@GtiJason What I posted about Flashback not updating the microcode was on a z590 Apex. It may work on z490, I have a z490 Apex but never paid attention. I just happened to notice it with the z590 Apex. Unless someone else posted about z490 not updating the microcode using Flashback then disregard what I said
Edit I just tested using Flashback on z490 Apex and it does update the microcode. I was on 2103 MC E2 and used Flashback with bios 403 and it changed MC to E0. So maybe it is just a bug with z590 Apex or it may depend if 11 gen CPU is installed. I currently have 10700k in z490 Apex.
When I had the issue in z590 Apex and Flashback not updating the MC I had 11900k installed. I am not going to remove the 11900k to test with 10700k in the z590 Asus can figure it out if they want.
