But 8700Ks and 8086Ks should not have high package temp issues at 3200/14 XMP should they?
Nah, should be fine, really. It becomes more of an issue once you're pushing 3866/4000+, and even then, you should have cooling capable of making it a non-issue.
I was wanting to ask Dave when I move to a M11E board next month, will using (4) 3200/14 DIMMs increase my overall responsiveness/lower latency for the build, moving from only (2) 3200/14 DIMMs on the Apex 10 board?
When you start pushing memory benchmarks at the top-end, yeah 4 sticks is definitely faster than two with DDR4. This is well documented over on HWBot. As to newer platforms, perhaps unannounced platforms? I'm not sure. I haven't played with my samples yet enough, and I haven't played with many ASUS boards in quite some time. EVGA is starting to look REALLY REALLY good these days, and MSI is also shaking things up when it comes to memory. Like I said, I don't care too much about CPU speed any more... it is the number of cores, feeding those cores, cache and memory, that I like to spend my time playing with (which has really been the case since day one with me, yet when I got into this CPU performance was a bit lacking, and these days 5 GHz is pretty darn common.)
Anyway, you really want to make sure you buy a 4-stick set and not try to mix kits... Team Group has some 3200/C14 sticks inbound soon, so G.Skill is no longer the only option. The whole reason W1zz had 3200 MHz C14 G.Skill sticks to do that memory performance review was because I sent him that G.Skill kit (and helped arrange samples from Intel). Black Haru will have future board and memory reviews covered (I've stepped back from reviews for a while and am looking at other things here @ TPU) and he's expecting a set of those Team Group sticks to go along with a platform that isn't in the public domain yet. Keep your eyes on the front page.
I am sure i have to blame my cooler
I'm not seeing you pulling 150W+ on that chip in your screenshots, so I'm not at all surprised that you are having issues seeing what I am telling you. When you pull that 150W, you're really at the limits of what the stock Intel paste-TIM can handle with most cooling, so any added heat from anything immediately becomes evident. Delidded CPUs can handle more (sometimes 225W or so), and if you aren't at the limits of what the TIM can handle, you'll not see these temperature increases that much. That's what it takes to see what's really going on. If your cooling is more than adequate for your clocks, you'll not run into thermal issues, but when you're at the edge of what your cooling can provide, you really need to spend time optimizing voltages to get the ideal temps and avoid throttle or CPU damage. None of what you're showing here shows that, and then you're asking why you don't see what I'm saying... well no kidding. Yeah, you're doing it wrong. Most users are using very traditional cooling and have load temps well north of 80c, especially with a CPU overclock, and start running into issues with just 130W of power drawn.
I'll set up my soldered 8-core and see how that does with memory this weekend maybe.
