I don't know what to think about my GTX 1060's: I had a generic HP with 3GB that regularly got 23MH/s ETH, but my new 6GB Gigabyte card won't go over 21M.

Now, I am getting around 500MH/sec on my second coin XVG, which I was not doing on the 3GB card, but my ETH rate didn't change more than 1% lower.

Strange.  I suppose it's another "silicon lottery" phenom: this has Hynix VRAM, I had Samsung memory on the 3GB card that kept crapping out on me.

Hey guys,
Im new at mining
Currently bought 3 GPU Asus GTX 1060 6GB
and mine on Nicehash
Is there any tips what profitable algo to mine?
and what is good setting with Msi Afterburner for the GPU?
Thanks

sell them for profit. check the ram. change the miner. give them to the needy. mine something other than ethereum.

I bought 1060 yesterday. Guys can you share OC for MSI 1060 6gb armor OC memory type micron..
I can only get 19 mh/s for ethereum and 290 for zcash..
Hope someone can share a good settings to increase good hashrate for ethereum or zcash.. thanks. .

I newly started mining on Zotac GTX 1060 6gb AMP Edition 7 days ago. it has Hynix inside and make me confused .
tried with msi afterburner but it crashes or restarts nicehash excavator. so installed FireStorm and using it since 4 days with no problem.

ETH: Core: +150, Memory: +920, Power: 62%,  Temp: 60 max, Fan:80%, 20.7 Mhz/s (stable with nicehash, nanopool and Claymore)
could increase memory to +935 and power to 65, which increases more heat like; 70

Zcash: Core: +160 memory: 0, Power: 80%, Fan: 80% Temp: 66, 282-290 sol/s
i think speed depends on acceptance...
core can increase to +165. and power to 90% 300 sol/s with not profitable sol/w.

thinking to get one more card so any suggestions ? PNY 1060 6GB OC GAMING Edition or Gigabyte Windforce OC or MSI GTX 1060 6GB OC V2 ?

in order to get more sols you should oveclock your memory as well, not only core, good and pro[erlu overclocked gtx1060 can pus around 330-340 sol/s, which is about 10% more then you have

Thinking about the latest Windows 10 problem with the OS eating 666MB of the VRAM and specifically with the issue on GTX1060 3MB cards -vs- Ethereum DAG stored in RAM, has anyone tried moving the card to something other than the primary? (PCI 0,0,0)

It seems like Windoze would only chew up the VRAM on the first card found, not every GPU it sees.  I don't have my 3GB 1060 online right now, so I can't test my theory.  I know that it's not helpful if you have multiple 3GB 1060s and nothing with 4GB or more.

The extra few hundred mb vram is reserved/in use for the primary video yes. Windows is graphical OS. You can easily check vram allocated in gpuz for example
The rest no such reserve.

Considering first card have micron mem, it's ok. For equihash you can oc a little more core & mem, but not needed. Use dstm miner for equihash algo coins, it gives few % more sol/s than ewbf. BTW, nicehash is hassle free (no worry about pools, wallets, exchanges, etc) but there you are mining for someone else and mining profits can be lower upto 30% than if you mined your currently profitable coins directly.
