    At this point I consider the noise level from my system to be acceptable. You must make sure that "PCI express link state power management" is set to "maximum power savings" in Windows advanced power options in order to keep it from revving up all of the time, though. The system is hard to hear when it is idle and I wouldn't consider the noise under load to be unreasonable. Also, if you've tried the Dell Power Management app make sure that you have the thermal mode set to standard/default, for some reason the "quiet" setting is actually louder...

    Regarding throttling, that has been discsused a lot in this thread. You can reduce the throttling by undervolting the system if it matters a lot to you, some users have reported being able to run it at max turbo for extended periods of time with this. Personally, in this day and age I expect CPUs to throttle down from max turbo, it's not necessarily a negative; it just means that Intel has set the maximum clock speed high enough to absolutely push your system's thermals to the limit, making sure that you're getting the best performance that the system has to offer without having to resort to overclocking.

    Darn, now I'm regretting not getting the Zbook - I had the option for getting it for only 30% more than the precision

    Can you describe how I can increase performance by change thermal compound to custom, very expansive but extremely cool?
    Which thermal compound is better?
    Can I install more faster DDR4 memory because 2666 MHz is very slow? Which memory has been tested on this laptop?

    I use Arctic MX-4 in my M6700 and it seems fine to me. I understand that Thermal Grizzly Kryonaut is also good. I'm sure you can find articles online comparing the different choices. I haven't replaced the thermal compound in the 7530, though. I believe that it will give you a slight temperature drop, but you'll get more of an improvement by undervolting. (You can always do both.)

    Dell has the manual posted online which describes how to dissassemble and reassemble the system. You would have to remove the heatsink assembly, use isopropyl alcohol to remove the existing thermal paste from the heatsink, CPU, and GPU, and then apply the new paste.

    You'll have to search the thread about memory support. Some people have tried faster than 2666 and had issues. Keep in mind that the CL increases as the speed increases. The CL is basically the number of clock cycles that it takes for the memory to return a value after it is requested. If you get higher speed memory but it also has a proportionally higher CL, if you do the math you may find that it is not actually faster at all. I recommend sticking with 2666 and getting the lowest CL that you can find. The modules provided by Dell have CL 19, but you can easily find modules with CL 15 (over 20% faster). I saw these modules with CL 11, I am not sure if that could be right? Anyway, no matter what you do, I doubt that it will make a noticeable difference in day-to-day use.

    After a number of weeks of use, I am content with my Precision 7730 - 4 x NVME is quite nice, and it fits into my backpack with ease - whereas other 17" notebooks would hardly fit, this almost feels more like a 15" notebook. I think we all have to be careful about the new updates Dell pushes out because their track record is one reason why this forum is so well populated. As long as your hardware is OK - and Dell Tech Support is usually very able to assist you and help you get what you paid for - HP 17 G5 and Precision 7730 will not likely be very different functionally.

    I can now answer my own question. I am using the U4919DW for one week now. It is connected by DP and USB with the TB18. Video signal can be generated by the Intel UHD 630. The Quadro can stay idle. This was not obvious for me because according the docks documentation the Intel card can not generate such a high resolution. Nice addition:
    You can directly connect mouse and keyboard to the monitor and the monitor acts as a KVM switch for a second device. The funny thing, the monitor has also an USB-C input. So you can connect a second device (in my case an XPS13) with one cable. With this one cable you have the video, usb (keyboard, mouse) and power connection which can make the TB18 obsolete.

    Not quite. The U4919 only delivers up to 90W of power. That's fine for an XPS13, but any 7000-series Precision would throttle badly. The higher power requirement is the entire reason for the dual USB-C on the TB18.

    Yes you are right. For 7k series you have to plug in the power supply too.

    When poking around the options for the new Precision 3540, I noticed that Dell is launching a new dock, the WD19DC, which appears to have a dual-Thunderbolt connector like the TB18DC. Aside from an option in the 3540 configuration page (with no picture), pricing it at $330, the only thing that I could find was this Chinese accessory page which has a few pictures.

    (Clearly plugged into a Precision 7X30, unless the 7X40 looks the same and is not far off)
    I like that it has two smaller cables bundled rather than one huge/fat cable, should make it easier to manage.

    [​IMG]

    Two regular-sized DisplayPort outputs on the back plus HDMI. VGA is gone. It looks like the USB-C port on the back can be used for display output as well. Otherwise the port selection seems to be about the same, one fewer USB port on the back it looks like, and the dock itself is a good deal smaller.
    [Edit] Actually there doesn't appear to be an actual Thunderbolt port here, so no connecting an external Thunderbolt device? Now wondering if this is really a Thunderbolt dock or if it is just using USB-C. Might make sense since it does not have "TB" in the name. Honestly, a USB-C dock would probably be less of a headache. I never had any trouble with the WD15 like I have had with the TB16 and TB18DC. And, as long as it uses both USB-C ports for data and not just for power, it should still be able to drive two external 4K displays.

    There are two other docks that are new, the WD19 (USB-C/90W) and the WD19TB (Thunderbolt/130W).

    [Edit 2]
    Translated the page, it is USB-C and not Thunderbolt after all, and it appears that it can drive one 5K / two 4K / four 1080p displays. (Still would be nice to know if we are talking about 60 Hz in all cases.) Apparently it has a "magnetic suction" USB-C cable as well...

    @Aaron44126, great find. I might get this dock; opens up a couple more USBs and all. And speak of the devil; BIOS version 1.8.2 is out now, with support for the 'WD19':

    EDIT
    There appear to be no other changes in the BIOS from 1.8.1 to 1.8.2:
