Sweet, thanks for the info. I think I could stack kapton tape on the blank side of the male end of the adapter for a more snug fit as well..

It seems they make boards that act like couplers for eDP cables, and a cable with two male eDP connectors, being 40 pin .4mm pitch to 40 pin .5mm pitch.. it’ll be a bit pricey, but I think I can cobble together a solution if it turns out the lack of the retaining clip is the issue with these cheap adapters.

Recently ordered a dell precision 7740, to replace my m6800. It has a nice cpu, the 9980HK, but no gpu, and otherwise low specs outside of the big battery.. as such, I’m looking into upgrades. Currently looking at getting a gpu, along with all the needed cables, required new heatsink, and installing a better display. I have a panel I got ridiculously cheap a bit ago, from a guy selling the display assembly from an x17 r2, since the magnesium back panel was cracked. It’s the right size, eDP, 360hz, but it appears its .4mm pin pitch. From a bit of hunting around, it seems the precision 7740’s UHD 4 lane panels are .5 mm pin pitch. Model number on it is B173HAN05.2. (As a side note, I do know the UHD cable only works with the infrared webcam, and I’m fine with just wrapping the lead in kapton tape and having no webcam.) On this forum I’ve seen people use adapters for a discrepancy like this, with some mixed success, with TheQuentincc’s success using one on a 7550, and a fried lcd power line on page 8 of the owner’s thread of the 7#40 series of precisions. All of this, has lead me to wonder, what’s the deal with these exactly? Should I watch out for bad adapters, keep an eye on the pinouts being the same, take extreme care with my install, or just not even bother? From the looks of it, the flex pcb ones don’t have a locking clip which seems like an important part of this..

From the looks of it, these boards have 3 VRMs but spots for six.. referencing a boardview of the LVDS version of the mobo, the spots are in pairs of two, so two next to each other will feed into the same coil and cap because of how the board is wired, so it does seem possible to solder in more VRM's if your oc is pushing the stock ones real close to what they're rated for, but I'd check the pinouts of those pads manually before soldering

Someone was able to upgrade to the RTX 3000 before Not sure where to get these RTX gpus outside of ebay, maybe a recycler? These were in some models of HP Zbooks IIRC. 17 G6 was the last with the mxm slot IIRC Edit: Forgot to mention that there are some smaller companies that make these gpus, an ADLINK RTX 3000 was shown in this thread a bit up, as an example

Well, secure vault is working now. ended up replacing that ribbon with one from a parts laptop and now everythings (mostly) fine, just that theres no input being registered from the reader, so ill just buy one to put in. Thanks for pointing me away from the board. Got to reading over some schematics i found before checking my email

That nets me the installshield exe which gives the same error, but i was able to get the msi by running the exe from the command line with the /x flag, and copying it from temp before selecting anything, but it looks like it has to be launched by the initial install shield exe, as it errors out saying that the wizard was interrupted. Was also able to find the drivers in the temp folder too, it seems it has an issue running the installer rather than extracting for some reason. Running the controlvault fw upgrade util after copying drivers it was complaining about gives an error of not being able to detect controlvault, and now i remember seeing sharpie on the board when swapping the cpu yesterday. I'm guessing the board was swapped with one that didn't have the chip (if it works that way, I'm not familiar with these high end dells) and they left the old palm rest with the two readers in place, seems I'm out of luck unless I can track down a board with it, or find the ic and solder it on myself

Does anyone know how to get the fingerprint/rfid readers working in windows 10/11? They both show up as unknown devices in device manager, and when i try to run the dell control vault driver installer, it cannot extract an msi file to get on with the install, with the controlvault firmware updater not being able to proceed either, since it can't find dlls related to the two devices installed. I might just try installing everything on windows 7, then updating from there.
