IntelNUC 7 Mainstream Kit (NUC7i3BNH) - Core i3, Tall, Add't Components Needed

I'm very impressed with this nifty little NUC. Just got it today along with 2x8GB of ram for testing. I got the short version that only has room for a NVMe card. Testing DragonFlyBSD on it and everything works, which means that it will also work well with Linux and FreeBSD (though I don't know about video accel in FreeBSD). And Windows too, obviously, but who cares about Windows :-). Here's the official CPU identification:CPU: Intel(R) Core(TM) i5-7260U CPU @ 2.20GHz (2208.06-MHz K8-class CPU)This cpu is a 2-core/4-thread Kabylake 'U' mobile cpu. I verified that it Turbo's to 3.4 GHz on both cores (all four threads), and will stay there when I load them all down. Performance is roughly equivalent to an older Haswell i3-4130 desktop system (which was a 2-core/4-thread @ 3.4 GHz), though of course with NVMe based storage the filesystem is a hundred times more responsive than a hard drive.I tested: network booting with PXE, usb booting (EFI), and NVMe booting (also EFI). The ethernet works (if_em or if_emx in BSD-land probes the Intel I219-V4). The Wifi works (if_iwm and iwm8265fw firmware). USB works. Sound works, X works fine on a 4K screen. I didn't have a usb-c cable to test a second screen (got one, see note at end). AHCI not tested but looks standard so would certainly work too. Primary screen is via HDMI. xrandr output:DP1 connected 3840x2160+0+0 (normal left inverted right x axis y axis) 610mm x 350mm3840x2160 60.00*+ 30.00 25.00 24.00 29.97 23.98I am very impressed with the performance. It has no trouble running X on a 4K display, no trouble running chrome, no trouble running YouTube full-screen on the 4K display. Very responsive to the UI. I couldn't test a 2160P stream due to network bandwidth limitations but 1440P on a 4K screen looks wonderful.Power consumption is equally impressive. Here are the numbers at the plug with a kill-o-watt, and keep in mind this is WITH a NVMe card plugged in and Wifi operational:14W - BIOS11W - During kernel boot10.5W - Idle, VGA console (C1)10.3W - idle, frequency management only (C1)10.0W - idle, C-state management (C7)12.0W - typical downloading over the ethernet10.0W - chrome idle20.0W - chrome loading YouTube page10.0W - chrome idle w/YouTube page loaded13.0W - Video playing, embedded (1/4 screen)15-17W - Video playing, full screen (4K screen, 1080P stream)11.3W - Video paused, full screen13.5W - YouTube music (1/4 screen, very little video action), over Wifi23.2W - YouTube music + 32-process 8KB block size random read test from NVMe storage. All cpus fully loaded. 1.4 GBytes/sec read rate.Temperature tests:48-50C - Typical idle54C - youTube music playing, low load62-70C - fully loaded test (as described above)Note that both cores (all four threads) stay at 3.4 GHz turbo during the fully loaded test. Temperature increased rapidly to 62C, then fan came on (which I can't really hear), and temperature slowly increased after that to 70C and then stabilized there. Frequency remained fully Turbo'd. This fully loaded test is not using the FP unit heavily... its mostly integer, plus whatever chrome is using (probably mostly GPU video accel and not cpu FP). So its not the absolute maximum load I can put on the system, but its already well over what most people would run it at even doing lots of stuff. Unloading the cpu but leaving YouTube up playing music, temperature instantly dropped to 65C and then headed down to 56C from there.I have to say, I am very impressed with this little guy. Being able to get Haswell i3 desktop performance from a few years ago packed into such a small form factor is amazing. I've tested many NUC's and BRIX's (as well as many other systems), and this is really the first NUC/BRIX form factor that I would be happy to use as a workstation. Mind you, I have servers to do major compile jobs on and such... I'm talking mainly for X windows driving two 4K displays with lots of xterms and chrome windows up. Video, music, etc. Not heavy processing.Addendum: I got a USB-C to HDMI cable and after a bit of scraping I got it working. The second display ran at 4K@30hz so now I have a USB-C to DP1.2 cable ordered to see if I can get them both running at 60hz. I'm still going to give the NUC 5 starts, but I will note that the NUC's USB-C port is deeper than spec, so the cable wouldn't plug in solidly or connect at first. After a bit of shaving of the cable housing I was able to push it in deep enough to connect. Insofar as I can tell, this is a problem with the NUC usb-c port being a bit too deep inside the case. I also noticed that the motherboard in the NUC wasn't properly seated, and corrected that, but the usb-c port issue looks unfixable (other than by shaving the housing of the cable I plugged into it).Addendum2: Sound output on the stereo plug has serious hum. Tried everything... grounded speakers, ungrounded speakers, even found a three prong power supply for the NUC. So I gave up on using the stereo output plug. The HDMI sound output works fine, no issues at all, so I used that. Not going to dock Intel a star for messing up the stereo output since an alternative is available.Addendum3: Still can't test with a DP1.2 cable (snafu trying to order it on Amazon, package was returned for reasons unknown), but I have two 4K monitors running at 30Hz no problem (which is fine for a workstation). Have been using this NUC as my X workstation for a while now and it works great. I'll note here that if you are having problems running 4K@60Hz, its probably that your cable isn't rated for it. In BSD/Linux you can just use xrandr to set the vertical refresh to 30hz to work with older cables.I would also like to note very specifically here that I am using a *real* NVMe SSD and not the Intel Optane junk. *NOBODY* should ever buy Intel's Optane junk. It's a rip-off and it makes zero sense to waste the NVMe slot on it. Buy a real NVMe SSD card, like a Samsung 950/951/960 series NVMe card (e.g. like a 250GB+), and install the system directly onto it. Remember that this NUC is bare-bones. So you need to also purchase the ram (DDR4 laptop memory, I recommend 8GBx2) and the SSD (I recommend a Samsung NVMe SSD of some sort). If you need tons and tons of storage, get the taller version of the NUC and install a secondary SATA SSD or HDD drive in addition to the NVMe system drive. I would still recommend a SSD as the secondary SATA drive but with a little work you could probably fit one of those fat 4TB 2.5" Seagate HDDs in the tall NUC (I have the short NUC so I can't test whether a fat 2.5" Seagate would actually fit in the tall NUC form factor).As I said, I am still going to give the NUC 5 stars even with these deficiencies. Buyers are warned :-). Get a USB-C to DP1.2 ('Club' brand adapters are what Intel seems to recommend), have an xacto knife or box cutter handy just in case you have to shave the housing to get it to plug in solidly (remember, you can also shave the NUC case housing instead, if you don't want to shave the cable), and connect your audio through the HDMI port rather than the stereo plug.-Matt

