Looking for genuine Clevo 2080S (MXM) Vbios

[Alyx]

Hi everyone,

Let me explain.

I bought a 2080 Super for my P775TM1. The previous owner modified the VBIOS to change the TDP to 200W (which is why I bought the card). I extracted the VBIOS using my CH341, but Nvidia Tweaker doesn’t recognize the brand or model, likely because the previous owner tweaked it by another way.

My goal is to adjust the TDP using Afterburner's slider.

TechPowerUp only has modified VBIOS versions for the Clevo 2080 Super Mobile, and I haven’t been able to find the original one anywhere online.

If anyone has the original (unmodified) VBIOS for the Clevo RTX 2080 Super Mobile (MXM card, ID 10DE.1ED3), I’d really appreciate it.

Thank you

Have you tried it?

Clevo RTX 2080 Super VBIOS

8 GB GDDR6, 1560 MHz GPU, 1750 MHz Memory

Yes I already tried it, same result with Nvidia Tweaker. It doesn't recognize brand and model. My UEFI doesn't recognize too.

 

[eidairaman1]

Did it ever work to begin with? I presume you were using the igp off the cpu to read this info?

This vbios makes my GPU crash when using more than 65% load. It draw a lot of more power from the power supply and give some Vram leaks (Somes games EATS more Vram .... before they crash. If I close the game not all the Vram is free again).
Any other vbios was found online except for DELL and another for Max-Q design. Just for my curiosity I try flashing my card. result, card doesn't boot. Force to flash stock vbios.

Nvidia Tweaker Clevo's vbios. My Uefi (XMG stock) doesn't recognize brand and model too.

Which info do you mean?

I had a Clevo laptop which I upgraded from a GTX 580 to a GTX 680 graphics card. What I found out is that the motherboard BIOS only whitelists certain video cards, and if you install one which is not specifically whitelisted, the motherboard changes the reported board or device ID (can't remember) do an invalid value which will prevent the driver from installing and will probably cause nvflash incompatibility (since the read value will never match the actual value).

Since that laptop model only supports 10-series cards, likely the 20-series is not whitelisted and you have this problem.

For me it worked after I modified the nvidia driver to support the supposed fake ID. Worked great. I don't think I ever got around the nvflash incompatibility, but I can't remember.


I don't know why you are trying to flash it. You said you bought it specifically because it was already modified the way you wanted it to be modified. I can only assume that you are trying to flash it because it isn't working the way you hope and you think it has a VBIOS issue. Like I say, it may have no VBIOS issue and you may just need to approach the problem from a different angle.

Thanks for those informations. That make sense.

This laptop has been realeased up to 2080 not 2080S. So I suppose my BIOS doesn't recognize the 2080S because nobody tell him about the existance of that kind of card.

Do you know why, on that kind of laptop with MXM card we have wrong device IDs, but on desktop computer you can swap GPU without any problems and without (not all the time) bios update?

I use NVcleaninstall to install drivers.
It works nice until few days, while I didn't make any modifications.
Under load the laptop shutdown. I first suppose an issue with my PSU. I reduce CPU consumption to 20W and leave GPU to 200. My wattmeter, installed before my PSU, measure 280W, that is below the 440W (income power) of the PSU (330W out). My wattmeter is install since the beginning with this computer and reach 350W in input without issues (Max 2A at 240V is marked on it). The laptop crash 1, 2 or 4 minutes later.

Another test I did is to reduce GPU consumption to 150W (half load) and leave the CPU feel free to stay all core at 4.4GHz so 135W. I have not crash after 30mins, 86°C temps each CPU/GPU and 350W at my wattmeter.

I lauched a stress test on each individualy, CPU/GPU. No issues with the CPU, but crashes with the GPU.

I updated the drivers, same scenario.

I removed the card to look at the thermal pad and past. They were old but not too old. News ones after, GPU stress crash.

This is why I suppose something is wrong with.

I could ask to the guy who sold the laptop, but ... I am not "in good terme" with him.

Is some can just compare informations given by Mobile Tweaker :

 

[eidairaman1]

It all has to do with power, cooling and thermal constraints of these mobiles.

 

[Alyx]

Sorry eidairaman I didn't understand what you mean.

I tried to swap the ID from 2080S to 2080, to make the computer thinks about a 2080 instead a 2080S. As this computer is release with 2080, my goal was to make the subsystem ID match with somethings know by the bios, and stop with NVcleaninstall.
Through HXD I read 3 vbios from 3 2080 but different ID. Only one place (same in the 3 files) matched to be the ID.
I used HXD to swap the 2080S mobile to a 2080 mobile ID, took care about checksum, upload new vbios with my CH. But 3 tries, 3 fails.

Maybe just a clean install of Windows could resolve the crashes.

I found some people with the same problem :

Official Clevo P870TM-G Thread

notebooktalk.net

In addition to modifying the driver for rtx2080super, you will encounter the problem of laptop crashes when the video card is running at maximum performance.

Ok, you are right (I saw that are different variants of the card, my bad for not looking at a clevo one), but still does not add up because GTX 1080 was a 200w+ TDP card and had no crashes. I am curious because you cannot blame the TM power delivery (especially on TM that has a way better power intake, mosfets ratted for higher amperage), than the rest of the P870 lineup. Also the power switching is done onboard of the card (the VRM is completely on the card itself).


So I am inclined to believe that is a bios/vbios bug that involves maximum clocks.

The problem lies in the fact that they cannot withstand the load of 200w + vrm of the video card itself, since the power management system of the video card in the p870 series does not correctly manage the load of this video card (keeps the tdp of the card constantly outside the limit of 200w) which leads to DrMOS overheating and emergency shutdown. The solution is to replace DrMOS video cards with more powerful ones. After replacing DrMOS, the card no longer crashes and can withstand a load of 240w tdp.

In the rest of the discussion they are talking about take care about the thermal pads from some places on the cards.

I will try to remake the thermals pads correctly.

I am looking for a compete ID number for a 2080 mounted on a P775TM1. If some can have a look in GPU-Z.

See you

Sounds like a solder mod being required, to me not worth time or money, run the fastest supported card then replace the mobile later on.

 

[kiddagoat]

Does the card work now? Are you able to get into windows, install the driver and run the card without issue?? If so, leave it alone.

As others have noted, it is not on the approved list for that system. A very long time ago on my Clevo, when I installed an out of spec GPU, it would just show up in the BIOS as Radeon dGPU. I could read the temperatures and clock speeds of it, and that was it. It did not even support audio out on the HDMI port because the card wasn't on the approved list.

Laptop cards in general are going to be highly restricted compared to their desktop counterparts.

You are going to end up bricking the GPU if you keep messing with it.

You could try to reach out to Sager or Eurocom to see if they have an original vBIOS to give to you. I'd highly doubt it though.

Do you still need a clevo mxm 2080super 200w bios? I have included my original file.
