This is impossible.
You would have to have a script to "automatically" change the Bios settings by booting to a flash disk to write to the proper register. This can only be done via a boot disk, and only SVET would know how to do such a thing.
In addition, such a script would NOT BE ABLE TO BE SHARED WITH ANYONE ELSE if it were done for YOU, or you could DESTROY Their bios. Because the offsets for the bios options change for each bios build that is released, that's why in the Paloesco thread, you have to follow instructions on how to find and disable Bios Lock (thankfully there is a fullproof way todo that without needing a GUID key which changes repeatedly, BUT the hex offset you get when you find it will STILL be SYSTEM SPECIFIC).
hell I don't even know if that's possible to automate that. If you're talking about a "Boot to EFI prompt and have a menu automatically change IA AC loadline and IA DC loadline to 1 via a prompt", only SVET could do that and he definitely won't do that for free.
Paloesco wrote a bios unlock thread which SHOULD work (UNTESTED !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!) for the GT75 Titan (provided you use amibcp 5.0.2 from tweakdown's driver page as 5.0.1 crashes and corrupts the APTIO capsule in the GT75 Titan), and then you can just unlock what you want, but again there's risk.
SVET unlocks everything. Everything.

Months were spent before trying to get this to work on the Asus G750, but there wasn't a good way to replace the lost air flow over the rest of the laptop components. The thread was cleaned out so others wouldn't take the idea and endanger their laptops.
I did inform you of this data the first time you tried it to help you understand the entire system issue, and what kind of risk it was long term to stop the airflow to the rest of the laptop.
We did talk with Asus at the time, and they said they tried the same things to get better air flow to the heat exchangers, but found that they didn't have a way to then get air flow over the rest of the laptop components and storage, so they abandoned the idea.
If a laptop maker would build in another heat-exchanger in the middle on the back of the laptop to pull air over the laptop from front to back and use air guides (air dam's) to isolate it from the GPU / CPU heat exchangers and their air draw through a point closer to their intakes, that could work, but without accounting for cooling the rest of the laptop components the holes in the case aren't a good idea.
After the HID warranty expires, I doubt MSI is going to want to support those laptops, unless HID works that out with MSI now on the front end.
Hopefully that's already happened.UncleMysh likes this. -

I completely broke the Intel Management Engine by doing something stupid like that in the unlocked Bios. Like I broke it so bad that the normal recovery options didn't work. Like, I broke it so bad that reflashing the bios didn't work. I broke it so bad that I couldn't even flash ANY version of the intel management engine to fix it. YES I could have used my Skypro programmer and FORCE Flashed the original Bios which would wipe EVERYTHING clean but then I would have lost ALL of my DMI system information.
Svet was able to fix it for me with his own confidential magic. And then the moderator at win-raid.com asked me to share the program SVET used to fix my intel management engine. I refused to share it.UncleMysh, Vistar Shook and Spartan@HIDevolution like this. -

I corrupted my Intel management engine by messing with hidden menus, and clearing CMOS and flashing the original MSI UEFI Bios did NOT fix it. Win-raid recovery instructions did not fix it. I basically bricked my ME. Only Svet was able to fix it.
Brother @Prema was not joking around.
@ryzeki gave me permission to give the bios unlock key to specific users in emergencies. But not to distribute it on forums.

If the changes are done in the OS, can be backed out easily, and aren't applied at boot until they are stable, that is a much better solution.
That's why the simple solution of changing 1 value, the CPU voltage offset, if adequate to end thermal throttling out of the box at 100% load is such a better solution than these proprietary BIOS solutions.
Really there is no need for all these hardware and BIOS hacks for 99% of the laptops and owners, so that's why I push back against making them the "standard" answer for thermal issues.
If you can't share the changes, then they aren't a useful solution. -

