You have to select "Sandybridge" as EVC Mode for your cluster.
The list within the GUI is sortet by the historical release date of the CPU which makes is easy if you have some Intel CPU knowledge. There was a big jump with the Nehalem 55xx CPUs followed by the Westmare which named 56xx. Than it starts with the E5- v0, v1, v2, v3, v4.
Enabling EVC during runtime is a easy job when you have Intel type CPUs as long as the newer CPU have the same or more CPU features. This isnt the case when you have partiell mitigate against Spectre,Meltdown and Co.
