This is the PCPartPicker chart that I monitor: https://pcpartpicker.com/trends/price/memory/#ram.ddr5.5600.... - $900 for 2x32GB, used to be $200 a year ago.
The memory in the PC I put together early last year is now worth about three times the total cost of all the parts I used to build the thing. It is absolutely crazy.
I regret not building the PC when I was looking at it. It's not a money thing, at the end of the day, but I can't bring myself to do it.
I had it all priced out, but a bunch of birthdays in my family were coming up and I felt like I shouldn't buy something for myself if it's really their time.
My old laptop will have to cut it for a while. :-)
At least it seems to not get worse.
Yesterday I did a price check on the PC I built two years ago. It went from $2300 to $3650. The bulk of that increase was that the ram went from $210 to $940. Its now more expensive than when DDR5 was new.
