Question Asrock z390 Taichi: manual indicates setting that DNE

[80251]

In the Asrock z390 Taichi manual it states there is the following setting in the BIOS (UEFI?) settings:

'GT Core/Cache Voltage: Configure the voltage for the integrated GPU Core/Cache.'

The problem is there is no such setting. Is there really such a setting for Coffeelake CPUs as "GT core/cache voltage" and does the reference to cache voltage refer to the uncore/L3 cache of the CPU or some sort of cache in the onboard Intel® UHD Graphics 630?

What processor are you working with? What BIOS version are you currently on for your motherboard? The cache is for the CPU not the iGPU and you might want to look for it in BIOS as Ring Voltage.

There's no Ring Voltage setting either. VCCSA, VCCIO and Vcore are the only adjustable voltages that don't seem to have to do with PLL or Vtt. I'm running the latest BIOS for this motherboard: P4.30I.
