Asus Prime Z270-K won't boot with added memory

I am having boot and crash issues with my home build.

Since finishing my build several months ago I have been experiencing random crashes. With messages ranging from Driver, Kernal and Memory Errors. When I am doing no more than streaming hulu and using the internet. I have tried updating every driver manually and installed the Patch for the i5 issues. And still experiencing crashes I decided to try upgrading my memory.

I originally had a
Gigabyte Z270-hd3 mobo
2x 4 GB of Ballistix sport RAM
Intel i5 7500 CPU
Windows 10
MSI Geforce GT 710

When I tried to upgrade using 2x 8GB of Ballistix sports RAM (both by themselves or together with 2x4gb) I couldn’t get it to boot. I did some research and found there are some issues with the Gigabyte Z270 mobo and memory. So decided to see if a different mobo would work better.
I purchased a ASUS Prime Z270-k mobo

After installing and connecting all components, I couldn’t get it to boot until I had only one 4GB stick installed. After that I can get to the bios and get a full boot. I added the other 4GB stick and could get to the same. But when I insert only one 8GB stick on the mobo (no 4gbs), I can only get to Bios when I save and exit the bios either with XMP or default on. It will not boot. And if I have two 8GB stick I can’t even get to the bios

How can I get my system to recognize and boot with at least the 2x 8gb sticks? Or with all 4 sticks of RAM?

Since same issue with two motherboards, I'd RMA the CPU, to rule it out.

well that is exactly what was wrong, was able to exchange my CPU and When i dropped the new one in it booted right up with all the RAM inserted.
