Question 1

I only see 2 SATA plugins and they're by the "ASRock" heat-sink. Where are the other 2?

Accepted Answer

At the bottom right of the board, you see the two satas, then right above the right most one you see a black box thing. Its two stacked on top of each other facing what would be your hard drive area.

Question 2

will this motherboard work with a Amd FX CPU?

Accepted Answer

No, the FX series of processors uses the AM3+ socket. This ASRock motherboard uses the AM4 socket which is for the Ryzen series of processors.

Question 3

will I be able to use a ryzen 3 1200 cpu with a rx550 in this board?

Accepted Answer

From the ASRock website for the board, your CPU and graphics card should be compatible with the board. Buying compatible memory (also given on the website) may be very important.

Question 4

can i overclock with this board?

Accepted Answer

No. This board uses the A320 Promontory Chipset and DOES NOT support Overclocking. Basic OC is supported on B350 boards. Full overclocking is supported on X370 boards.

Question 5

Will this AsRock Mother board work with Windows 7?

Accepted Answer

Yes, see answers on MB description page:

BEST ANSWER: Windows 7 does not have the drivers built in to it for this platform. You have to create a Windows 7 ISO with the Ryzen drivers in it. The tool is available from most motherboard manufacturers. Afterwards, I was able to get this board and another MSI AM4 board to run Windows 7 just fine.

Question 6

What is the tiny screw that comes with the motherboard in the little bag with a serial number and where does it go?

Accepted Answer

This is for the OnBoard M2 SSD hard drive, to hold it in place, Do not loose it, They are very expensive to replace, $10-$25.00

Question 7

Does this mobo have a wifi card?

Accepted Answer

sorry the motherboard has no wifi on-board

Question 8

Will it support AMD A10-9700 processor ?

Accepted Answer

Yes. The ASRock MB site lists the A10-9700 CPU on the CPU Support List. Also, the A10-9700 CPU is listed as a AM4 socket CPU. 
Hope this helps.

Question 9

Can I put two sticks of 8gb ram in here?

Accepted Answer

I currently have 1 8GB stick of RAM in mine, and 16 GB is well within the limit of the motherboard, so there should be no problem with 2 8GB sticks of RAM.

Question 10

I can not get it to boot with a ryzen 3 1200, there was no bios sticker on the box..   any ideas?

Accepted Answer

If it is booting (power) but you do not see anything.. the likely cause is that the Ryzen 3 1200 does not have on board graphics and requires an add on graphics card.
