Hi,
The HT setting is in the BIOS... just look around. It is there.
Yes. With the original BIOS settings and mainly the original VRM hardware, the i9 9900k suffers from a bottleneck. The VRM.
There is only one HighSide-FET on the board. - I fixed that by soldering a second identical one to the 3 places on the mainboard.- Temperatures of VRM... it gets hot when at max. (default 79A) - I used copper heat sinks relaxing that issue a bit. And an additional low-profile blower fan connected to the PCH - Fan helps.
- There are many unpopulated capacitors on the bottom side of the CPU socket. - I used all cemaric capacitors of identical defective board and soldered them on my board.
- In addition I soldered 3 identical of that electrolytic capacitors to the cpu voltage rail. - THAT does the trick mainly. With this I am able to sink around 111A without thermal throttling of the VRM!!!
To drive that high currents I use ThrottleStop. There you see in the settings the Imax of 79A. I set mine to 120A.
All these modifications killed that bottleneck.
