I thought I'd give you an update. You may remember that I was perplexed by the fact that my FX8350 would not wake from sleep, requiring a complex ritual every time (hard off, CMOS clear etc). I thought it was approaching end of life and decided to upgrade to a Ryzen 1700X before the appearance of the magic smoke. I got the 1700X, an Asus Crosshair VI, cheap Corsair DDR4 2x16GB 3000CL15 which is dual-rank and runs at 2667MHz and a nice Fractal R5 case.
Unfortunately, I got the exact same problem with the Ryzen system. It wasn't a software issue because the problem existed on both Linux and Windows. Given the fact that I only kept specific pieces from the previous system (PSU, HD, SSD, GPU), I thought that it had to come from these pieces. To make a long story short, after a series of tests, I finally discovered that the PSU was the culprit: even though the sense voltage was correct at 3.3V, it somehow failed to detect the change (or some protection mechanism stopped it from turning on) when it should have. I inspected the PSU capacitors visually and couldn't find an obvious cause but the problem went away when I bought a new Seasonic Prime 750 Titanium, a product that delivers, according to Anandtech, a near mythical performance (http://www.anandtech.com/show/11252/the ... ply-review
The old PSU was also a Seasonic unit, a 7-year old X-750 Gold. I expected it to last a little more, but since the guarantee was for 5 years, I suppose I got my money's worth out of it.
What struck me immediately with the Ryzen system was (a) this was the least painful system upgrade I've ever done,(b) sound quality was noticeably better (the Crosshair VI has some nice audio circuitry) and (c) it is really cool and quiet.
The Ryzen system is noticeably faster in almost anything multithreaded, especially for code that runs using the AMD math libraries (multithreaded) and compilation. Games are probably slightly faster than with the FX8350, but I couldn't say. It already was plenty fast for me so I didn't notice a big difference (I'm currently playing Witcher 3). Win 10 startup is probably a bit faster, maybe because the SATA is also better (SSD speeds have improved under Samsung Magician). I will post a series of bioinformatics benchmarks at some point but I'm still optimizing some parameters for the new architecture (number of threads, recompiling the tools--btw Ryzen lacks some of the FX8350 instructions and code that was specifically compiled for the 8350 does not run, it has to be recompiled with different flags).
Anyway, if your system fails to wake up from sleep, you should consider testing with another PSU.
