[Guide] How to take full control of the i7-8750H (Advanced version)

Would you happen to know which version or at what date this change was implemented? Or do you think Svet will be able to do his magic on current version?

Svet might be able to do something able this.

But I remember the earlier BIOS of the GS65 doesn't have this problem, only the newer GS65 has.

You can also try flashing to an earlier version.

These are the GS65 9SE bios that's still available to download from MSI:

I was already on 10F, but it shipped with 10D so I tried a downgrade to 10C. Still no luck.

BITS seems to be a dead-end for troubleshooting this, and it's a real shame it hasn't been updated for newer CPUs.

I'll likely fire up a Linux USB later just to confirm the problem isn't exclusive to Windows. I'm running out of BIOS options to fiddle with and I'm still suspicious that it's an ACPI issue, though it seems absurd that this machine would ship with an 8-hour battery claim without working C-states.

Any other advice is quite welcome.

If you talk to Svet about that, please do post back. My 8SF won't accept changes to the flex ratio either (on any BIOS version) and it's kind of annoying.

 

I had a similar issue uninstalling IRST ( intel rapid storage technology) helped. Also, if I am on High Performance power plan in Windows C-state dont work for me.

 

I've got the SATA controller disabled in BIOS but forgot to remove IRST, so that's gone now. I totally forgot about Windows power plans too!

Still can't go deeper than C3, but at least that's two more variables eliminated.

-- Update --

Spent a bit of time fiddling around in Ubuntu (just tools like fwts and cpupower to check for obvious problems), lightning struck a tree on the other side of the world, and package states as deep as C8 started working in Windows. I do indeed need to be on Balanced or Power Saver to go deeper than C3. (Why MSI?)

Sounds like the whole issue was a fluke, made worse when I stopped thinking about which power plan I was on.

Thanks for the sanity checks folks!

 

Posted in wrong thread, but it works just as well.

Hi, thanks for the guide,
I managed to OC my stock 2666 19-19-19-42 to 3200 17-17-17-41. Could not pass 3200 so lowered the primary timings, so far it’s stable.

 

Hackness I have made the bios tweaks with 8750h and that imon 31999.

Strange that show me max watt draw 4watt at full load.that does mean 36watt? At benchmarks go good cine 15r 1250 and 20r 3040.

Undervolt with tweaked bios -90mv.

 

change in the bios 31999 to 21999 or 11999 (always put a negative : -21999 ) and restart, play a game or bench and see

 

Well I did. I tried 0 slope and 0 imon and show 60watt. Then again with -21999 and slope 50 I got 7watt. One more think it's strange still I can reach -150mv cache undervolt.and around 85mv core with tweaked bios

 

Guys it's there a way we do all cores work 4,1ghz? I saw some cinebench benchmarks and they hit around 1300+ at r15. A guy say 75 watt cpu .some other show that cpu 41 multicore.maybe any bios tweak?

Click the score for pics. Somes ppls cpu z show 41 multiplier.

Perhaps with modded BIOS, you could try contacting SVET on MSI forums and purchasing a fully unlocked BIOS.

You can then edit your BCLK to increase frequency. Or was it FCLK?

I see bus speed normaly.at that CPU z I dont thing u can touch bclk.

 

You cannot unless you get the modded BIOS, or at least that is what I was told when I inquired.

I noticed also that -31999, -21999 or -10000 with IMON Slope at 50 changes nothing.

 

Yea I tried now stock bios.just undervolted with throttlestop. It draw 60watt at full load till go to 45watt limit. Then I tried imon -11999 and slope 50 and max draw was 20watt.

Btw its anywhere tweak bios for false numbers for 150watt limit gpu?

 

I'm not sharp as @Falkentyne and @hackness , you should definitely ask them.

 

What exactly are you trying to do?

 

About gpu or cpu?what u mean?

 

And CPU-Z is correct in showing, thats just the maximum value that the multiplier can have, and the i7-8750H can run at 4.1GHz IF its only loading one core, all core turbo is 3.9Ghz and that is hardcoded either in the micro-code or laser fuses, the best you can do is a modded ME firmware that allows for BCLK OC and in a laptop with iGPU dont expect much more than going to 101Mhz, at an all core load, that means 101x39 = 3939Mhz instead of 3900, to achieve 4GHz you would need to have BCLK running at 103Mhz.

 

Do you have any walkthru for the Intel ME firmware edit? I'm on a RB17 Pro with Intel ME.

 

Well I found an issue with core parked.
If u have set the core parked at power plan 100% all cores works. If I lower this value let's say 80% or 0% then many cores its parked. And the issue it's that cores its parked cpu dont unparked them automatically when needed.If I do a benchmark or something it's still parked.works only if I unparked them manually.any idea?

 

Well something to registry though I fixed.it

 

Are your cores parked or unparked now?

 

For the 10th Gen GPU you'll need to mod the target power of the vbios using Mobile Pascal TDP Tweaker and do a hardware chip flash (Skypro with 1.8V converter with wire and clip, must have 1.8V converter, 3.3V will kill the vbios chip in 1 or 2 go) to bypass Pascal's software guard (falcon reset) or go to https://www.techpowerup.com/vgabios/ and search for the VBIOS that has the same device ID but higher TDP and flash using nvflash.

A good tip is that the vbios that has higher clock usually means the TDP is higher.

 

Now its parked but wakes up automatically.