Hopefully when you undervolt for comparison you get similar results, if not as good at least good enough for "the rest of us". -
Edit. From a review... The load temperatures are a certainly on the hot side, however. The GTX 1080 GPU is fine at just 78C but the CPU temperature creeping towards 90C is more of a concern. The 4.28Ghz clock on the CPU doesn’t throttle back though, meaning performance doesn’t drop off. However, we even saw the CPU reach highs of 94C by looping Cinebench or gaming for an extended period.
With the GT75 having such a large body with plenty of cooling and powerful fans we would have expected better thermal performance. These high temperatures under load show that the cooling in this laptop isn’t quite good enough to make the most of the i9 processor’s overclocking ability.heliada, Vistar Shook and Spartan@HIDevolution like this. -
Undervolting works well enough to be enough. -
After you informed me, I informed you that the mod had no adverse affects on the temperatures of anything else subject to temperature degradation. The bottom cover is open enough to breathe well, but the idiots at MSI blocked the fans. Had they made the chassis thicker with enough space between the fans and cover to not impair air flow, the mod never would have been necessary. HIDevolution has nothing to worry about. They only people that need to worry about post-warranty failures are those using the machines without the engineering defects corrected. The ODMs don't need to care if their products function correctly as long as they last long enough for the warranty to expire.Ashtrix, UncleMysh, Vistar Shook and 2 others like this. -

Again, if you can replace the whole laptop air draw removed by the GPU / CPU heat-exchanger holes, by providing another air draw source - another heat-exchanger and exhaust fan to draw the air, then it is a good solution.
Simply short-circuiting the air flow and giving it all to the CPU and GPU heat-exchangers / exhaust fans isn't a complete solution.
Those CPU / GPU heat-pipes only go to the CPU / GPU and some related nearby components, leaving the rest of the laptop unprotected, uncooled, by removing the air flow that their cooling depended on. -
The 8950HK spreads the same 45w unlocked power draw over 6c/12t vs 4c/8t, and the MSI cooling with CPU undervolting, fan curve tuning, and application / game tuning will be the same situation.
No need for proprietary "secret" unshared BIOS settings. -
Think about it. What are you gaining by avoiding the mod? Nothing. What are you losing by doing the mod? Nothing. Garbage is garbage. You fix things the best you can and write off the loser brand that sold you a piece of trash and stop buying their broken junk.

Also undervolting is a dangerous option too. You undervolt in the stock bios too far low, you make a typo and try running your 8950HK at 500mv, hello brick. And if you don't know how to clear CMOS, hello, RMA.
One could argue that's why undervolting is "hidden".
Ok so with that argument, how come it's possible to put a stock voltage of 500mv STATIC OVERRIDE VOLTAGE in the stock Bios and then brick your laptop THAT Way too?
Then there's RAM timing fail bricks too
Bricks all over. Back to sleep I go..... -
Stopping Thermal Throttling, which is really the only goal needed - stop thermal throttling and you stop performance loss.
It worked fine on the 6820HK and 7820HK for many thousands of people for years successfully, and will continue to be a technique of choice to reduce thermals as long as the BIOS from the vendor brings hot CPU voltage.
There's no need to get more complicated. Especially if you don't have time to be sucked in to long drawn out hardware hacking - re-pasting, re-padding, cutting holes in the bottom case, all to redue thermals even further than needed.
It's a sport that most don't want to be involved in, so provide a simple solution, share the BIOS settings and provide a simple How to Step by Step, and stop hiding behind it being "too dangerous" as the reason to not share the settings.
Puh-lease spare us the subterfuge.
You are the one encouraging everyone to get unlocked BIOS and make similar changes for many months - all shared publicly, and now all of a sudden it's "too dangerous" to share?, we now have to buy a proprietary product as our only choice for the solution?

