Hmmm, I am really don't understand.
HWiNFO say P/E cores for 7540U, but these cores have 7545U.

Ok, next questions.
1. Mode: Quad-Channel. Really? In docs say: "Memory Channels: 2" https://www.amd.com/en/product/13211
2. 2 Performance and 4 Efficiency cores. Phoenix 2? Some official documents about these informations? I found only, that "MCU A70F8x" are "Phoenix 2".
