Ok so My motherboard supports up to 32gbb DDR3 1866mhz ram..the thing I don't get is my board only has 2 ram slots and I have never seen a 16gb chip so how can I get 32gb in it? not that I want to I'm just curious as to how they came up with the limit

That link is ECC ram for servers, I don't think it will work in your mobo, and if it did, it would be a little slow.

Often times, they'll list ram as the theoretical maximum: as though such a dimm existed.

Many modern motherboards include support for 8GiB ranks, which at two ranks per DIMM (dual-rank) allows for 16GiB per module or 32GiB in a dual-channel platform with one DIMM slot per channel. As it stands the maximum density of consumer UDIMM (Unregistered DIMM) modules is 4GiB per rank, which allows for up to 16GiB in a platform with two DIMM slots. RIMM (Registered DIMM) modules are available in higher densities, but these are typically not supported by consumer platforms and are not available at high speeds.

So, the 32GiB value is the motherboard manufacturer's way of saying that the board will support 32GiB of installed memory if DRAM manufacturers eventually release 16GiB UDIMMs for consumers.

1x16GB DDR3 SDRAM.

As said it's available as ECC for workstations etc. It is however coming in the near future and will work on your PC at some point.

Even if it launches in 2014 the price might be significantly higher than 2x that of an 8GB module.

Probably a good idea not to comment on any thread without reading it immediately before.

I've been called a TROLL many times simply because someone added a comment that came in while I was creating my answer. There are quite a number of jerks around.

Anyway, cheers.
