I installed new 5800x3D chip in my ASUS TUF B550 Plus Wifi II motherboard and whenever I do cold boot M2_2 nvme drive is missing even in BIOS.When I boot trought BIOS to Windows - it's there and working.I was with 5600x and with 5600x it doesn't have this problems. I can use sata ports but I noticed that whenever I use sata port 1-2-3-4 when M2_2 slot is occupied - M2_2 is going missing and sata is available(yeah I know it's strange because my mobo disables only port 5_6 if M2_2 is occupied). This started happening when SAM was enabled and now it happens even if SAM is disabled. CPU is working fine
I tried everything , when I mean everything it's literally EVERYTHING.
1.Reinstall OS
2.CMOS clear
3.Reflashing BIOS
4.Reflashing older bios - not working asus doesn't let me flash old bios - ''this file is not propper bios''
5. Reasembling whole pc
6.took out the cmos for 15 minutes +
7.Checked the CPU for bented pins (none)
8.Installed chipset drivers
9.Reinstalled GPU drivers
10.swapping M2_2 drive with M1_1 drive (both drives work perfectly fine)
11.Firmware update for neither of my nvme drives are available and they are up do date
12.Tried to set manual BIOS settings for M2_1 and M2_2 PCIe lanes from Auto to manual 3 and 4 lanes
13.UEFI mode
14.CSM is disabled/enabled
15.Fast boot disabled/enabled
16.DIsabling all the PSU cables and pushing Power button for 60 seconds so the front UEFI controller got reseted.
17. ?
The CPU works with other motherboard and the motherboard works with another CPU ,what is this ?
