My guess is that DM machines might not have a compatible BIOS for 20/30 series cards.

 

I think that might be part of it, the TM came with the RTX20 series, so it may be that the RTX 30 series just need a modded display driver to work. I might first try to just flash a TM one and see how it goes, I can always flash it back too.

due to baked-in firmware sig checks.

 

But we already have many who have successfully installed a 3070/3080 into older P870 or P775 models, I just don't know if they were all TMs or older DM/KM ones. We will see.

So with 2080S back in I can boot to Linux Mint 21.3 Mate after I mounted the ISO onto the usb using Rufus. It works! So now how do I get into windows and install a display driver? I think I missed the connect there.  Also external monitor doesn't work - unlike the 3070 - but even though I get no display it is obviously still booting into windows desktop. I can even shut it down using shortcuts.

 

@1610ftw

 

That is too bad - I was hoping you would be able to drive an external display with the 2080s. Have you tried both HDMi and display port?

 

In any case you could go into the advanced boot options menu and boot into VGA mode to see if you still get a picture or if you have set it up that way you can also access the laptop remotely.

So trying to use the CH341A to flash the bios - anyone know what our BIOS chip is? It didn't read it automatically.  @srs2236 @1610ftw You guys have any idea?

 

I got the XMG TM bios, Dsanke TM bios, Clevo TM bios, BAKED bios so a few to try out.

[anassa]

The bios chip itself has the marking of:

 

MP8715
F4729217
MPSF27

 

Still not sure manufacture/type to choose.

 

 

Just realized that I thought was the bios might not be and I still need to find it. 🤣

Sorry, can't help you with that. Better to rely on members who have done it before with your or a very similar chassis.

 

I am also not quite convinced that it is a bios thing when you can already see the card in Linux but one of the more recent unlocked bios versions may also help you in other ways so it cannot hurt to try. You indeed want to choose your bios wisely as there have been reports of issues with audio and Thunderbolt connectivity iirc. but I am not familiar with the 7xx DM2/3 chassis.

[anassa]

I also remembered that a few years back when I first flashed the dsanke bios I don't think I flashed the RTX version since I only had a 1070 with no RTX cards in the books for me. So flashing just the GTX bios might be the issue. I am crossing my fingers that with a newer bios will work - even if I have to use a modded driver. We will see

Hi,

test the following things:

1. is the eDP cable seated correctly and do you have another one to test. Be careful when plugging and unplugging it. It always has voltage with battery and also without but with power supply. Because of short circuits!!!
2. is the MXM port really clean? All DP port channels have extra pins. You have to check that. It is best to carefully blow it clean with compressed air!
3. do you have another display to test?
4. the other things are very difficult to measure. Do you know how to use measurement technology? And you must be familiar with the schematic of the P755xx.

Which display are you testing?

hi. i confirm this with 100%. i have p775tm and install RTX2080 Super, my 330w ac power charger is power off when loading only GPU, and laptop shut down in stress gpu+cpu together. i bought eurocom charger 780w and my power consumption overall in stress tests Aida64 CPU stress+Furmark = 400W power consumption. 

Therefore, we can conclude that the consumption is very high and that the power supply cannot take the laptop in working condition. and I say right away - no power plan settings DO NOT CHANGE the power consumption (battery saving, balance, enterprise, silent etc) of the video card; it does not work with the cool control center v1.0 v2.0 versions and different revisions. Also, the heating is very high, in 5 minutes the temperature in games is -90 degrees and no matter what settings - medium or ultra - the video card still consumes 205-210 watts according to HW info sensors. and when play in games gpu drops frequency to 300 mhz core and 100 mhz memory to 10-15 sec, then power full up, after 2-3 mit - again drop... rtx2080s on p775tm not working properly. and no modded Vbios with reduced TDP down (150w max or 175 w max). only one for x170sm

 

maybe try flash another bios and EC. i use XMG TM official bios 1.0.28 and ec 1.0.16,  and try official clevo bios 1.0.29  - startup and loading - no issue. Same issue as you -  in bios and windows - Unknown video card.

Do you  mean even with eurocomm charger you have problems 🤔 

As far I know my friend got it to work with his 775tm1 with two 330w charges on y splitter...with custom eurocomm bios and some modifications on bios menu..also with i9 9900kf but I need to ask him again what tmeps and power consumption overall he has 😅

[zex4]

I thought there is no change that the 80 super would work on tm1 but maybe right bios helps 😉  I will ask him detailed lets see

@Developer79 Thanks for the input, but I think you missed the part where with the GTX 1080 installed everything works fine.  So I am 90% sure it is not a display issue.  If I had switched out for a new one or something along those lines then it would make sense.  But this is a case where only the graphics card has been swapped, so there is somehow a disconnect of recognition or something between the GPU and the internal display, which is why I think it may be bios related.

I think he had a different issue where he was able to boot / install but when it was on load it would shut off, and he used eurocomm charger and it worked.

I think the problem is I don't have a TM1, but a DM2 😅

[zex4]

I am not clevo hardware specialists but It might be the tm1 power delivery system is more powerful than dm3 series...mostly it should work on p870 serie fine when you consider they sli system 😅

Of course power plans won't change anything. The idea is to change the TDP in MSI Afterburner or any other GPU overclocking tool of your choice. Clevo Control Center doesn't support this.

 I tried to change anything in the msi afterburner - nothing changes, 
the frequencies do not drop according to the changes set on the graph MSI. Not allowed settings... 
The video card is defined as unknown in the BIOS. RTX 2080 regular arrived - TDP -155 watt maximum, 
also the control center cannot do anything with the energy consumption plans. 
but 150 watts is better than 200 for me.

