This is my last benchmark at room temperature(only air cooling): P870TM / RTX 3080 / 9900KS / UHD 120Hz

Hello, regarding G-Sync. It is definitely not a hardware problem! It needs a bios update! Does your modded Bios everything works as before!?

I used 2x RTX2080 in the P870TM. It worked well. I tried all this almost 2 years ago. This is so-called SEMI-SLI. In games it also works, but you don't have extreme advantages. I can send a benchmark from 3D MArk later.

I wanted to say, let's see how the board works in normal operation:-)...I have not tested it yet, as I said!

Ok!!....Let's see what possibilities the board offers!

I have also just another version to test there. But I have not yet come to....This is currently a development version!

I have today my own modified bios(P870TM) extended with RTX support! Many thanks to ViktorV and Dsanke! I tried it with RTX 3070 and RTX 3080, it works fine.....

You can optimize something in the Bios! In the P870TM I keep quite often 5.2 Ghz1 The loss reading of 143 W tremendous! The heatsink is certainly not designed for this. Perhaps you can still accommodate a few heatpipes and increase the contact pressure a bit...

Also very good! But with a P775TM! Still nice...I put no value on optimal exploitation, but only Reliable good running:-)

I can confirm ViktorV results! I also knew it for a long time! 8 lanes have no loss as a result! Even compared to the latest generations...Also the temperatures can keep up with new systems without problems..My system: P870TM / RTX 3080 / 9900KS...See photo:

I have already tried this! Simply porting does not work so well...There are other things to manipulate! 2nd thing: The p870xx has basically only 8 lanes available. The bios does not change this! The bios is set to automatic detection. It will always find 16 lanes on the P775xx and on all P870xx always 8 lanes per MXM port....

Here...

I use the P870tm like you! Of course the fans must run, otherwise the heat will be too much! There is no other way in an air cooling system...

Here is a picture of the internals!

I'll get back to you later....

I don't use water cooling, just the big vapour chamber! Of course, the power dissipation must be transported away quickly. Only with the Vapour one reaches the highest power dissipation! I can gladly make photos later if that is desired....

No, I do not use a refrigerator, nor water cooling. I use the large vapour chamber! I can gladly make a photo if that is desired!

The temperatures seem very high to me under full load. At idle, the temperatures are like mine! I have under full load 50 - 52 degrees over hours with the RTX 3070...
