For Monero, the hashrate under Pool Info is not correct, it says 19.145815 kH/s, but it should be 19,145.815 kH/s

Why is Monero unfair?

Simple answer: what will you do with P106 afterwards? No one will buy it. Regular 1060 can be sold and still used for gaming.

Yes, Hynix has bad timings. Hynix usually also do not go beyond +600. Samsung can go up to +1000. If you have set your cards to +1050, this could also explain bad performance, if the clock is too high, ECC correction will take place which then drops performance. I have my 8 Samsung running stable at +800, did not test any further...

Nvidia BIOS is encrypted, no chance for any tuning besides raising memory clock. Getting other cards or living with the below average hash rate is the only option for Hynix cards!

#2 is caused by cards with shitty Hynix memory. No way to solve it. Get cards with Samsung.

#1 and #3: not every board can handle 8 GPUs. Try with 7 and check whether the issues are gone. If yes, try tweaking BIOS to get it stable with 8 cards or get another board. I can report that ASUS Prime Z270-P supports 8x GTX 1060, 6x PCIe and 2x m.2

PCIe Extenders 1x -> 4x is already a problem. Why do people get a MicroATX board with 3 PCIe Slots and then connect 8 cards to it?! Get a proper Full ATX board with 6 or 7 PCIe slots!

Profitable maybe, depends on your power cost. Others might be more profitable, at least if you sell directly.

Almost 1 billion difficulty now... 5 times as high as 3 days ago... crazy.

Read the thread and do not ask questions that already have been answered. Mining to cryptopia is not working.

Can take 1-2 hours until the blocks are confirmed...

Why is the coin value going up that high today against the global trend?

No, looks like you should read the last pages of this thread...

What exactly is the problem with these locked premined wallets (sry for noob question)?

Which rebrand?

First part is clear, but the 2nd not. What do you mean with botnet sell down to 4000sat?!? 

Hi, any plans for adding Sumokoin in the near future?

What do you guys think on the current chart situation of SUMO? There is a clear trend downwards, what's the reason? Missing trade volume due to a lack of exchanges, low interest in the coin, ...?

Then I would go for RX580 or GTX 1070. They have a comparable hash rate if the RX is tweaked, depending on the algo the one or the other is faster. RX580 should be cheaper though. For me (0.30 USD per kWh in Germany) power consumption matters a lot, so the RX was no option as the Pascal based cards are a lot more efficient when fixed to low voltage. My GTX 1060 only use 45-50W for monero mining while producing around 530 H/s, RX570 had over 100W and hash rate was not much better without BIOS mod.

Depends on your goal: get a maximum hashrate with as few cards as possible, then you should go for Vega or GTX 1080Ti. If you want to get the maximum hashrate for the money invested, then cards like the RX570/580 or GTX 1060 are a better investment imho. But you then need more systems for the same hashrate of course, and each system brings additional costs for board, CPU, PSU etc.

Consumption per card probably is rather 40W than 34W as you have to add some watts idle consumption. 34W is just the delta between idle and load.

Have you tried memory OC on these cards?

9x GTX 1060 3GB with mem OC +800 (go for Samsung) you will get about 4860 H/s with a power consumption of 480W when fixed to 0.8V. I have a rig with 8 of them, doing ~4200 H/s at 430W at the wall.
I also tested with RX570 which did not respond to memory OC at all and in the end did not deliver better H/s than the GTX 1060 with mem OC, but consumed a lot more power, so no choice for me.
