Z790 PG Lightning/D4 Cinebench R23 performance

Hello!

I have the ASrock Z790 PG Lightning/D4 Mainboard with an i7 13700k and 32GB(2x16) 3600mhz CL18 RAM from Corsair

The BIOS has the following settings changed:

Activated XMP1 Profile
Set Cooler Type to 360-420mm AIO
Set CPU_FAN2 to Performance Mode

This sets a Power Limit of 265W

In Cinebench R23 Multicore I get around 29500 Points and around 2050 Points for Single core.

Many reviewers get around 30500 or up to 31000 in Multicore.

Any Idea why I might be short of the last 500-1000points?

The arctic liquid freezer II 360 AIO has the CPU at 90-93C during the Benchmark.

I tried raising the power limit to 350W but I got no change in score.

According to HWinfo64 the max Wattage is 285 and then no warnings are triggered.

with 265W there is a limit exceeded triggered but the score is the same anyway.

Am I missing a setting I could try? Windows powerplan to best performance did not help.

Or would I need higher end Board?

Anyway, for the i7-13700K and the i9-13900K probably a Taichi motherboard would be better.
