There might be some way to make use of it.
Linux apparently can use VRAM as a swap target:
wiki.archlinux.org/title/Swap_on_video_RAM
So you could probably take an Nvidia H200 (141 GB memory) and set it as a high-priority swap partition, say.
Normally, a typical desktop is liable to have problems powering an H200 (600W), but that’s with all the parallel compute hardware active, and I assume that if all you’re doing is moving stuff in and out of memory, it won’t use much power.
That being said, it sounds like the route on the Arch Wiki above is using vramfs, which is a FUSE filesystem, which means that it’s running in userspace rather than kernelspace, which probably means that it will have more overhead than is really necessary.

ECC might be slower but if a ton of it floods the market all at once it could still be a good 2x64 GB purchase. Plus, it’ll be great for selfhosts even if not for gamers.

You can’t put the kind of memory used in servers (registered ECC dimm) into normal/personal computers. It’s not just that the ECC won’t work, they don’t work at all.
That’s different with unregistered ECC dimms, those will work (at normal spec speeds), but the ECC part will just be unused. These are in the minority though for servers, in practice they are more used in workstations.
