Discussing 11980hk overclocking tips and seeking advice is valuable.
I'm currently dealing with some pretty unusual and fascinating hardware. Essentially, I'm working on an ES of a 11980hk running on a M-ATX board. I'm trying to push the chip to its maximum performance, but I've run into a few issues during the process. Under all core workloads, the chip is reaching current limits around 110W, and it's refusing to exceed the XTU and Throttle stop thresholds. P95 SFFTS temperatures stay below 75°C despite these efforts. I've experimented with BIOS settings but haven't found any options to increase draw. The BIOS is quite old, yet it still functions well for overclocking. Any advice would be greatly appreciated.

It's near the 11900k range but often performs better with around 6.5k threads. A Portuguese YouTuber conducted thorough testing and overclocking, and he didn’t face the same throttling problems I do.
it's orginally a mobile chip the TDP in spec is not the real value at all. in different laptops its configurable and here mounted on a desktop motherboard they clearly set it much higher than that. however to answer OP the manufacturer making this Frankenstein combination job can't remove the boundaries that intel sets for the min and max of every setting. If intel sold the chip as configurable between 25 to 65W in laptops and set max 110W in turbo duration the best the bios can do usually is infinite turbo. unlike a GPU that has controllers and sensing shunt resistors externally on the board you don't have anything you can easily spoof to make it get more juice than it thinks it's getting.
Leave Intel XTU before applying ThrottleStop. Within the ThrottleStop TPL window, attempt to set Power Limit 4 to zero. If this doesn't resolve the EDP throttling, you may have no further choices.
This outcome didn't seem promising, could C-states be responsible? It might relate to a C-state problem or an overridden VRM limit by the manufacturer. The Intel datasheet isn't helpful for Tiger Lake and doesn't give a clear maximum power figure. Edit: After some research on Hwinfo, I narrowed it down to CPU TDC specifically. Improved heatsinks and active cooling seem to work well. Anyone know how to adjust the TDC value beyond the BIOS settings?
I conducted further research last night and discovered the motherboard sets the CPU TDC to around 100A even though the limit is marked as unlimited. After pushing it to its limit, the CPU handled 160W smoothly. I’ll share findings once I’m back. There are a few minor problems now. The cores struggle to exceed 1.36V under stress, likely due to the adaptive voltage/frequency curve. My top core caps at 4.92 (100.5 BCLK), possibly reachable with a 50-70mV boost. Additionally, I’m facing issues with memory speeds beyond 3200, possibly because VCCSA isn’t detected in BIOS. While I can check voltages via XTU, those settings are needed for higher speeds to initialize. Would there be any way to adjust memory speeds and timings in Windows? I know ASUS Memtweak exists, but I don’t have access to it.
Throttle stop isn't suitable here because of missing per-core overclocking and voltage adjustments, which are essential for getting the most out of newer Intel processors (right now 4.7 on the weakest six cores at -20mV, 4.8 on the second best at -20, 4.9 with +40). It also aids in managing thermal output since the heat spreader isn't very effective and heat density is high. I’m using LM under the heat spreader but applying regular paste on top; I might experiment with moving LM to the top and increasing voltage from the BIOS. Memory/VCCS still poses a challenge for me.
