Any 16GB RAM that can do non-overclocked DDR-2400 JEDEC besides Kingston HyperX Fury HX424C15FB/16 ?

With the current system that I'm building, I don't want to run RAM in overclocked/XMP mode. I've heard it can potentially trigger undesirable (for me) side effects like permanent CPU turbo boosting and other heat/power implications that I don't want to deal with -- I don't want to do any overclocking at all with this system.

For example, the I7-7700K supports DDR4-2400 without overclocking. An example motherboard like the ASRock Z270 SuperCarrier can handle DDR4-2400 without overclocking. The Kingston HyperX Fury DDR-2400 16GB can do DDR4-2400 out of the box, without overclocking, as a standard JEDEC/PnP profile:

Has anyone come across any other RAM that can do DDR-2400 with its JEDEC profile, without overclocking?

Fair enough, I guess that Kingston RAM is a good choice for you then. I would question whether you really need the extra features like 4 more PCIe lanes from Z270 (that go through the PCH anyway, which has the same bandwidth to the CPU regardless of which chipset you go with). But obviously I don't know your use case, so it's up to you.

2) The I7-7700K is only about $35 more than the I7-7700 and provides a definite performance boost, while still remaining under 100W TDP. I don't see a compelling reason to downgrade to the non-K processor:

Don't forget the cost of the cooler. Also, that site appears to include overclocked results for the 7700k ("Best Bench" at 5.15 GHz). In terms of clock speeds, the 7700k is 7% faster for single...

Well, I'd just prefer not having to deal with a situation like this:

http://www.overclock.net/t/1603927/xmp-enabled-on-gigabyte-gaming-7-overclocks-cpu

I've seen other posts of this kind of thing happening (and worse) with other motherboards as well.

With this system, I've spec'ed out the be quiet Pure Rock Slim as the CPU cooler. I chose it because it's particularly light and quiet, and can handle 120W TDP. The i7-7700K's TDP is 91W, which should be ample margin. What I don't want is to have the CPU be unpredictably overclocked unbeknownst to me, or even running at its turbo boost speed all the time. Rather, I very much want to take advantage of the 7700K's stock capability to handle DDR4-2400, which is presumably within its 91W TDP.

I don't mind going with the Kingston HyperX Fury RAM if it's the only one out there that meets this requirement. Just wanted to cast out and see if there might be other options that I'm missing.

1) Among other factors, I want Thunderbolt 3 capability, and haven't seen any non-Z270 boards that have Thunderbolt 3 support. Also the Z270 boards have more ports and PCI lanes which I prefer having. I don't mind paying more in this case if I can optimize my other considerations.

2) The I7-7700K is only about $35 more than the I7-7700 and provides a definite performance boost, while still remaining under 100W TDP. I don't see a compelling reason to downgrade to the non-K processor:

Again, I'm fine with the Kingston HyperX Fury if that's the only RAM that meets these requirements.

Don't forget the cost of the cooler. Also, that site appears to include overclocked results for the 7700k ("Best Bench" at 5.15 GHz). In terms of clock speeds, the 7700k is 7% faster for single threaded loads, 12.5% faster when turboing on 4 cores. So that would be the upper bound for the performance improvement you could see.

You probably have your reasons, it just seems like you have room to save a lot of money and still get 90+% of the performance.
