Crappy VRMs on B350s, few X370s as well - inadvisable Ryzen 7 overclocking over 1.32-1.35V

There's a lot of brand bashing. MSI was once garbage, now they're much better and they learned, using better parts. EVGA in the late 90's-early 2000's was complete garbage. Now they're top tier. Gigabyte was fumbling for a few years 2009-2011 and had bad runs of mobo's, now they're better. Biostar has always been a budget build company, and unless you're overclocking, they wonderfully stable. Every company goes through growing/learning pains.

The z370 boards are OK, but if you consider just that generation showing they are all better now... I mean everything from p67-z270 generation boards have been a massive let down. There are videos on the web of the krait editions literally burning.

You see, the difference is does it happen at 60C or 120C

Had a Phenom II X4 980BE (125w) for years, overclocked to 4,2GHz, on a cheap 770 motherboard with 4 VRMs without heatsinks, temp. on them never reached past 70º, they only had normal air flow, that was enough.

Same with board in my sig, also 4 phases quite enough for light OC of Ivy Bridge i5 ... but that's 70C, thing would crap out often if it were 120C like with some boards that this thread is about.

Yeah, but why would any consumer be OK with having to do that to make product he or she bought viable for sustained loads?
I guess it's fine for web browsing, but for sustained loads excessive heat buildup around the vrm will make power delivery less clean and cpu can become unstable.

Sustained loads are not a problem. It's overclocking that causes the VRMs to get too hot. General consumers are not going to OC much. Anyone willing to dive into an OC will think nothing of adding aftermarket cooling.

I meant sustained load while overclocked obviously ... my point whole time, little more expensive components and even oc wouldn't make them hot, dammit
