Hello and welcome! Glad you got TPM up and running, and new ideas on how to do things like physical TPM installation are always welcome! So let us see what can be done for overclocking you 1660V3. But let us start with this statement:
- I did all my TBU (Turbo Boost Unlock) testing on X99D3M4. It is a DDR3 board, so I used a 2666V3 CPU
- I did all my 1660V3 testing on ZX-99EV3. Before testing, I used Intel FITC and verified that the Management Engine is identical between X99D3M4 and ZX-99EV3
I can see from your post that you are capable with both hardware and software, so I think you can actually put together your own CPU overclocking BIOS
- Step 1: Download the BIOS files in this post
- Step 2: Download the Machinist X99-U9 BIOS from this post
- Step 3: Follow “Swapping regions with UEFITool 0.28.0” in the last part of the first post. Take the BIOS region from “X99-U9_with_CPU_OC.bin” and replace it in “D1_M2_B2_251005.bin”. Save as a new file and flash.
Regarding XMC flash chip: Recently I have also gotten CPU overclocking working with an updated Angxun BIOS (X99-DS4). But basically I am hoping that there will be an updated Huananzhi BD4 BIOS with XMC flash support soon. It really is the best BIOS there is.
