Mobile Pascal TDP Tweaker Update and Feedback Thread

Cpu undervolt:
If you use Throttlestop, you can set a profile to be used on battery. Also, as it needs to be run by Task Scheduler for autostart which means your laptop boots with stock speeds & voltages.

Gpu undervolt:
If you mod the vbios using the tool from this thread, you can use the adjustable power slider to reduce power draw and assign to a profile, then assign the profile to a hotkey. E.g. Hit Ctrl+shift+alt+5 anytime puts it in stealth mode. Ctrl+shift+alt+1 back to your default.
The problem will be that capping your power draw too low will drop your fps and there isn't a way to adjust settings to automatically maintain fps that I know of (whisper mode may be able to be used for that?)

EC power limits:
If Svet won't touch it you're SOL with MSI afaik. He can do experimental things if you accept responsibility and have a recovery method if they go wrong (that exact scenario was my first use of a hardware flasher)

 

CPU undervolt:
Ahh... thank you very much for that tip - will give that a try...

GPU undervolt:
Lowering the TDP would be an option but it has a draw back - the GPU would throttle. Let's assume my GPU would be able to run at 1500 Mhz at 0.7V or 0.75V - that's if I could set a -0.1V, -0.5V offset.
If I use the TDP to force the GPU to throttle there is no way to fine tune - isn't it ? Im not sure what exactly will happen but I assume it will not boost at all and go to much lower clock speeds at probably still more voltage that required...

EC:
I will reach out to Svet to see what can be done... I will also start to look into the option to use the SkyPro to flash the EC firmware - if that is possible there should always be a way back be reflashing the original firmware...

 

You could use ThrottleStop for your undervolt/overclocking. You can make up to 4 power profiles in TS. No need for other OC/undervolt tool.

Amazing Crippled MSI. Remember Gt70 and I7-4930Mx - 780/880M + the 180w psu? In normal max load would the flimsy weak 180w work exactly as 180w + Battery Turbo Boost kick in. But when the idiotic Battery boost have eating up the battery and the battery capacity runs down to about 30% and the boost doesn't work anymore (you loose performance), the 180w psu started charge again.... But this time instead drawing 200w from the wall. Yeah, Msi is well known for very crippled power handling. Amazing clumsy!!

And they haven't learned!! Oh' I forgot... They was the lead teacher/sheep for Mr. Azor and his dear Dellienware on how to crippling Alienware's first BGA MODELS in history, with battery Turbo Boost + 180W psu for laptops with unlocked processors + 980M. And we know the history afterwards. @Falkentyne @Phoenix

 

Yes lowering the power limit does cause throttling, that's how it limits power use.

Without wanting to spread the MaxQ bashing elsewhere outside the specific thread... The basic theme is that you trade a (minor*) loss of VQ for a (major*) gain in quietness. Your aims sound similar. MaxQ is a combo package of underclock, undervolt, lower power limit, frame cap, and reduced visual quality settings profiles in order to reduce gpu load & gpu power consumption & fan speed. So you can copy those principles to achieve your goal.

*this is what nvidia marketing dept want you to believe - but both concepts are entirely subjective - how much the lost performance and gained quietness means to the user depends only on the user's value of each

 

MAXQ:
I don't think there is anything to bash about the idea of MaxQ itself. But looking at the crap "optimized" settings they keep providing for notebooks I just do not think NVIDIA is able to provide good optimized profiles for the games and MaxQ - so as long as I can't define those myself for MaxQ I won't use it...
But I use the general idea for quiet some time... vsync + a custom frame limit (using nvinspector/profile inspector) + custom and optimized quality settings in game...
However it is clumsy... I would prefer to be able to just have an afterburner profile with custom clock+undervolt offset... plus - as I said - I think there is some potential for getting more performance with less power...
So I'd still love to be able to directly adjust the voltage...

 

Is this for the MSI GT73VR 7RE?
Keep me posted. If you do find an EC that works that won't brick the system, I'm all ears...

 

U65 seems to be mobo side, so it won't be on the MXM card. PEX_VDD is unclear. I did find where the main VRM and core voltage supply section is though. It turns out it wasn't missing but was in a different spot from other GPU things. It also matches the MXM card.

