    It is same die as 980, Maxwell gen. So it should work with LVDS display. With Maxwell I had no problem with LVDS screen. I used 980 and checked M3000M. I had a lot problem to make them work with Dreamcolor, though. I used specific driver version, which still supported 10 bit output.

    CPU is Achilles' heel in this laptop, 3940 will give you nice performance. It is most efficient 3rd gen mobile CPU. Remember to use PTM7950. The newer GPU you use, the better it will work. 965 may cost more than something better and modern. Remember what panel you use, though. 980 and 965 are last ones working with "normal" LCD, newer ones need modified LCD cable and eDP panel or Dreamcolor assembly. I recommend first option more, cheaper and better. I bought few months ago P5000 for like 100$. EDIT: About vbios, it is lottery. With Turing gen, every Vbios worked for me. With Pascal (Quadro P5200) only few of them allowed me to boot. On Maxwell (GTX980) MSI vbios worked correctly, others didn't. Seems like modern GPUs are more compatible. And try to use NVclean, download newest driver for your gpu from nvidia site and load it with nvclean. On linux you don't have to mod drivers anymore btw. That large pile of heatsink are just leftover from my work and project. I repair a lot of damaged notebooks and sell them. And sometimes I bought a lot of heatsinks for 5$ each. That pile is about 3 years of auctions 😃 Anyway, I found another 8570w auction, wish me luck so I grab it cheapest I can! = ] my modded cable awaits its glory! And remember when I had Clevo ? Now I'm trying to grab damaged Alienware M17x R4 and try it out.

    Quadro T1000/T2000 or any RTX 3000-5000 will work. Tried few vBIOS on mine, all worked with differences being what ports it outputs, for ex. some vBIOS didn't worked with my Displayport. They also different with TDP, Mhz min and max parameters. I would love to borrow Ampere gen card and check if it would work.
  4. GuitarG
    Yes, check out my HP 8570w thread or Khenglish's one with his Clevo =) we both made custom coolers

    Hi folks! I mapped out connections needed to conversion, everything ready to go. I have 4K IPS eDP screen for testing ready. Unfortunately, I have to look for spare 8570W to test my modded cable. Cheapest in my region is about 200$ sadly. So Im waiting for cheapest possible =] If it will work and don't burn anything, I will show connections schematic here! Or maybe someone has one in working condition for sale (or science!) ? Unfortunately, without Intel GPU it's not possible to use coreboot together with windows. It's linux only

    Most important ? Use low temp. soldering paste - lowest is Sn42/Bi58 Melting Point: 139°С. (I'm pretty sure manufacturers use this exact compound). Also best to use something like oven with temp. control - don't exceed 140-145 celsius degrees for both heatsink dissasembly and reassembly. And oven is best because of heatsink properties, you need to saturate (heat) every heatsink part for solder to melt and not damage fragile heatpipes. Best way to clean old solder or prepare surface for soldering is to sand down using sand paper or flat metal file and wipe with isopropyl alcohol on tissue. Make sure surfaces are flat as possible for best contact between surfaces. Solder is for mitigating air gaps and holding both surfaces.

    Heh, thanks ppl =] that's really nice to hear. Unlocking iGPU is a no-no, mxm gpu is directly connected to internal display and external outputs. Schematics says intel gpu is not connected anywhere. And iGPU is turned off in chipset configuration, too. But ! having such setups makes it more compatible and not lose about 10-20% of power (like in optimus scenarios). So best way is to modify original LVDS cable and make it eDP. If I manage to save some money for another (haha) spare 8570w and manage hands health related problems, I will make tutorial of it and present it =} And DDR3 just works with such SPDs, because those are HyperX Impact 2133mhz ones. They are more rare than 100$ laying on ground, though. You can use cheaper 1866 mhz, those are easier to find. They work out of box. Factory bios is locked in this regard, coreboot allows to overclock RAM (some people use that option in thinkpad ivy bridge gen). By the way, I have succeeded with compiling coreboot with ReBAR and Above 4G options, it just worked. Unfortunately I don't have Ampere card or Intel Arc to test it.. but I think it would just work. At least I hadn't encountered any problem or bug people said when they used DXE rebar driver.

    Well, this custom coreboot need more polish, but seems it works !

    Hi, in fact I did same, bought BB09 not holding charge. I had to wake it up using original HP charger (you have AC input on battery, so you don't need to connect to laptop to charge it). It held charge for almost hour, but near 10% backlight started flickering - meaning battery needs new blood li-ion cells. I discarded guts of that slice battery and made it laptop stand so I can use it laying on carpet or bed. I think yours need longer time on HP charger

    I use DC screen, meaning it's LVDS driven by EDP-to-LVDS board. That board is connected by EDP from mobo. On mobo there is 50 pin connector, housing both LVDS and EDP signals. Which one are used is determined by GPU used. About project I think that CPU is defective, every RAM I tested threw error in memtest, meaning RAM controller in CPU is shot. And I don't see any good CPU for sale, even on marketplace....
  11. GuitarG
    I don't think it is worth with such old CPU. It compiled shaders for Monster Hunter Wilds for 6 hours (first start). Right now I have faulty RAM sticks to troubleshoot and I'm getting tired. 1. Yes 2. Yes, I planted DC screen from 8560W to mine 8570W. 3.Never used Mxx cards, but in that case I would use external monitor untill installing drivers.

    Pretty simple, test using game/program taking between 90 to 100% usage of GPU, check GPU core temp with Msi Afterburner and if core temp is lower than 90 celsius, any sudden shutdown means power delivery overheat. Not all GPUs, especially those in laptop, lets you check those. I checked height of original heatsink and compared that to mine.

    It was windows update that corrupted my me region along with bios .... I used windows 10 ssd for using nvflashk for vBIOS flash (it was faster than learning how to do same in ubuntu), used it for like 4 minutes, after successful flash I restarted... "WAIT FOR UPDATES BEING DONE" During those few seconds before I pull plug, it made so much destruction. I had to use different flash chip and search for original bios dump!! ME region destroyed laptop entered manufacture mode! And I used Windows Update blocker on that drive (it was "emergency safe win10" external ssd). Now it is working again. But let it be warning for everyone =] TL;DR - using Win10 for vBIOS flash broke my laptop BIOS. GPU is fine

    Tried different distros, finally stayed on one seemed most known to me (I had experience since version 8.04 was considered new). I always had given up on learning and using it as daily driver, now I sometimes have some problems, but lefty loosy - righty tighty and still not going back anymore to Windows.. especially after last 3 buggy reinstalls in 2 weeks.. EDIT: It is Ubuntu, 24.10 And Arch also known as SteamOS on my SD.

    It could be sign of not compatible GPU core temperature sensor. Laptop enters panic mode, fans goes with max speed and turns off after minute. There was one guy, to whom I sold my P5200, that described problem (here on forum) and solved it. Then P5200 worked flawless with his Clevo. You have to look for throttle reason (in Throttle stop) and I suspect it could be power limit (because of not compatible temp sensor). PCI gen 2 wouldn't limit wattage given to GPU
