Hello,

Just wondering ... did somebody already tried to overclock an STM32 (F2 series for example) ?

What max clock can we achieve before the chip blows up (with correct flash wait state) ?

Thomas.

Well, I assume the OP as grown-up enough to take responsibility for his actions.

Operating something (including a STM32 MCU) outside it's spec may actually break it.

And if it breaks, it might have to do with exactly this fact.

As long as there is no whining/complaining, it's totally up to him, and ok for me ...

Perhaps unwise to suspect that Erik/I write, ''just'' for o.p. 

There are consequences for, ''outside spec operation.''  And - these have now been listed - let the (MCU User) beware...

Well, I assume the professionals to know, and the o.p. to ''don't care'' (more or less) ...

Surely, for a commercial device, the legal consequences far outweigh the minute performance gain of overclocking.

Actually, a few years ago at 8052.com there was a post ''we have produced hundereds of these devices, now suddenly the newly build does not work''

after a lot of posts it was revealed the 'working' devices were overclocked

And - at some point - should any reasonably experienced investor or VC - ''consider'' your project - their checklist will search for any such, ''out of spec'' operation. 

If such ''improvements'' are admitted or detected - stand far clear of the exit door...
