How's the performance result from others? Were you running off AC adapter or battery?

 

AC adapter connected
Well b4 the gt 75 i was using a

dell Inspiron 15 7537 b4
I7 7700 hq
16 gb ram
1050 ti 6gb gpu

So after shifting to the gt 75 i just feel like the performance has gone up to like 10 15% more thats it.

Its actually supposed to perform much better ryt

(Correct me if I'm wrong )

 

1. i7-8750H is about 40% faster than i7-7700HQ.
2. GT75's GPU is 1080 which is superior than 1050 Ti.
3. Adobe After Effects can support CUDA, see below link.

Cool.

What's the performance like on CPU versus GPU?

 

Never tried

When its set to gpu
The gpu usage shows like 2 or 3 percent thats it

You should also see this:

Go into your BIOS, then go to the OC menu and increase the VR Current Limit from 544 to 800, your CPU performance now should be top notch and not throttle.

 

That wont cause any issues ryt??
Can u help me out with some more tips

what the heck is "ryt" ??????????

Increasing the VR Current limit can be done on any CPU and it doesn't cause any harm. All it is telling the motherboard that it can pull as much power as it needs for the CPU so that it is never short of power and thus does not Throttle which is what you probably are experiencing.

 

@Abhishek Kumar

It would be useful if we knew how the CPU behaved during the render (as you can see from my previous post, the GPU doesn't make a considerable difference, it's all about the CPU).

To see what happened during the render process, you would need to re-render it while monitoring with hwinfo64:

-open hwinfo64 sensors and expand the window with the double arrow button <--> (we need to see the VID, clocks, core usage, core temps, cpu package power, gpu package power, gpu usage and clocks), keep the window opened,

-right after you started the render, press the clock icon in the hwinfo sensors (to reset the registered values) and keep the hwinfo window opened while rendering,

-just before the render is finished, take a pic that captures all the values from the hwinfo sensors,

-post the pic here using this: https://postimages.org or the app https://postimages.org/app (with imgur they are not easily readable).

Alternatively, you could setup hwinfo to save a log file using the icon with a file and a + sign from the right side of the clock icon.

Just press the file icon and set the name and the location.

After that you can start the render process.

After it is finished, press that file icon again to stop logging.

Post a link to the saved file here so we can download and inspect it.

 

Please use complete sentences to type here.
We don't need someone typing "Ryt for "Right."

This isn't freaking Skype or Discord. Use proper English please.

 

Maybe same problem Intel i9 Laptops are NOT Worth It - Benchmarks vs i7 8700 Laptop

 

GT75 8Rx (as well as other models) can severely underperform when it is all stock.

 

I am sorry
I am new here and i dont no much about this forum

Have you tried enabling full fan speed? Maybe it will lock up for some more performance.

 

I'll surely try that @Papusan

Sent from my ONEPLUS A5000 using Tapatalk

 

I did enable the full fan speed all it does is turns on the cooler boost mode at the startup

 

Oh’well. Then run full fan speed and see if the performance being better in your tests. Compare results with and without max fan speed.

 

@raz8020

Bro here is the link to the log file

https://mega.nz/#!2DIhUKpL!-s6h6jLmH7BiroREVKuu2qF6vhU4Ld3yd8ugUcTiK0A

please check it out and do help me

 

Enabling full fan speed sets the CPU fan speed to 100% in Bios. Better to just use "MSI Silent Option" and set it that way to 100%. BTW the curves are made for the older Skylake modes. On Kaby Lake and newer, The 85% fan speed setting gives you maximum RPM (5000), and the slider goes up to 150%. So anything above 85% is pointless (you'll have to test this for yourself, this applies to using MSI Silent Option on the Kaby Lake GT73VR and GT75VR, it might be different on the GT75 Titan).

