You don't have to have the copper heatsink. There are also adapters to continue using the original heatsink. The temperatures are at full load with me between 55-60 degrees with the air cooling and RTX3080. See pictures in the thread. I think this cooling performance can be seen:-)

You need a RAM bar that supports the XMP profile, that's why there are no timing values in the bios! On occasion I'll send you a picture of a compatible Ram!

I don't know why most people are so surprised when comparing the RTX3080MXM with the RTX4080 4090 laptop! It has always been the case that the laptop versions are somewhat weaker than the desktop versions in the same generation. The performance values of the RTX4080 4090 laptop are also electrically reduced compared to the desktop version. Then there is the influence that they are no longer MXM laptops. With an MXM card, the electrical influence is separated to a port with a certain distance to the rest. The electromagnetic influence is then lower.

I did another test with Guardians of the Galaxy. I found well comprehensible settings at Computerbase. Comparing the P870TM / RTX 3080 with the RTX 4080 4090 laptop now shows that the RTX3080 performs on the level of an RTX4080. In both settings with ray tracing and without, the whole thing is as just described. The RTX3080 is about as fast as the RTX4080. The RTX4090 is always a bit faster in the game.

I have to agree with him there! That with the programmer you must also consider certain things. But just try it out!

I have a comparison here between Computerbase and my tests on Cyberpunk. The exact settings are documented here. Take a look at the amazing results! The P870TM / RTX3080 / 9900KS performs better in raytracing than without! With raytracing, the P870TM / RTX3080 is almost 20 FPS faster than an RTX4090 and without it is about the same, maybe about 5FPS slower!

Yes, I agree that the benchmarks are somewhat changed so that the new laptops RTX40xx looks good! Anyway, that's my experience in measurements:-) You must also remember that an MXM card would generate more reading. But because everything is basically soldered there is more interference and influence!

Here is another test from someone independent on Youtube. You can see all the settings and apply them exactly the same way. Gaming performance is identical for the comparison and the P870TM / RTX3080 / 9900KS performs equally fast to the RTX4080 at 175W / Intel Core i9-13900HX!!!! The comparisons rather show the picture, the RTX4080 performs on the old RTX3080 MXM level! The RTX4090 laptop is slightly faster than a RTX3080 MXM! With DLSS 3.0 comes even more distortion to it and brings only in the supported games extra performance. All old games remain rather the same speed compared to the RTX 3080 MXM!

Yes, that's a problem with availability! Corona has also increased inflation and with it everything old prices! The days of cheap are over and you really have to spend more than before! With appropriate adapters it is possible to make the Vapourchamber compatible with the RTX30xx series...

Here is a quick test comparing Notebookcheck and Cyberpunk: However, I don't know how Notebookcheck comes up with this average value!!!! They don't give exact test conditions!!!! I think it's a bit dishonest to people not to reveal exact test details!!! I can only run the standard benchmark myself and compare like this. I think an average of 5 FPS slower with an RTX4080 175W is not bad, if the test conditions were the same!!!

Hi, this is just one example laptop of many! I test all kinds of laptops against each other! All the pictures I have shown are all different laptops with different performance classes. Unfortunately you can find little well documented test on Youtube on the new RTX4080/90 laptops. Can I also understand, they want to sell the new Lapotps!!! Even at Notebookcheck.com, some results can be poorly understood! In any case, the exact information is not always made or sometimes you have to rely on the information given! Often you also do not know in which scene the values were determined! I always try to find good comparisons, which you can understand yourself. But that is often difficult, because the testers reveal all the details. Only in Youtube videos you can understand well! Greetz:-)

Hi, you can use a modded bios from Dsanke or Prema made something for it in the past! But basically the original bios is good enough and the RTX30xx series runs without problems with this bios. I do not know why most people think you need a modified bios for the RTX30xx series!:-) Now you just need to modify the hardware accordingly. so the heatsinks etc...My heatsinks reach 53 degrees in full load and highest performance with RTX3080 in most games. The Vapourchamber offers the best air cooling. The RTX3070 in P870TM generate 50 Degree at full Load gaming performance... You can also see in my last test in comparison with the RTX4080/4090 that the RTX3080 is partly faster! I don't know why people want to get the latest laptops! My P870TM is in UHD 120/144 RTX 3080 / 9900KS still faster in pure gaming performance than latest Lapops:-) Look in the main post of ViktorV P870tm. There you can find the gaming test Greetz

Ok, I understand!:-) These are possibilities, yes!

