Largest RAM size supported by a motherboard

That would depend on the platform and specific motherboard.
Dual socket Server board (or quad socket) can hold a shed load (1TB?)
The desktop platform will also vary. Are you talking mainstream platform (Z97/Z170) or the HEDT (X79/X99) platform? AMD?

that really doesn't matter much, a commodity PC can be used as server too, if you reboot it once in a while.

single socket board, are there any models I could find online and check the prices?
Server boards? For what platform/CPU??? Sure there is information online!
I feel like we could help you better if you share what you are trying to accomplish. As it stands you asked about physical capacities, and are now on about pricing and boards? We can help you focus your efforts if you share some information.
Good call on the OS playing a part in this!!!

W8 Home is 128GB, 8 Pro is 512GB. W10 Home is 128GB, W10 Pro is 2TB!

On the mainstream platforms with 4 DIMM slots, absolutely. On the HEDT (X79/X99) that doubles to 128GB since on most of those there are 8 slots.

I am not trying to accomplish nothing yet. I am investigating what is the status of current upper bounds of RAM and the costs associated with having this limit increased. For example, if I would want to have a server with 512GB of RAM, how much this setup would cost me? Would it be cheaper than buying 8 cheap motherboards with the cheapest ever processor that support 64GB of ram and distribute the software in 8 different execution units?
Id have to image that a single board and 512GB of ram would be cheaper than 8 different setups. Remember, you have to consider all the other parts involved (8 CPUs vs 1, 8 PSUs vs 1, etc) as well as the time involved to set up and maintain the cluster. You also have to potentially consider software licensing on 8 different setups vs one.

Where can I buy such motherboard, do you know any manufacturer/model?
To get that much ram on a server board, I would guess you need a dual CPU board.
I went to newegg.com and just searched and filtered the terms "dual cpu motherboard" and came up with these results: http://www.newegg.com/Product/Produ...+motherboard&N=100007629 600553802&isNodeId=1

this is what I was telling, single CPU motherboard , and maxing it out to 64GB will always be cheaper than any solution that will push above this limit. The technology is not very well developed to offer cheap large sized memory solution in one box.

SuperMicro quad socket AMD Opteron 6000 series MB's have 32 memory sockets and you could put 32x32GB ECC Reg ram modules for 1TB of total ram. It would cost $7526.40 at MemoryAmerica.com at $235.2 each.
Here is 1 Server MB: Supermicro.com H8QGi-LN4F
Edit: now the largest size ram module is 64GB ECC Reg for Server MB's.

finally someone broke the 64GB barrier!
http://www.pcworld.com/article/2938...s-pc-with-128gb-of-cutting-edge-ddr4-ram.html
But 64GB systems would be still cheaper.

Perhaps. It depends on how much ram you actually need, what boards will be used, the processors, the software that needs to run on them and its licenses, as well as someone to cluster them, power supplies, power used, etc.
As you know, prices go down per stick as its capacity decreases. For example, if you bought one of the boards listed with 16 or 24 slots and put 16GB sticks in there, that is 256GB/384GB pretty 'cheap'. Its when you get into the 32/64GB sticks that prices start to shoot through the roof. So it is situation dependent it appears, particularly when you include TCO (Total cost of ownership) and look at everything else needed to make multiple systems and make them work together. Its an exercise that needs defined parameters (which we do not have any here in this thread) in order to come up with a conclusion/cost.

Found this mobo for ARM architecture.
http://b2b.gigabyte.com/products/product-page.aspx?pid=5422#ov
cost is about 900 EUR. Too expensive. I think I was underestimating ARM, will look into that.

Well, I need > 64GB for networking applications, in those, you have to maximize the amount of RAM and minimize the cost. And I don't have software licenses problems since I am the owner of the software.Perhaps.
