I'm curious what the actual manufacturing costs for ECC DRAM is compared to regular DRAM. Is it considerably more expensive, or just the usual over-charge because it's better?

It has another error correcting chip on DIMM, 9 total instead of 8. Don’t be fooled by on-die ecc marketing that’s come out recently, you need the 9th chip for parity.

It’s exactly 1/8th more.