 

I talking about P670 mainboard, without MXM slot. But in MXM machines 5V also comes from MB - in P870DM 5V_RUN is supplied through jumper PJ69 from 5VS. 5VS is enabled by U43 IC (power switch) from VDD5, and VDD5 is generated in PU14 circuit. https://repo.palkeo.com/clevo-mirror/P870DMG/P870DMG_ESM.zip
According to P670 schematic, PEX_VDD is main load for 5V on MXM card. PEX_VDD is generated by DC/DC converter and can have maximum load about 4,5A, so inductor in this converter can be pretty big (much smaller than main inductors, but still visible) and easy to find.

 

Yup PEX was MXM side. The 22uF cap was blown short. It has been replaced and 5V is no longer shorted.

I hopefully can test the card tomorrow. I need to pull my motherboard to fit it in the MXM slot. The extra tab on the MSI 1070 hits the frame for the P150EM subwoofer.

UPDATE:

Without the card quite fully seated it is detected fine. Unfortunately Nvidia seems to have made .inf mods more difficult. My mods are getting rejected.

 

Permissions issue?

I had to give myself full permissions for each INF, one file at a time, to edit (rename original) the files in the c:/nvidia extracted 385.28. Bizarre

 

Any chance of getting this to work with the 1050M?

 

Yes. But I haven't been able to find a mobile 1050/1050ti vBIOS online. If you happen to have one, do you think you can share it with me over the cloud?
Otherwise I will see if I can extract it from some system BIOS package.

 

Sure, I'll just grab the bios from this laptop.... once I figure out why NVFlash isn't seeing the 1050.

 

most likely the version you are using doesn't support it. maybe there's a newer version.

 

Optimus maybe ?

@Vyor Can you switch to Discreete GPU only mode before dumping with NVFlash ?

 

or just find the vbios chip and flash directly.

 

It sees it as a PCI-E device, just doesn't recognize it as a NVIDIA chip.

I lack the tools to do so at the moment. That and as far as I can see the chip is underneath a heat sink and I lack thermal paste.

 

Try nvflash with safe mode to flash/extract

 

I can get you a Ti vbios tomorrow.

but any chance to make a volt editor? would be so nice to just be able to slide the voltage curve up or down without effecting the clocks

 

what I have found, that if you downvolt it with a Afterburner curve, you need to set the next lower clock before your actuall workload stable clocks to as little lower voltage offset possible compared to your workload stable clock.

otherwise you loose performance, as you have mentioned.

exactly as you have mentioned "sharp rising curve" is the issue here for some reason.

 

With desktop cards you can effectively undervolt by overclocking without added voltage to the max stable point using the normal offset method (e.g. +100Mhz on the core for example) and then lower the power slider, this cuts out the usage of the higher voltage points & because you've overclocked then that means each of the voltage points are already optimised for maximum frequency, so this is the most performance efficient way to run your GPU. (It's effectively the same as undervolting).

EDIT: or even if you don't want to lower the power slider, then overclocking to your max without added voltage is still a great way to get maximum performance for any given temperature or power limit - the GPU will eventually end up using lower voltage points at higher frequencies in comparison to stock = greater efficiency.

 

Using the voltage curve editor in Afterburner sucks, (the Ctrl-F function), it's prone to error & gives misleading results - very easy to set unrealistically high frequencies for voltage points & Pascal has this weird 'bug' where if you overclock a voltage point way above what is stable then it won't even crash - instead it just gives you reduced performance and people think they're heroes for running their card at something ridiculous like 2150Mhz at 1.0V - but they're not getting the performance that their frequency suggests. I briefly fell into this trap with my own card, where it was actually stable when dragging the 1.0V voltage point up to 2150Mhz, but performance was no more than stock. I don't recommend using the voltage curve editor, in my experience (& others) it's a waste of time. Instead try my suggestion in my previous post if you want to 'undervolt'.

 

I can't agree with you here, read my post above about the sharp curve, msi afterburner cntrl+f works perfectly, just with few nuances. took me sometime to figure this out why it gives less performance at higher clocks.

as for sliding the OC... that will not work for a laptop the way you have introduced it. and undervolting is what we need in laptops, cause the chips are highly overvolted from the box. and even if it did - there is a change of crashing in idle state because of the higher clock that can not be handled at given voltage. been there, done that

but this is still all irrelevant, I would like to see a firmware voltmod if possible, not software, period.

