The article doesn't go into detail about it, but if you go to eBay and find a really old Dell rack server that that does use DDR3 ECC Registered (such as an R910 or R920 with 512GB in it), they have significantly gained in value over the past 12-18 months. Or like an R720 with 256 or 512GB in it. Also major price jump in resale value. That's what we have come to now.
And raw bandwidth is a function of how many channels you've got as well. So a threadripper with 8 channels of DDR4 will run just fine even on heavy workloads.
My old laptop has this exact RAM. Funny thing is that in terms of throughput it's on par with my current one, where I put just one 32GB stick, with one slot left for upgrades.
I still use it occasionally and it's really the old CPU and worn out SSD which slow it down.
Something like 3200mhz DDR4 is still perfectly fine for 90% of consumer use. You really don't need more to look at cat pictures on facebook.
