*** The Official MSI GT75 Owners and Discussions Lounge ***

Wow I never knew that existed. I wish we would get the GT75 guts in that chassis. The whole red and black gamer look isn't all that classy.

 

The look of WT73VR actually was one of the first design MSI had before besides the fancy red look for their gaming line, for some reasons they decided to stick with one unified image/look.

 

They should have went with the all black design. Way more premium and classy look imo. Any way to get a Titan with those black accents?

 

Sure @Ghost 350
Remove it and use primer .
Let me check it and show you later some pics


Primer is done. Thanks to my second hobby flames of war I have some primer at home. First layer is done maybe I will do two more.
I one of the parts is broken **** happens..


Three or four layers later

 

Worktime 20-30 min for the primer work.
if you will try it by your own i recommend to remove the hs that you have more space to remove the the rear frame of the vent area these are clipped. it would be much more easier and the risk to damage parts should be lower.

And back at my gt75vr

Last but not least the complete view

 

There would be a number of options, although with my experience, they do not work as well as you would think. Often they are unbalanced and result in a bad experience.

 

I use the old NC-820 clone cooling pad (Xotic PC used to sell this, but overpriced), that was a clone of the Zalman pad., as an 'elevation' platform. The fans are worthless in it but it still works very well as a lap platform (and a bed platform too!)

The notepal U3+ is not suited for putting on your lap.

 

Wow that looks great. What about the red accents on the screen lid? Can those be removed easily or do you need to dismantle the display?

 

dismantle of the display is required for this.

@Ghost 350
As you can see on this pic the red parts are not easy to remove. Looks like glue or something.

 

I saw this in the kitguru review of the GT75 with i9. They also said that they were reviewing a competing product that used one 330w power supply. alienwares model comes with one 330w psu. What do you guys think? Could the updated gt75 be run on one 330w psu? What do you think of MSIs rationale for going with two psus?

 

MSI has always run their PSU's at about 80%, and not pushed them to rating or beyond. They are cheaply made and often aren't treated well by their owners - buried under stuff without proper cooling space.

If the power draw maximum is 320w at stock testing for CPU / GPU only, there is another 35w-45w for the rest of the system, probably more when at maximum performance and all the fans are at full power, and that's well beyond a single 330w PSU.

I'm surprised they didn't quote the full power drawn from the wall, since that's easy to measure.

2x230w = 460w > 330w, so it's gonna be required for gaming and heavy application use.

You might get away with a single 330w for casual use, and it's easy to buy one and plug it in and try. Get one of those Kill A Watt meters and plug it between the laptop and wall to see the power draw, make sure it doesn't go over 300w or so, to allow some headroom. Also, watch the PSU heat, make sure it's free and open on all sides from obsticles for cooling, pointing a fan at it couldn't hurt on hot days.

Please come back and us know how it works

 

I think the AW and Asus models running with a single 330w PSU are gonna have power handling limits. MSI is doing it right by offering a single PSU for the CPU to be fully utilized and one for the GPU. Remember MSI is the only one who has a mxm gpu (besides Clevo). Doesn't the mxm 1080 draw more power than a soldered one which is found on every other laptop?

 

don't know how exactly hwinfo or what ever i use for this work but i have during some benchsession 150-160W (1920x1080 Ultra Setting Ghost recon Wildlands) or 195-205W (4k Ultra Settings) (non OC i think) on my 1080. the 1080 has a extra cable for power supply.
someone wrote or post from another source here that the i9 is running non oc with 120W in cinebench.
So you have 330W (+/- some W) with no OC asfar as i understood.

 

@JeanLegi My modded 1070 is drawing more W than your 1080
The GT75 isn't going to be limited by power. It's going to be limited by thermals AND by the EC. Whatever MSI decided is "too much current" for the CPU to be pulling safely, the EC will shut off the laptop.
And that will never change as long as these strings are in the EC:

CPU_CrtT = 1.CPU_ThtlT = 1.CPU_ThtlT = 0.SYS_CrtT = 1.SYS_ThtlT = 1.SYS_ThtlT = 0

And yes those exact same strings are in the GT75.

Svet said this is "interesting" and he would contact me later to see if some sort of mod to change the 1 to a 0 is possible.

A SPI programmer and changing through a hex editor would bypass ECflashwin's signed file verification (just like for modded Pascal Vboises), but if the internal checksums are calculated from space where those values are stored, either the EC will brick the laptop, or the EC will "revert" to a backup version. It's unknown which will happen at the moment. The good news is that Svet said that the EC is stored in a SOIC8 chip, the same as the bios chip, but in a different location and a smaller flash size (1 mbit). and on the Gt75VR and GT75, it should be easily accessible by the GPU fan, while the GT73VR requires full motherboard removal (yuck). So a force reflash is possible with stock.

