New build, with errors

[5150WS6]

Hi guys,
Thought I did my research but I must have messed up somewhere. Here's what I have:
Asus Rampage Extreme LGA2011 MB
I7-3930K 3.2 Sandy bridge
Dual EVGA GTX 670 04G-P4-3673-KR SLI cards
Dual WD Black 4TB SATA 6.0GB/s HD
Corsair Vengeance 64gb(8.x 8gb) DDR3 1866 memory
Antec 920 CPU liquid cooler

I cannot get it to boot. I get the A2 error code on the mb along with a single beep followed by 4 beep error. I have tried reseating the CPU, memory and video cards. I've tried new SATA cables. I've tried booting with only one video card and tried it in both 16 slots. Still nothing. I never get any signal to the monitor.

Can you guys recommend anything? I'm totally lost as to what to try next.

Thanks for your help!

Try 1 stick of ram in slot D-1, and see if it boots with that. Rotate each of your 8 sticks into that slot, see if any of them fail to boot.

After booting each stick, do a single pass of memtest86+.

Corsair Vengeance ram is known to cause issues with the RIVE.

Check that all power connectors are firmly connected as well. 4pin, 8 pin and 24 pin to mb. Power cables to the video card. This is a common cause.

Also, did you plug in the 4 pin EZ_PLUG_2 connector? You need to plug a floppy drive power connector onto it. It helps provide power to the dimms.

1. Did you connect the 920's cables to the correct CPU FAN Header?

2. And do the fans start spinning when you power up your board?

3. Besides the A2 code on the DEBUG LED, please look at the 4 small QLEDS that are beside the 24 pin power connector. Are any of them lit?

You said you tried a single vid card. Did you try the other, single vid card? Don't forget to plug in the vid cable and turn the monitor on.

I've _never_ needed to plug-in the EZ_PLUG_2 connector for Corsair Vengeance 1.5V RAM on multiple builds with this board.
It won't hurt to plug it in, but I doubt it will have any impact at all in regards to this issue. (It's meant for higher speeds/voltages.)

Also, the only 'issue' with Corsair Vengeance RAM + this board I have encountered is that sometimes automatically setting RAM parameters via XMP may not work if you aren't using matched kits.

See if your ram will pass memtest. Use the link in my sig.

I suspect that your 64GB of vengeance ram are not from one kit and that will take some tweaking. But it can be done. Use the metest86+ as the first point of contact when trying to get a system stable, before you even install OS even.

Man you guys kick ass. Chino actually nailed the first problem. I had the Kulher plugged into the wrong plug. Had it in the opt fan and not the cpu fan. That at least got me into the ROG setup screen where I was going to try to get the fan to go 100% as mentioned in other threads. It did throw a CPU fan error.

After that reboot I'm back to nothing. The only changed was the fan to full, then rebooted. Now I get an 03 code error and it just shuts down. Nothing comes up on the monitor either.

Just to answer some of the other questions too. My ram was all from one matched kit. It got it all at once and as a package deal so it would hopefully have the least amount of issues. But yes, it was all bought together in the same pack from Corsair. All of my plugs and power cords have been checked and rechecked. Including the two into each card and the small 4 pin at the top of the board. All are good there.

My Kuhler is now lit up after changing around some plugs there. So that's new and good. But I'm still getting the 03 code then it shuts down after about 15 seconds. I can't find much of anything on an "03System Agent Initialization before microcode loading" error goes?

That is the reason I suggested you use my guide Memtest86+ If you follow those steps my friend you will work out where the stop is located.

I can not recall if you reported if the single stick of ram allowed you to enter into OS?
