hi Guys, I am considering the same for my 751tm1 🙂  

 

-what bios do you use? Or needs to be used to avoid black screen?

- 775tm1 heatsink mod is difficult? it there any tutorial for that?

 

thanks

Hello!

 

I use generic BIOS that is provided from Clevo directly (latest one). It does not need to be modified more for the video card to work out of the box. It DOES however need to be modified if you want drivers to install automatically and without any issues (like Driver Signature Disabling etc).

 

AFAIK not Prema or dsanke BIOS will help you with that. My BIOS has that fixed (for P775TM1, P751TM1 only). However do not ask me here or in DM's to share my BIOS as I will not do that. I have done many modifications to it and spent lot of my time trying to make it work on lots of things not just the 3080. So I do not want to give it away just like that.

 

I would like to make a small tutorial on how to do it but for now I haven't found the time for it yet. It is actually not hard at all, all that is required to do is to extract a specific module from BIOS and change some values in the module to alter the Device ID in the BIOS. For those who are somewhat familiar with BIOS modding the module is called BoardIDpei.

 

This module is absent in P870xx BIOS'es and that's why the same modifications to make driver installations work without inf mods on P870xx does not work on P775/P751TM motherboards.

 

In the module you will find multiple references to 7708 or 0877 (sometimes in HEX in bios modules the ID's are written end first and beggining last or something) which correspond to default Device ID ending for P775TM1 and probably (just guessing) P751TM1 as they use same BIOS. This needs to be changed to 7715 or 1577 which corresponds to X170KM-G and after that you replace old BIOS module with new one. Flash new BIOS and you will see that drivers will install without any issues from GeForce website and GeForce experience. Automatic driver updates will work and basically it will be as it would be for X170KM-G. (Except dynamic boost and G-Sync)

 

If I remember correctly i just changed the ID in multiple places, it probably need to be changed only in one spot but as it worked, and nothing else was broken I never went back to check which one specifically was used for the GPU Device ID.

 

Hopefully this can help atleast someone who is somewhat familiar with modding to make it work for themselves. Maybe I will make a nicer tutorial in future but for now this is best I can say about it. The tools I used for replacing and extracting the BIOS module was AMI Tools (more specifically MMTool) if you search on google UBU Tools it will have the additional BIOS Modding tools all in that package. If you are familiar with UEFI TOOL that probably can do the same trick too.

 

About heatsink I can't answer as I just bought custom from AliExpress and used that.

 

Good luck!

Thanks for the feedback? What does it mean to give it away like? If you have commercial offer let me know, thank you again.

This mod was not made with the intention to change power consumption in any way. It was just to try and mitigate the voltage drop occuring on Core and VRAM or make it more stable. Because of this I have an improvement in Core OC by 10MHz.

 

I know that it is not a lot but this mod doesn't provide a promise of huge improvoment of OC in the first place. From my very limited knowledge I think it works like this:

• The voltage reported on software is always not the same on hardware. There is some losses and because of that there is a small voltage drop on Core and also Memory.
• By adding more Capacitors as in this case OR by just changing to better quality capacitors you can minimize this voltage drop. So the better the caps, the closer the actual voltage supplied to core is to the voltage set by NVIDIA.

What I can get from this is that perhaps the voltage on core is a bit more stable now OR the voltage drop has been decreased or both really.

 

And its a shame that I didn't "push" my VRAM before but I would like to believe that it brought improvements to VRAM aswell. Like I said, I havent seen any other benchmark that has passed with 2250MHz. I would like to believe the mod has helped VRAM too.

 

For the core, as why its stable at Time Spy at 140MHz and not stable in other games I think comes down to Ray Tracing. As soon as I enable Ray Tracing it seems to crash pretty quickly so maybe it's only stable with basic DX12.

 

Also VRAM so far seems stable at 2150MHz which is still massive! And this was tested under RE4 Remake aswell at 4K and VRAM pushed as far as 14GB-15GB used. Again, if I recall correctly it wasn't stable on 2050MHz on desktop that one time but unfortunately I can't confirm whether or not the POSCAP did help my VRAM OC or not.

 

And like I said 10MHz on core is small yes, but perhaps with brand new POSCAPS with better specifications and maybe even higher capacitances the result could be 15MHz or 20MHz.

 

And I am sure for the people running 200W cards this might be even more beneficiary.

 

I am not an expert though and if there is someone who really understands the electronics and design behind all of this please feel free to correct me! I will try to find more info on the 4 additional empty spots and perhaps solder 4 more Caps but I think for them I will be ordering nice and fresh caps from Mouser or something. You can't really trust 12 year old Caps from some old broken motherboard all too much. The repeated desoldering and soldering already is kind of damaging the longevity of the cap so yeah..

