Hi here, Nvidia RTX 20xx series will be supported?

Whats the driver on the 1050 and 1070 rigs?

Try the 1.3 version, and 398.11 driver.

Tried the 1.4 too, but i have the same problem with it, after 30-60 min miner exits and not restart, going back to 1.3

After 10 days running with Coolminer 1.3 the stats:

Windows 10 Pro 1803 - 398.11 NV driver

2x1070 MSI Armor
1x 1080 Gigabyte 1080 Aurus
3x 1080Ti Inno3d Ichill x4
Overall average: 16,273MH/s with average 717W power consumption at the wall, and 0,3-1% stale share on intensiti 19.

Are u upgraded your Nv driver above 390+ im using on one rig with 397.31 an another rig with 398.11 and no problem.

Version 1.3 after 24 Hours still working stable.
Config: plimit 50 all cards, GPU+0mhz, mem +0 mhz , i=19
Geforce Driver: 398.11 fresh one
2x MSI Armor GTX 1070 @~1870khash/s
1x Gigabyte GTX 1080 @ ~2560khash/s
3x Inno3d Ichill x4 1080Ti @~3440khash/s

Overall ~16,5Mhash/s and still stable, power consumption the whole machine: 717W at the wall.

With CCminer 2.2.5 overall i had ~14,3Mhash and 700W power consumption.
So i think overall i have 13%+ mining power, good job Ryzen2700x .  

Testing an MSI Gaming X 1008Ti with Plimit 50, i=21 , GPU+100mhz @2Ghz, and Mem-500 and the result is:
Driver the same as the 6 card rig.
[2018-06-08 20:37:56] GPU #0: 1998 MHz 27.76 kH/W 127W 62C FAN 35%
[2018-06-08 20:38:39] GPU #0: MSI GTX 1080 Ti, 3538.46 kH/s

Im using the 397.31, stable whit this after 7 hours.

Tried 1.3 stable for me with 2x1070+1x1080+3x1080Ti overall @17MH/s
