Which microcode is suitable for Lenovo G50-30 - Intel N3530?

Question

Hello! I am using Funtoo and want know more about Linux architecture and security.

During Funtoo Installation process the `boot-update` command said me 'detected intel, check for sys-firmware/intel-microcode'. I have a question about what does my hardware really need. I followed commands from here https://www.funtoo.org/Microcode  , after installation o iucode_tool I have this:

# /usr/sbin/iucode_tool -tb -lS /lib/firmware/intel-ucode/*
/usr/sbin/iucode_tool: system has processor(s) with signature 0x00030678

Please. Do I need to emerge intel-microcode, and how to configure kernel?
