awful experiences with ASUS WRX90E-SAGE SE

[simwhiz64]

any of y'all running into issues with ASUS's WRX90E-SAGE SE mobo? i just built a new pc, and i've had nothing but problems, slow-downs, and extremely low (0.5GHz) clockspeeds with my wrx90e.

 

windows 11

amd threadripper pro 7965wx

kingston fury ram (256gb)

asus rog thor platinum 1200w psu

 

i do a lot of CAD/CFD sim work, and every couple of hours, all my cores go from 4.2 GHz to 0.5 GHz and stay there. task manager, my desktop, everything... it all turns into a 1 fps slideshow or takes forever to open/load.

 

a job that was supposed to take ~80sec yesterday took over an hour! when i checked, all cores were stuck at 545MHz again.

 

thermal throttling doesn't seem to be a problem either: the CPU never gets higher than 82-88*C under max load at 4.2GHz, but yet i've seen my CPU drop all cores down to 545 MHz even when i'm just browsing the web and core temps are 37-40*C.

 

i've spent all week troubleshooting and a friend recommended posting here for help. i'm starting to regret buying this thing. feels like ASUS made a crappy motherboard.
