AMD's first and second generation Ryzen don't overclock much beyond their stock boost frequencies, so overclocking them is mostly not worth the trouble. You end up using 20-50% more power for 3-10% more performance.

I have to disagree...at least on the non-X CPU's. My 1700 base speed is 3.0Ghz (all 8 cores/16 threads continuous heavy encoding load) and boosts one core to 3.7 for at best a few seconds at a time, even under a 240mm liquid cooler with core temps running around 30-35C. That's pretty paltry boosting...essentially, it's a 3.0Ghz processor. Yet, this system safely holds a sustained overclock, all cores, to 3.95Ghz, at heavy load.
That's a 31% overclock, pretty good by any standard, against the base clock. And 7% overclock against the
one core/two threads only boost. Still not shabby and a substantial time saver for handbrake encoding tasks. Which are of course all-core, heavy loads where boosting performance is essentially meaningless since...it never boosts!
Any 1700 should be able to see a 3.9G overclock with safe voltages on a decent motherboard. But even a very mild 3.8G, still a 27% overclock, is well worth it and incredibly easy to get. Just increase VCore to 1.375, and multiplier to 38.0. It's done...probably more voltage than needed but still very safe for Ryzen.
