Undervolting CPU Core and Cache with Different Value

I have an i7-9750h and recently read that when undervolting you need to set the amount of mV of the core and cache to the same value. I have the core set to -150mV and cache -125mV and it's stable, however when I set both to -150mV it crashed and I reverted back to the first setting. I'm using ThrottleStop and HWInfo for monitoring the voltages.

1) Should I just keep the first stable value or should I lower the core voltage to -125mV matching the cache value?
2) What happens if the core and cache voltage not in the same value/voltage? Does the undervolt still works?

For additional info: I searched that Core and Cache shares the same voltage and in order for undervolt to make difference.

A quick search of 9750H brings up multiple threads, read this one first.
