    Thanks, but that wasn't exactly my view. 🙂 It seems you've misunderstood the idea. She was to use only a modified cable between the motherboard and display, without a converter board at all. Re-read the latest replies from DevilAnGeL, the author of the "Ultimate 8770W yet?" thread. You even wrote there earlier. I've read that DELL workstations also use a similar converter board (with a newer microprocessor). I can't say how compatible it is with HP.

    I think so. But in your case, I would start by examining the characteristics of your current screen. AIDA64, then panelook.com 😉

    Yes, I've read that before. Overall, it's encouraging. But there are a lot of things I'm not happy with: - I think installing 4K monitors with high refresh rates on a less modern graphics card is too much. It's trendy, I agree, but it significantly increases the graphics card's workload in 3D, which will lead to frame rate drops and stuttering in games. I'd stick with Full HD and 60Hz — that's the bare minimum; - I have no idea how to buy on TAOBAO; - I'd prefer to make my own cable. 🙂 Sounds like a good idea, I agree. I would also buy a screen from the same laptop model as the graphics card was intended for, because of... your least favorite word. 😀 Although, also need to pay attention to the screen hinges. While browsing our marketplace OLX, I discovered that HP ZBook 17 g5 uses LP173WF4-SPF7 (LG Displays, IPS, 60 Hz, eDP, 30 pins — everything I need to be happy 🥰) as its native screen. The seller claims that it is compatible with g3 — g6. Please treat your hands. Good luck.

    This sounds quite logical and correct! 👍 The answer can probably only be given in practice... How difficult is it to find them for sale? Was there any information on how successful it was?

    🤩 This is simply great! It seems that it is better to buy M6700 with LVDS cable and display? Have you ever upgraded our EliteBooks (8560-8570-8760-8770)? 😉
  7. Vladka76
    I guess that the DELL M6700 (with eDP), but not M6800 - is the best one for upgrading video cards? Yes, I've heard that a discrete graphics card without an iGPU (without Optimus) is 15-20% faster. That's comforting — and it motivates to figure out how to help EliteBooks...

    I'm afraid just one cable won't be enough. You're right, a complete DC kit consists of a color depth converter board and two cables: an outgoing eDP cable from the mobo to the converter and a LVDS cable from the converter to the display. I tried searching for the complete kit but couldn't find anything. There are a lot of DC cables, by the way - will be no bidding war here. 😀 I also thought about buying such a cable to start creating my own experimental EDP cable.
  9. Vladka76
    Yes, all DELL's similar workstations have iGPU enabled and working - so they can work with newer cards even via LVDS interface (I've read about it, this was not my own experience; I've even heard that MXM 3060 (Ampere!) worked well with LVDS display). But our beloved HP EliteBook's don't have iGPU at all (newer ZBook's already have it)... Yes, I've heard that in DELL's Pascal cards works only with Engineering (early) vBIOS, but Turing cards all works well. Now I can only dream about RTX 3000 (standard MXM 3.0b) working in my 8770w... 😕

    I recently found something: https://www.ebay.com/itm/145765636591 This cable theoretically (as it seems to me, may be wrong) connects the motherboard and the original display for the DreamColor on 8760w, 8770w - LP173WF3-SLBx ("x" may be 4, 3 or 2). All is perfect (S-IPS, matte, exotic 10-bit color depth), but connection type of this display is 50-pin LVDS. 😀 Moreover, he is relatively old and difficult to find in new condition. The main disadvantage of this option is that installing this display and cable does not improve the laptop's compatibility with fundamentally newer video cards. A much more promising option would be an eDP 30-pin cable (for FHD displays), which respected @GuitarG is working on...

    Interesting. The FBGA code "D9RVX" on your chips means the model name MT41K512M8RG-107:N, officially also 1866 (from the datasheet: the "-107" marking = option "1.07ns@CL=13 (DDR3-1866)"). This chip's frequency is the same as one I've encountered, but the FBGA code on those I've seen was slightly different from this one. What's preventing good memory chips from running at full speed? Perhaps poor-quality resistor arrays on the data buses (all my original modules have ceramic, white resistor arrays)? Or the firmware on the SPD flash IC? It's sad. This is often the case with the Chinese – they copy almost everything well, but somewhere there's always a flaw that ruins everything... Another my photo. 🙂 Compare the quality of the sticker on the other side of the two modules (original on top, counterfeit on the bottom). The original has an aluminum base and a black ink printing, while the counterfeit has a paper base and white ink with a low-resolution print. And a resistor arrays are different in color and material...

    Here's a photo of Samsung chips and a screenshot of their datasheet. Beware of such memory!
  13. Vladka76
    I'm very sorry, but what frequency memory modules do you have installed? 1600 MHz or 1866 MHz? Model name HX316... or HX318...? Those symbols are hard to read. Unfortunately, in any case, these are new, but counterfeit chinese modules, unlikely to be made by Kingston (the OCR incorrectly recognized, meaningless word "DIMSION" is clearly visible). I recently encountered two such modules, supposedly running at 1866 MHz: one with Samsung chips, the other with Micron chips, as in your case. Both worked fine, but... at 1600 MHz. 🙂 I tested them on two laptops with i7 CPUs (hp 8770w and Dell E6540). Moreover, the markings on the Samsung chips indicated that they were officially 1600 MHz (but the Micron chips were officially 1866 MHz). Check the actual memory frequency on the BIOS startup screen or using CPU-Z (see the "Memory" and "SPD" tabs). If there you'll see 1600 MHz (or near 800 MHz real frequency value), but you bought 1866 MHz, return those modules and look for genuine Kingston modules with Kingston chips, manufactured between 2017 and 2021. I was lucky enough to find three of these, and they work perfectly at 1866 MHz. Below is a my own photo of two modules (the original on top, the counterfeit on the bottom). Find 4-5 differences. 🙂

    The plan is good, thank you! 🤩 I believe that, using its data, anyone (familiar with a soldering iron) can create their own cable-mod. I don't have a test 8570/8770 or a test e-DP 30-pin screen, so I don't want to risk it without your help. Please, improve your health first, and then you can work on it. I'll wait; it's not urgent.
  15. Vladka76
    ??? But those are just rough notes, so it's hard to figure out which pin on one connector should be connected to which pin on another. I could just try to guess, but doing that on a new eDP screen and my only working laptop is scary. I'd be very grateful for a complete pinout diagram when you get better. I'm probably not the only one.
  16. Vladka76
    Why? There's always a way to check this: desoldering the ROM chip, downloading its contents using a programmer, and examining the resulting dump. The firmware's internal version number can be used to determine which OEM manufacturer it was developed for. Generally, you can do a lot with a soldering iron. 😉 Moreover, attempting such an upgrade without proper soldering skills and a programmer is risky. I've seen MXM videocard's sellers offer the option to flash the card with the buyer's vBIOS for free upon purchase. Or they might flash the version that, based on their experience, is most compatible with the buyer's workstation. I would definitely take advantage of this opportunity when purchasing. 😉 You can also start by looking for a Quadro M2200, as long as the seller agrees to flash it with Dell's vBIOS before purchasing and gives you some time to test it. 🙂 Theoretically - yes, BUT - for such a hot and big card as 980m, you need to mod 8570w, as the author of the topic did. Re-read first pages of this topic. 🙂 I would start with the Dell vBIOS. It's better to search on the right by the name of your GPU and then select vBIOS from Dell: https://www.techpowerup.com/vgabios/ The thread's author would have been better off answering this question. I haven't used Clevo. I think they're less compatible than Dell.
