I did not try without doing the CMOS battery unplug.

Without clearing CMOS and Bios, not work. I will try another day unplugging battery and CMOS, I have problems with one antenna connector, it is a pain to fix it on the wifi card

I finally got my hands on a GT75 with the 8750H, what would be a normal stable overclock for such a system when it often will run on 6 cores? Stability is key for me so I only ever overclocked the 6820HK in my GT72 to 3.8 GHz with a -100mV undervolt and I have been very happy with that. ,
Is it necessary to do anything in the bios of the GT75 except to unlock it when the goal is a more moderate overclock? -
-
I have to admit that it did not even occur to me that MSI would sell their top of the line gaming notebook without any overclocking ability. I guess I cannot complain as I got it at a pretty good price and my Clevo P870DM-G cannot easily be upgraded to a 6-core processor like I wanted. Still it is really silly for their top of the line gaming laptop and given the fact that one cannot upgrade the CPU to one that can be overclocked. -
I'm assuming a lot of this stuff is fully applicable to the 9 series 8 core versions too?
-
It's not MSI's thing, it's Intel that decides that processors like the 8750H can not overclock.

And as I really got a good price I certainly won't complain or feel cheated out of anything, still very happy with my purchase that has 6 cores and each one is faster than the 4 cores of my overclocked GT72 -

- 1 core = 13%
- 2 cores = 25%
- 3 cores = 38%
- 4 cores = 50%
- 5 cores = 63%
- 6 cores = 75%
- 7 cores = 88%
- 8 cores = 100%

Chapter 3 and 6 updated.
Added % for the number of cores allowed to park / maximum unparked cores. -
Great work Hackness, have you made any tests as to how much you are able to extend useful battery life with this?
I guess not that much when you also have a power hungry graphics card but I would imagine that it could make a big difference in laptops with a GPU switch. -
I can confirm that on the GE75 9SF with the 8 core, Set CPU Flex Ratio Override to Enabled Set CPU Flex Ratio Settings to 8 cannot be done. You can set the override to enabled but the ratio cannot be changed. No matter what you do it will always stay at 23. This is with the latest BIOS.

But when you test by benching the cpu under battery mode, take control of the maximum allowed unparked core does make a difference to the TDP.1610ftw likes this. -

Can someone confirm 9th series BIOS UNLOCK code has been changed/disabled in New MSI 9th series CPU?

Hi i have a GT 63 8RF
i followed the guide until the ram thing
Should i have enable in throttlestop "clock modulation" & "Set Multiplier" Enable ?
And when it comes to the step " Chapter 2: Test if CMOS clear resets the RAM timings" when i follow these steps my bios just come back to default every time -

Thank you for the tips and this guide hackness. With your guide I have a really good improvement on my battery life on my GS63 8RE (4.7 / 5h instead of 3.5h).
I have a little doubt. Is there a way to show to the OS (Windows 10 1903 in my case) the actual clock of the processor? Some programs drop constant warning caused by the "low" clock of the processor, which taskmanager report at 0.8 GHz, instead of the real 3.8GHz on AC. All the percentage of CPU usage reported by task manager (general use and process use) are completely messed up. I would like to see the working again. Is anything that I can do? Thank you in advance -

Hi, i am new here, and i need some help or advice, i try to read some about throttlestop and undervolting. But i am new it this. Please help, i have MSI GT73VR i7 7820, with 1070, and not really long time ago its seems like Dragon Center dont do hes job any more. When you shifting power options its dont look like something realy change, just temperature seems like, but not performance... Can some body help with that? Sorry i'm not in the right topic

Hi guys, thanks everyone for very useful information. I managed to stop my CPU from throttling with the IMON parameters and also overclocked my RAM to 3460MHz. However it would be great if someone can give me tips on how to unlock multiplier control in TS as it is possible to change it but it doesn't change anything. Clock stays the same at 3.9GHz. another thing is how to change fan curve from the BIOS. I found fan section there and played with it but it doesn't seem to have any effect after all.

8700HQ? You mean 8750H. I want to go down with multiplier not up. I can get 2200MHz by disabling turbo but I want something between 3.9GHz and 2.2GHz.
-
Ignore the multiplier on the main front tab in TS.Last edited: Jul 31, 2019 -
Yes it is there but it doesn't do anything for me. You can set anything you like and it will still keep 3.9GHz. My laptop is MSI GP73 8RF

I have sorted it out. It wasn't working before I overclocked memory so I think it was about unlocking the overclocking menu in the BIOS. Now it works just fine. Thanks for help anyway!

Also i was not able to set Cpu flex ratio to 8, no matter what i write it keeps going back to 22. When i try 4965 it says invalid. But 8 does not apply?Last edited: Aug 7, 2019 -
All the modules are different it doesn't mean that you can't because someone else couldn't. I have Samsungs on 1.20V at 3458MHz and it works stable. It clearly worked. Look at the transfer rates. If you don't believe go back to defaults, run the tests OC and run it again.

To increase the read speed, increase the tREFI.
If you see BSOD or constant error, raise tRFC.
If you see freezing, lower the tREFI.
Stability Testing also requires about 2 full weeks of normal usage. -
-
Also I've been running @1.20V for about 1 month and more, it's stable on mine. -
I then tweaker voltages and found it was stable.

Back off a bit and see if it is still occurring. -
I am very aware that the 8750h cant be overclocked, but can someone explain to me how jayz2cents managed it on his laptop, here is the video.
