Hi, I salute you all!
This is my first post here, I have used until now Claymore 11.9 to mine ETH, with all OC and power limit comands wrotten on
.bat file by example:
mclock +780,+750,+780,+750,+780,+750,+780,+750 -powlim -24,-38,-24,-39,-24,-39,-24,-27 and in last period of time, I got alot of
Open Cl errors.
With those settings for memory OC and powerlimit used, as described above, it worked well for weeks, there was used 3x1080Ti and 5xGTX1070 in the rig but in the last period when I replaced one GTX1070 with another GTX1080Ti, to be 4x1080Ti and 4x1070 on that rig, it freeze entire rig after OpenCl error, and the only one solution was to reset rig.
First time I was suspected that forth 1080Ti is bad, but the card is brand new.
I have tested that card on a friend's rig, it works perfect.
I tried to lower mem clocks, also I have managed to run rig at standard settings for all videocards, no power limit, no mem OC,
all stock, the same OpenCl errors at random times period, maximum 10 hours and rig was freezed with OpenCl error.
So OC settings was not the blame for freezing rig.
If I get out one videocard from rig, no matters if is 1080Ti or 1070, (I have tried to get out random 1080Ti and random 1070 card)
just to be only 7 cards on that rig, everything was perfect for days, no any error.
I was out of solutions, the only one was to use just 7 cards on that rig or just 3 1080Ti mixed with 5x1070, the rig freezes with 4x1080Ti and 4x1070...
No power problems as power supplies sums 2500 watts, 2x Seasonic, 1200 and 1300 watts, 4 cards (2x1080Ti and 2x1070) on each power supply, so enough headroom for each power supply.
I have tried PhoenixMiner 4.2c,and all my problems has disappeared!
It works entire days without get any error with all 8 cards, 4x1080Ti and 4x1070!

I tried to use all OC and powerlimit commands on .bat file but doesn't work...
Finally I got to use MSI Afterburner, to manage OC memory and powerlimit too for each card individually, it works great!
Now, my question is,
it will implement in newer versions, options for mem OC and powerlimit for Nvidia cards too?
I have read, those settings wrotten on .bat file, works now just for AMD cards.
Thank you!
