ECC support is an actual +10-20% cost in materials for the motherboard and DIMM manufacturers. Also, ECC errors are basically non-existent on desktop/laptop workloads. ECC is worth the extra cost in servers, but for desktops and laptops, the market got it right.


A consumer PC should see a single bit error roughly once a week. That’s hardly non-existent

Here's a few references

Worst case those just trash some family photos of a dead relative. Hardly anything important.