@hmscott you're still missing the point though.
Undervolting is needed NOT because of IA AC DC being set to 1.80 mOhms but because MSI is using vdroop compensation. Vdroop compensation is not some Intel designed feature. But we have NO way to turn that off. Vdroop compensation by itself isn't bad at all. Neither is IA AC DC =1.80 mohms BY ITSELF.
The problem is BOTH are working at the same time. That causes problems.
And undervolting isn't a perfect fix. Undervolting undervolts EVERYTHING, so you risk running into idle BSOD because that 650mv VID at 800 mhz at -100mv now becomes 550mv VID. Not just 1.25v becoming 1.15v at full load.
IA AC DC loadline does not have this problem. Because its based on resistance. The less power draw, the less voltage compensation. So changing this to "1" instead of 180 or 179 will NEVER cause an idle BSOD if load won't BSOD even sooner.
In an old post, you said that Intel chips are overvolted from the factory. But they are not overvolted. They are programmed with a DEFAULT VID for every multiplier step from x8 to max turbo multiplier.
Then, the IA AC DC loadline setting of 1.80 mOhms is supposed to REMOVE or PREVENT intel's own designed vdroop, that way the chip operates at the proper voltage. Example: if x39 on a 7820HK has a 1.2v default VID for adaptive voltage, you have intel designed vdroop, which will drop this to 1.1v at full load.. But this is unstable because the VID is 1.2v. So then IA AC DC loadline comes to the rescue, boosting the voltage back to 1.2v at full load.
And everyone is happy.
See?
The problem is MSI is using LOADLINE CALIBRATION ALSO, which does the (effectively) same thing!! Stopping vdroop.
Then.....you throw IA AC DC of 1.80 mOhms on TOP OF THAT......that 1.2v is now 1.3v at heavy load now! (1.35v with AVX/FMA3).
Now you see what I mean.
And you still have to answer this question:
How do you 'undervolt' or explain the logic in "undervolting" when a user wants to use static voltages ?
What if he wants to use 1.2v override voltage?
Then what?
You realize that RIGHT NOW, if any user put in 1.2v static voltage, that voltage is going to be 1.3v-1.34v at full load right?
So what do they do? "undervolt"? So now they need to put in 1.08v?raz8020, Vistar Shook and Spartan@HIDevolution like this. -
The bottom line is, laptops are junk and broken by design. They are not built by enthusiasts for enthusiasts no matter how fancy the LEDs and marketing lies about them are. If you want them to be something really special, you have to take matters into your own hands and start correcting severe mistakes. With few to no exceptions they fail to function as desired due to engineering incompetence and lack of regard for consumers. If you care more about the warranty than having a product that works and behaves the way you want it to, and do not want to get your hands dirty, then don't buy a laptop... or don't complain about it malfunctioning. Unfortunately, most gamer-boys don't know what kind of mess they are getting into because the marketing fluff is pretty crafty. Buying based on specs alone is the first in the list of many mistakes.

That's why the last test in undervolting is the "idle" test.
You start undervolting at -100mV, then adjust higher or lower undervolt setting to get the best undervolt under 100% load, find that stable setting by CPU stress tests, benchmarks, and finally real usage like gaming or video editing, or whatever you bought the laptop to do.
Then you set the laptop aside for 30 minutes, or whatever you can spare, and let the laptop downclock and drop voltage to the lowest level, and if it BSOD's or hangs, then reduce the undervolt by +5mV.
That's usually enough to get stable at idle as well as 100% load. If you want, make it +10mV and that way you can not go through another round of "idle" tests.
That method has worked for everyone. Everyone that has tried it has found their undervolt at -100mV dropped CPU temp by 10C at stock settings. And, they are done tuning and can go about their live's without spending hours, weeks, months modding their laptops.
Most people don't have time or a care to do further tweaking. And, that's cool, let them go, they are happy let them be happy.
Why force them to re-paste, re-pad, drill huge holes in their bottom case, and risk all of those physical operations just to get a few more degree's in cooling, especially since it doesn't give better performance, or longer life to the laptop.
As long as the undervolt gives you clean operation with out thermal throttling, you are done. If you can't get to that point with undervolting, return it and get another unit.
It's easy to undervolt, 100% load and Idle testing, and it takes far less time than it does to pull part the laptop and re-paste it, re-pad it, and cut up the case.
You can do the undervolting in less than an hour on the first day you get it, use it as a gating test to decide whether to keep the laptop in the first 24 hours, then you can go on with all the fun stuff.
And, don't forget to back up your OS image with the vendor supplied tool to create a 32GB USB 3.0 Recovery Flash drive. -

