I'm following your project, although at one time I chose dell m4800 and old alienware as platforms for experimentation). Could you please provide a link regarding possible support for 4G Decoding and ReBar in Coreboot? Because it is a prerequisite to upgrade mxm gpu to Ampere generation. Here you go: https://www.phoronix.com/news/Coreboot-Resizable-BAR EDIT: Haswell may have problem with Coreboot because thanks to Intel (TM) Boot Guard. Your mileage may vary. I had already tested this alternative BIOS simplifed version, and it works! Now I need to compile updated version with corrected bugs and graphical interface. Never though I would be making my own bios hahaha! Link to comment Share on other sites More sharing options...

GuitarG Posted November 17, 2024 Author Share Posted November 17, 2024 Adapter for faster debuging on spare 8570w, I will make same later for main one. I plan to make mini board with dual bios, one coreboot and second will be original hp one. I can test much faster now. Right now I can boot linux, but I have no visible BIOS and fans don't work on my compiled coreboot. BTW, did you know different flash IC's loads time is varies? You can tell by how long it takes from power button to visible BIOS logo. Macronix is x2 faster than original winbond on my main notebook 🙂 On left main one vs test on right. Both with latest updated firmware. Coreboot is even faster (but I don't have video for now) D2P0Obbj.mp4 1 Link to comment Share on other sites More sharing options...
GuitarG Posted January 28 Author Share Posted January 28 (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. 1 1 Link to comment Share on other sites More sharing options...
loopster Posted January 29 Share Posted January 29 @GuitarG In case you can't fix it, pm me, I got a spare one lying around which I am willing to donate for free to a mad lad for the good cause. Postage costs only. 1 Link to comment Share on other sites More sharing options...
GuitarG Posted January 31 Author Share Posted January 31 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.. 1 Link to comment Share on other sites More sharing options...
GuitarG Posted February 7 Author Share Posted February 7 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..

GuitarG Posted February 11 Author Share Posted February 11 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.

martin778 Posted February 11 Share Posted February 11 To be fair in the past we had CPU's running with more damage than that. If the silicon is damaged, the CPU should be either working or dead, not degrading over time. Link to comment Share on other sites More sharing options...
GuitarG Posted February 13 Author Share Posted February 13 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 Link to comment Share on other sites More sharing options...
martin778 Posted February 15 Share Posted February 15 Not a fan of such solution (pun intended) - gaming laptops in general have a short lifecycle and finding a proprietary replacement fan will be a major PITA. At least ASUS used to apply LM from factory so you'd never have to pull the heatsink assembly apart. 1 Link to comment Share on other sites More sharing options...
GuitarG Posted February 18 Author Share Posted February 18 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 Link to comment Share on other sites More sharing options...

GuitarG Posted March 1 Author Share Posted March 1 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 1 Link to comment Share on other sites More sharing options...

And what is that PCB doing in the corner of the heatsink? Looking forward to see the final build fully painted! Link to comment Share on other sites More sharing options...

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. 1 Link to comment Share on other sites More sharing options...

What corrections are you referring to? In my opinion, the most suitable solution would have been a custom-made heatsink, preferably copper. However, the biggest downside is that obtaining one is much more challenging. As for using the pieces of the donor board, that’s impressive! I never thought of that 🧐 I look forward to new updates from you) Link to comment Share on other sites More sharing options...
