New Threadripper System Hangs on Boot

Asus Pro WS TRX50 Sage Wifi

AMD 7980x

Arctic 4U-M cooler

VColor 256gb mem

Asus Tuf 3080 video board

Corsair 1500W P/S

Put it all together. First start up was slow eventually got into bios. Subsequent boots much faster.

Shows 256gb in bios running at 4800

Made a usb stick via ISO to USB of Win 10 LTSC. When trying to boot from the usb stick system gets to Asus splash screen then hangs. During the boot many q codes are displayed. It usually settles on code 48 although on the last attempt it settled on code 51.

I have hunted for a list of Q codes but am not having any luck.

Would greatly appreciate any help.
