Hey guys!

I have a new setup (i5 4690, asrock z97 pro 3 (updated bios to 2.1 after i got the ram problem, no success). The ram I'm using 2x:
http://www.mindfactory.de/product_info.php/8GB-Kingston-ValueRAM-DDR3-1600-DIMM-CL11-Dual-Kit_815417.html
I tried it with a new cooler at first (be quiet shadow rock 2):

Ram channel b in my pc isnt working.
I get into bios with a ram in slot a1 or a2 or a1 + a2 (but thats not dual)
Whats not working is: a1 + b1 (dual 1) a2 + b2 (dual 2) or all 4. I also tried everyone individually and they allwork on either a1 + a2 or individually on a1 or a2

Then I updated bios to 2.1 - not working

Then I deinstalled cooler and tried standard cpu cooler from intel...
same Problem

So Mainboard or CPU broken? or what can I do?

Greets...

Nope itsn't reading them at all.. pc is not starting up

If I put 1 ram in a1 (1st blue) it works
If i put 1 ram in a2 (1st black) it works
If i put 2 rams in a1 + a2 (blue + black) it works -> not dual of course
If i put 1 ram in b1 or b2 or b1 + b2 or a1 + b1 or a2 + b2 pc is not starting :)
