ASRock x399 Gaming Pro system wont start red blink

   Hello everyone! 

Proud and almost satisfied user of a Threadripper 2990wx! I received all my computer parts yesterday and builted it right away. Everything went good, installed win10, even tried some software. 
But i noticed in the bios that my ram frequency was not running at the ram frequency specs. So i decided to switch it. And unfortunately after saving and rebooting, the system wont boot up. 
I got a red slow blinking light and thats it.

I'll list all my parts so you are guys aware of my system specs:

ASRock Fatality x399 Pro Gaming
Threadripper 2990wx
NZXT Kraken x62
G.Skill Sniper X Series 32Go (4x8Go) DDR4 3600 MHz CL19
ASUS Geforce GTX 1050Ti Rog Strix
Seasonic PRIME Ultra 1000W Titanium
and a kingston SSD A400 480Go for system and a fractal design XL R2 Pearl for the case.

So i checked online before on this forum and found people trying to flash their system with flashback, or clearing their CMOS, removing the mobo battery.

None of these worked, i've unplugged every parts but it's always the same red slow blinking light that I got...

Any idea guys ?

Thanks you!

	Welcome to the forums. So all you did was change the RAM frequency in the BIOS? If so all you should need to do is clear CMOS to get things back to system defaults. If just pushing the clear CMOS button didn't work you can try this method here: http://forum.asrock.com/forum_posts.asp?TID=630&title=how-to-clear-cmos-via-battery-removal In addition to that, I would also disconnect the system from power (pull the power plug from the wall) and leave it that way for an hour or so. Let us know how it goes and good luck

	Hey thanks for your reply! I've already try both solution with no luck at all... In the end I got to the vendor where i got the parts from. The guy told me it would maybe be RAM, or a bad manipulation of the CPU when I installed it. He say they've seen this happen with another another 2xxx ryzen CPU and the socket got damaged and stopped working........... I'll post whatever they find on the forum, maybe it will help someone! But I'm so frustrated ^^ I did some test one 3D render i'm working and it's like 5x time faster than my actual i7 7700k..... Finger crossed!

	If the CPU is not seated correctly the motherboard will not post, so when you remove the CPU remember that the screw tighten order should be followed and only use the torque star drive that was supplied. You must tighten screws as noted on the hold down plate, if one is not tight the computer will not even get into post.
	If it ain't fixed try a bigger hammer!
