i would like to disable this but im not clear on the instructions. anyone able to walk me through disabling this and regaining my performance on my 9900x

EDIT: nvm got it added via an elevated cmd prompt. havent added to the registry this way so it took a little research for me to figure out where to copy the new registry code to so it would be added correctly.

Now. patches will come. I HOPE. ASUS deploy bios and mei on helpdesk

Speculative Execution – is the gift that just keeps on giving.

Do not worry Intel will release new microcode for your CPU platform as well. For all Skylake X SKUs we're now safe with 02000064 microcode.

9900K microcode for Intel TAA mitigation was 000000CA DATE 2019-10-03
