Only if you actually use that much. You almost certainly don’t.

introducing: zram

toss 32 or 64gb at that and call it a day

YMMV.

Big ZRAM absolutely tanks performance for me because it "steals" space that could be used for normal memory.

But if its for squirrling away a bunch of idle processes when multitasking like crazy, yeah, it can be wonderful. Just depends.

I do.

I wish I had 192GB, to be honest.

Same. But more than that - I noticed that my 7700x is a huge bottleneck: desktop CPUs limited to just 2 channels, plus controller in 7700 is kinda meh, so I can't force anything above 5600mt\s with my 4 sticks. Switching to new CPU should allow to increase speed, but will still lock me to 2 channels. So I should've bought cheapest threadripper instead, which allows 4 or 8 channels instead.

Depends what you are going for. 7000/9000 series have way more per-thread performance than threadripper.

Another quirk with single CCD 7000 chips (which I have as well) is that the infinity fabric limits effective bandwidth to the CPU cores. Even with two channels, you hit diminishing returns with higher speeds, especially if you aren't using the IGP.

You can get around it overclocking the IF, but it gets complicated and its much easier to do with 9000 series CPUs.
