When trying to run higher speeds you need to increase the SOC voltage to keep the IMC happy, 1.10V to 1.15V will probably work for 1800MHz (DDR4-3600).
I recommend not using XMP on those higher speed kit's and to set them manually instead.
This should probably work alright for b-die.
3600 @ CL14-14-14-14-34 tRC 40 1T w/ 1.5V VDIMM & Gear down mode: Enabled
If this works then you can of course reduce the VDIMM to a more comfortable level if you wish, though 1.5V is not going to hurt anything.
Alright, thanks for the help. I will try it out over the weekend when I have time and see if I get lucky and post the results. Thanks!
