Family=6, Model=3A applies to all of the 3rd Generation Core i CPUs.
I examined those among the machines I have, and got the results as:

x86intel[] table in /sys/src/9/pc/devarch.c, like:
x86intel[]=
{
----
/*      {6, 0x3A, 16, "Core i7"},       */
        { 6,    0x3A,   16,     "3rd Gen Core i-3/5/7", },
        { 6,    0x3C,   16,     "4th Gen Core i-5", },
        { 6,    0x5E,   16,     "6th Gen Core i-5"},
---
}
Above lines works fine on my machines.

Hoever, we have a line of
        { 6,    -1,     16,     "P6", },
below those lines, so we may not need the above 4 lines.
