Thanks, I found an adaptor I had from 5.5x2.5 which fitted. I am using a 2200g, 16gb 3000mhz gskill ram.
Things I've noticed:
Turbo mode on cpu disabled by default
C6 mode disabled by default
Can set igpu frame buffer as high as you want (up to 16gb for me (set to 4gb)).
No settings in bios to allow any overclocking / undervolting of cpu or igpu
NO WAY TO SET RAM FREQUENCY (in bios)
Chipset seems incredibly hot to touch.
According to occt and HWmonitor, cpu idles at 2w and only uses 30w under load.
The power figures seem far too low, but might just be because turbo is disabled. It might also not be taking into account igpu. Lack of being able to set ram above 2400mhz seems very limiting. I'll see if ryzen master lets me.
