Intel XTU and ThrottleStop no longer working to undervolt Xeon E-2186m after firmware update

hello, i'm still stuck, i'm at bios 1.13 dell g7 7790, i can slide all the sliders, i'm compliant with everything asked on this thread...moved files over etc...rolled back bios to 1.09, then upgraded to 1.11,12,13...
--
each upgrade my cpu can't go over 4.1...i'mma 4.5ghz. please HALP! i can't ever get past the 4.0/4.1 lies!

 

You know that ALL CORE MAX clock of the 9750H is in fact 4.0Ghz, or 398x-399xMhz due to BCLK not being exactly 100Mhz.

4.5Ghz is for SINGLE CORE load, ONLY.

 

Exactly. That is normal and cannot be circumvented. 9750H is a limited consumer CPU that is mundane by design.

 

when i buy a newer laptop, am i suposed to now keep this as gospel, that the adverstised "now with turbo boost 2.0 5.3 ghz..." is the single core load? how do i do the math to get it's norm max multi-core speed that i'm buying?

 

Either look at the documentation on Intel's web site or pay closer attention to reviews that are focused primarily on performance, with less attention given to aesthetics, proprietary features and gimmicks. The latter are a dime per dozen and generally constitute an echo chamber.

 

Had to RMA my ZBK because it went bananas, updated the BIOS and now it won't revert below 1.05.04 (which is already locked) stating the system policy disabled BIOS Update, which isn't true as that option is not selected. Tried both through USB drive and Windows. Any ideas?