 

Its 20th rtx2080.i really could mod this limit cause gpu runs so cool. 69 70 max

 

I believe Turing has some protection against cross flashing, what I heard was the core clock stuck at certain clock rate.

Regarding to the TDP limit mod, Turing cards are still not able to do, because the Falcon security on the Turing is no longer only limited to software verification, hardware is also included.

If you also want to achieve lower power limit with your current vbios, you'll need to play around with the voltage/frequency curve, first you'll need to set a target voltage in mind, lets say you do not want it to go above 0.8V, you can just drag and lower all points behind the 0.8V to the same position as 0.8V, that'll make the curve flat starting from 0.8V and your GPU will only go up to 0.8V at the corresponding frequency that the 0.8V will handle. This will immediately lower the highest temperature, but of course there'll be a performance hit.

 

Someone can confirm the settings at throttlestop for " cache iccmax" it's set to 11a?. Its unlocked ,but its strange that it set to 11amper only. That mean at bios have same settings.

 

Intresting.. does someone have try that settings? It's with uncore +130 and all other voltage default.its not mine but I thinking to try it. 3700mhz rams.
But I dont know why that guy did the benchmark at 37x multiplier. Instant of 41x

 

Wtf it's that maximum power test at prime95.lol
first time i tried today and my cpu stable at 100watt draw . Damn I dont wanna see this.
Haha

 

Hi any way to get 4095hz on i7-8750h. Even i did 41 all cores it does not achive 4095 and HT off.Do i get any benefits from it? I have unlocked bios by svet and if you have any good advice or tweaks for bios. Thanks

The cpu its locked not from bios.
Ur BCLK its grey out?
That bios have difference settings than unlock key combo?

 

Yes it diffrent then unlock key combo and i have bclk unlock but cant make it work for oc i can change the values but nothing happens. Can you show me your bclk settings pls?

 

My BCLK its locked. If u let u to change from 98,5 to 101 it not change the speed? The only way to overclock 8750h it's this. Hiw good it's this method dont know. But if u change ur BCLK by 2 u will get about 80mhz more to cpu speed.
What ur laptop model? Can u pick the BCLK page?

 

I need the enable ME state to see oc bclk percentage but rn it doesnt let me enable it. When i enable there are options on it as you said but default was 10000 to 45 spread. Even i change the values doesnt changed anything before dont know why. I need to bios reset for enable ME back gonna do it later.And what does whatcdog timer for bclk oc?

I have the Intel ICC menu unlocked on my RB17 Pro but any changes in that menu brick the laptop requiring a CMOS battery pull to reset. :/

How are you getting the settings to stick?

 

Disabled ME. As you said need cmos reset but can you get 100 bclk on your laptop? And what settings do you have can you show it pls?

Stock frequency
Well that svet bios let u overclock via BCLK?

 

Yes, up to 102Mhz works but with 102.2Mhz Windows doesn't boot.
It doesn't do much, I can do 1279 without it.

 

Strange.when I had ask svet for unlocked BCLK bios he didnt answer me. Which laptop u have?u use LM for that mhz or no needed?

 

GF72 8RE
Svet is the best, unlocked Bios and EC-Tuner to change the fan speed and LM!

 

I cannot oc it after changed values i got same values everytime i restart it.I coul do 10001 but spread lowers itself to 42.

https://imgur.com/a/Ii7iRMZ

 

Nope! Cant oc it more then 10040 and cant even oc it on bios. Somehow xtu overrided and let me upper some numbers.

All of you people are doing this wrong. And do NOT disable the ME--because if you are unlucky, you will NOT be able to re-enable it no matter what you try. And then the only person who can fix it is SVET. And do not overclock the BCLK (BCLK setting is in the primary "OC" menu at least it was in older GT's).

To set 100.0 BCLK, set spread spectrum to 0%. And the ME must be enabled.

 

You just killed their fun oc’ing their locked down babies

 

no need bclk ,,my is bad around 105bclk ,,and different vs 99.6 vs 100 or 105 better set minimum + raise cpu ratio -unlocked cpu
or on locked cpu use only power limit "bypass" IMON ,,and load line ?? or raise VR ,,what works

new fw 12 is hard ,,thing PCM is problem ,,not tested ,,get hard brick ,,or need custom from ""svet"" on my old nb before same ,.,hard safe new bclk ,,but work,,,now is all values allowed
,,old 7820hk + last 11.8fw

edit..
...some setting in ICC tab ,,EOP,,type of change
on my old fw not work "full numbers" 10050 ,,need similar 10047 etc ??? or "f4 key" I think
+must working me driver ? I've tried a lot before

 

This has to decoded by NASA..
Hello bro xd

 

,,,no need unlocked bclk ,,,on old fw is easy way ,.on new fw 12up is hard or need modded from MSI ?? ,,risk -full brick
and locked cpu ?? still get small bclk range or any problem ,,not works all setting in bios
8750h is locked ?,,get power limit use "imon ,,scale ,,prefix ,," ,,this "bypass" no-power limit
vr /tdc VR? current or iccmax limit ,,loadline -accurate your setting ,.not or lower "VID-boost" better OC
,,what works test

bclk is bad idea ,,not easy setup
read before "hwinfo" read other problems/limits
,,my 7820hk is unlocked is easy setup and cooling is problem ,,75w-100w cpu need gt series + lqmetal and similar ,,all nb get temperature limit
