Hello,

this is regrading 13600K on ASRock Z790M PG Lightning/D4.

I tried to check how the system behaves with E-Cores turned off - responsivness increased under moderate load but there is strange effect (according to LibreHardwareMonitor):
- at idle time motherboard sets voltage on CPU package of around 1.35..1.4V and that makes power consumption of CPU package at around 25..30W at absolutely idle state.
- under heavy load CPU voltage gets lower to around 1.15 .. 1.2v.

This is strange - I expect it should be opposite: at idle time voltage is near 1.0V and under load - around 1.3V.

This happens with default BIOS setting (v11.02).

...

With both P-Core and E-Cores turned 'on' everything seems normal:
- at idle power consumption is below 10W and voltage is around 0.9V
- under heavy load - voltage is up to 1.4V with power up to 250W

I have the same MOBO, it is purely due to the P-Cores taking up all the extra work. Also, if you haven't done so, theres a BIOS update for our MOBO, v11.04.

For when you think you have enough, add some more
