I'd be surprised if it didn't function properly. Be aware there are some limitations with using the QVL to predict compatibility. The main issue is that the list isn't complete—missing your kit doesn't guarantee failure. The second concern is that the CPUs they reference use memory controllers in the top 1% of performance, meaning you'd need a very specific controller (which isn't likely relevant for your 6000 CL30). G.Skill maintains its own QVL, which tends to be more accurate and comprehensive. I'd prefer to rely on that source more, even though it's not perfect—my setup runs a combination not listed there, and it still works well.
Sure, no worries! It's totally normal to feel that way after a long break from building hardware. You're definitely more comfortable with software, but it's okay to take your time getting up to speed.
I used the Corsair website's RAM compatibility checker to verify my system's suitability for several projects. The key takeaway is to thoroughly investigate the hardware before installation.
I've been on that boat before a few times... That's why forums are useful.
The rear connections seem uniform. The onboard connections match as well, though the non-X doesn’t specify the audio codec and relies on Realtek for LAN instead of Intel. The X claims an 8-layer board with higher overclocked memory speeds, while the non-X mentions a 6-layer design. From what’s visible, the VRM ratings appear consistent, but any internal modifications remain unclear.
The main difference I'd care about is 8 layers vs. 6 layers. Without going into too much detail, more layers is more better (usually). The 6 layer boards have a tendency to have the PCB itself get rather warm under full load when running a 14700K/14900K without power limits, while that isn't an issue on the 8 layer boards due to their power plane's extra cross sectional area. The 8 layer board also has a better memory topology and therefore have an easier time running high frequency, but if you're just running DDR5 6000 at XMP, it doesn't matter as both will have no problem doing that sort of speed. If you already have the non-X shipped, I wouldn't worry about it. The main benefits of the -X is its better high speed memory support and better handling of no power limit i7/i9s, but since you're not running that high of a CPU speed and your going to running air cooling where you can't run it without power limits anyway (the NH-D15 can't handle a 14700K at 300W+), those benefits don't matter.