For people that ALREADY OWN The laptop and actually want to risk bricking by manually unlocking options via the already posted thread here:
You can :
1) donate to SVET and have him create the unlock for you safely, as he has been doing for years.
2) http://forum.notebookreview.com/thr...-clear-cmos-and-prevent-common-issues.812372/
If you follow Paloesco's instructions and manually unlock the bios menus yourself, after dumping your bios capsule with FPTW64 -d yourbiosname.rom -bios
(lets say you wanted to be safe and not unlock brickable options, in that case you would only unlock "Advanced" ->Power and Performance->CPU power management control->CPU VR settings, in AMIBCP 5.0.2 (5.0.1 works on GT73VR and GT75VR BUT NOT ON GT75 Titan--it WILL corrupt the bios capsule), what you can do manually is : set all menus leading up to that and the options you want to "Supervisor".
Go to Core IA Domain. (set this to supervisor too) as well as the options you want to access.
AC Loadline,
Set failsafe value to 1 and Optimal value to 1.
DC loadline, set failsafe value to 1 and optimal value to 1.
These will make sure that the settings remain defaulted like this after a full CMOS reset or Bios wipe (Bios wipe is holding down the power button for 45 second to do a full CMOS clear, e.g. after a RAM Timing change fail), although flashing a new version from the MSI website may revert everything to original.
then go to Overclocking Performance Menu and unlock everything and all submenus in there and set what you want to appear to supervisor. including the "Negative and positive" CPU Voltage offsets (you would not want to undervolt however if AC DC loadline is already set to 1--you WILL crash).
Then reflash the bios capsule with FPTW64 -f (yourbiosname.rom) -bios.
I M FREAKING WARNING YOU RIGHT NOW
I DONT HAVE A GT75
I DID NOT TEST THIS ON A GT75.
I DO NOT KNOW IF CREATING A BACKUP WITH FPTW64.EXE -D MYBIOSBACKUP.ROM -BIOS ,
unlocking menus to supervisor in AMIBCP 5.0.2,
changing bios lock from disabled to enabled to allow flashing the modded amibcp capsule in windows by using RU.exe on a flash disk,
and then reflashing with fptw64.exe -f mybiosbackup.rom -bios WILL WORK FOR YOUR GT75 OR IF IT WILL BRICK IT! I DO NOT KNOW!!!! THIS HAS ONLY BEEN TESTED ON A GT73VR WITH AMIBCP 5.0.1 (amibcp 5.0.2 is required for GT75; 5.0.1 will crash on menus).
I ONLY TESTED ON A GT73VR.
IF YOU DESTROY YOUR LAPTOP BECAUSE YOU CHOSE TO DO THIS INSTEAD OF DONATING TO SVET AND HAVING HIM DO IT, DONT RMA IT. BUY A NEW ONE.
(Fun fact: if you had been smart and invested in a SPI programmer, like a pomona 5250 soic8 clip, Skypro programmer and some male to to female jumper wires, you could recover from your brick and not have to RMA).
I told you what to do the "power users" way. Do not ask questions in this thread about this. Take it to Paloesco's thread. I will REFUSE To answer them here and i may refuse, at my own discretion, to answer there. If you were experienced enough to unlock your own menus without bricking, you would not be asking these questions here.
DO NOT UNDER ANY CIRCUMSTANCES, EVER, EVER, EVER, EVER, DOWNLOAD THE OFFICIAL MSI BIOS FROM THEIR WEBSITE AND RUN AMIBCP ON IT TO UNLOCK MENUS--EVER. (you can do this to 'see' what options are there, but you MUST use FPTW64 to create your own dump. (Courtesy of Dreamonic and Sirgeorge for this information).

@Mr. Fox
That can be solved if they set the IA AC DC loadline setting "Optimal" and "failsafe" values to 1 and then flash the modded capsule.
Notice they default to 179 (1.79 mOhms?).
Changing them to 1 and reflashing the modded bios capsule fixes that.
But I don't know if that's what they are going to do. I know nothing.
The problem occurs if someone updates their bios via MSI's website....

No it's not visible in the stock Bios.
If they FLASH the modded APTIO capsule like I showed: then:
If you reset CMOS, the value would DEFAULT back to 1, but only if HIDevolution FLASHES the modded value themselves.
Them setting the unlock combo and shipping the laptop out won't work. All it takes is someone to do a RAM Timing change fail or anything that forces a NVRAM Reset (like turning the power button on and keeping it pressed till it shut soff) to lose the setting.
Basically HIDevolution would have to edit this as shown and then flash the APTIO capsule back:
like this:
This way, it will default back to 1 on 'failsafe' defaults (assuming that a CMOS clear uses failsafe defaults). As well as optimal.
The problem is they would also have to disable BIOS LOCK just to flash it with FPTW64 as wellYou can't edit the official MSI downloaded bios ROM with AMIBCP because it will cause a brick. Other stuff like a copy (inactive) of the EC and ME are embedded there too and AMIBCP isn't made to handle that. But with the bios unlock key, you can just disable Bios lock directly, and then dump, edit and reflash the capsule. you don't even need to even have those settings unlocked for the user (and this method can be tested with a test system).

They aren't going to be given the BIOS unlock combo, and from what you and @Phoenix are saying they won't be given the information so they can set the settings themselves, so are they going to need to RMA the laptop back to the seller to restore the settings?"
