GuitarG

Hi everyone ! Recently I won not working Clevo P170SM-A for very cheap, I repaired it (it was just one small bad capacitor) and checked out whole system - I never saw Clevo in my life. Replaced CPU for i7 4910MQ, changed TIM to honeywell for CPU and for GPU (GTX 870). I got heavily inspired by it, I liked disconnected CPU and GPU cooling system with two big independent fans. I was tempted to try out RTX in it, but it would need case mod, because of card protrusions (Deja vu!). I think it would work no problem even without modded BIOS (that's because optimus, Pascal and above works even with LVDS signal lcd). Btw, power supply for clevo is totally same model for 8570w/8770w with just different connector. CPU runs unchained, temps are under 70 degrees under heaviest loads, GPU gets up to 80-81 celsius with 100W load to core + a bit more to memory. It has optimus (which may be problematic - some retro games won't scale to fullscreen or some games have problems running at all / running on dGPU) vs. on HP only dGPU no problems at all. Still, I would like to test some powerful rtx card in it (like standard mxm aetina, I saw one rtx 3000 for 300$) so I will have reference point. Clevo seems to make best cooling system in those desktop replacements class laptops, but cuts cost everywhere else (touchpad, hinges, case, LCD, etc.). And whoever designed that keyboard layout, I hate him .. Anyway.. heeeere Cleeevo! Above temps are not even best ones - I can make fans work 100% and it is even better (downside is ear bleed from dual whine). Sound quality in Clevo is also better - it uses Creative x-fi, it does have external amplifier so it's louder and better. So I think now it will be for the best to make two totally unconnected heatsinks. What do you think ? Would it be uncomfortable to have hot air blasting from both sides ? I think that one heatpipe is not enough for more that 50W of TDP. Even now while I restrict RTX to 50W maximum, it may overheat itself to 80 celsius. When I used p5200 with beefier cooler, one pipe was enough. But I would love more to have heatpipes being able to cooldown GPU in seconds, like in Clevo. I need your objective opinion, people ! 😃 I will need to make additional holes in case for second fan (more airflow, routing space for second heatsink). I though about modding fans mounting because original one restricts it (vs. 8770w ones). Spare 8570w in transit so I can safely try my modded original to eDP cable 🙂 and undervolt board. I am excited to see if my hack/mod works - Dreamcolor set is like unicorn (or Zod rune from Diablo2 - both fairy tales) these days. I will record another videos when after work with cooling. I will make few of them this time - one for general simple showcase, one for show off work done, dissasembly and reassembly of laptop and two last ones separately for pure benchmarks and gaming. I think one long video may be too boring, even for enthusiasts ! Idea: fan mounting metal sheet - I marked zones to cut for more airflow (so it more cold air and no more whining sound [because it *chokes* now]).

AX210 bluetooth working, just run 2 cables from BT connector (4 pin Data- and 3 pin Data+) to WLAN connector (38 pin Data+ and 36 Data-). Double check for shorts to ground or between them, use UV mask and voila! No more weak BT 4.2 and bad reception with BT earphones. Now works like modern laptop! 😄 I had also connected touchpad succesfully and fingerprint sensor. Touchpad connector and fingerprint soldered back, too. Changed Dreamcolor2 board from 8560w to zbook 17g2 blue one. Now I have correct calibrations profiles from factory! Perfect! White is white, black is black and good gamma now. i1 display pro from x-rite didn't work with board, though. Program found LCD but couldn't connect to profiles from DC board, I even tried different Windows and put original Quadro K1000M. Didn't worked. I saw in changelog there was compability with i1d3 xrite added, so maybe that one would work.. Aand lastly, LCD cable is still work in progress, same with copper heatsink. But I will deliver one day.. 😄

LCD cable conversion in progress, will show diagram and work later. I will change to 16 inch 16:10 display from Zbook Fury G9. I will use 30 pin connector (from random eDP cable) and use original lvds cable from 8570w. I have spare 8570W so I can test if it works safely =] I had also ordered colorimeter for Dreamcolor calibration, I wonder how it will look after! And compare to LCD from G9 🙂

Does M6800 have 50 pin LCD connector on motherboard with both edp and lvds ? Are there different versions of flex cable ? I heard someone said "edp mobo version" but you guys are more reliable I think 🙂

I saw this yesterday and now I want to buy M6800 so I can mod it and benchmark it hard, haha ^_^ I think with correct vbios it will work, for sure. Question is, can it be flashed under OS or only externally. What were your symptoms ?

