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

you have linux or windows OS?

Windows 10.

 

I just tried booting Linux from a USB to see if the screen would turn on.

And? Turning on or not? I cannot understand, your laptop boot to bios on internal lcd? Or not. Black screen after loading system or after power on?

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.

 

I just found the 2080S for a really good price ~ $300 USD, so I wanted to give it a try, especially since I don't need to worry about a different heatsink like I do for the 3070.  I also want to do the testing. In my thread (LINK) I am also testing different GPUs, I tested 1060, 1080, now I want to do the 2080S, then 3070.

Yes, I had said in a previous comment that it did work:

 

It turns on fine and loaded Linux Mint. I should have tried Windows 10 earlier.

I asked him a bit detailed...again he have a p775tm1 with a eurocomm x4c custom bios...delidded i9 9900kf overclocked...he modded and overclocking his 2080s...no shunt mod but he filled the empty chip spots with something to gain more stability on overclocking....he has the watercooling heatsink from ali for 20 Series otherwise the air cooling hits its limits easily he said....

He will check how much power draw he gets while using the two 330w power supply with y splitter...bdw he is from UK..

Hi. Just try rtx2080s with my p750dm2. Didn't work, just only boot logo ORIGIN and stuck. No entering bios, nothing boot, no post. I try changing ram and cpus- no affect. But laptop have oem bios and i not try flash Dsanke or more young Bios version. Bios is 1.06.08 EC is 1.06.06. 

Later i will  flash bios from dsanke and XMG ultra 15 and try starting on new bios. Now logo just freeze.

I see TS not responding for answers or test. 

Conclusions: RTX 2080Super working flawlessly on p750DM2/DM3. I flash dsanke bios, which ported from p750tm and no freezes, booting normally, recognise as in p775tm - standard Microsoft device, but all scanning programs detected well. I confirm working p750dm2/dm3 with all RTX20XX /Super versions, but need Dsanke bios. Some proof pictures. Custom heatsink system LOL

@kela-slk Can you attach the dsanke Bios you used? There are a few of them. I just tried to boot from a windows USB and it didn't work, still dark screen.

[anassa]

Reflashed to the dsanke bios.

 

Used the info from this thread:

 

Flashed the Bios from the file called: P7xxDMx-0729-9900ks-128G

Flashed it without any issues, so now I am back to the dsanke bios but still doesn't work. Still a blank screen.  I have still one idea left to try, so we will see.

 

Also @kela-slk what display do you have on your P750DM2?

[anassa]

To test to see if there is some other reason, I am going to try the 2080s on a EON15-X (P750DM2) with a 4k panel from Origin, but now I can't flash a different bios.  It keeps on giving the "Security Flash Verify Fail" error.

 

I have tried to flash the XMG bios, the dsanke bios, (both that worked on my other P750DM2) and the normal clevo bios.  All have the same error. Did Origin do something to block flashing?

 

I use afuwinx64.exe, and tried afudos.exe with usb boot via DOS, but also but that didn't get anywhere either.

 

I "cd" to where the bios.rom file is, then use:

afuwinx64.exe BIOS.ROM /X /P /B /N

But it just gives the error mentioned above.  It has worked fine on my other P750DM2.

 

Actually... I just remembered the other P750DM2 is also an Origin EON15-X. Not sure what is up, now that it doesn't work.

 

Anyone have ideas?

 

I might just have to find the original dsanke post that has instructions

 I use Full HD display in p750dm2, but in clevo p775tm have 4k. Working in both laptops. 

Maybe you have defect rtx2080s or gpu with issues... 

Do you try your vga card on another laptop? 

[kela-slk]

Security flash error maybe need disable in bios Secure boot and then flash new bios

[anassa]

Thanks @kela-slk a bit of a late response - life has been busy, but I never got the 3070 or 2080S to work.  I did find a 2080 for cheap that works without any issues. So at the very least I have my daily laptop back! So I am really excited for that.  I have a spare P750DM2 that I will play with to get the 3070 up and running. It will eventually go into the wife's laptop as I found a 3080 for myself. I will update once I have the test/spare P750DM2 up and running.  Once that is good to go I can swap it over.

I bumped into a similar issue today. I have a P775DM2-G which ran fine with 9900k and 1070. It has a modded BIOS 1.06.13 by dsanke, and a 330W PSU. I put a 2080 non-s inside with a new heatsink today, and it stuck at the bios logo. Keys were not working so it didn't even get into BIOS. I swapped back the 1070 and then it booted into Win10 right away. 

I felt it really strange how the BIOS can limit GPU which has its own vBIOS, but this thread somehow convinced me. Is your machining with 2080 running a dsanke bios 1.07.29? 

[kela-slk]

i have Dsanke bios flashed, but dont remember what version bios and ec. but p750dm2 working with all 10series and 20series graphics cards

[taiyang]

I just confirmed that with Dsanke bios 1.07.29 migrated from Z370, my P775dm2 with Z170 now works fine with 2080 non-S.

 

Flashing this BIOS 0729 is tricky though. A programmer with a clamp is straight forward, but with software flashing in OS, the laptop needs to be completely cut from any power after flashing, according to Dsanke:
