+NOTE: 6300 series CPUs have buggy microcode built-in, and libreboot recommends avoiding the updates. The 6200 series CPUs have more reliable microcode.
+Look at this errata datasheet: @uref{http://support.amd.com/TechDocs/48063_15h_Mod_00h-0Fh_Rev_Guide.pdf,http://support.amd.com/TechDocs/48063_15h_Mod_00h-0Fh_Rev_Guide.pdf}
+(see Errata 734 - this is what kills the 6300 series)
