    Even on high end there are no proper heatsinks for vrms its that silly solid chunks of aluminium with minimal fin stack that dominates. It was refreshing to see Gigabyte go back to old school finned heatsinks for their X470 board.

    Flash over substance. It's a pitiful way to make a product.

    Not to mention it looks worse than aluminum or copper fins.

    ASUS and Gigabyte released VRM coolers back in 2013 that would be used with water systems as well as air (hybrids). This was for quad core non-prosumer CPUs, too. But, we have certainly progressed as an industry. Now, we can have really cool paint and LEDs instead of efficient VRM cooling.

    Hopefully Buildzoid will get a hold of this model motherboard and verify it is what MSI says it is. I'm so tired of marketing lying about computer components, I don't believe much of what I read from the makers. Thus I am in "prove it" mode. Unfortunately, most reviewers either don't look or don't know what they see if they do.

    This is one of the reasons we have our power delivery component table in our reviews now. Gavin knows what he's talking about - he did a good deconstruction of the B450 boards that exhibit the behaviour you are describing.

    it´s an 8 phase. as 2 "phases" are always in phase and therfore can not count as two seperate phases.

    one is marekting the other is reality.

    mmm no this looks like an actual 16 phase, just a "dumb" 16 phase because of the doublers.

    the cooling looks pretty crappy though.

    i looked up the datasheet for the doublers mentioned and it describes them as outputting 2 PWM signals 180* apart so functionally its rectifying 16 phases, but the regulator sees 8.

    the datasheet if anyone is interested:

    neat trick, and according to the sheet the doublers can also function as quadruplers so if one wanted 32 phases for some insane reason they could do that with the 8-channel controllers

    Been really disappointed with their last gen X399 mobo from MSI. Lots of issues for months. Not many BIOS updates either. Pretty much felt like abandon ware after only a few months. Hell not even the mobo debug LED is working properly. It never has, and that speaks volumes. Spend your money wisely guys!

    Nice review, thank you!
    Does HPET was enabled?
    HPET enabled gives bad DPC Latency results.

    reasonable 500 bucks with m.2 card (about $ 90 to 100 from asrock or highpoint m.2 AIC), so this is a $400 good option for those who want massive m.2 drives capable mobo

    Ok, this is considered a high end desktop setup, usually for workstation type duties.

    Can we please get some motherboard reviews with what motherboards do?
    For instance, can you please test the M.2 slots, USB, LAN, wireless if it has it, multi threaded or multi core capable work load?

    You have all these features of a motherboard and what we get is some game benchmarks?

    very nice information you share with us. thanks for this.

    Would it be better to buy 4x16gb dimms for x399 or 8x8gb dimms? Would it make a difference for performance for 1950x / 2950x cpus?

    > Xpander-Aero four-way M.2 PCIe expansion card

    Any plans to test this card with 4 x NVMe SSDs?
    Also, on similar motherboards, there is a BIOS/UEFI option
    to "bifurcate" x16 slot logic e.g. ASRock uses the
    nomenclature "x4x4x4x4" and ASUS uses the
    nomanclature "4x4".
