That's really neat, but doesn't contradict anything I said.

Also do you perhaps mean Strontium-90? ;)

> Wrong. LPDDR5 and it has its own error correction features (not as robust as ECC but it's still there.)

Their product page lists LPDDR4x: https://www.kyoceramobile.com/rugged-devices/duraforce-pro-3. Unless you have a better source I'm going with the manufacturer on this one.

Source?

>Their product page lists LPDDR4x

Funny because the Qualcomm sm7450-ab snapdragon 7 gen-1 page lists itself as only supporting LPDDR5.

>also do you mean perhaps Strontium-90?

Nope. Strontium-60. 25 year half life compared to Sr-90's ~29. It's what we like to use in real space-environment testing on the ground. Nasty stuff.

>source?

You can actually probe your hardware and see what sort of ECC is enabled on a Droid phone. In this case, in-line ECC, so that means some of the RAM is actually sacrificed for error correction instead of having a dedicated extra chip (256 bit, 240 of that is data 16 bit is error correction.) What's awesome about that is that enabling ECC is simply a bit flip in firmware and you don't need the extra RAM modules installed - the installed memory can already do it. You don't need the extra hardware.

Those pages contain scarce technical information, it would be silly to say that anything not listed there is explicitly not supported.

Qualcomm's leaked datasheet says it supports lpddr4x: https://www.scribd.com/document/868805341/80-26135-1-AE-SM74...

Strontium-60 doesn't exist. It falls completely off the isotope table (https://inframatterresearchcenter.org/IsotopeTable.html). Strontium-82 has a 25 day half-life.

Care to share how? I wasn't able to find anything on the internet and I'd love to know whether my phone has some limited ECC.
