I after replacing so many troubled Crosshair Hero VIII Motherboards X570 WIFI board, I got one working and since I am waiting for 3950x release by November, I am running 3200G. Everything was great with stock bios and I upgraded to (Version 1001 2019/09/25) it was a night mare. I got F9 0d and many error codes all related to ram. I had to pull out all 4 sticks of F4-3200C14D-16GTZ and finally got it working with one ram stick on B. I went in and reverted bios to Version 0803 and everything is BAU. But when I ran Corsair Link software, I notice Temp #5 running 98 to 99 all the time and it goes above 100c which i am really worried about. I am not sure what Temp#5 means and I don't see that in CPUID HWMonitor however, I was about to see it with older version of the same software.
