	Hello, I have a X670E Taichi with a 7950X. Since I got it, I noticed all sorts of instability, even when running with no OC (reset CMOS). At first I thought is was RAM issue, but now I don't think so. Initially I had 2x16GB Trident neo Z5 6000 RAM. I tried each stick separately in both slot B2 and B1 and still have the same stability issues (crashes in windows, segfaults in linux). Then I bought a second kit of the same type and tried with those, same issue. I am currently on BIOS 1.11.CB08 after downgrading from the now removed 1.14. I have tried every 1.11.XX version though and see the same issue. The only way I can get my system stable is to go into BIOS and disable any and all settings related to ACPI C-States. There are several places to go, to disable definition of C-States, then I also disable Global C-State Control. With these settings I seem completely stable, however I should not have to resort to this... Just wondering what else I should try/test/suspect in my setup... Thanks.