Also setting this option in the Bios acts similar to a "FAILED POST", which could cause custom RAM timings to revert back to default, because the "POST Loop" that happens when changing this setting acts like a RAM timing tweak fail, which is very annoying when using custom RAM settings (i'm running the default Kingston valueram which defaults to 17-17-39 2T, at 14-15-35 1T.

Ok you guys did it. I'm bored again.
Now I'm setting my RAM to 14-15-34, 1T, tRTP=5, tRFC=270 tREFI=65535.
Because I like reinstalling windows.

It was 14-15-35 1T (tRTP=5) before.

 

I have some good news and some bad news!

The bad one is: the main limitation seems to be in the rendering engine, since apparently, it can't efficiently use the extra cores (this theory is based on the level of core usage, a log from the dell notebook with 7700HQ might be useful to compare the core usage or even better, you could set the core affinity to re-render with the titan while using 4 core/ 8 threads, but for apples vs apples comparisons, you need to limit the multiplier to ~ the average sustained speed from this run, which appears to be in the 3.8Ghz range, the time difference between the runs would indicate the difference in % between 4 cores and 6 cores at the same speed).

The good one is: the performance can be improved with all the mods and settings that you'll find in this thread, but will mostly depend on the highest clocks that could be sustained under this load (the extra cores don't make a considerable difference).

Some info from the log:

-you triggered the thermal throttling limit for a v short period while you were PL2 limited (the performance drop was negligible), this could be due to the more relaxed fan profile,

-you were PL1 limited at 45w during the rest of the test, which would explain the lower clocks,

-it appears that the power plan or sst settings that were used, are not those that favor the maximum performance (see the C0 residency).

If you do the math from 3.4Ghz to the avr. clock speed in the log for the GT75, you'll find that the difference in % coincides with the performance difference that you mentioned before (between the dell with 7700HQ and the GT75).

 

1.4v @ 4.5 ghz?
There's your problem.
That's 100C even on a 7820HK.

And this is an i9 8950HK unlocked CPU right?
I didn't see you post the CPU specs in any of your posts.
You said i9 and someone else said i7 8750H. I have no idea what you have.
Do you have an i9 8950HK or i7 8750H ?

Set your IA AC DC loadline setting in Power and Performance ->CPU VR Settings ->Core IA Domain to 1 and 1.
This will stop your CPU from getting 1.4v and then thermal throttling.

Then manually reconfigure your voltages.
Try 1.25v static voltage (1250mv). If you blue screen, Try 1.275v (1275mv). If that is unstable, try 1.30v.
Do not go higher.

 

I guess this isn't bad for 4x8GB of Kingston 2400 mhz DDR4 Valueram.

 

@Phoenix Well it seems I am getting some random FPS drops while gaming. You mentioned that previous nVidia drivers are considered more reliable. Which version would you recommend? Once I have the proper version, is it as simple as uninstalling the current driver, reboot, install recommended driver?

 

Thank you soo much. @raz8020 and @Falkentyne

I have an i9 8950 hk

Just one question how do i do that will i get these settings in the OC menu in the bios? If not then where will i find them


Thank you so much once again.

 

I'm confused, you said that I should never use static voltage. I had static voltage of 1.25v with -0.120 undervolt and you said I should use adaptive voltage only. but here you're saying he can configure to static voltage?!

 

You can either continue using new drivers and go to nvidia control panel -> manage 3d settings -> program settings and then set prefer maximum performance for all your games (you might need to create a profile if it does not exist yet by using the add button) OR you can go back to 391.48 drivers if you do not need the fixes in the newer versions or if you do not need newest drivers for your games. You can refer to Phoenix's thread for those here: http://forum.notebookreview.com/threads/msi-gt75-titan-drivers.800622/
I noticed any newer driver has some power issues in adaptive/optimal mode in demanding games but max performance works accordingly. I guess this happened when they were trying to fix all the power-related BSOD issues and black screens etc.
Also I recommend using DDU to remove the drivers before reinstalling other versions.

