Why do I need to do more research?
https://www.tomshardware.com/reviews/amd-radeon-rx-560-4gb,5254-14.html
Because there are actual circumstances where an RX560 can exceed the PCIe spec of 75 watts. Yes, AMD and MSI list this as a 60-watt card, but TomsHardware did some actual testing.
Everyone on MR, and in my experience especially on the cMP thread, wants to help extend the useful like of some great computing platforms. There is an unbelievable amount of knowledge here, without which my cMP wouldn't be nearly as capable as it is today. The knowledge comes from insight, intellect, and experimentation. That is, an investment in time on their part to build up the collective knowledge. I, for one, am grateful - especially since it costs me nothing except my time to read it.
I also try and be cognizant of the fact that this is a global community, and as the saying goes, "some is lost in translation." Again, I am grateful that the default language for MR is English, otherwise it would have just a fraction of the benefit for me. I really don't know how those contributors whose first language is not English do this, but I am grateful they make the effort. My cMP is better than new because of contributions from people around the world.
In my years on this site, I've come to learn that it's helpful, at least for me, to try and understand where people are coming from. I really do believe that most here want to help. One way to help determine this is to go more "in-depth" on a user's post, and see what else they're like. For example, people with dual-processor cMPs may be interested in
@MIKX 's work on how to properly cool both CPUs. It's a good series of posts.
Anyway, best of luck on your cMP journey.