Unfortunately, T1000 I ordered was bad, it needed vbios flash first, then it showed artifacts ;( Anyway, where did you looked for N19E heatsink ? I am located in Europe and nearest shop shipping to my country was.. Australia. HP parts page showed not available, quoted ~350$ for order.. Yes, RTX gen works nicely with Dell Precision M series I heard. Much better than Pascal quadros with API problem on windows, only recently solved.

With heating plate and hot air everything is possible 😄 It would be cool to replace mobile core with desktop one, like one guy did on NBR with 980. In China lately a lot of older GPU gets more memory upgrade, sometimes even up to 24GB I heard. Don't know about older, newer GPU needs correct strap resistors to set up memory vendor and capacity. Also force eDP output (and use mining GPUs with laptop). With steady hand and BGA soldering skill, every BGA CPU is socketed. ^_^ Beginning is harsh, with every try it get easier.

Yes, that HP model is very satysfying to open, I could try different MXM card but I don't have any at moment beside Quadro T1000. Biggest challenge using other cards is modding heatsink and mounting points on motherboard. That is G6. G5 is weird one, it have normal mount points, BUT it's graphics card does not have vBIOS chip on them. Means it may have *whitelist* of specific MXM cards (because main bios flash have only few gpu vbioses inside). I have no idea what could happen, when using external vbios, it may be programmed to look for vbios in different places - like embedded unix bootloader looking for "system" on lan port, emmc, spi rom, etc. As for mine, I plan to sell it after modyfing heatsink, I took rtx5000 with its heatsink block for my 8570w. So I will insert block from Zbook G2 🙂

Well, I solved problem with external graphics, just use 90.04.97.00.B5 MSI vBIOS and it will work. It's literally same amount of DP outputs, thermal management, etc. I think Dell's would also work, but none is on internet (from precision 7540/7740). I start to wonder why HP hardware don't go along with HP software haha 😄

Sure, 15 and 17 inch are like 99,5% same, biggest difference is in placement of components and PCB mask color. Only minor differences

Until now I failed to see power button on G9 and G10 - it is on keyboard. I though it's more less than 500$ laptop thing, to cheap out on extra work and costs, but on workstation it is outrage (dell precision in same boat). Little liquid spill and can't power laptop, in worst case bigger IC dies (kbc, chipset or whatever 3.3v keyboard button they connected directly to). Feel free to correct me if I'm wrong, but that made me not to buy any laptop as that Fury G9/G10 was my last hope to buy fast & durable mobile rig in future.

I will buy next 8570w for test purpose! I want to make 8560/8570w easier to mod for everyone! My plan is to make detailed instruction how to customize LCD cable for EDP screens. On board is 50 pin connector, both LVDS and eDP. It is possible to connect up to 4K screen in our machines 🙂 No need to look for expensive and rare DC assembly. I will test it myself if theory is right. I'm also slowly progressing as I'm having not much free time on hands, but definitely getting there. Progress ! (tell me "yes", please ^ _^) Aaaaand I have found another problem - I can't pinpoint exactly why RTX don't want to show on Displayport. First thing in head is to change daughterboard (there is IC for DP control in schematics) to other or try other cable. Didn't tried yet, and I have only DP to HDMI (worked with P5200) and DVI to HDMI cables.. maybe bad NVClean driver setup (bad inf) or something.. If only there were some schematics for zbook g6 that would be solved quickly..

Anyone tried using external outputs with rtx 5000 ? Does it work ?

Try to reflash vbios chip using external programmer. And before soldering out flash chip check if it have 1,5v supply on its first or last pin. If no 1,5v then vrm is faulty

I wonder about 1-3 coils, theyre core supply voltage. Rest coils and caps are okay. gpu heatsink cold ?
