    I'm too lazy to re-read the discussion in the E7450 thread but recall that no one had persuaded an SSD to work in the WWAN slot although Dell had marked that slot as WWAN / SSD in early documentation.

    There's also some interesting discussion here about the main M.2 slot in the E5470 and the need to turn off the SATA in the BIOS in order to get the PCIe to work. Something else which might be of interest to the E5470 owners is that the Dell 5570e WWAN card works fine in my E7450, so the same might apply to the new notebooks. The 5570e is only 3G, not 4G, but is a lot less expensive.

    Hi folks.

    Lots of interesting information on this thread. The E5470 looks like a decent machine on paper, but it's elusive out in the wild. I'd like to have a play on one before I buy ... but that doesn't seem to be possible.

    There is a discussion on another thread comparing the relative merits of the E7450 & E5470, but I thought I'd post here in the hope of hearing some first hand experiences.

    http://forum.notebookreview.com/threads/help-me-decide-e5470-or-e7450.789258/

    For starters, when it's under load for a couple of minutes (for example, performing a build of a C++ project) does it get really hot? What's the fan noise like?


    Thanks,
    Aaron

    Yes it gets heated up on the right palm rest under load, not that its unbearable though. No fan noise.

    A bit of heat, but not too bad - I can deal with that.

    Good to hear the fans stay quet.

    Thanks for the info,
    Aaron

    My E5470 (i7 6820-HQ IGP arrived)

    As expected, 32GB works.
    able to install 2x16GB DDR4 SODIMM 2133(PC4 17000) CAS 15(15-15-15-36)
    G.SKILL F4-2133C15D-32GRS

    EDIT: same throttling behavior as the T460p series.... sigh...
    a little pointless to get the highest-end 6820HQ when it throttles to 2.5ghz (below spec's 2.7ghz)

    CPU-Z
    It does hit 43W in the beginning, then throttles to 35W... goes under 2500mhz... sigh

    Did a clean Windows 10 install

    Clean ISO didn't have drivers for Ethernet/Dell wifi card
    Install ethernet drivers manually, did WIndows update
    Then installed the following drivers manually. No missing drivers after that
    • Intel RST F6 driver (probably optional)
    • Intel RST Driver+Management Console (Probably optional)
    • Dell ControlVault2 Driver & Firmware (for fingerprint/nfc/smartcard)
    • ?BIOS?WWAN drivers?
    surprised that Dell defaulted to legacy boot mode, not UEFI... now, I have to reinstall... sigh

    EDIT:

    installed ubuntu 15.10 (kernel 4.2) (windows 10+ubuntu coexist via dual boot)
    Missing wifi drivers (Dell 1820A) and Intel 530HD IGP support. Kernel 4.4 has suport for both

    Ubuntu 16.04 LTS will come with kernel 4.4 LTS... will wait for 16.04 instead of trying to patch the kernel myself

    EDIT2:
    Ubuntu 16.04 LTS daily ISO works (wifi drivers + Intel 530HD skylake IGP support)

    Bummer about the throttling. In Windows, does switching to the "High Performance" power plan make any difference? Did Windows pull down any DPTF drivers automatically, and if so, what version?

    I haven't seen CPU temperatures in the 90's since I had my T420s (which would get to 95C and start to throttle). I wonder if the throttling is imposed because of the temperature (in which case a better thermal paste might recover some CPU speed) if there is a simple built-in rule based on CPU speed or power drain. It's probably the latter: Intel's CPU specs say 45W / 35W with this description of "Configurable TDP-down".

    Configurable TDP-down is a processor operating mode where the processor behavior and performance is modified by lowering TDP and the processor frequency to fixed points. The use of Configurable TDP-down is typically executed by the system manufacturer to optimize power and performance. Configurable TDP-down is the average power, in watts, that the processor dissipates when operating at the Configurable TDP-down frequency under an Intel-defined, high-complexity workload.

    The tests were run on Windows 7( OS installed directly by Dell). I assume all necessary drivers were installed, can't tell because I wiped it and put a clean ISO windows 10

    Can redo the test in Windows 10 later , dptf drivers were pulled in via Windows update

    Yeah, I'm tempted to redo the thermal paste. Heard bad things about Dell(bad/overapply of paste in factory). Seems like CPU is idling around 50C, which is abnormally high (ambient is about 23C)

    Internally, looks like single pipe heatsink. Will post pics later

    Windows 10 Pro

    DPTF 8.1.10605.221 (10/23/2015). Pulled in from microsoft update. Dell website has same driver for E5470

    High performance

    same throttling behavior




    EDIT: I ordered a 32GB m.2 2242 SSD to test WWAN slot