 

I saw your video of witcher 3 and is impressive the low usage on 8750H cpu.

 

Hi, don't you have an i7?

And I said do not use static voltage if the IA AC DC tweak is not done.

 

Yeah I think I have a good balance now with temps too ^^ I am happy with it now. GPU stays between 75 and 80 even on 100% usage with just 3200rpm. The noise is now acceptable, not over 4000rpm anymore like stock! The cpu fan is mostly inaudible in games, maybe sometimes hovering above 2000 rpm. Not bad to my standards.. obviously not silent at all but it's still a laptop.

 

Thinking of getting this laptop. I took back my Alienware 15 r4 due to the thermals. Does the GT75 with 1080 have good thermals? I really want a laptop that I don’t have to undervolt.

 

How do i do those settings you mentioned

Edit. Almost none of today’s laptops with Coffee BGA chips manage to hold stock clocks (max boost 24/7) and within normal temp with default voltage. The weaker i7-8750H or the +$600 i9-8950Hk doesn’t matter.

 

You need to undervolt both the cpu and gpu for it to run acceptably on stock paste (at least if room temperature exceeds 20 degrees celsius). With sth like gelid gc extreme it might stay below 90 even on stock voltages... I have to say I have had more thermal issues with the 1080 than the 8750H (it is the lowest cpu you can get in this laptop after all). Even after repaste it was going really hot, with high noise and still reaching 86-87 degrees on the gpu - I was disappointed... until I undervolted and OC'ed it. Need to keep in mind that even on stock settings the performance and power usage are higher than stock founders edition 1080 and this is a laptop we are talking about. Now it runs sweet ^^ And indeed i9 is pointless on stock paste imo even if you adjust voltages... to take advantage of it you NEED liquid metal.
I don't think there is a laptop out there that can handle the performance of these components without undervolting OR throttling.

 

Ok, should I get the 1070 version? I’m kinda worried if the 1080 will overheat

 

Check Novigrad when you get there. I get much higher CPU usage/pwr/temps in Novigrad compared to the rest of the game.

 

The 1080 will not overheat if you either run the fans very loud OR repaste it and undervolt... but that is up to you. I could not stand the noise on stock. A 1070 will have considerably less performance due to power limitation unless you do mods that falkentyne did to his 1070 and buy a bigger power adapter. Seeing you don't even like undervolting I guess that won't happen.... so if you are happy with less performance, the 1070 is an option. But I don't see what is so bad with limiting the voltage? Due to the power limits, a stock 1070 will still only stay around 0.9V or less most of the time anyway (pretty much 100% of the time in demanding games)... the 1080 is just more of a wild unleashed beast which is why it runs so hot. All I did was to make it behave similar to the power-limited card by capping the voltage in afterburner, at which point it is still substantially more powerful than any 1070. Add some OC and I am the happiest laptop owner alive.
In reality it means something like: the 1070 in these laptops is less powerful than a desktop 1070 while the 1080 version is on par with a decent desktop 1080. Just go watch some gaming videos on youtube. Unless you can get a super nice deal on a 1070 gt75 I would not bother - but that is my opinion.

 

I’m not against undervolting. I just figured with the massive cooling system it would perform well under stress. That’s what I’m tracking down in a laptop now that my AW 15 will be gone soon. Is the GT63 just a GT75 with a smaller screen? Also in IBUYPOWER I have the option for them to do a kryonaught grizzly paste before they ship it to me.

 

Can anyone help me with this please

TDP power mods won't work on any 6 core system pascal cards unless they're done by hand manually with your own custom editor and hardware tools or shunts and no one has done that this way to a MXM card, only to desktop cards. The existing editor is too old and won't work with any card that come on 6 core laptops, only on the older 4 core laptops (the vbios is different, blame Nvidia).

The GT63 is a 15" unit. The GT73 is a 17" unit. The cooling system in the 15" units is not as strong as in the 17" units. The old MSI 16L13 15" barebones layout (with LGA CPU) is based on the GT62VR model.

