Review: Best price for value motherboard!! - Everything is perfect on this motherboard. It has so many fan headers (6) to mount on your pc case. It also comes with a pretty useful manual and a sick MSi dragon sticket. Love it!!!
Review: Slow boot / Post - The only reason I give this a 4 stars and not 5, is due to the long time it takes to start. But once the computer started, the PC runs fine. I searched the web for a solution as well as contacted MSI and we are in the process to try and speed it up. Takes around 2 min 44 seconds to boot. I you do not mind waiting to boot, then this is defenatly the mobo for you. I installed the AMD 3900X cpu with 32Gb RAM. It is lightning fast and happy with it. Just little sad about the long boot / post

## Questions & Answers

**Q: How do you get WiFi to this motherboard**
A: Buy a WiFi PCIe Card! You can buy a wifi 6 card for between twenty and forty bucks and they take minutes to fit. If you don't need an ultra-fast and capable wifi connection you can also buy a wifi dongle that plugs into a spare USB port (preferably a USB 3.0 port) however I'd strongly recommend a PCIe plug-in card.

**Q: Will this support Ryzen 7 3700x out of the box?**
A: Yes it does finished my build with it yesterday

**Q: Can it support mvme ssd?**
A: It has support for two NVMe devices although only the first supports PCIe 4. The second supports PCIe 3. I use both slots with each having a capacity of 1tb. Either slot can support both PCIe 3 and 4 devices but you only get the fastest performance matching a PCIe 4 drive to the first slot. The X570 motherboard offers 2 slots and both are PCIe 4 capable.

**Q: Does this mobo fit a musetex phantom atx mid tower case?**
A: That depends on whether the Phantom ATX mid tower case can
accommodate a motherboard with the dimensions 12 in. x 9.6 in.
(30.5 cm x 24.4 cm).

### ⭐⭐⭐⭐⭐ Perfect motherboard for 3000 series
*by F***L on 28 September 2020*

Paired this with a AMD Ryzen 7 3700x CPU and it was a simple plug and play. No bios updates required and everything ran perfect. Also its future proof so will be able to upgrade to the Ryzen 4000 series when it releases later this year. Good VRMs and great boost clocks. Also love the dual M2 slots.
