I test all 3 bios and the same result not more than 2.7ghz maxim at all core ,the cpu temp and energy and cpu temp see in bios and I disabled these two but without success the same results all core at maxim 2.7 gh

What about Power Management >> Dynamic CPU Frequency Mode << That is what this last set of files was about testing Disable that, check with SiSandra again for all three BIOS, do you get same warning as before about Dynamic Mode enabled?

I test all 3 bios with sisandra and shows the same problem dynamic frequency,and in bios on option syas that dynamic is disabled but is in greey doesn't have option to change that and says dynamic is disabled in greey

Thanks, and sorry about that, we don't want grayed out option, let me look at that again and make you need files. I think I made those changes to change the setting from 'Always Low" to "Disabled" as an option, but then forgot to make enabled/ungray for you!
I wanted you to be able to set dynamic and disable, so you could test if SiSandra says same for Dynamic and Disabled.

Also, if it's set to disabled now, that means original BIOS may have been set to "Always Low" as default, so even if new "Disabled" option fails, be sure to test setting "Dynamic" too, since I don't think that was the default setting now that you say "Disabled" shows as default (I didn't change default behavior/choice, only edited the setting in place)

Here is those same three BIOS again, this time you should be able to adjust. Test each BIOS and for each one, test both Dynamic and Disabled. If this fails, maybe we need to figure out how to make it "Always High" instead of disabled

Wait! I checked, all three should not be grayed out Show me image of this page, so I can see what else is gray and what is not, thanks

I think is my error when I explained ,I didn't explaind well,the option dynamic cpu frq mode is good but wwhen I click on him its says dynamic switch disabled In teroy should be disabled? but nothing change the sisandra shwos the same problem I will send you foto

Thanks! Yes, I didn't understand what you meant, but the images help. That should be two different options you can select, is it not? Options should be "Dynamic Switch" or "Disabled" Can you move between the two and select one or the other?
I do not know which you want, which is best. I am not sure what is originally the default value, maybe we need to first have you test unedited option (without "Disabled" added), only unhide option, so you can then see what default setting is.
Dynamic may be what you want, or disabled. If you cannot select disabled, in any of the three BIOS I sent you, then this change from "Always Low" option to my edited "Disabled' is a failed edit, I expected this since "Disabled" is not an original option for that setting.

I tried to find an "Always high" value to make that setting instead of "Always Low", but could not . We need to find BIOS with these setting, that has disabled option originally there as a choice, maybe that could help me do better edit for disabled but I'm not sure on that either.

All this time we're messing with this, you have Intel Speedstep and EIST disabled correct? Also, please add CPU-z main tab screenshot, thanks

Please also link me to other versions of your BIOS, I see here at Toshiba "Always High" should be an option!! So maybe only this BIOS it's missing, I will check all older ones you link
Or give me full model name, like PSK1WC-10F01S or L750-BT4N22 etc, seems there is more than one that use this same L750 model name.

Never mind, I think both those models I gave above are same, after selecting OS here all files are same for both (checking other BIOS now for "Always High" option) - I checked all versions (3.60, 3.50, 3.40, 3.30, 3.10, 1.40) none have "Always High" option

In windows power options, do you have set High Performance with AC ?

yes is set to high performance the motherboard of this laptop is DABLBDMB8E0 REV;E Satellite L750-1KU

Código: PSK2YE-0JY00CCE , all bios that you said is compatibile with this laptop model ,turbo is enabled because when I disable turbo wont get much than stock value 2.5ghz and with turbo enabled get 2.7ghz at full speed all core at maxim ,but when the processor when is not going on maxim is going one core at 3ghz 3.4 for 2 seconds and about dynamic swithch in the foto possible will be two option but wont let me chosee a option only appears like you see in foto

Turbo is not EIST and Speedstep, find and disable those in BIOS. 3.4 is nearly max for this CPU, I still think heat is what limits this under load.

Thanks for explain on Dynamic, that means my changed from Always Low to Disabled is a failed edit. We need to find BIOS with Always High option there, I can't find any from that one page I linked, those are all very old systems.

what i found in bios is P STATES IST ENABLE PROCESOR PERFORMANCE STATES when is disabled turbo wont working,and with another program in windows like ThrottleStop detect sped step but when i disable this speed step nothing happens or in bios this spped step has another name but with the same function because the ThrottleStop detect speed step I will sen you a foto and a short video to see better https://www.sendspace.com/file/rbclvd

P-states not what I mean either. Two things, one Intel Speedstep and other EIST (Enhanced Intel Speedstep), these in BIOS not in throttlestop. Leave C3 enabled, and maybe leave EIST enabled, for turbo...
But for now, all this moot point, since Dynamic CPU is enabled. Nothing is going to work until we can disable that or set Always High.

ok then means we cant do anything ?you have another solution?

I am trying to figure out how to change Always Low to Always High, but so far with blind changes (Guessing) I've not had any luck. I need BIOS from this company or at least an Insyde BIOS, that does include Always High as option, maybe you can find via Google (Dynamic Always High + Toshiba or Insyde)
Then once you are sure someone said it's in their BIOS, give me the model and I will look. I looked around earlier but wasn't able to find good assurance by anyone it was there, will keep looking though

I found a bios I will send to you its from another model https://www.sendspace.com/file/nt20r2

That one is same, only Dynamic switch or Always low

yes ,but this bios has some options that we are looking for a long time like powerxpress for intel gpu and muxing and something about turbo custom I will send you the dump and some fotos ,I installed this bios with programmer but wont but https://www.sendspace.com/file/9wgztv
