July update: I replaced the RAM, twice - some Corsair Vengeance LPX 3200 didn't work about 2133, but the Trident Z are running at rated speeds, albeit they need manually set in the BIOS. Lesson appears to be, as others have found, that Samsung B-die RAM is your best bet, and that a lower CAS latency is more likely to play nicely with Ryzen!
I'll post more photos shortly. I'm really happy with the box - although getting the LED strips to stick is still nearly impossible...
I've been waiting to build this for ages - have had the InWin 901 case for 18 months, and finally got the motherboard a week ago. Building it was - interesting. If you're using a large cooler, as I have, my main advice would be to plug everything you possibly can in first and put the CPU / cooler in last.
Now...RAM. Ryzen's issues with RAM are notorious - and this is no exception. With two sticks in, it freezes reliably before you can do anything in an OS. Windows 10 wouldn't install with both slots in use - but installed ok with one stick. Ubuntu won't install at all, and freezes on trying to run from a USB. I think this is a RAM issue, but it's also been suggested on google it might be an issue with the SSD - I will update as and when I can test. Worth saying it also freezes infrequently every few hours with one stick in.
On the upside, although it's currently almost unusable, the RGB lighting works a treat!
Things I have tried to render it usable: (1) Updating bios (2) Updating SSD firmware (3) Running memtest86 (9 passes, no errors found) (4) Setting the RAM timings to be really slow (5) Interminable fiddling in the bios
Any advice gratefully received...
