GPU 0, GpuMiner cu_k1 failed 77, an illegal memory access was encountered". The miner shuts down after that. The same error occurs at Claymore's. Claymore's miner does reboot after an error, but it destroys my average hashrate. Does anyone know anything I could try to fix this?

Thanks!

EDIT: Swapped mobos (MSI Z170a gaming m5 to Asus Z270-a prime) haven't had ANY problems ever since. Faulty mobo probably.

Are the cards overclocked, see if it isn't too much. Also check your PSU, can it handle them all? What error exactly do you get in Claymore? Give some more details about the system too.

I'm using Claymore in Windows 8.1 with 2 1070's and 2 1060's - all are core underclocked to -100 and memory overclocked to +750 using MSI afterburner..
 
I'm using an 850W PSU and the whole system is running at around 600W.

So there are a few differences to your system but mine is very stable, hashing at about 107mh/s.

1070 should be doing about ( from what i read and watched ) 130 watts per card