Regardless, you would need LM repaste to even exceed the EC's power limits and power trip the laptop before reaching 100C....(unless you run some extreme intensive heavy load at a high o/c which INSTANTLY shuts off the laptop.....)

 

@Mr. Fox @Falkentyne @Johnksss @Papusan


So my laptop has Samsung M471A2K43CB1-CTD 2666 MHz 64GB DDR4 RAM which is rated at 2666 MHz but I noticed that the RAM is running only @ 2400 MHz using the default profile.

So I selected custom profile and changed the memory ratio from 9 to 10. It then ran @ 2660 MHz but is seriosly unstable. I keep getting random BSODs with anything I throw at it. I can't even complete a 3DMark11 test past the first test without a BSOD with the 10 memory ratio

Why the heck does it run @ 2400 MHz using the default profile if the RAM is rated @ 2666 MHz. and this laptop is advertised to have the 2666MHz. RAM from MSI and all the RAM SODIMMs are the same approved MSI model I didn't mix anything

How to get the RAM to run @ 2666 MHz?

image hosting 20mb

 

Try increasing the memory voltage from 1.20 to 1.30 in overclocking performance menu.

 

ok, mean while, he's the first 3DMark11 run, everything stock, CPU is @ 4.3 GHz x6



I can't run any stress tests though, trying to run AIDA64 for 10 seconds and the temps reach 95C instantly and the stress test stops due to hardware failure. Seems like this CPU is at its limits despite having Thermal Grizzly Conductonaut, Fujipoly thermal pads, and the bottom panel ventilation mod.

 

Could you try Cinebench R15 and put up Hwinfo? And what was max cpu temp in 3dm11 ? And could you bump up ram voltage? Or is it locked?

 

Change IA AC DC loadline to 1. Then change the settings in overclocking performance menu to 0.01 mOhms. Then use static voltages and re-tune your voltages. Start at 1.20v static.

You know the drill @Phoenix

 

Need som base numbers. I want the numbers most people will get, bruh

 

remind me again where to set that 0.01 mOhms? I know where the Airconditioner Loadline and DC Loadline are

I put 1.3V for the memory but the test failed after a while this this:



Shall I try more? This is BS to have to do all these things on a brand new taptop I am not overclocking it, just want it to run at what it's supposed to

 

Can you please run ram stable 2400MHz in your first tests?

Run it 4 or 5 rounds in a row. It's stock, bruh

 

Phoenix LOOK AT YOUR VOLTAGES MAN.
fix that IA AC DC!

 

so just set the IA/DC Loadline to 1 and static voltage at 1200?

no way to do that oHmss thing in BIOS?

 

RAM @ 2400 MHz:

image hosting 10mb limit

 

Set IA AC DC Loadline to 1 in CPU VR settings ->Core IA Domain
then go to overclocking performance menu->Processor->Platform Voltage Overrides Core VR Loadline Override. --->Set to enabled.
Then set to 0.01 mOhms there too.

Then set CPU to 1.20v static voltage.
Then re-test.

 

@Phoenix, shouldn't be 2666 MHz by default from factory ? or yours maybe has an issue, very disappointed

 

The default AC/DC Loadline was 179 BTW

When I set it to 1200 static voltage it wouldn't even boot, it hung at the Windows loading splash screen but I then set it to 1280V and it booted

Now let me go and change the oHms

 

Actually let's do this by the book, ok brother Phoenix?
Even though it will take longer.

Go to Power and Performance, ->CPU VR Settings, Core IA AC DC Loadline, set both to 1. and 1.200v static voltage (1200 mv).
If you get a BSOD, set this to 1250mv.

Then without (yet) going to overclocking performance menu->Platform voltage overrides->DC Loadline override and changing that to 0.01 moHms, go to windows first and post your HWinfo64 and cinebench, VID shown, on the hwinfo64.

Then when you're done, then go back in the Bios, go to that Overclocking performance menu->platform voltage overrides, change that DC value to enabled and 0.01 mOhms, and then re-test HWinfo64. If you get a BSOD after THIS test, revert that value back and just keep the original IA AC DC set to 1.

 

What in the living hell ? Any chance you can show me the default value? 179 ? It showed as 179? What is MSI SMOKING??

210 is the reference value for 8700K (8950HK). It even shows in the linux Intel coreboot section. Auto is 0. It was set manually to 179 instead of 0 (which is auto, which is still 179?).
And your CPU needs ........

uh....

