I've set the UEFI memory menu to 'Automatic', so I expect that when I start compiling stuff it will increase to higher settings. > As for why it's not reporting the product, vendor, and s/n's > properly, I'm not sure.

I've swapped them and I can see that lshw displays exactly the same information, so it seems like a MoBo issue. Hmmm ... I know now that the memory is OK. I'll finish the gentoo installation and then I will flash the UEFI firmware with a more recent version to see if it is caused by dodgy firmware. Thanks for your help. -- Regards, Mick