I did this mod to my RTX 2080 200W too! Works great! Holds stable 2Ghz core under heavy load and the spikes down did literally disappear! 

I did add 5 poscaps too! 
Thanks a lot!

@MiRaGe what specific models of poscaps did you add? I plan to add EEFCX0E331R, 330uF;  2.5VDC.

[MiRaGe]

@FTW_260They were 330uF from this dead GPU:

 

(Tested) ASUS GeForce GTX 590 Dual-GPU Graphics Card Review | Geeks3D

 

When I open it again to add the fans I will make you a detailed photos👍

[FTW_260]

@MiRaGe @srs2236 Repeated this mod. I added tantalum capacitors on the back side of the board, and was able to achieve a stable 2085 MHz on the core, with a slight addition of voltage. The memory OC capabilities remained unchanged, only +1050 MHz. Card consumption is approximately 270W. (due to previous shunt mode)

Your soldering work looks amazing! Mine was not pretty, but does the job I guess! It was quite difficult to solder them.. Did you use hot air? I used two soldering irons with the help of a friend =D I have too much solder on the joints, but I was afraid it will not make good connection otherwise because of poor solder melting.

[FTW_260]

@srs2236Ahah, it wasn't really like that.  The soldering work was carried out by my friend, but under my careful supervision  There was no soldering dryer, only a special thin tip for the soldering iron.

You can solder them easily with hot twezers or KS tip/IS tip and hot air.

 

I did the mod also but I used 470 uf caps form a dead clevo 1080 mxm and works flawlessly.

Remember you need to use the same voltage for the caps but you can use a higher uf for better filtration and constant load.

Might be of interest to some of the guys here with RTX 2080's in their P775TM1-G's.

Seems like full VBIOS modding is making a return up to 20 series cards. Unfortunately not for 30 series😭

 

This might mean one could raise power limit to 200W and still have a working display port out on Clevo machines. (Alienware 200W BIOS kills display port functionality on Clevo)

 

Not only that, you could unlock voltages and perhaps, have more OC potential. Very cool stuff🔥

Hi, is there still the problem with disabled turbo boost after 528.xx driver ver?

Do you mean the extra 15W for a total of 165w as it is on X170KM-G? I think so, I never tried a higher driver although I can try it perhaps and get you back with the results. But it most likely never came back. Don't see a reason why it would come back.

[srs2236]

Maybe someone with P775TM1-G finds this useful. Just checked Intel ME software/driver and firmware. There are updates. You can update the firmware using command prompt and FWUpdLcl64 executable found in the System Tools -> FWUpdate -> WIN64 folder as admin and using this command line:

People with the Intel RAID EFI BIOS module: 18.31.3.5434 in their P775TM1-G BIOS can have updated Intel RST driver too:

 

This Set is dated 03/08/2023 and installs the Intel RST drivers v18.37.7.1013 WHQL resp. v18.7.7.1013 WHQL:

Hi! Just tested latest driver as of today 546.65 and the TDP slider is still locked.

[zex4]

Hey thanks for the interesting firmware updates 👍 

 

Also wanted to ask...wich heatsink you are using for your rtx 3080 ?🤔

 

I finally could buy a good priced rtx 3060 mxm in perfect condition but of course don't have any heatsink for it....

 

The aliexpress heatsink I have is only for 10/20 series sadly

 

But I would prefer separate heatsink If a could find gpu only heatsink for 30 series...

Hi!

 

I have an AliExpress heatsink which was compatible with 30 series.

[zex4]

Hey buddy 

Just wanted ask you how your machine is going until now...are you still happy with it or still have some problems so solve..actually also wanted to  ask @MiRaGe but mybe he will read this thread 😅

 

 

[zex4]

Why I am asking because I could finally find a good priced 3080 on ebay...also buyed i9 9900kf time ago but not installed yet because the i7 8700k and rtx 2060 was enough for now....Actually I wanted to buy a new gaming laptop with 13gen i7 and rtx 4000 series gpus but most of them unfortunately have fewer USB ports and no support for 2.5 HDD, not even the 17,18 inch ones and I love the 775 so much...they are really robust machines, and you can still get spare parts from Clevo directly...buyed new display cable 2 months ago 😅

[zex4]

From now I definitely want to keep my 775 and upgrade much as possible, that's why i wanted to get updates from you on how your 775 is doing😇
