Hello guys!

I will have 12 graphics cards and I want to put them on a mother board with 12 slots.

I want to put them on an Asrock H110 Pro BTC+.
I have two questions:

1. The graphics cards are dual, which means that Windows will see them as 24 cards? Is it ok? Would I have problems because of that?
2. Will it be enough to have 8 GB RAM? Or it doesn't matter when it comes to RAM?

What cards are you buying? Aren't they Asus Dual?
8GB RAM is good enough, I would say you should be fine with 4GB too.

sometimes for some coins 4GB  is not enough,  so I will recommend to take 8GB and set good chunk of your hard disk drive for virtual memory, like 40-50GB
in this config you should be pretty ok.
on my rigs with 7 cards ( 1070) I have 8Gb ram and all is working smooth

I have the same configuration and 8 gigabytes does the job without any problems.
When i started building rigs i used 4 gigabytes, but sometimes i had problems with specific algos or miners and that is why i started using 8 gigabytes.

Since no one gave you a clear answer:
4Gb is fine in windows as long as you don't forget to increase the virtual memory (aka swap file) to at least 16GB.
To be honest the cost of ram is so cheap that's most of us don't bother with 4GB.
But
i noticed my AMD rig needs 8gb, 4gb even with virtual memory at 16gb is not enough, always get warning msgs and is generally slow over rdp, my nvidia do fine with 4gb

Go for 8gb of ram i started with 4gb and had problems and increased to 8gb and solved some issues. I have ASUS dual 1060’s and the dual refers to the FANS not the fact that windows sees them as double.

if you are building a rig with 12 or more cards go for a min 8GB , you going to save a lot headache in the future :)
also dont forget to increase the virtual memory for 16GB+
What kind of "dual cards" are you going to use ?

Maybe word 'Dual' in graphic card name means 'Dual fan cooling', if it's not a real dual-gpu like 295x2.
Many mining rig runs on 4gb ram, 8gb is sufficient.
You should consider that Windows only support max 8 cards per gpu manufacturer. It seems that AMD is going to make drivers that supports 12+ gpus on Windows, but you should check on it.

That is not correct :)

It is a real dual gpu. I am talking about Radeon pro duo.

Graphics card is the core media for doing BTC Mining.

8GB RAM is capable to process the performance of 12 Asrock H110 graphics cards.
However, it would be nice to use nvidia instead of AMD, very light nvidia be able to run it well even though RAM is in use only standard capacity RAM (4GB).

All of the discrete GPUs on the market are designed by one of two companies: AMD or Nvidia. Their GPU designs are sold by a wide range of resellers, like cool lighting designs, water-cooling options, or features like LED lighting. For over a year, Nvidia has the upper end of the performance market completely to itself, but now that AMD's RX Vega cards are on sale, you're no longer limited to Nvidia if you're spending $ 300 or more on a GPU.

GPUs from these two companies are typically grouped into families of graphics processors, all of which share some common naming conventions. For the past eight years, Nvidia has followed a common format of "prefix-model number-suffix." If two GPUs have the same model number, like the GeForce GTX 750 and the 750 Ti, the suffix "Ti" denotes the higher-end part. Nvidia has also been known to use an "X" or "Xp" to denote certain extremely high-end parts. AMD's nomenclature is similar, with a prefix "RX," the three-digit model number, and, at times, a suffix (typically XT or XTX). Be advised, however, that these are rules of thumb rather than absolutes.
However, you need to remember that both graphics cards have their respective advantages and disadvantages in each series, so do not equate them in general. And also do not forget, before deciding to buy a VGA, make sure your motherboard support with VGA you want to buy it. There are several VGA slots that are usually on the motherboard, such as PCI Express, PCI, and AGP slots.

As far as I know, the price of RAM is so cheap compared to the price of Asrock H110 graphics card, why do not you take the initiative to increase RAM size?... with high RAM capacity, then your 12 graphics card performance will work better.

It is not true. Ram (and SSD) price increases every day since years.

So the question is relevant...

8GB RAM will be fine.
