Intel Core-i9-13900 or 14900 Stability Creo Parametric

a) Does anyone have experience with the stability and performance of Creo Parametric on an Intel Core-i9-13900 or 14900 CPU? 

b) what motherboard and chipset is advised?

c) There is also a chipset which supports ECC RAM memory.  Is it needed for a good stability of Creo ?

d) Is ECC RAM needed for a good stability of Creo Simulation Live ?

e) How is the sound level? Is it silent or a lot of noise when high performanceis asked?

f) How is the experience with over clocking the CPU to about 5.8 GHz regarding above questions? 

g) Comparing the specification with Xeon processors the Core i9-13900 may perform better.

- Is this also the case in practice?

- Is this also the case when not using the over clocking?

h) Is Creo always using the Performance Cores of these CPU and how is this managed?

i) How reliable is the Core i9 and what about lifetime when over clocking with respect to a Xeon processor?

j) Is over clocking possible or can this performance increase not be earned and is it downscaled by the workstation supplier (HP, Dell, Lenovo) due to thermal issues in the workstation housing?

Thanks for your replys
