How We Test

Hardware and software settings carried over from our initial round-up allow me to compare the performance of every tested X99 motherboard to the most recent products. Charts include the three most closely-sized competitors:

    How about a test of the ASRock EPC612D4I. It has four memory slots.

    Sorry, I don't have any DDR4 SODIMMs yet.

    Is it just me or does the lets compare to other boards bit not contain any other boards to to compare against?

    True. However, that section is pointless as it has no direct rivals - I think they're using a standard template and they had to fill something in there.

    For that socket/platform its almost a complete waste - all those unusable memory channels and pcie lanes that make the 2011 platform high end have been stripped away

    it's really just for people who want more cores. So, feel free to ridicule anyone who tries to pair it with an E5-1620 :p

    Testing this on the stock cooler is useful information, but this mobo will only shine when water cooled. I'd like to see the tests repeated with a closed loop cooler attached. Either the Cooler Master or Corsair H100 (which i've heard will work with that bracket as well). If the point is to pack lots of cores into a small form factor, not overcoming the thermal throttling seems like a weak test.

    While not as good as it's micro atx counterparts (obviously), I am very impressed by this motherboard.

    So if somebody that doesn't need all the PCIE lanes or memory lanes but just the pure power of a hexa/octo core CPU in a small package, then this is the best solution.

    The cooler bracket also seems to fit a Corsair H100i/h80i as seen in Linus's video.

    So other X99 boards get ripped for not being able to do 4-way SLI or 3-way with a PCIe RAID controller but this one gets a pass on those items plus numerous others (lower OC, lack of memory expansion, high price, etc) and receives an award. The board reviews here are just becoming a joke.
