The CPU A10-5750M which you mentioned  is a more recent one (newer than my Phenom 2 X6).

It is on a more modern 2013 platform, mine is an AM3 Socket of 2010-2011 years with a corresponding old chipset:

* North Bridge: AMD 785G   
* South Bridge: AMD SB710   
More details about my motherboard can be found at:
https://www.gigabyte.com/Motherboard/GA-MA785GMT-UD2H-rev-10#sp

Though it is listed as supported on Coreboot supported hardware list, I am not sure how well DDR3 RAM is supported by Coreboot on this board.
Does it work with a maximum amount of RAM which the board can handle under its default BIOS firmware or only a few gigs work like 1-2GB?

I can't say about those AM3 boards but my coreboot'ed AMD Lenovo G505S
  is working fine with 16GB DDR3 installed. Maybe you could check if
  they have a similar CPU architecture (G505S A10-5750M is Richland) and
  also check the similarity of their FCH aka "southbridges" (G505S has
  Bolton M3), while waiting for a more helpful answer from someone more
  knowledgeable (+ could check if their board_status reports contain a
  kernel log where you could check the size of installed RAM)
