    As good as it can get now, benchmarks after "another patch":

    True, best and very costly way, I got quoted almost 150$ for one ! And then is even bigger problem, heatpipes. It wasnt possible for me to set them up like I imagined. That is because of laptop non-negotiable dimensions like battery or RAM slots. Sadly. I circled two troublesome VRM's protrusions, depth for coil cooling is also different Now hardest part comes - to solder it. And if works like intended - paint job.

    Thanks ! Still ironing heatsink out, I forgot about different thermal pads dimensions. It shame I don't have some nice CNC machine. I played for a while and temps were up to 90C turbo CPU and GPU 70-80C depending on load. VRM or VRAM overheated once after 30 minutes, so I'm making corrections What PCB do you have in mind ? If first photo, it is donor board+case cutted up for aligning heatsink with highest homemade precision 🙂 I use damaged CPU and GPU board, screw heatsink on and clamp heatpipes.
  4. GuitarG
    Secret for success is to align first, then push harder second time. After baking like this first, then its screwed harder and heatsink only for max efficiency Now time for final tests, touch and black paint

    I have same model & revision, so that one seems more safe choice. Differences are much more stable behavior, hardware bugs fixed. Using my P5200 as example, in rev A that card would burn its power delivery if used with +90W bios. With rev D it could use 110W for long time with no problem. Model and revision says about board, not core used. It is true about perfomance loss in SG, up to 15%. For that alienware it seems you may have two options: 1. two board versions, one for edp other for lvds 2. one board version using single connector and two different lcd cables (like my HP). With eDP you would have much more LCD panels to choose from (LVDS is on its last breath). DP signals are different than embededd DP, eDP drives with PWM internal LCD brightness, use of closed-lid hall effect swtich for turning it off when closed, most important ones.

    Quadro cards are (or at least were) a lot more tested for high quality and reliability. They are made from better silicon dies than consumer grade chips. My previous Quadro P5200 had almost a non existent resistance on VCore, it was much more efficient than typical GPU. For your question, it depends on how your laptop generate graphical output. There are generally 2 ways, using internal GPU as internal display driver or dedicated GPU only. With first one you can safely assume most GPUs will work. With second options, you have to be careful. Mxm card have to use correct vbios and drive internal display. On schematic you can read that laptop can output in serveral ways, you can disable Intel iGPU and use eDP-dGPU only. Quality Samples may don't have *final* specs - in worst case you may have downclocked GPU, no Nvidia PhysX, Raytracing etc. It depends

    HP one is Quality Sample, because it is "Model 0MB" and additionaly first Rev (A). HP Quadro RTX surely supports eDP, though. I'm using one taken from Zbook 17 G6 in my 8570W. Remember that you have a lot of modification to do with it. X clamp is 5mm offset, so are two mounting points too. As for green RTX I don't know anything I could help with.
  9. GuitarG
    New board, new approach. This time results satisfy me more Soldered two pieces of metal to original mounting points, holds very hard and screws RTX very nicely. Now I have to sort, dissasembly and test a lot of copper pipes. And lastly, solder whole heatsink assembly

    Interesting setup spotted in Asus laptop - third fan. It is funny to see similar approach to temperature problem as my second fan blowing additional air to GPU cooler

    Okay, now I'm testing it, but it seems my 3940XM died. I changed CPU to something I had spare sitting in my CPU storage bin and it works, for now. I wanted to buy Legion 5 Pro for 1800$ with 4070, but I was hesitating, fortunately. I will buy 3840QM this time, 3940XM died not because of mobo or not having enough cooling, but because I bought it from Chinese shop and it had factory defect seen under some angles with direct light on it. Old board should be working, I will test it too sometime. Nowadays throwing 6000$ won't get you same quality as back in the days. I am happy to continue my thread! Long live the fighters ! ^_^ EDIT: Below you can see silicon die from naked eye view and under 4x microscope. It may be uneven heatsink or CPU that didn't pass QC in factory and been sold in gray market. It had two big circles on it from start and I had feeling it could die someday.

    GuitarG replied to Linux's topic in Lenovo

    How do you set up games ? Do you use Lutris ? How can you monitor temps in Ubuntu? It there some easy alternative to windows hwmonitor ?

    I think you could swap those MOSFETs on MXM boards for new ones and add those 3 missing. It should make it work. They may be unstable under higher loads, they endured up to 40A of current for long time. This should fix your GPU. vBIOS is totally fine, you don't have to change it. I wanted to see real photos of your mxm board to look if there is any discolour on PCB, not to know what model it is 🙂

    Well, my spare 8570W suddenly doesn't work, too. It does sometimes turn on, boots into windows, but mostly it is not booting and sometimes bluescreen occurs "ACPI Error". I never had seen such problem, it seems to me I may have curse on me, because even my third laptop, clevo I used recently, have "died". Three laptops in such short notice.. Damn. I have no other logic explanation for these issues, despite being very good at electronics and modding.. I will give myself some time to rest to come back later. After I visit some voodoo doctor..
  15. GuitarG
    Your Gtx 970 trips overcurrent protection, do you have photo of MXM board maybe ? Or it may be just wrong vBios. I used 980 with 100w TDP for a long time in 8570w, MSI vBIOS.
