It would also be conceivable to make a version for an MXM port, but then a desktop card still wouldn't fit in the P775! However, the power supply I developed would fit in the SSD slot. The problem then would be the space for the GFX! Link to comment Share on other sites More sharing options...
SuperMG Posted September 10 Share Posted September 10 (edited) @Developer79 Hello are pins 278 and 280 mandatory like pin 240 and 242? Or should they always pass to the GPU? It's just one line with some capacitors on the way. Some MXM cards don't have them visible, maybe it's inside the multi-layered PCB.

You can always tell by the vias! Sure, lines are often routed directly onto inner layers. My board has 12 layers and it was already very tight. It all resulted from the resulting geometry of the board!!! Link to comment Share on other sites More sharing options...

I just wanted to say that you can see it when you look at Port! But you need good eyesight. Anyway, we don't need to fill the thread with too much information like that. I think for most people, it's the results that count. Link to comment Share on other sites More sharing options...
zex4 Posted September 16 Share Posted September 16 does someone have full drivers pack for the p870tm1 ? i cant find it on google anymore...there was two clevo drivers archive but both are down its seems ;( Link to comment Share on other sites More sharing options...

Developer79 Posted October 12 Share Posted October 12 Hello everyone, If anyone needs a holder for the RTX10/20/30 in the P870DMG, I have some made of steel! This allows you to install Clevo's MXM cards from the GTX10xx / RTX20xx / RTX20xx Super / RTX30xx series in the P870DMG! 1 Link to comment Share on other sites More sharing options...
Developer79 Posted October 28 Share Posted October 28 Hello, I have slightly modified my new P870DMG graphics card holder(stainless steel). This allows the GTX10xx/RTX20xx/RTX20xxSuper/RTX30xx MXM series from Clevo to fit better. The standard MXM cards from other manufacturers will also fit into the P870DMG. That means the RTX40xx/RTX50xx series! With the latter, it may take a little more effort to get them to run properly in the P870DMG! 1 1 Link to comment Share on other sites More sharing options...

Developer79 Posted Friday at 06:38 PM Share Posted Friday at 06:38 PM 25 minutes ago, Maro97 said: and you don't need the two gpu fans ? right ? It depends on the cooling! Water cooling is quicker to implement. A vapor chamber must be well made. Link to comment Share on other sites More sharing options...

That's no problem, there is a desktop card that you can choose and that fits well. The RTX5070 Ti and RTX 5080 are quite suitable. The RTX5070Ti is the best choice and offers a good compromise between gaming and power consumption! Link to comment Share on other sites More sharing options...

Developer79 Posted yesterday at 11:23 AM Share Posted yesterday at 11:23 AM 15 hours ago, Maro97 said: How did you cool the RTX 5070 Ti graphics card? And which company manufactured the card? Since several cards are compatible and I have only tested one prototype, I used standard cooling. First, I would need to find a good card or make a list. Then I can implement water cooling. That shouldn't be too difficult, because in the end it's just small copper heat sinks for GPU dies and MOSFETs. First, the new MXM adapter boards are ready and need to be tested after assembly. For me, the problem was resolution and frequency. Hopefully, that will be fixed soon. If everything works, my MXM adapter will be fully compatible with the P870xx!!! I also modified the power board a bit to achieve good performance in the P870xx. Many Nvidia, AMD, and Intel cards will then work! Besides, I am a ONE-MAN development team, and you need money for that too! I don't have much of that at the moment. That's the status! 1 Link to comment Share on other sites More sharing options...
Maro97 Posted yesterday at 08:15 PM Share Posted yesterday at 08:15 PM How much performance can i get when make a shunt mod for my clevo rtx 3080 mxm ? And how much TDP can i get more than 150w ? Link to comment Share on other sites More sharing options...
Scruffy Posted yesterday at 10:24 PM Share Posted yesterday at 10:24 PM most of the shunt gpu mod killed the bga in long term use. i wouldnt do that. u can try oc the gpu core based on the optimal vcore. it's much better to have a stable notebook then a faster one 🙂 Link to comment Share on other sites More sharing options...

And don’t forget the gpu vbios can handel 165w with Nvidia old drivers Link to comment Share on other sites More sharing options...

However, you did an amazing job and completed the most difficult part, which is transferring the signal and data from the GPU to the internal screen using an MXM adapter. This is truly the hardest part of the process. You are a legend, and you have all my respect and appreciation, my friend, for this great effort. I hope to be one of the first buyers of this project once it’s completed Link to comment Share on other sites More sharing options...
Scruffy Posted 13 hours ago Share Posted 13 hours ago problem with shunt mod is not temperature related. it give the gpu more current , regardless of the manufacturer standard. for silicon propriety, more current u give in long term, more it will need in the future. for esample, now gpu will need 0,8volt 100A. after 2 years it will need 0,82volt and 102A. with shunt mod u give gpu 1.1volt and 120A. after 2 year it will need to stay stable at same clock with first shunt mod install 1,2volt and 130A. after a while the bga will not work even with much more overvolting. there are a lots of discussion and video on yt about shunt mod vga failure.
