    Only true for WWAN starting with Skylake (and at least some Broadwell) models; no more WLAN whitelists.

    oh man, I ordered mine 3 weeks ago, was supposed to be shipped on August 1, not it got postponed to August 10. Hopefully, they won't change this again.

    However, after reading about your issues, I wonder if I shall cancel the order or not. Currently, I use a 2015 15" MacBook Pro with Bootcamp (.NET developer), is all good, except 16Gb sometimes is not enough when using a couple of VMWares.
    Really, scratching my head now what to do, is it worth the wait or not :(

    How is the noise level under normal load?

    I'm looking for portable/ultra portable that can take 32GB RAM and\or 4K display. I love my surface pro 4, but it's just 16gb ram which is not enough for me.

    Is anything out there similar to my requirement?

    I suggested those because that user was considering an alienware 17 r4 (4.42 kgs).
    I think your needs are really different. If you are seraching an i7-7700hq, you could consider a dell xps 9560 or a dell precision m5520

    I'm in the same boat as the OP. I have access to 2 work provided P71 machines. One has the Xeon 1505M and the other a 7820HQ. Both with P4000m GPUs. The CPU cooling is grossly inadequate, even for the 7820HQ. Both processors score within a point of my XPS 15 9560 (7700HQ) on Cinebench R15.

    What's the point of spending up to +$700 on a processor upgrade if every processor will ultimately throttle down to the speed of an 7700hq? I guess if you only have single core requirements or need ECC?

    I have not torn this model down yet, but if Lenovo is using a similar heatpipe design as the P70, there is no way a single heat pipe (shared with the GPU mind you) can keep up with a sustained 45w load. I haven't had a chance to test the P4000m yet, but I suspect it will also be thermally limited at its limits. There is no way a $4,000 machine with P5000m and 1535m v6 will perform anywhere near its potential.

    Such a bummer.

    Just received my p71, with 64Gb RAM, Xeon 1505 and I got quite disappointed, the CPU scores about the same 597cb as my 4 years old MacBook pro in Windows BootCamp mode (i7 4870HQ), like WTF.
    Man, only if MacBook would support 64Gb, or at least 32Gb, would never buy anything else :(

    Now, got a dilemma, on what to do with this P71, yes I like that it has 17" HDPI screen, 3 SSD and 64Gb, but CPU, why throttle it? :(

    The issue I see here is the undersized heatsink paired with a Xeon/faster i7, you would need more than a repaste to fix it. Even with liquid metal, I don't think it would help much since it doesn't magically allow an undersized heasink to perform properly.


    I would also be careful of running the CPUs at full turbo due to the CPU VRM not having any heatsink (look at the top).


    But hey, at least the mounting system has 4 screws.