I understand that the card rtx2080super is  not for this laptop P775\P750 (Wery hot,many trubles with power, not allow power plans etc...))

i mean that the standart (stock) ac adapter 330w  cannot cope with increased power consumption, it will simply turn off when the load exceeds 330 watts. and the average load in games is 310-340 watts, and at maximum load the stress test is 400 watts. only Eurocom or two paired ones can hold such power. because power 2080Super  - i fixed on 216w+ cpu 8700k in turbo boost 118w + LCD\SSD\Keyboard\fans - 50w

Was this score overclocked? Or just default 2080 Super? Also you have a P775TM right? Not a P775DM2?

Its default 2080super with no power limits, because any limits not working in p775tm with rtx2080super. I fixed max for power consumption on my laptop was 216w for only GPU, i try oem rtx2080 and power consumption max was 168w that much better and corder than rtx2080s 

I have p775tm1g , and one remark - with rtx2080s g-sync not working, with rtx2080 - working perfectly. Best choice for p775dm3 tm/p750dm2/tm on my opinion - is rtx2070 or rtx 2080- because no problem with stock power supply 330w, if you install 2080super, power consumption can be greater than you have in your power supply and laptop extremely shut down...

@kela-slk Oh nice, so you got 10,814 graphics without any kind of overclock, looks like avg is around 10,500 so that is right on. I have the eurocom PSU so I am not worried about the power draw.  The biggest difference is that I can't even see anything on boot up.  You could, you could install drivers and everything even if it pulled too much power - it worked for you.  That is where I think it is a bios issue for me because of DM2 vs TM. So I want to get it to work then see what I can do to tweak it. Or at least try

Do you try shange legacy/uefi boot?

Do you have bios from dsanke modded with unlocked hidden menu? 

Soon i will get p750dm2 (1-2 week) and i try start rtx2080super with this laptop.

What I see in the bios if UEFI boot enabled/disabled - should I disable it? There is nothing about legacy.  And yes I have the dsanke bios that has everything unlocked.

 

Sigh . . . just reinstalled the 1080 so I can bios flash using afuwin64 (in windows desktop) instead of afudos (from bootable usb in dos) since it would not flash.  I got the 1080 back in, it worked fine, then search for the BIOS to flash again - did not install the 1080 driver because I was just planning to flash the bios - but windows auto installed a driver. Then I decided to run a Timespy pass just for fun - but it crashed and now it won't even go into the bios anymore. It starts - screen stays black, beeps once and just stays on but dark. This is with the GTX 1080, so there should be no problems.  😒

 

Update:

Pulled the 1080 and put the 1060 in, to see if it was the GPU, it booted right up with the 1060, then I tried to use afuwinx64.exe and flash the bios. First time I got the "10 - Error: unable to load driver", couldn't get it to work, but I had found and downloaded the XMG P7XXTM1 bios update 1.07.28 file which included another afuwinx64.exe file.  This one actually worked.  First tried the modded bios, but got the "18 - Error: Secure Flash Rom Verify fail." So then I tried to flash the XMG bios. That one actually worked!

 

So now I have the XMG P7XXTM1 bios for my P750DM2, in HWinfo it also shows the laptop as a "XMG P7xxTM1" laptop.

 

Now to reinstall the 2080S and see if it will work. . .  and it didn't. 😕   In the bios it says:

VGA Card: Unknown

VBIOS Revision: 90.04.97.00.7D

VBIOS Build Date: 02/14/20

 

The screen still doesn't load into windows and stays dark. I don't get it, shouldn't it just need an .inf mod and work? Why doesn't it display anything for windows, but shows BIOS fine??

 

@kela-slk Which bios do you have?????  Do you mind making a copy and sending it to me? I want to give it a shot, because I can't figure out why in the world the screen is staying dark when loading into windows.

 

Thanks

Can you make a backup of your current BIOS that you successfully flashed the TM version and send it to me?

I just sent you the .rom that I used to flash the XMG TM bios.

 

Picture of the dsanke bios

 

Picture of the new XMG TM Bios:

 

Picture of XMG P7xxTM1(-G) bios in HWinfo as a TM:

 

 

I wonder if there is not some really simple bios setting that I just needed to change and that both the dsanke bios and this XMG bios would have been fine. 😑

I have XMG official bios downloaded from XMG ULTRA 17 (E19) (ID: XUL17E19) - Download Portal (schenker-tech.de)

same as you flashed on your p775dm2\3

 

if you can boot in bios and normaly change setup bios options-  i think problem is OS, can you reinstall new OS? You have win 10 or win 11?

after insalling rtx 2080s i automaticaly install fresh OS, and not check booting with old windows. i had win 10 but  a couple of weeks ago I upgraded to Win 11 for free, although I like Win 10 better.

 

i have too - not recognize in BIOS RTX2080Super - just unknown graphics card? and version VBIOS is JUST ONE, there are no other versions! only for rtx 2080 there are two versions. for super there is only one 90.04.97.00.7D.

I have Windows 10, but if we have the same bios then it doesn't seem to be a bios problem.  Maybe I should re-install windows as you mentioned.

To be honest I am surprised you haven't tried this already😅 I think I asked you before if you can boot from a USB windows installation. Because if you can, it's 100% a windows problem.

I was able to boot from a bootable USB with Linux on it . . . it would be embarrassing if it was just a Windows issue . . .😓

[kela-slk]

just install rtx2080 not super, TDP is 150w and its very well, because super version is overheating on stock clevo trx heatsink. in bios recognize as rtx2080 and in bios automatically install drivers. soon make tests in the  same conditions as RTX2080S and I can conclude whether it is worth installing a hotter rtx super and how much faster it is.
