Is the m.2 drive supported as a boot drive on this motherboard?

Yes, just keep in mind to keep the driver up to date before doing any major Win10 upgrades. MS has had issues a few times with not checking that first.

would this board work with a Ryzen 7 2700 8 core?

FYI 1700= 1st Gen 2700= 2nd Gen 3700= 3rd gen according to the specs it supports 1st and 2nd gen cpus

Do I need to remove the included wireless card to use a M.2 PCI-e SSD?

No. The M.2 slot for the SSD is on the rear of the board and the slot for the wireless card is on the front at the I/O board.

any issues with the m.2 drive getting hot and losing performance with zero air flow as its behind the motherboard?

Sorry I don't use the slot but I do want to make sure you are aware that if you use this slot, it is only compatible with Nvme m2 (not msata) and will reduce the pcie slot you are using for your graphics card to 8x, instead of 16x. Just FYI.

How is the wifi connection on this board? Is is stable? Is it better than a pcie wifi card? Thanks.

The wifi works good, have not had any connection problems. As far as better that would depend on how you define better, as far as stability the on board it as good as any pcie card, speed wise the on board is a dual band setup. There are faster pcie wifi adapters that you can get but if you really need more bandwidth should be using a wired connection anyway.

Hi All, i saw my CPU Temps were going as high as 85C while ideal conditions, and after some time, nothing showed up on the screen. When i opened the computer i saw the cooler was very loose. On checking around i saw the cooler bracket was broken on one end. Can someone how to get this fixed. Should i get a new one from MSI?

I would do the basic things, Make sure you are still within the warranty, if so contact MSI and see what they are willing to do for you. You could also see if someone you know has the bracket for a Ryzen motherboard that they do not need anymore. You could dive into water cooling (pun intended) with a Simple AIO fairly cheap. installing a Water cooling solution would require all the brackets to be removed. Beyond that, I do not have any other Ideas.

Will this work with the 2200G or 2400G processors without Bios update?

Based on my experience it works with Ryzen 5 2400G without a bios update. However I recommend a bios update (which can be performed with 2400G installed) due to better ram compatibility. I had issues in games before the bios update but not anymore. A bios update on this motherboard is very easy and is performed with a usb flash-disk.

Will a Cooler Master Hyper 212 RGB Black Edition CPU Air Cooler, 4 Direct Contact Heatpipes, 120mm RGB Fan fit on this board? Going to install into NZXT H210i case.

Hello. I am not sure if it will clear the cover for the IO ports at the back or the memory slots in front. I have used a dozen of these motherboards in recent builds but have either used stock cooling or AIO water cooling for the CPU's. I will say this board is very fast and has everything you would expect in terms of features found in higher end full sized motherboards so if you can use something else to cool the CPU or switch to water cooling you would be Ok. Hope this helps.

Is this board compatible at all with DDR4 3600 kits? Specifically the tridentZ 3600 kits.

Yes it should be, If using a Ryzen 3000 Series CPU, There are a few DDR4 3600 kits listed on the QVL @ the MSI support page for the motherboard. The Gskill F4-3600C17Q-32GTZR kit is also Specifically list.

is this 3rd gen compatible?

Hello there, Thank you for contacting us in regards to your question. According to the manufacturer specifications, the MSI motherboard would only support the Ryzen 3rd generation after a Bios update. This unit would require to have the Bios be updated for 3rd generation support. Hope this helps, Newegg Support