 

Seriously, we need a way to undervolt 1050(TI).(

 

Ah, when I read your post and saw 1050ti I thought you were talking desktop, didn't know there was a mobile 1050ti card. About your last point though, the one that laptop chips are heavily overvolted - you can completely negate that overvolt by just overclocking to the max stable frequency, all that does is increase the frequency for each of the existing voltage points - hence they are no longer overvolted & those voltage points will instead be frequency optimised. Your notebook would then give you maximum performance for any given temperature or power level. Now, if your goal is reducing temperatures, then this approach will not work, instead you either have to find a way to reduce to the power level or make hardware tweaks to your laptop to improve cooling performance. I'm still not a fan of the Ctrl-F curve in Afterburner.

 

Reducing the temperature is the goal, exactly.

 

I also want to mod the voltage without using the voltage curve. Currently I am still trying to understand the voltage table in the vBIOS, I would like to run 1.20V on the 1070 and see what's the maximum clock it can handle stably, .

 

From my experience, locking a lower voltage point (by using CTRL+L) in Afterburner lowered the performance. Setting a fixed overclock without locking, and increasing MHz offset after a voltage point (in order to compensate the temperature throttling) can bring up performance a tiny bit, like this: http://forum.notebookreview.com/thr...-feedback-thread.806161/page-10#post-10558762

 

did you try contacting @Prema about this?

 

Woa, 1.2V! I just saw your post in your link, you said already at 1.05V your GTX 1070 can chew through 270W - with 1.2V would you not fry your motherboard slot?! ha!

 

A calculated risk and he has P870 series MB, not a flimsy BGA board

 

Not yet. I am studying desktop pascal vBIOS to see if I can find any clue from it.
Also I am looking for a MX150 vBIOS so that I can look inside. The MX150 is running at 1.092V, while 1060, 1070, and 1080 all capped at 1.062V.

 

With fixed 1.05V on the 1070, the max power draw I seen in games was about 230W(or 210W in Heaven). The 270W was from Furmark(0XMSAA), not very realistic for every day usage. I tested the power between 1.0V and 1.05V, the difference isn't much. I am guessing it can take on 1.15V for every day without problem, 1.2V for benching with cold environment temperature I think it's possible. Now I need to figure out how to reach 1.092V before I can dream about 1.2V, .

 

Ha, ok, that sounds better, but not by much! ;-) I hope you do manage to get to 1.2V, but I also hope your PCIe slot survives too!

 

Hard mod it ma man!

 

what about 1050ti?

 

I also have 1070 OC and 1060 OC that i can get vbioses from, if that can help..

 

After several tries, the hard modding on core still doesn't work. @Khenglish got it working on desktop 1070, but no performance gained/observed on the MXM 1070. Now he is trying to strengthen the memory controller to improve vram overclock.

 

Ahhh so thats why he hasn't spent time on my motherboard. Stop hoarding the @Khenglish
Ill dig into the voltage mod for our 1070's/1080's this weekend and let you know if i find anything.

 

Yes, I would like to see the 1050ti vbios, so I can add it into the support list, .

The 1060/1070 OC vBIOS raised the TDP, clocks, and throttling temp, they are flashable directly through official nvflash and should work for both Clevo and MSI cards.
I got them from an unknown source, if you have them from a known/official source, maybe you can share it with us (I can link it to the first page)?

 

Maybe he has Hyper Threading enabled, lol, .
My project was paused because he's waiting for a new heat gun, haha.

 

From watching the voltage curve in afterburner, the mobile 1050 is limited to, well, 1.050 volts.

 

Wait a minute...are you talking about MXM cards that have OC Vbios? What? Do want!
Are these gsync compatible?

 

I had some equipment die that has been replaced. I should be able to put the PCH back on this Friday or weekend. Sorry for the wait.

 

they are

 

I have both 1060 OC and 1070 OC to dump vbios from actually, hold on

 

Thank you very much. What's the TDP range on the 1070?

 

No problem at all man! I was just fooling around with him
If it was time sensitive trust me i would be on top you like im top of a chocolate truffle cake.

 

I cant get nvflash to read vbios from 1050ti, it says eeprom is not supported!

 

Are you using the latest version? It came out today.
