GTX 1060 3GB Hynix memory:
For Equihash algo, some may say "don't tweak the memory, only the core". In case of the GTX 1060 both influence the hashrate positively (tested!).
Hynix can do mem +500, even +600, but errors will start to appear, so stick with +500 as maximum OC.
The 1060 core can be set to 2050MHz with stable performance. Above that... riscky.

So... Fireup Afterburner, make this custom fan curve in settings (check Enable user defined automatic fan control): 30C-20%, 40C-35%, 50C-50%, 80C-80%, 85C-85%. Above 85% fan speed > fan will have a short life!
At GPU OC settings, Fan control > check to be lighted up the Auto button and that little wheel (user defined auto control ON).
Start XMRig to mine some ETN on a stable pool like hashvault, or nanopool, or whatever.
After starting the cryptonight miner, you will see in Afterburner the speeds of your core and memory as stable values (with ZEC miners, the core freq. varries, so you can't tune it properly).
Now, with XMRig on, in Afterburner set:
-unlink power limit and temp limit;
-power limit 85;
-temp limit 80 (or 83);
-core +100;
-mem +500.
You will see the mem has 4303 MHz.
Now you tune the core with +/-5MHz, +/-1Mhz untill you have a stable 2050MHz.
These are your maximum stable OC settings for GTX 1060 3GB.
For ex. a EVGA SC card will need somewhere between core +30 and +65 to rich 2050MHz. MSI +101/+115... etc. depending on the default clocks.
Now, you can shutdown XMRig, and start mining with DSTM's ZM some ZEC or ZCL, or whatever...
With these settings, my rig of 6 GTX 1060 3GB, in Windows 10, with ZM, stays at 300-320 sol/s on each GPU, at a ~1880 sol/s in total.
My temps are at 50-52C, but my room temp is 12-15C.

P.S.: for mining cryptonights with this GPU, set power limit 65, temp 80, core -100, mem +500. It's memory intensive, core must stay underpowered. You can have 480-490 h/s in XMRig.
