Question Help required with BIOS settings for an i7-13700k, such as undervolt and other options ?

[Infinix]

Hi, I have just got myself an i7-13700k and tried undervolting it, I only know about the offset voltage so I lowered it till the cpu was stable, Earlier it was fetching 1.48~1.5 volts, now around 1.3
Could you look at my bios settings and see if I need to change anything else from your experience? I am aiming for performance and efficiency (Don't want 100mhz at the cost of very high temps and wattage)

Build

• I7 13700k
• MSI Pro z790p wifi
• MSI Mag a850gl (It was in speculative A tier, but got a cybernetics platinum on efficiency and atx 3.1 cert so I think it is A tier)
• Gskill Ripjaws s5 16x2 36-36-36-96
• Deepcool ld 360mm AIO and Thermalright cpu bracket

The max freq on P and E respectively is 5.3 and 4.2 (Could I dial it higher?)
Cinabench scores on current settings: Single core- 2127, Multi core- 30,804 | Temps - avg 82, max 87

There are also some issues that I encountered:

1) I tried changing settings with intel XTU but whatever I do doesn't seem to have any effect (Disable Turbo-boost and 3.0 from bios but no effect)

2) The voltage only drops when I set it to offset mode, nothing seems to have any effect on the on the voltage otherwise

Thanks!
