ga-990fx-ud3 4x4gb notbooting

[wilcorook]

Hi
I upgraded my ram to 16gb(4x4) but i can't get it to boot, not even get in the bios. There are no beeps or anything, the fans do spin tough. If I remove 2 sticks of ram I can boot normally and everything works just fine.
My full specs are:
CPU: FX8350
MOBO: GA-990FX-UD3
RAM: 16Gb Corsair vengeance lp
GPU: Gigabyte GTX 970 windforce
PSU: Coolermaster G650M
SSD: KIngston V300 120GB
HDD: Seagate Barracude 2TB

Please help I have no idea what's wrong

Rule out that the extra two sticks of RAM are good, install only those. If it boots with those, that means your RAM is good. Heck, maybe set to BIOS defaults and try again? Try blowing out previously empty memory slots with canned air?

All the sticks are fully functional. And so are the slots. The problemen is that when all 4 dimms are installed it gives a blackscreen and nothing else, no splashscreen or annything