What exactly do you mean?

yes, that's exactly how it is! And with hardware mods the 10th gen notebook. See VictorV Mods. But that only works because the electrical phases of the different generations are the same. Otherwise you would need a new motherboard with the appropriate multiphase design...

I can repeat it again with pleasure, no matter if Prema or Dsanke Bios, for the operation of RTx30xx series it is not necessary to have a modified Bios on the laptop. On both P870xx and P775xx laptops only "Unknow" card appears in the bios menu and the rest goes normally. When installing the driver, you only have to do a small step more. It depends on what drivers you install. I have been using only desktop drivers for years. I recently installed the latest 535.98, and even with Dsanke Bios a clean installation is only possible with driver deactivation. That is my experience. So it doesn't matter how you do it, from my point of view, the driver installation works either way in the same time frame!...I don't know why people always think it can't be done 🙂

Yes, most think it's mandatory to have a Dsanke BIOS for the RTX30xx series, no it's not! It's nice to have that, but you're not allowed to!

I can understand your solution and the opposition you have! Yes, in fact you have to have a deeper understanding of technology and physics to realize such solutions as mine. I am actually engineer or physicist but also always interested human being and Hobbyist! You also need CAD experience for such solutions if you develop everything yourself. I had the idea for the solution some years ago. Now everything is already developed in the 2nd version and I just have the boards manufactured. You also have to think about how to supply a desktop graphics card in the notebook with voltage if you do everything internally, etc.! The routing of PCie or Hdmi or Displayport you have to consider everything:-)

My own results in comparisons of P870TM / RTX3080 / 9900KS vs latest laptop with RTX 4080 show that an MXM RTX 3080 laptop is as fast, mostly faster, than an RTX4080 soldered laptop, and regardless of resolution. I tested from FHD to UHD. Here 2 Examples with Horizon and Metro Exodus!!!

Hi, again basically. You don't necessarily need a Dsanke bios to upgrade to RTX30xx series. Everything works without!!! The Dsanke only enables the detection of the RTX30xx series in the system bios and support as a system-associated graphics card! That's all. As I said, but basically the Dsanke bios does not have to be on the computer!!! There is no RTX3090 from clevo! It only goes up to the RTX3080 series in MXM format! Then it's over. Yes, the P870xx is one of the best laptops ever in my opinion. My current project goes worldwide only with the machine no other laptop offers so much scope for upgrades!... Also, my tests comparing it to the latest RTX4080 generation show that the P870 with RTX3080 is still faster! Only the RTX4090 series is slightly faster and depends on config of the laptop! There you see again the advertising that blinds people!:-) Greetz:-)

Basically, you don't need a Dsanke bios for the P870xx. The RTX30xx series also works with the normal bios, you just have to do a few more steps during the driver installation.

Good to hear! I have solved my solution for the screen as original internally. Thus, the desktop cards are connected directly via the internal display.

The Vbios of the desktop cards does not include an MXM header for the system bios(See MXM software spec). For these laptops, the manufacturer(Clevo) only assumes MXM modules and desktop was never considered or limited:-) Therefore the system bios still recognizes the card as a problem!

This is an interesting solution, but it is a pity that there is no intere solution:-) In my considerations, I always come to the conclusion that the P870xx offers the best possibilities. A laptop should still offer the mobile possibilities! With me now also x16 lanes works and I can also install drivers without driver deactivation:-)