This is my 2nd NUC, the first one I bought over a year ago was the NUC5i7RYH and I set it up for my mother as her main computer and it's still working great for her. She always shows it off to friends that come over, she can't believe how fast it is for the size. Your average budget desktop computer you buy at Costco/Walmart/Best Buy are loaded with crap and don't even have a SSD. If you buy a computer nowadays you need to have a SSD, everything is so much more responsive with one. It's a night and day difference compared to the old hard drives with platters and moving parts. The NUC5i7RYH works great but the fan can be annoying, it will just start blowing full blast out of nowhere and I hate fan noise. My mother doesn't seem to care at all but that was one downside to that model I didn't like.So moving on to this new model, I was going to buy the NUC7I7 model instead of the NUC7I5 but a review of the i7 model on nucblog.net mentioned the fan noise can get up there again so I decided to just go for the i5 model this time. This computer was for my brother, his computer is 9 years old and was on its last legs, he liked my mother's older NUC model a lot so that is why I got him this one. He is a college student and didn't want a laptop at all, he uses a 32" HP OMEN 2560 x 1440 HDMI monitor with this NUC and it works great. He doesn't game at all, just productivity software and internet browsing so this NUC works great for that.Hardware I bought with this NUC:-Samsung 960 EVO Series - 250GB PCIe NVMe - M.2 Internal SSD (MZ-V6E250BW)-Kingston Technology HyperX Impact 16GB RAM DDR4 2133 HX421S13IBK2/16I loaded up this NUC with 16GB of memory and a 250GB Samsung 960 EVO SSD. Installation is always extremely easy, the user guide just has pictures with not a lot of detailed explanations so if you need a better guide, just search on YouTube for NUC install videos and you will find plenty. I’d follow these steps below to make sure you have the best experience with this computer.1. Install SSD and memory into NUC.2. Turn on the NUC and before you install any OS, update the BIOS to the latest version. Mine was one version behind so I went onto the Intel website and downloaded the latest BIOS file and flashed it. After you flash to the latest BIOS I’d go exploring in the BIOS settings to make sure it’s detecting your memory and SSD.3. Once your BIOS is on the latest version then install the OS. I installed a copy of Windows 10 Pro 64 bit. I have an .iso image file of Windows 10 so I just used RUFUS (rufus.com) to copy it onto a USB 3.0 stick to make it bootable.4. Insert your USB stick into a port on the NUC and turn on or restart the NUC. It should boot from it so you can install Windows 10.5. After Windows 10 is installed, go to the Intel website for this NUC so you can download and install all the drivers for it. I usually start by installing the most important drivers first like chipset driver/video card driver/wireless card driver and so on. After you install a driver, I always restart the computer even if it doesn’t tell me to, better to be safe than sorry.6. After all the drivers are installed, hit up Windows Update to see what it wants. Once Windows is fully updated and all the drivers are installed then I would start installing software like MS office and whatever else you need.7. Once everything is configured and setup the exact way you want it, an extra step you might want to do is to create a system image of everything. Windows 10 has a built in tool that will let you do this but I'd avoid it. If you perform a Google search for “Macrium Reflect” you’ll see a free version of the software on their website. This software will create a system image which is a copy of everything so if Windows 10 crashes or has some other strange unrecoverable issue you’ll at least be able to reflash the image and not have to worry about installing all the drivers and programs again.So far this computer has been what I expected from it, fast and pretty quiet. The fan inside this NUC doesn’t get loud at all, nowhere near as loud as the old NUC model I mentioned. As long as you follow most of the steps above that I mentioned, you should NOT run into many issues. My brother has only been using the computer for a few days now and so far so good!**Edit on April 6th 2018, this computer is still running smoothly. Not a single issue and it's used every day. You can't beat a NUC for a general usage computer if you want a desktop computer and don't game.

Unbelievable performance from a "desktop" computer I can hold in my hand! As fast as any desktop computer and with newest Intel video chip (650), this little wonder will handle almost any game. Actually, will handle any game, but the more resource demanding games will have to be run at lower resolution. Even more amazing is how easy it is to assemble (less than an hour) and to load Windows 10 (about 20 minutes or less). It is an amazingly fast computer which takes up practically no footprint. In addition, I am using this computer to run on a 55-inch high-resolution TV and this little wonder will run at the TV's full resolution with no problem. Amazing! I come from the era when computers ran DOS (and barely at that) and desktops were really "floor computers" as they were so heavy and large. This Intel computer is so fast and has so much storage space (512 GB SSD AND a 2 TB hard drive) with so much RAM (32 GB), it is unbelievable to an "old school" computer person such as me. This model is pre-Optane, so I can only imagine what the Optane powered computers must be capable of for computing needs!
