That's a much weaker statement than "the primary source of uncorrelated bit flips is cosmic radiation".
The word "uncorrelated" is doing a lot of heavy lifting in that claim. Most DRAM error sources are pretty clearly correlated, if you're paying any attention.

How do YOU propose doing this when most computer "experts" have never used ECC RAM and when it's only available in high end specialist systems that aren't on sale in regular computer stores? I think my knowledge of the topic is pretty good but I learned from this discussion that almost all AMD CPUs support ECC RAM and you apparently just need a motherboard to match. When accompanying people who were buying "gamer" PC…
It's simply none of my business whether or not someone does the homework to understand what kind of RAM they should buy. I bothered to inform myself; they can, too.

If it's none of your business why are you getting so involved in this discussion?

What you're actually saying is that I shouldn't be allowed to determine what kind of RAM my application needs. Instead, you are saying that someone with a gun should dictate this choice to me. That's what we mean when we say that people with your point of view are promoting nanny-statism. It amounts to infantilization of adult consumers and subsequent disempowerment. Occasionally such legislation can be justified, as…
> People can and should be educated -- and expected -- to make their own decisions about things like whether they need ECC RAM. So you think its realistic to expect the average consumer to assess the pros and cons of using ECC RAM? We could solve this by better information which addresses your concerns about it being nanny statism. We would need it to be something that consumers understand - e.g. We could require all…

i have years and terabytes of ECC DDR4 and DDR5 memories, UDIMM and RDIMM, with edac enabled all this time, and i have literally never once observed a single error correction. however, (1) i built all these computers myself (2) the servers are located on the middle floor a thick, concrete multi-story warehouse-to-office conversion. as others have said, on a correctly built computer, the source of bit flips is cosmic…
It's not just cosmic radiation or improperly built computers that result in bit flips. Row hammer is a thing :)

This is/was classic market segmentation. Want ECC? Pay up for Xeon (server/workstation CPU)
AMD has historically supported ECC on all it's chips. That's changed in the last gen or two where some of the lower end APUs don't support ECC but the Pro APUs do and all the ryzen stuff (5, 7, 9) support ECC if you get a motherboard that supports it.

Theoretically, though I’ve not seen any certified builds. At least advertised. Do tell who offers an ECC laptop PC at a reasonable price.
But it's definitely possible, I have an ECC setup on my desktop and it's caught a memory error or two over the last few years.
This is not a very good post. Claiming that every issue you've experienced is from seating errors? Come on man, at least deliberately reproduce that scenario once. I've tortured motherboards for fun and never managed that on purpose. We did pry every cap off of an old K6 board while it was on and... it just kept running. It didn't come back after we turned it off The amount of time it takes to reseat memory, even if…
