> Is it possible/likely that ST's testing detects failure at the ''extremes'' - temperature, voltage etc?

absolutely. it's their job to guarantee the ranges, and testing is the only way. (except for the orwellian ''not fully tested, guaranteed by design'' parameters, which are thus not really guaranteed... 🙂 )

> would you forum users even attempt use of unspec'ed ram?

*never* in production. if the success of my endeavor rests on saving 20c per item I'd be doing something else. and since it doesn't, I wouldn't run unnecessary risks.

Hi,

Yes For sure ! I mean the extra RAM size from 10 to 20K is not functional , I guess all of you have understand this 🙂

Cheers,

STOne-32.

Thank you STOne-32. When you say ''this RAM area is not ensured by ST to be functional '' , I really hope you mean RAM area between 10k and 20k and not the first 10K area!!

Ride and IAR users, make sure you have the RAM configuration right !! This could be wrong on many of the chip variants.

I have been using Ride, and this is how fixed it.

Change the line ''RAMSize =20480'' to ''RAMSize =10240'' in STM32F101V8T6.sim file (in your ''....\Ride\Sim\ARM'' directory)
