Question Overclocked ram now blackscreen

Did you reset the CMOS (i.e. pulling the motherboard battery for 30 seconds and replacing) so you can try to have a working system again?
I pulled the battery out for about 20 to 30 seconds and it seemed to do something but it's still not working. When I overclocked it the led strip behind my monitor turned white instead of red for some reason. When I did this it turned red again but nothing else happened
 
Just as a reference, I have G.Skill TridentZ 3200 C16 RAM that I run at 3400 MHz but it took me quite a while and a lot of testing to get it to run at that speed and still be stable.
If you really do want to OC your RAM you need to take the time to read a few RAM OCing Guides.
Then Google the DRAM Calculator for Ryzen and Thaiphoon Burner which when used properly can help you safely OC your RAM.
