Debug led #51 help?

[Kazooey]

I just upgraded my system (a lot). i got an i7 4790k paired with an h100i all in one liquid cooler. I also upgraded to a gigabyte z87x-ud5th motherboard. On first boot I got the debug led 51. the manual said that this is a memory initialization error. I opened up a ticket with gigabyte and they said to check for bent pins. Nothing. I moved my Ram into different slots, and still the same debug led on startup. any ideas?

is the ram seated right and try with just one stick you might have fried one when moving it

Tried that multiple times with both sticks. then I grabbed my bros ram, all 16 gigs, then i tried 8, then 4, all still came up with 51
