Great to hear they were nice and fast with the RMA. Never had a dead CPU yet within warranty period here. I too came from a 4790k (with 2400mhz cl-11 ram) to 3700x (with 3000mhz cl-15 ram), BIG BIG difference in over-all snappiness, and this sucker just DOES NOT want to ever 'bog down'. Not even with 16 threads going on 7-zip. With 8 threads going on my 4790k my mouse cursor was 1fps and I couldn't do anything but wait. Now my file-zip ops are done 4~5x quicker PLUS when it's doing it, the system doesn't lag, I can even watch Youtube. Folks don't realize what they're missing. If they can't see the clear performance difference, they likely never should have upgraded in the first place. So when the substation blew up last May (a year ago) and fatally wounded the 4790k's motherboard (it booted, but had no front USB or secondary sata controller which I used for backup drives), it may have been a blessing in disguise after-all. I was annoyed I couldn't upgrade the processor in that intel PC, I would have liked to do so before the substation blew up any-who. Plus, best part, I don't have to overclock this - it does it itself better than I could - I did not have to buy a 35$ delidder tool and liquid metal and delid it - I did not have to buy a 100$ fancy air cooler to cool it (okay, I spent some extra so it had looked nice). Stock cooler does the job satisfactory. I have PCI-E 4.0 later on when I need it *cough* when something actually uses it (I keep mine for years!), lots of USB, 8 sata ports (with no ASMEDIA junk!), 2 NVME ports, and ability for this x570 board to take another generation of CPU should I feel the need to upgrade. Just is nice though that AMD is allowing the user a choice to take the possibly risky route for folks who possess the knowledge about hardware - or the safer-but-more-expensive route for the folks who aren't PC guys. If there is no fail-safe method of reverting the board to it's factory BIOS (the one it shipped with), then you break out your BIOS chip programmer tool and clip it onto the chip and update it yourself. There's also reasons these are typically hidden from consumers. There's always a way. Always. That's typically how they fix boards with a bad flash/bricked. Never accept that there isn't a way. Not once. Unless there's a flaming lake of hot lava between you and your destination and there's no way around, there's always a way. EDIT: Also, AMD right now is trying not to say anything due to not being able to un-say it right now. They have enough issues with that at the moment as everyone knows. They don't want to say something and have all these users say 'but i thought you said I could undo flashing the bios', etc.
