ram Ram expansion card? Snake oil card?

[Trigonomancer]

So, I was looking around the "Mercado livre"(Brazilian Amazon) and I found this thing right here, I don't want to buy it, I just want to know if it's even possible.

Yeah it's possible.

RAM on the expansion card connects to the CPU via PCIE lanes.. 

I don't know why you'd want that? to use RAM as a drive maybe? Make raid 0 or sth crazy.

I don't know, just guessing.

Yep, it's possible.  Just do a google search on "ram expansion card" and you will get a bunch of answers.

For example.

That doesn't look like a standard connector to me, so could be part of a Dell server system rather than really being an expansion card. I know HP has server specific cards for adding RAM. 

 

On mainstream PCs, there's nothing available AFAIK. Even if you used PCIe, the delay would be pretty big for RAM. 

 

EDIT: Looks like RAM expansion cards used to be a thing, but all the ones I can find are like 2MB of RAM
