Currently, as far as I can tell, everything is cool and I want to keep it that way. I have a Phenom 2 X6 1100t Black Edition CPU, Asus Crosshair V Formula with 990FX chipset, and Windows 7 Ultimate 64-bit Service Pack 1. What I am curious about is how at risk is my CPU and what is the recommended course of action? Considering I hear that Microsoft updates are bricking installations and the firmware fixes cause significant performance loss.
Meltdown doesn't affect AMD. Microsoft has fixed their buggy Spectre updates and can now be downloaded and installed. BIOS updates will be released when and if the board manufacturer decides to release them.
