Gigabyte Z270N-WIFI + HyperX Predator DDR4, 2x8GB, 3000MHz - RAM issue

[nvent]

Hi,
I have problem with RAM memory. Bug = computer runs for 10 seconds and resets (in loop).
Gigabyte Z270N-WIFI has 2 memory sockets - DDR4_1 nad DDR4_2.
I have memory HyperX Predator DDR4, 2x8GB, 3000MHz.
Now:
Memory at DDR4_1 and DDR4_2 = bug
Memory at DDR4_1 = bug
Memory at DDR4_2 = computer is booting properly

Memory is OK, I tested both on DDR4_2.
I think CPU memory controller is OK, because I bought CPU (Intel Core i5 7600K) 2 days ago.

How can i solve this problem?

Is your specific memory kit on the QVL for your board?  DDR4_2 & 1 are the recommended slots for 2 DIMM config. 

Your CPU supports DDR4-2133/2400, DDR3L-1333/1600 @ 1.35V natively. 

You didn't provide the part number of your kit but the specs I found on Kinston's site show:

•JEDEC: DDR4-2400 CL17-17-17 @1.2V
•XMP Profile #1: DDR4-3000 CL15-17-17 @1.35V
•XMP Profile #2: DDR4-2666 CL15-17-17 @1.35V

I'd try enabling XMP Profile #1 with one stick, save, then install 2 DIMMs in recommended slots and retest.  If that fails, I would manually set memory timings to CL15-17-17 @1.35V and retest.

3000Mhz memory requires O.C. per your boards specs;

3.Support for DDR4 4000(O.C.) / 3866(O.C.) / 3800(O.C.) / 3733(O.C.) / 3666(O.C.) / 3600(O.C.) / 3466(O.C.) / 3400(O.C.) / 3333(O.C.) / 3300(O.C.) / 3200(O.C.) / 3000(O.C.) / 2800(O.C.) / 2666(O.C.) / 2400 / 2133 MHz memory modules

If you don't want this hassle, purchase RAM from the QVL that runs at 2133/2400 and XMP will work.

It's HX430C15PB3K2/16 memory.

I've given you the information you need to determine next steps. 

HX430C15PB3K2/16

If its on the QVL, chances are you can make it work using modest OC and manual settings.

If not on the QVL, you have a 50/50 chance of success using manual settings.

If you don't want the hassle, purchase QVL RAM of 2133/2400 spec.

I tried change settings, but it's not working anyway.

Memory at DDR4_1 and DDR4_2 = bug
Memory at only DDR4_1 = bug
Memory at only DDR4_2 = computer is booting properly

But look - second socket is working (DDR4_2) with this memory and gets automatically settings. So memory is OK. First socket doesn't work even with one memory. I think motherboard has broken first socket. Maybe I will send it back and buy new one.

Something to consider.  A defective slot, DIMM, bent pins in CPU socket or defective CPU would probably result in code 55, CPU initialization failure or other error code.

A reboot loop without error can have more than one cause...  hardware incompatibility, incorrect BIOS settings, memory issue, power problem, ground, or BIOS failure.  While a defect is possible, I'd test with different RAM before concluding the board is defective.

I would send the motherboard back and get another brand.
