I'm sure it's coming. They couldn't hit 3200 at first either and now they can.all the cores are useless if you can only use 16gb of RAM.
Really wanted to get A new Ryzen rig for VMs ect ect .. but from what I have read on the RAM support just nixes what I want to do.
It's all to new to expect perfection. If AMD already sold a buttload of CPU's and could have taken longer it would have been better. They need money though and it's good enough for people to see what it's capable of. And you can run more RAM, just not as fast.
Just enjoy the positives and know that it's going to get even better.
