lasted one night 4/1/2018 6:45:54 PM

Pros: -looks good
-easy to install and update
-quick response from their support on a holiday Sunday

Cons: -didn't last long
-error codes not in manual, when I searched for mine (4F) I found out that code was 'reserved' - not a lot of help there
-didn't recognize M.2

Overall Review: Bought this a while back and just used it yesterday. Everything went well at first, I was able to update the bios, install Windows, update drivers ok. Left it running over night - no issues. the next day while I was using the PC it turned itself off and the power button started blinking. I was not able to get it to boot up again. Clearing BIOS, adding devices one at a time - nothing.

I opened a ticket with MSI support, and they replied pretty quickly considering it was Easter Sunday. I did what they suggested and got an RMA number. once I get it back I plan on updating this review appropriately.

Something wrong with this motherboard. 9/9/2017 3:15:25 PM

Pros: I bought this model for the features and appearance. I was waiting for HEDT to support m.2x4 and this generation of mobo/processor does it. The motherboard is constructed well with no visible flaws, the connectors appear to have been manufactured to be reasonably strong; the capacitors, chips, buttons, heatsinks and mostly everything seems to be of superior quality.

Cons: I have to update my review. Where did the update to my review go?

I [enabled] the turbo setting on the bios and it has no effect. When I start the PC the and check the performance turbo boost doesn't work- I restart the computer and bios fails. I enter setup and exit then run the PC, then the turbo mode works; why doesn't it work on initial boot up? The processor is designed for turbo mode- not outrageous overclocking. I have push/pull setup on a 240mm liquid cooler- even at full turbo the processor barely touches 50° C. I'm not trying to burn up equipment, just use it like its intended to be used.

I don't know what the hassle with the memory is. The memory clock of the processor is 2666MHz. Is the technology junk? I had a Sandy Bridge i7 running DDR3 at 2666MHz and no problems with the system needing to reset.

I want it work as advertised. How could I build a PC and sell it to someone? Wouldn't someone complain that their new rig is a piece of junk? A motherboard advertised to overclock only running at stock speed and with DDR4 3200MHz that only will clock at 2133MHz. I think I'd have serious problems selling these PC's to anyone.

GUI BIOS is irratiting. I don't need stupid little pictures and a complicated interface. I'd much prefer simple lines of information and basic controls; that's just me- I'm sure everyone else enjoys irratiting garbage.

Overall Review: I would recommend this motherboard- MSI builds quality products. I was going to buy the other MSI motherboard that cost alittle more but this model had all the features I was looking for; plus it's white, I've never had a white motherboard. xD

64GB 4x16GB G.Skill Trident 3200Mhz junk DDR4
Samsung 960 Pro m.2x4 512GB
Corsair Crystal 570X Case
Corsair H105 240mm Liquid CPU Cooler

I migrated EVGA 980Ti FTW, EVGA 1000W Modular Power Supply, 2 hard drives and 1 Samsung SSD from my old PC.

I wanted an updated processor and enough RAM to run Adobe and Maxon applications- there is no stress with 16 threads of processing power. I have a lot less lag in C4D compared to the 4 core/8 thread i7 I was using. The processor is more power than a video game requires although I'd recommend getting an i9 processor over the i7 due to the difference in PCI-e bus lanes. For rendering with Maxon if that is what you are going to be doing because Maxon has the ability to split renders between 2 graphics cards. 2 x GTX 1080Ti graphics cards is allot of bang for the buck but only support 8bit color channels whereas NVIDIA Quadro P6000 supports 10bit color channel but costs $5,600 so the cost of 2 of those in SLI would definitely warrant spending a little extra on a processor to build a dream machine. Suffice to say a gaming setup in 4K with a single monitor would do just fine with one 1080Ti. The 980Ti I'm using gives me better than console quality- its actually very impressive in comparison. With the faster memory and extra cores I can see a difference- the processor isn't maxed out. The turbo settings produce better results compared to forcing an overclock. I would say that is the major difference between the previous generations of processors; there's enough headroom in the processor that it doesn't need to be pushed to the limit. With quad channel memory there's plenty of i/o that information doesn't get bottle necked. What I'm disappointed in is the quality of memory on the market and the cost for a substandard product. Really DDR3 was better than DDR4. Reducing the memory voltage on desktop PCs was a stupid idea. Mobile devices and laptops sure, those reductions in energy use are beneficial but something that is designed to plug into the wall come on, no one spending thousands of dollars on a PC is going to care if they save a few dollars on electricity. HEDT buyers would gladly fit DDR4 with liquid coolers if they could get faster clock speeds. I'm sure if the processor was built to handle higher voltage no one would care, I'd gladly pump DDR3 level voltage through DDR4 if the processor could handle it. What I don't want to do is throw the new system in the garbage burning up components because it doesn't live up to what it was advertised to do.
