CPU:7900x
Motherboard: x299 FTW K
Bios: v.1.22

Hi,
I've tried to overclock CORE 0, per core.
Input Voltage: 1.850v
4.8ghz 1.213v NO Throttling (OCCT small data set 1Hour stable)
4.9ghz 1.275v Throttling
It drops by 100-200Mhz.

I figured out, anything set over 1.24v, starts throttling, doesn't matter if 4.8 or 4.9ghz.
The higher I set the voltage, the higher is the drop. 4.8ghz 1.35v, drop by 500mhz.

Temperature stays at 85 C max.

I've already disabled C-States and set Windows Power Plan from Balanced to High, but nothing changed.
Both EPS power cables, 8+8, are connected to the motherboard.

The Bios has no current limit and no LLC settings.

Any idea?

assuming you didn't goof setting things in your BIOS, your CPU will drop its clock speed if the CPU gets too hot, the VRM gets too hot, or if the current limit/duration is set incorrectly.

figure out which and fix it.

Intel i9 9900K Coffee Lake @ X8 5309mhz (+47.5%)
AMD FX-8320 Vishera @ X4 5022mhz (+43.5%)
Intel i5 4690K Haswell @ X4 5013mhz (+43.2%)
AMD X4 960T Zosma @ X6 4870mhz (+62.3%)
Intel i7 6700 Skylake @ X4 4709mhz (+38.5%)
Intel i5 6400 Skylake @ X4 4588mhz (+69.9%)

CPU temperature is at 85 C and VRM at 70 C Max, thats fine.

What is missing is LLC adjustments as well as any pre-configured multi-core enhancement. Neither are a big deal in the overall scheme of things, but they are certainly not there. Also notably missing is any sort of power limit adjustments. In many boards, there are power limits in place to keep the process functioning within its parameters and this can limit overclocking capabilities. A simple adjustment to those parameters and users are on their way.
