Hello.

I wake up ~30 minutes before and try to boot my system .... well it doesnt boot.
So i sitting on my desk, eat my toast and was looking, what it does.

So my PC turn the power on, it runs to a point and goes out. Silence .... then my PC turn the power on and repeat.

I take a look at the Status LED's and i see, my pc stop running at the code "66"
Handbook says: "CPU DXD initialisation started"
I dont know, what this means. And in the Handbook, there are no more informations.

To find out, what is wrong, i removed all Dimms. Just for testing. I start to insert one Dimm, turn it on .... and it worked?!?
So i tested all my eight dimms, but when i insert allways one single dimm, the system boots fine.

Here comes the miracle .... when i add more then 4 Dimms the system wont boot. And yes, i checked the installation order and change the dimms for other dimms, it still wont boot with 6 or 8 dimms.


Here is my system:

CPU: Intel I7 4930K, not overcloecked
Graphic: 2x GTX Titan in SLI
Ram: 8x Kingstone HyperX 1866Mhz, 4 GB
HDD: 2x Kindstone SSD 240GB
HDD: 1x Kingstone SSD 120 GB "System"
HDD: 2x 1TB HDD
Mainboard: Asus Rampage 4 Extreme
and a extra soundcard, because i had this from my system before

Maybe some of you had the same problem, or know a solution. At the moment i run this PC with 4 dimms and write this post .....

The next what i do is updating my bios .... maybe this will work


Edit .... nothing changed. Still not working. I dont know what to do. Turn the PC yesterday off, stand up and didnt work ....

Solution
I'd guess the DRAM was purchased in 2 or more packages and simply it all doesn't want to play nice. Try raising the DRAM voltage + 0.06 and set the VCCSA voltage to 1.25 and try
