hello, I just bought a Z690 tachyon. I have a problem adjusting my Vcore. In the bios the preview shows me 3.062 V (which is impossible, it's a bug). But the main problem is that I cannot modify my Vcore no matter what value I enter, it remains at around 1.15 (the stock Vcore I think). I see the same value on several software programs (cpuZ, HWmonitor....ect). I am on Bios X3I but I had the same problem with the latest official bios F28. I read the topic and I didn't find anyone experiencing this problem, is my card defective? THANKS
