Yeah, 512GB was a game changer for servers... with DDR3...
And that wasn’t even where it topped out, there were servers supporting 6TB of DDR3 in a single machine. DDR4 had at least 12TB in a single (quad-CPU) machine that I know of (not sure if there were any 96*256GB DDR4 configs). These days, if money’s no object, there exist boards supporting 24TB of DDR5. I think even some quad-CPU DDR2-era SKUs could do 1.5TB. 512GB is nothing.
