I am using Zotac 1060 AMP! 6GB cards on several rigs with Asus Prime Z270-A and Asrock H110 Pro BTC+ boards. All my cards are with Samsung memory which is great for overclocking the memory compared to cards with Micron or Hynix memory. My cards with Samsung memory can OC to over +1800 on linux (+900 on windows) while the few other brand cards I had (and returned) with Micron memory could only OC to +1000 (+500 on windows) and weren't much stable.

Few people asked for settings for 1060's, here are mine:

Mining ETH only with Claymore 9.7 and 9.8 (same MH/s)
Power limit: 76 W
Core OC: +100
Memory OC: +1820 (Samsung only, don't try with Micron)
Temperature setting: 54 C (fans run at 50-70%)
Getting 25 MH/s per card (3 watts per MH/s is pretty amazing)

By no means these are final settings, there is still room for improvement... I am testing +1850 memory at 75 W power limit. Do not go below 75 Watts on power limit setting, hashrate starts dropping a lot. For ETH (and similar) there's no need to go above 77 watts for single currency mining, there's no gain whatsoever.

Thanks for the feedback - I would love to discuss more as, while I cannot seem to get more than 21 or so per 1060 (while I am not sure what the memory type is yet, I feel like I should be able to get more than +600-700 in Linux for any brand).

The reason for the panel upgrade is that I am out of breakers entirely, and my panel doesn't support half-breakers. So really, I will be having a 200 amp panel with additional space installed, but keeping my service at 100 amp for now, Then I'll have new outlets added on separate breakers, as the goal is to increase beyond the 26 cards I am running now.

If I may ask, since your pushing 1060's on the same boards:
- Do you have them full (using all 13 slots)?
- What processor are you using? I did not think it mattered, but am trying to pinpoint any differences).

If you don't mind, I may have more questions about your rig, either in this thread or outside of it. Either way, I appreciate the information.

To get the memory type you have to install the card in windows machine and run GPU-Z tool. To my knowledge there's no such program that can identify memory brand under Linux.

As I mentioned I had few cards with Micron memory and I was able to OC memory to +500 under windows (which equals to +1000 under Linux). I never had cards with Hynix memory but I read that's the worst brand to overclock. I hope your's are not with Hynix which could explain the low OC and the problem lies somewhere else. Have you tried setting PL to 76, core to +100 and memory to +800? See if that's stable, then increase the memory by another 50 and so on until the rig becomes unstable or crashes.

Yes, I have all 13 slots filled on the asrock boards. 8GB of DDR4 memory. 2 x Corsair HX1000i power supplies per rig (it is overkill but you need lots of PCIe and Sata connectors for 13 GPU rigs). The CPU's are i7-7700 (also overkill, but I got them on sale and I plan to utilize them for CPU mining when I find some spare time to experiment). On that note, two of my Asus Z270-A are running with Celerons G3900 and those are not very stable, one is running on Win 10 and the other on nvOC-0018 with same settings and same MH/s, no difference between windows and Linux at all, although the windows machine is running little bit cooler with lower fun speeds (I suppose that's driver issue, or maybe Maxximus' temp control is not on par with Afterburner, hehe). Although both win and Linux machines with Celeron CPU's are hashing same per card as the one's with I7's, they are occasionally being restarted by watchdogs, or they completely freeze and have to restart them every few days. I tried lowering the OC on them but it didn't help. The first chance I get I will replace the Celerons with at least i3's. Although the mining community recommends Celeron CPU's at large to cut costs I would not recommend that garbage of CPU to anyone, not even for web browsing...

I agree with leenoox. I have tested a spread of CPUs on 13x rigs; the CPU makes a significant difference in stability; please don't use celerons with 13x rigs.
