Intel 9th Gen LGA1151 Processors Support Up to 128GB of Memory
Intel's 6-core "Coffee Lake" die was essentially a "Kaby Lake" die with two extra cores, and no physical changes to other components, such as iGPU or uncore. With its new 8-core "Coffee Lake" Refresh silicon, Intel has turned its attention to not just increasing the core-count, but also improving the processor's integrated memory controller, in addition to hardware fixes to certain security vulnerabilities. The 128-bit wide (dual-channel) integrated memory controller now supports up to 128 GB of memory. Intel's current DDR4-capable mainstream desktop processors only support up to 64 GB, as do rival AMD's Ryzen socket AM4 processors.
Support for up to 128 GB explains the emergence of off-spec memory standards such as ASUS' Double Capacity (DC) DIMMs. Samsung is ready with a JEDEC-compliant 32 GB dual-rank UDIMM memory module for client platforms. Introduction of 32 GB UDIMMs also comes amidst reports of DRAM pricing cool-off through 2019, which could make 32 GB dual-channel memory kits consisting of two 16 GB UDIMMs more affordable. The increase in maximum memory amount could also indicate Intel's seriousness to introduce 3D Xpoint-based Optane Persistent Memory modules as alternatives to DRAM-based main memory, with higher capacities compensating for worse latencies and data-rates compared to DRAM.

And even if so, where do you even get consumer based 2 x 64GB enthusiast kits? Doesn't seem too exciting, and something more to just fall on deaf ears.
edit: A damn eyesore looking at all of my empty RAM slots though.
I don't know how many copies of Crysis 3 he has, though ... so there's that ...
On a more serious note, if RAM prices weren't so obscene and your build could support it, would you get 512GB RAM?
As for the topic, i'm guessing very rarely will a user require such a huge amount of RAM: on a different platform (server like) it's an completely different story, though.
I've never been one to have a bunch of tabs on my browser. I think I'm stuck in the 90s, as far as that goes.
Any ram over 128GB i must use ECC RDIMM. Data is more valuable.
Why Intel Created The C232 And C236 Workstation Chipsets
www.tomshardware.com/news/intel-c232-c236-chipsets-xeon,31051.html
I do think the segmentation of Skylake-X and Xeon-W is unnecessary though; two workstation platforms with very similar features. AMD did at least make a smarter choice in this instance.
32 is nice. 64 would be better...
mainly needed for models and simulation.
Then again dual CPU and 128 would be nice.... one day maybe
