Thank you! It is a really n00b move to get this wrong, but there is no pin count that I could find even in the motherboard manual, so without the tribal knowledge of RAM size I was on the path to getting it wrong. Funny how something that is literally plug and play does not have this spelled out more explicitly for first timers. I build robots daily, so I expect more ambiguity there, but this RAM issue caught me off guard.
@inarush I see that you use the RX580 GPU. Would you recommend that over the nvidia GTX 1060 speced in this build? I see that they have still not released the Mojave drivers and thought I should not support that kind of behavior and avoid the hassle. My card is still in the shrink wrap so I still have time to save myself some trouble for this build for a graphics designer (my wife).
Any advice is appreciated, thanks!
