My old computer died so I've bought new components assembled them and turn on the power. Nothing happened so notice my surprise that while I was checking my old pc I forgot to check if the psu is ok. Basicly old pc is alive but its still old so...

My new specs.
16GB-Kit G.Skill TridentX PC3-21333U
ASUS Rampage IV Black Edition
Intel Core i7-4930K, 6x 3.40GHz
Thermaltake Frio OCK
Sapphire HD 6770 Lite, 1 GB

Only thing I've brought from my old pc is graphic card. So assemble the computer, turn on the psu and motherboard lights up (on the old psu only 2 lights lighted up). Pressed the start button, fan on the CPU turns for half a turn and then nothing happens and only if if the psu was turned of and on the proces repeats itself. Disconnected all hdd, pull out the ram, graphic in the end only thing that was powered was the motherboard and cpu fan the resoult was still the same. At this time it was running on brothers LC Power 650W. So I borrowed another psu in case this too was faulty (brothers pc works fine with it).

After much much frustration had enough so send the case to service. They discovered that the BIOS needed a reset and that the RAM didn't work properly even after the reset so they had to be calibrated from 2666 to 2133MHz. Even though motherboard had two BIOS and easy to switch between them. Can't imagine why would it be necessary to reset the BIOS when the board is new and the whole series was announced onyl 2 mounts ago. And why is it necessary to dial down RAM speed, if motherboard supports up to 2800MHz.

I had number of asus products and the only problems with them was old age. Up until now every product that i have purchase was basicly plug and play and it worked until it was pushed to far so it ether locked itself or it burned out. In this case I wasn't prepaired for the BIOS hoax so early so I haven't thought that this could be a problem.

So any one els had a simmiler problem with Asus or any other manufacturer. Also if there are other problems with this board would like to know. Thanks
 
The Core I7 4930k supports these RAM speeds DDR3-1333/1600/1866, nothing more, nothing less. You can get faster ram speeds to work, but sometimes it isn't as easy as it sounds, some boards are picky, some CPU's are picky. http://ark.intel.com/products/77780

For the resetting of bios, Well that just happens, They probably use a CPU to test to see if the board works before they box it and ship it off to the retailers and that could be a reason for that.

Yep, anything over DDR3-1866 is officially an overclocked configuration. While the board supports those speeds, it comes down to how good the memory controller on the CPU is at running past its stock binned speeds. Each CPU sample varies in how well it can overclock - so it comes down to luck of the draw with this stuff.
