Let me kmow where I can get ECC RAM that's only 12% more than the price of non-ECC and I'll strongly consider it the next time I do a build. (Otoh, prices are high, so I'm not building anything for a while unless stuff breaks)

For second hand gear RDIMMs are significantly cheaper than UDIMMs. As all RDIMMs have ECC that means generally ECC is cheaper for second hand systems.

Aliexpress had $50 single socket motherboards for Xeon E5-26xx CPUs and $150 dual socket motherboards last time I checked that use DDR4 RDIMMs.

Before the prices went up due to AI foolishness DDR4 RDIMMs were $1.20AU/G means means something like $US0.80/G.

Some years ago, it was easy to find ECC modules with a so small price difference.

From that time, I have a few old computers with 64 GB or 128 GB of DDR4 ECC memory.

Unfortunately, after the passage to DDR5, DDR5 ECC UDIMMs have become hard to find, and even when you could find them, the price difference could be as high as 30% to 50%.
