Opinions about my undervolting i9-14900k

I've done alot undervolt overclock settings, and i think the best balance I found is this to avoid thermal throttling and to keep temp under 90c.

I have this pc configuration:
Intel i9 14900k
MB Gigabyte Z790 EAGLE
PSU 850W Gigabyte P850GM Real Power 80Plus Gold 120mm
Cooler Liquid Deepcool LE360 V2 ARGB
RTX 5060ti 16GB
RAM Kingston 32GB 6000mhz

Here are my bios settings:

Pcore 49
Ecore 40
PL 1 - 220W
Pl 2 - 253
Vcore Voltage Mode Adaptive
Vcore Offset -0.060
LLC - High
TVB Enabled

I get consistent 4900mhz on pcore, which i think is important for my 4k work in premiere. And temps are always bellow 90c. no thermal throttling. My cinebench R23 score is: 36.430

Am i using the max that I can get from this cpu with my cooling/motherboard and psu? Or I can go above 50 on pcore somehow.
