If you can’t help me to find message with V4 bclk bootstrap method
Thank you
I've not had a v4 to play with otherwise I would certainly look into it. I have seen a couple of v4 pre-production CPU's reports show that BCLK strap should be supported, I don't know if it is so for production chips. People can check if MSR 0x61E is present which is required but do note that even if it is present it may still not work. For example the v3's report fixed CPU core voltage is supported but I've not seen it work, perhaps some secret Intel register bit needs to be set. From the sound of it, all has been tried with the full turbo on v4 and not working as v3. Can't say you didn't try.
Also I only have a single socket board so no hardware to test for multi-socket support. Good that some of other guys were able to do that. I did have some spare time a few weeks back where I hoped to try and provide a generic BIOS DXE FFS for voltage / turbo and other settings for up to 8 sockets with individual settings for each processor. It would have saved having hundreds of files for different values. Unfortunately I didn't get any response so nothing became of it. Not sure there's that many people wanting to do the mod anyway TBH.

Would someone with dual or more sockets and CPU's run a small program for me under the UEFI shell?
Thanks.
Edit: The free time I had over the weekend to provide up to 8 socket V3 voltage control from the BIOS with an FFS addon has gone now so no need for anyone to reply to this anymore.
Or maybe it's the way I went about it. I know I don't explain things very well but I didn't realize how bad it was until today. So I'm going to leave it to someone else and make this my last post. I've never been in the software or computer industry so pretty sure there's probably hundred's of thousands of people who can do this a lot better than myself. The EDK2 driver example should help explain about providing addon 3rd party BIOS setup support.
Non-K Skylake Overclocking
but they do not cheat TDP nor delete ucode.
Well they do cheat really because the power management is never initialized which means no power readings, DTS temperature readings, idle C-States other than CC1, no AVX and they cannot use later ucodes. Also this type of bclk overclocking is different from v3 and v4 as it is not linked to PCIe clock. Might be able to do something with an i5-8400 but for Haswell and Broadwell it's a no go, only the straps are an option.
