    Can't comment on noise yet. We have some big fans and dehumidifiers running in the office because of a water incident on Monday which drown out any noise that could be coming from this system.

    Right. Totally agree with you. The noise from the laptop even in idle mode above the noise level of a standard laptop by 6 dB. When working under load, the noise is simply wild. As a specialist from the Dell department said, the noise level is 58 dB at maximum load. During long-term work under load, the processor falls into throttling. Therefore, maximum performance is available only for a few seconds. It was a disappointment.

    What extra HDD options does the Zbook have?

    Going by the customisation options, you have 3 M.2 slots, one SATA slot and another SATA slot where the optical drive plugs into.

    It gets really expensive, though. Easily twice as much as the Precision. If anyone is getting these machines for personal use, and isn't having a company pay for them, I'd strongly suggest they upgrade only the CPU, GPU and other non-replaceable components, and self-source RAM and storage.

    $600 for 32 GB DDR4 (that is neither overclocked nor ECC, but bog-standard 2666 MHz JEDEC), even at the height of the DDR4 shortage in late 2017 and early 2018, would be outrageous.

    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.
