Just made a build. (Not much experience) and I got everything plugged in but no display and I get an a2 error which means ide detect? I also got that code with just the mobo cpu and cooler and ram I'm pretty sure.

Intel i7 7700k
Geforce 1080 ti
16x2 corsair vengeance Lpx 3200mhz

I have the same motherboard that you have and for me it works like a charm.

But this is a bit strange I have to admit that.


Just to make sure:

Strip the system down to a bare minimum, like 1 ram module only, no GPU and run on the CPU`s internal graphics.
Double check that everything is plugged in correct and that you are not creating a short circuit like the backside of the motherboard is touching the motherboard tray of the case.

I got the error code still with just cpu and cooler and ram. Tried that before putting it in. Thinking it might be because nothing else was plugged in. I just got passed the error code 53 to land in this one. When it starts it goes through all sorts of numbers and it goes through the vga and those other lights and stays on boot red light a2. I don't see my mobo touching my case either. It has to either be my cpu or mobo. I think my new ram is fine. Been stuck trying to make this work for almost 2 weeks. :(

I had problems in the start myself (dont remember Qcode) and it was all down to 1 faulty ram stick out of 4.
But I dont recall getting the a2 code.

Have you even tryed a different ram module? and tryed different DIMM slots?

I just got something on screen. Says what I have hooked up. And says enter setup to recover bios setting. After setting up Intel r optane memory or the raid configuration was built, sata mode selection must be changed to raid mode to avoid unknown issues.

a2 is something to do with the sata you are correct, but it is better to check than not to check.

But if you have tryed every sata port on the motherboard, the only thing is to try an different hard drive.

hmm.. Now I am starting to belive it is your BIOS that is faulty here.

What should I do next? I have very very little experience in bios. I can go through bios. Haven't tried exiting yet and seeing what happens. I can't find this raid configuration either. I feel like I'm right there now to getting it running

It's sitting in bios. I have to leave to work here in a second. Yeah it said I had to configure that. And I think I'm good after that.
