Honestly, I wouldn’t worry too much about it. If its been working fine without issues since 2022, it’ll probably keep working fine in the future too. And if you’re really worried for some reason, you can put memtest on a bootable USB and run a quick test.
Buying new RAM doesn’t make a lot of sense in this climate unless you can snag a good deal imo.
If it works fine, keep using it, but buy a cheap, compatible 3200 MHz DDR4 stick as a tested spare from a reliable online or local seller for peace of mind.
Logic of supply & demand, if ram prices remain this high then less ppl will be building PCs resulting in less demand for other components not affected by this price rise like processors/psu/cabinet etc so their prices will either remain same or might even drop. People can still manage with 512GB/1TB ssd but biggest issue is ram without which nothing can be build & you need at least 16GB ram nowadays to even smoothly run windows 11 without worrying about opening more than 7-8 tabs in chrome. Gamers are the most affected as they typically need at least 16GB vram GPU & 32GB system ram to smoothly play many games.
By the same logic, if manufacturers predict less consumer demand and they slowdown output accordingly, if/when ram becomes affordable, then wouldn’t a sudden demand for other components spike their prices too ?
But yeah, I guess unlike ram, you can still get by reusing old components, cases etc so it may not be a problem at all.
