i'll get the same error with daggerhashimoto also
error just showed up in equihash (eqm. GTX1070), so it's not a specific hash algorythm problem, but the nicehash miner itself.
Try downloading
this patch and replace it with the old one in NiceHashMiner_v1.7.4.1 folder.
7 systems it runs fine... even a system with a couple ATI 5850 set at -a 3 for cryptonight.
one system however, which is my main system, it literally shuts the system down after a couple hours. as in, it turns off the power... i.e. hard shutdown.
it's a mixed system with one GTX 170, one RX 470 and two 290X. Windows 10, amd drivers 16.12.2 and nvidia drivers 376.33.
system runs flawlessly with NiceHash Miner version 1.7.3.12.
I have eqm v0.4c and claymore zcash 11.1 dropped in their perspective folders of version 1.7.3.12.
and my monitor (Dell 30in ultra with DVI-D) is hooked up to the GTX1070.
however, when i run NiceHash Miner 1.7.4.0 and 1.7.4.1 (1.7.4.x dropped into 1.7.4.0), the system just shuts off randomly while mining.
Also, if i turn the monitor off then turn the monitor back on later, the monitor blanks out a few times in about 5 seconds before staying on steady. MSI afterburner will show usage drops during this time.
this only happens with 1.7.4.0(x)... the problem is non-existent in 1.7.3.12