 

Yes I have the 8850H and I did mention when I asked that I set IA AC/DC to 1 in the BIOS but you still said never use static.

So just to make sure again:
I can go back to my original settings of static voltage with core voltage 1.25V and -0.120v undervolt like in this screenshot if I have IA AC/DC set to 1 in the bios (which I do), is that correct?

 

Please help me overclock my laptop safely
Please it's my first time please help me

Hi tweety78. The original reason I said to not use static voltages is because whatever you put for static voltages will be automatically boosted by 100-150mv at full load due to the default IA AC DC setting. So the voltage you put in for static is nothing close to what you are getting, making this option completely worthless and misleading.

When you set IA AC DC to "1" then the MSI VID boost shenanigans is disabled, so then your static voltage functions properly. MSI also does 'voltage droop compensation' by an internal setting which cannot be disabled. This is why the "DC" setting has to be set to 1, rather than 179 or 180 (which is Auto/default). The IA DC setting tells the Intel CPU how much to *REPORT* to the system the droop in the VID, based on current going to the chip--note that this setting does NOT actually droop the real voltage! that is handled by the onboard voltage regulators; the Intel designed specification for vdroop is dropping the voltage by a factor of 1.80 mOhms at full load. This specification on desktop systems can be overridden by something called "Loadline Calibration", which intercepts the CPU VCORE directly, rather than the VID).. The higher the DC setting, the more the VID will drop at full load. The actual VID going into the CPU itself is controlled by the IA AC Setting. How much VID is reported (after the IA AC setting is fed into the CPU) back to the operating system is based on the IA DC Setting (and some other factors).

On a Clevo or eVGA system, setting IA AC loadline to 1 and IA DC loadline to auto (or 180; 210 for coffee lake LGA systems) will prevent the voltage from being boosted at full load, and will show the VID to drop by a factor of 1.80 mOhms at full load, which should correspond closely to the voltage the CPU is getting. However MSI systems actually internally "remove" the intel designed voltage droop, which means the IA DC setting must also be set to 1. If this makes sense.

In a twisted way, this is another reason why if IA AC DC Are both set to 179 (default), why at full sustained load (continuous load), the VID Shown will be much lower than the actual VID going into the CPU, because the IA DC setting will droop the VID by 1.80 mOhms of current resistance, but MSI's internal "Loadline Calibration" has already removed that droop to begin with, causing the VID to be misreported as too low.

You should google what Loadline Calibration actually is first.
Note: Loadline Calibration (LLC) functions DIRECTLY on CPU Vcore.
IA AC and IA DC loadline functions directly on CPU VID.
VID is not vcore, however depending on the design of the laptop or desktop, VID can heavily influence vcore, and can be very accurate in relation to vcore, or very very inaccurate.

The really high VID spikes you see with IA AC DC=auto, are actually done at very light load, due to fluctuations in the voltage regulation, where IA AC will boost the VID far up, and IA DC won't report any droop at all.

Ok you want the TL;DR version right?

Ok. If you REALLY want to see exactly how much your MSI laptop is boosting and falsely reporting your VID , set IA AC loadline to 179 (or auto) and set IA DC loadline to 1. This will cause the full load sustained VID to be accurately reported (not 100% but very close).

Then watch what happens at full idle, then at full load (this will be no different than IA AC DC=auto, except THIS time, the VID will rise at full load. Prepare to have your mind blown).

Now if you want to see a grossly horribly inaccurate VID, try this:
Set IA AC loadline to "1" and set IA DC loadline to 400.

Watch what happens to your CPU VID at full load. Just watch.

Have fun.
(note: for some strange reason, heat and power draw are slightly higher at IA AC=1, DC=400, rather than IA AC=1, DC=1. Just please don't try something utterly stupid like IA AC=400, DC=1, please).

 

Shouldn’t it be 210 ?
