Hi,
add the microcode to your bootloader's config! Below are two examples.
The first one is for grub2 and the second is for syslinux.
• rocketmouse@archlinux ~
$ grep "Arch Linux threadirqs" /boot/grub/grub.cfg -A4
menuentry " Arch Linux threadirqs" {
search --no-floppy --set=root --label m1.archlinux
linux /boot/vmlinuz-linux root=/dev/disk/by-label/m1.archlinux ro threadirqs ibt=off ipv6.disable=1
initrd /boot/intel-ucode.img /boot/initramfs-linux.img
}
• rocketmouse@archlinux ~
$ grep "Arch Linux ^threadirqs" /boot/syslinux/syslinux.cfg -A3
MENU LABEL Arch Linux ^threadirqs
LINUX ../vmlinuz-linux
APPEND root=LABEL=s3.archlinux ro threadirqs
INITRD ../intel-ucode.img,../initramfs-linux.img
The interesting parts are the lines initrd and INITRD.
I edit my grub.cfg manually, hence I can't tell you how to edit the
config to auto-generate grub.cfg.
Don't forget to install the microcode package first.

Please, if you have such basic questions, consider to take a look at the
Arch Wiki first.
