@Lost_N_BIOS Thank you! I also wish you a Merry Christmas and all the best wishes for the New Year! According to the BIOS in Intel ICC section, an acceptable range for the Spread Percentage is <0; 50>, where 0 = 0.00 % and 50 = 0.5%. I am pretty sure that something is wrong with ME FW, therefore I will not touch these settings anymore :D I was pretty sure that I bricked the laptop and this is not the best felling ;) As I have locked 9750H the only thing I could really play with was the RAM settings and I think I found the sweet spot already. Using throttlestop, I could also achieve -0.12V offset on Core and Uncore. As for RTX 2080 which is in this laptop, the default vBIOS was 150W. I have overwritten this vBIOS with the one from ASUS that is 200W. Power supply is 330W, so it is still fine, even after increasing the L1 and L2 power limits for the CPU. This additional 50W gives tremendous OC capabilities, taking me far away on the first place in the 3DMark for all the benchmarks (within the same CPU+GPU people group). Now I am looking for best GPU undervolt/performance ratio and this will be the end of the OC ride :)

Cheers and all the best!

@7empe - Then update ME FW if you think it might be bugged ME FW. I'd suspect more the BIOS, either on purpose, or just by poor coding, since this is supposed to be hidden from you anyway, but it could be a hole type issue like I mentioned.
But yes, I know what you mean about "That feeling" it's caused by not having a set of $7 tools in your hand, order CH341A + SOIC8 test clip with cable now, then in a month or two you'll feel better about playing around
Careful on the undervolting, at least if doing on BIOS-side!! I'd save that until you had programmer in hand too. First place in 3DMark's, nice!!

Merry Christmas!!

Undervolting is done after boot sequence, so in Windows through the throttlestop app. My experience says "do not ever touch boot-time voltages in laptop's BIOS" ;) Next step is to order the programmer for sure :) I will feel much more comfortable.

Merry Christmas! :)

Sounds like the best way! Yes, programmer is so cheap, everyone should have a set for sure
I have a few, some cheap, some expensive, so I'm always ready to fix any type of BIOS!

@FengXi
If you need it, please provide a BIOS dump made by BACKUP_Tools.
And also a copy of the variables. H20UVE_100.00.9.2.zip (run "GET VARS.bat" to get "vars.txt").
