AMD Ryzen 2nd generation processors

Hi Martin,

I am waiting for the delivery of a few more parts so I can finish assembly (at the moment it is laid out on my workbench with cables all over the place).

The network driver is the one for that chipset from AOS 5.0.6.  Video is Panorama to drive a Samsung S24E650 monitor at 1920x1200.  Sound will have to wait for speakers and my ability to sort out which of the various sound sections actually work.

This board has real USB2, just not the actual connectors on the back plate

Connect a USB1/2 slot plate connectors or case connectors to the USB_3_4 or USB_5_6 headers on the motherboard, and you will have a working USB 2 slots that are hooked up to the AMD USB 2 implementation on the SOC, not the ASMedia USB 3.2 built into the B450. These are connectors 19 and 20 on the motherboard drawing, between the COM port header and the clear CMOS jumper.

Are you sure of that?  At the moment I have those headers connected to USB 2 ports on the case and a backplain strip and they require the XHCI USB 3 driver to work - I have not found a combination of USB 1.1 and 2 drivers that load and see them.

Disabled by default in the UEFI configuration I believe, it is a subfolder under the AMD CBS tab

ivan:
Thanks, as I said I have to do a lot more digging in the UEFI pages but that will be later when I have everything in a case and no fear of shorting something out.

ivan:
I have been looking around in the UEFI pages and there is no mention of USB 2.  There is only mention of USB 3 in there so I left it at 'auto'.

Maybe, maybe not.  The Mem output is similar to what I had with my first Ryzen processor before I started tweaking the mass of junk related to memory usage in the UEFI Bios, most of which is not documented.  Doing that I was able to get:
[C:\]mem -v

Total physical memory:      7,906 MB
Accessible to system:       3,311 MB
Additional (PAE) memory:    4,595 MB

Resident memory:              185 MB
Available virtual memory:   3,944 MB

Available process memory:
  Private low memory:         216 MB
  Private high memory:      2,240 MB
  Shared low memory:          152 MB
  Shared high memory:       2,178 MB

With the built in video and I expect I will get something like that with this 2nd gen processor which is supposed to have superior graphics.

With the B450 M S2H I'm running the memory does become available.