@Papusan your CPU needs 1.280v to boot at 4.3 ghz?

That's an 8700K requiring 1.280v for 4.3 ghz.......

Oh.
My.
God.

 

what is 0.01 oHms? I calculated it to micro ohm and the value should be 10, look what I have in the BIOS, what should I choose?:

 

@Phoenix You may need to tweak ram settings if you go 2666MHz. At least from what I understand from MSI's specs sheets. And run 4-5 Cinebench rounds in a row. Thanks

 

Only 2666Mhz when using 32gb with 64gb it supports only 2400mhz. Look at the specs at the msi page

Edit:
My fault only 2 slots support 2666mhz if you use all 4 it supports 2400mhz for the ram. This is factory setting!

 

100 uOhm is 0.01 mOhms or 10. Doesn't matter
In fact set it to 0. tbh.

Actually I keep saying 0.01 mOhms when yes I do mean 1 or 10.
I keep typing the "Asus" lowest value which is 0.01
MSI uses 1 as the lowest which is 1 not 0.01.
You can also set it to 0.

Still this intel binning.....
i9 8950HK...discarded 8700K that needs 1.280v to boot windows at 4.3 ghz on all cores??!?!?!?!

@Papusan is going to be unable to eat for a week, man....

 

There are the stock settings:




I forgot to mention something, the stock settings have Intel Speed Shift disabled. I always enabled it, now I will keep it enabled and see

 

really?????????? where did you see that bro

 

Read my posts!! http://forum.notebookreview.com/thr...scussions-lounge.806253/page-89#post-10719979

 

Are you sure? this means I should make an order 2x16 32 RAM if I need get 2666mhz, doesn't it? what do you think?

 

Thank you brother.
Please check the DIVIDER to the right of VR Current Limit.
take note of that.
Set the value to whatever is "200 amps".

if it is divided by 4, then set it to 800.
e.g. Change VR Current Limit to 800 instead of 512.

If it's divided by 2, set it to 512. I'll have to look in AMIBCP to see what's going on.

Interesting about the stock settings.
Looks like the GT73VR and GT75VR also use a stock value of 179 for IA AC DC
Set them both to 1.

the intel reference value is supposed to be 210, which causes vid boost of 2.1 mOhms.
I had calculated from my own tests that the default value was probably 180 rather than 210.
Seems like i was right all along. MSI is smoking the good stuff...

anyway yeah.

 

From the msi configuration overview of the GT75 8rg:
Memory
DDR4-2400 speed up to 4 slots
DDR4-2666 speed up to 2 slots, 4 Slots, Max 64GB
https://www.msi.com/Laptop/GT75-Titan-8RG/Specification

 

Ok I opened that Bios.
The default setting for VR Current Limit is supposed to be 0. I wonder how MSI is getting these default values.



anyway please check the description.
if it says 1/4 increments, change 512 to 800.

IA AC =1
IA DC=1

Then show me a cinebench score with your VIDmin / max shown.

Then when you're done with that:

Overclocking performance menu->platform voltage overrides->Core VR Loadline Override (Set to enabled). ->DC loadline value ->set to 0 or 100. Try 0.

Reboot windows, run another cinebench.
Let me know the magic smoke results and eggs cooking.

 

thanks a lot bro, now is very clear

 

Bloody hell!! No wonder I was having constant BSODs and I formatted 4 times already thinking it's Windows 10 Flinstones 4 being unstable

 

Windows 20 Flinstones 4 come on top, bruh. You need to ask HID what they can get of stable ram setting with full testing of 2666Mhz all 4 slots on MSI. 4x16GB sticks.

 

Whatever they can get stable is not relevant to me. I am not dismantling the laptop to change RAM. It needs a full taptop surgery to change the RAM. I have not the time for this bro I am a body builder

 

Well, have you already tried the easy route? If it has 2666 RAM, that is probably an XMP profile. The default profile for my G.SKILL 3000 and 3200 laptop RAM was 2400 and the default profile for my desktop G.SKILL 3200 is 2133. The default memory profile is never programmed for the overclocked speed the memory is rated for.

Rather than setting it manually and hoping for the best, have you tried selecting XMP instead of using a custom profile? Look at the SPD in CPU-Z or AIDA64 and see if it has a 2666 XMP profile. If it does, you can probably set it and forget it.

 

@Falkentyne I'm confused bro and I have no time for so much tinkering.
Do you have Skype

 

I don't talk about this. HID test 4x16GB 2666MHz sticks in their own MSIbooks inhouse. Not yours. Then you will get info... Probably know what settings who is able to be stable.
