i7 13700k - clock speed 5.7GHz, turbo 1.55V
The VID is set into the chip for stock clocks and their voltages, with vcore reflecting what the CPU actually receives. Over many Intel systems this has stayed consistent. The example here shows how long it’s been... this is just one case. My X5690 had a VID range up to 1.35V, which matched the board’s maximum clock voltage. At that level I achieved around 4200MHz and ran the clock at standard voltages.
Checked your voltage underload. 1.55 could run smoothly with significant droop down to 1.4v.
I can now operate smoothly at 5.4Ghz turbo with C-states active. I’ll test all P-core OC up to 5.5Ghz to understand performance. When c-states are off, stable operation isn’t possible below 1.36V. Running cinebench shows identical results but at lower voltages. How can this happen?
