Hello! I built my first this this weekend and I'm having some problems. When both of the RAM sticks are installed I get nothing, the computer boots and it sounds fine but I don't see anything on the screen and the EZ Debug LEDs for DRAM is lit and every 5 seconds or so it turns off and then the CPU LED turns on for 1 second and then it repeats, the DRAM LED turns on for 5 seconds et.c. But the weird this is that everything works fine with just 1 stick of RAM, I'm using the computer right now and I have been gaming on it since I built it without any problems, I have also checked the temperature and everything is fine. I have tried both RAMs in slot 1 and both works, I have also tried every combination in the 4 slots, but I get the same results.

I googled and I found that there are some people with similar issues and people recommended that you turn up the voltage for the RAM by 0.06, so I did that but it still doesn't work, I have also enabled XMP. I think it might be the PSU because it's the oldest part in the PC and it's not that powerful. Here are the specs:

NVIDIA GeForce GTX 760
Intel Core i5-6600 @ 3.30 GHz
Kingston HyperX Fury DDR4-2666 16GB (2x8GB, but only using 1)
MSI Z170A GAMING PRO
Antec VP550P 550W

I have the same issue with 2x8GB from Crucial at 2400.
Tried the 2 modules one by one in the socket B2. One worked the other doesn't.
Combining them in A2 & B2 doesn't work either. So I presume one module is defective or it's specifications are way off. Will be an RMA.

Yep a bad stick probably. I have reset the mobo to its defaults, but that didn't work either.
So I'll have to return the 2 stick set. Will put my system to rest for a few days :-(
