For those who find this thread through Google:
 
If you have recently installed Windows 10 on a new system build and have found you cannot play 4K Netflix or 4K in Windows Movies or TV then you might need to install the HEVC Video Extensions from Microsoft in the Microsoft Store. There are two versions: one paid for $.99 and one free. I will link the free one below.

so, i have a ryzen 5 1600 and since i basically game for 99% of the time i get to use my pc (well that and netflix) i decided to play with the SMT setting a bit to see how much i actually gain in games, plus if i can push my oc slightly higher.
so i disabled SMT, kept the same settings exactly as they were (same vcore ,soc etc) and just upped the cpu frequency from 3.9 to 3.95 ( 3.95 used to crash on prime, so i wanted to see if it holds now with SMT OFF).
to my surprise, even though i read everywhere that temps with SMT OFF should be lower, they were actually higher, and not just that, they rose much quicker (time wise). it reached a point where i stopped the test because it started to quickly surpass 70 and didn't show a sign of stopping...this is weird as with SMT on, there is a much slower temp rise as well as a lower max temp in general.
anyone care to explain? thanks.

old thread, but reading it i just couldn't stay silent and not respond. gotta love random internet people throwing some words like voltage, damage, blah blah.
im happy you solved your problem, im sad i didnt see it earlier to save you some headache and anxiety. just for future knowledge, there is nothing you can do in afterburner, NOTHING that will damage your card. your max voltage and power draw is set in the cards bios, you can crank AB all the way up, it doesnt matter, nothing that you do through this program will override the cards bios limits. hell, even if you modify the bios, almost all cards have a predetermined hard limit which is safe  (unless its an LN2 card). nvidia really watches over their products. yeah, so again, happy you found out its the driver, and be careful when listening to some dramatic statements with computer buzz words. im happy you didnt end up RMAing your card , saved you some headache...
 

I will respectfully disagree with you. Sorry.  A decent b350 with air cooling that blows partially on the vrm, and good case ventilation should have no problem whatsoever in running 1800x @stock, specially for casual use/gaming. 

Only if he'll oc it (and overvolt)...otherwise no problem.
6 core chips are also fine on a b350.
But yeah, if you plan to oc an 8 core ryzen, a good mobo is a must. 

ryzen due to 12 threads and upgradability with am4 mobo.
if you have the cash, and want the best of all worlds, go coffee lake i7.
if its strictly for gaming and you dont care to have a shorter "gaming" life span due to 6 threads, and you only care about its gaming performance in the next 2 years or so, i5 is an ok option...would still personally go either ryzen or an i7. i think i5 is kind of a weird choice people make.

Binder nailed it.

If you don't mind paying for a non-oc CPU which will probably be borderline irrelevant within two years for high-ultra performance in modern titles, be my guest.. Each one with his own considerations. Regarding i7, if you can pay for it, sure, but i5 is kind of a dumb choice in the long run considering the other options out there. 
 
I'll just put it here...
 

The beauty of reality is that you need money to buy things.

If you want longevity, I wouldn't do it on the stock. That's if you're chip can even hit 4.0 to begin with...
I see too many People that are too optimistic regarding that.
I have a 1600 that needs 1.38 for a fully stable 3.85ghz (I also run llc 3). To stabilize 3.9, only 50mhz more , i need 1.4-1.42...Oh, and I run a noctua u12s that runs on 100% all the time (to keep temps as low as possible ). With this settings I have great CPU temps under full load (62-66 stressing, lower 50's when gaming) and its fully stable. Im talking long runs of realbench stress test, IBT, prime95 and games. No crashes, no throttling (people seems to miss the latter). Many people are posting half assed work when It comes to actually testing for stability , so I would really take it with a grain of salt when someone says "oh yeah, my ryzen runs stable at 4.0 on 1.375v and with the wraith spire". No, it probably doesn't...
Booting and Running cinabench 10 times is not Stability. Running prime 95 for 2 hours is not stability. Running aida 64 is generally garbage for stressing (realbench and IBT crashed in minutes oc's that ran hours on Aida). Stability is running multiple prolonged stress tests and passing them flawleslly ,  stability is doing anything it can do at stock (regarding zero errors). If you oced your CPU and it gives you a minor throttle that won't happen at stock ,even though it didn't crash on a test, its not stable, period. 
3.8 is possible for most, 3.9 for some, probably needing an aftermarket cooler for the long run for good temps, and 4.0 which is fully stable and 24/7 operable, not so many chips... I really wouldn't shoot for 4.0 with the stock, wouldn't even think about it.. maybe besides for few runs of benching and that's it (if you can hit it to begin with). And this is from "real world" first hand experience. Yeah, you have good chips that can do 3.9-4.0 with good voltages (and many that can't, like mine ), but most chances are its gonna be high, at least 1.4-1.42 (on a decent chip) to be FULLY stable, and I personally wouldn't do it with the wraith spire for too long, if at all.
