Picking the best ram

Solution
I recommend the following choices if you can get them.

G.Skill Ripjaws 8GB (2x4) kit Part # F4-2400C15D-8GRR
Kingston HyperX 8GB (2x4) Part # HX424C15FBK2/8
Corsair Vengeance 8GB (2x4) Part # CMK16GX4M2A2400C16 ver:3.31

These kits have been tested and should work out of the box.

It wont display anything so i cant check bios i have done everything on this link:http://www.tomshardware.co.uk/forum/261145-31-perform-steps-posting-post-boot-video-problems. I returned the initial sticks and got the replacements and it still doesn't work. Every time i turn it on i get 3 beeps which im pretty sure signifies bad ram.
 
Motherboard could be the issue too. Can you borrow ram from a friend? If not, get this:

No i don't have anyone that could give me ram.
 


The RAM kit you have chosen, G.Skill - Ripjaws V Series 8GB (2 x 4GB) DDR4-3200 Memory are not suitable for your MB.
Your MB supports DDR4 2400/2133Mhz and does not support 3200MHz.
Go here for the MB QVL. https://www.asrock.com/MB/Intel/B250M-HDV/index.asp#Memory The kits that are listed have been tested and will work.
