    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.

    Lenovo Legion 5 Pro

    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..

    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.

    After more than five years with me, it was his time to go to notebook heaven. RIP, sweet prince. I have spare mobo, but I won't use RTX this time, I will go back to P5000. I will do cable mod and BIOS thing, even one more DIY heatsink work. So everyone else could go my way and make his laptop better. Thank you loopster, and everyone, for support. Someday I will mod some RTX GPU, again..

    With delided CPU and Honeywell PTM it is very nice ! I use it for almost month and it is going strong! Quadro P5000 110W in this moment, I sometimes use FN+1 Turbo fan profile, but that happened in few very CPU heavy scenarios. I plan to use RTX 5000 from HP here. Teaching old dog new tricks is cool, now it boots from NVME, too 🙂

    BIOS with most interesting options unlocked, flash and use on your own responsibility. Works on P750ZM/P751ZM. Should work on P770ZM too, but there will be bad motherboard name in bios. I have also inserted NVMe driver for booting https://drive.google.com/file/d/16dmPgyPI9r_iNOEKTia0ThhHDYrvZygf/view?usp=sharing If I will have some more free time, I would mod my Quadro GPU ID so I would not need to use NVClean. And add updated Xeon 1285L v4 microcode.

    (In professor's voice from Futurama) Bad news everyone, my 8570W lately started to malfunction. Motherboard needs to be repaired, I checked CPU and RTX GPU separately, and they are okay, but in my modded 8570w I'm getting black screen freezes when CPU uses more power. Swapping in weak CPU works, but that is not point. So hold your fingers crossed for me making my PC alive again, thanks.

    Max native speed is 2133mhz DDR3 Kingstone HyperX Impact. HP Bios is encrypted and locked, undervolt is not possible on this generation.
  12. GuitarG
    I think you could pop RTX 3080 there. 16GB 150W Super version.
  13. GuitarG
    How do you screw this 3080 to Clevo motherboard ? Aren't those holes offset or I missed something ? If someone could upload some photos of that mod it would be great ! EDIT: Ok, after little research I found answer, TM1 have offset mounts for both GTX and RTX cards. Still, I want to use it in older ZM EDIT2: All clear, no way installing RTX card in ZM. No place for board because of chassis structure. Unfortunatelly.

    It could be very simple repair, like one damaged transistor, bios flash. Or more complicated stuff like damaged PCH or KBC. Only board level repair specialist can help, there is too much possibilites without having damaged board on table. Mine I bought very cheap, 30$ without PSU (I had one already), changed PCH myself (10$), one transistor (less than 1$) and it works. And I don't think PCH was damaged, but you can't be sure it's not damaged until you change it. Seller also took out his 4790K and 980M, sold those separately.
  15. GuitarG
    Do you mean CPU and GPU works in different laptop ? Do your P751zm have LED blinking codes ? Fans runs 100% ?
  16. GuitarG
    Xeon E3 1285L V4 (i7 5775C equivalent) working ! I tossed a coin and I'm ordering RTX 3080 GPU =] I will show pictures later and I will share unlocked BIOS file.
  17. GuitarG
    Sure, I do! I made custom CAD heatsink already, but I have big design choices right now. I am deciding if I would want to use vapor chamber in my 8570w. I'm looking for other RTX GPU for my P750ZM, too 😄
  18. GuitarG
    It is exactly like you think! I think price is okay, you will end learning few things on way. I bought GTX980 with visibly overheated PCB where damaged mosfet was, it also was shorted and turned overcurrent protection on PSU. I regret not taking second one - guy sold 2 of them. I got it for 10 $. I also added 3 more mosfet and caps, so it would not be damaged in same way. It is always a gamble, sometimes core, vram or buck converter may be damaged. Remember to trust your logic more than multimeter - Quadro P5200 I bought had whooping 0,1 ohm resistance on VCORE ! It worked no problem for years and now somebody else uses it (reference- working silicon I tested always had at least 2 ohms when tested). From GPU die point of view there is no difference if it was 12V or 20V - any overvoltage is going to kill it succesfully. So don't count on common sense in electronics repair 🙂

    Xeons work no problem at all, right now I'm using E3-1241 v3, I am waiting for xeon e3 1285l v4 with eDRAM. That is 5th gen Broadwell CPU. With unlocked BIOS I can check if that L4 cache works. Similar to xeon is i7 5775c (difference being unlocked multiplier). I am very curious how it will behave together with my Quadro RTX 5000 from HP, 2133mhz RAM and every "hack" available (like REBAR, above 4G decoding, undervolt, etc.). Most importanly, I would allow me to check if recent GPUs would work in dGPU only notebook. If not, then I would look for way to make it work 🙂
  20. GuitarG
    Okay, I made it myself anyway, (like classic says - "I will go hack my own BIOS with blackjack and hookers!") here is why I wanted: Boots, works. I can undervolt CPU from BIOS, set fan thermal behavior, overclock RAM (make it use XMP). Now I also need to clean up some options (not needed). Even made custom boot splash with my cat for fun. Time to buy Ampere RTX I guess ? Or maybe Intel dGPU ?

    Hi Clevo people ! I have acquired Clevo P751ZM recently (1 means EU version, 0 is for rest of world - minor difference in grill looks), repaired it and now it's rockin' nice Xeon CPU together with P5000 Quadro. I had found clevo repository with newest factory BIOS, but I'm looking for modded one. Can anybody help me with file ? 🙂 I think P770ZM is also compatible. And if someone would have keyboard for sale would be awesome, too! Thanks!
  22. GuitarG
    Not needed anymore, I ended up repairing board myself, changed PCH and one small IC, works great. Closed.
  23. GuitarG
    Check HDD/SSD health, things you described sometimes are sign of incoming storage failure.

    Hi! Looking for above, I'm looking for working motherboard. I'm located in Europe. I have chassis already, but with not working motherboard (damaged PCH).
  25. GuitarG
    Where are you from ? I may try to help you both with capacitor and cpu pin. About 4xxx series not needing 4G, where from you got info ? Did anyone already succeed with 3xxx series ? Previously I thought for those to work it needs only correct vBIOS, but I saw many post with people trying make it work, but always they had some kinds of driver errors, etc. I myself do not tried it. In my opinion, for above Turing cards to work with our motherboards we need few things, firstly correct settings in UEFI, correct INF file moded, at least Ivy Bridge chipsets, appropriate hardware signals needed for card to POST.. and my bet is to use dGPU only laptops. Every laptop OEM have very different approach to how internal screen works with both iGPU and dGPU. And it also depends how oem had written motherboard software, which may be another obstacle. I looked at PC game benchmarks, 3770k with rtx 4080 for example, downloaded bios update file, checked it with UefiTool, voila! Firmware from 2014 have 4G Decoding option.
