about "p cache" and "e cache" undervolt

[IdrisK]

Are "P cache" and "E cache" short for Processor Cache and External Cache, respectively? And should the voltage scaling settings be synchronized with the CPU Core undervoltg?

P & E refers to the Performance cores and the Efficiency cores and the on chip cache that goes along with each of these cores.

The P & E voltages do not need to be synchronized with the main Core voltage and the P & E voltages do not need to be synchronized with each other.

I am not sure what CPU model you have. It looks like some sort of HX or K series CPU. There are other posts in this forum with offset voltage examples. Search Google for your CPU model..

Thank you for your reply, my CPU model is 13980hx, if it doesn't need to be synchronized, then there are many kinds of permutations and combinations, I'll be patient to find it.
