So bear with me a bit, its been most of a month since I had a working desktop thanks to the X99 FTW..
 
First, I've been building computers for 19 years and I have never had as much trouble as I have with this upgrade.
 
Old power supply died, so I upgraded..
 
Intel i7 5820k
X99 FTW
32GB Crucial Ballistix (4x8GB)
 
However, the new board would not complete POST. It would stop every time on code b7. Reading the forums here, i tried mix and match with the memory, without memory it stopped on code 53 (expected) but I could never get past b7, and never got any video output. Reseated the CPU, there were no bent pins. Also, the motherboard would not respond to the case power button, it would turn on if the power supply switch was on and would not turn off til the switch was turned off.
 
Not having another LGA 2011v3 board/CPU to test with, I sent both motherboard and CPU back to Newegg for replacement (Yay, Newegg customer service).
 
In the meantime, I loaded all my components back onto the old motherboard( i7 970, Evga FTW3 X58)with the new power supply and everything works perfectly. So I know for a fact that all the peripherals are fine.
 
Got the replacement CPU and board, installed everything again and this one has exactly the same problem. Stops on error code b7, no video out. Tried mix and match with the memory, no POST. Tried reseating the CPU, no POST. One memory stick installed in slot 1, no peripherals, no POST. Took a macro photo of the empty CPU socket with my camera, blew it up on the big monitor and verified there are no bent pins. Reinstalled everything. Still nothing, no POST, no video out, nothing.
 
At least this one responds to the case power button, but that's not much help.
 
So I'm two boards and two CPUs into this (and out quite a lot of money) and doing no better than when I started.
 
Reading these forums, I keep seeing that people have the same problems again and again.
 
Are these boards just THAT unreliable?

You don't have other memory to try, at least 2 DIMM with 4GB.
On my board I have different BIOS on position 2, did you tried to play with that. 
Tried to disable XMP too and to set speed from specification or lower and same latency manual.
 

At the moment, no other memory to try, but that would mean that all 4 brand-new Crucial DIMMS are bad. This is not likely.
Both BIOSs do the same thing.
It isn't possible to change BIOS settings because there is no video output. POST does not complete.

hello
 
have you try only  one dim on slot 1 , boot ?
gpu is on slot 1pcie and nothing in  others pcie ?
 

Yes, see OP.
Yes.

Which memory slots did you fill in? 

There is no configuration of memory slots/DIMMS that results in a complete POST. Not even with a single DIMM in slot 1. Not even with each of 4 different DIMMs tried individually in slot 1. Not even with any two DIMMs in slots 1 and 3. In all instances it stops on error b7.
 
I covered this in the OP.

I didn't see it mentioned anywhere unless I missed it, but I assume you're using DDR4 memory?

Yes. Also, no other type is going to physically fit in the slots.

Its very hard to believe that all four of them are individually bad. Also the problems with the two boards are slightly different, the first one had power-on issues as well. I"m trying to find another stick of RAM to test with, but I'm much more inclined to believe that this is an issue with the board itself (again) based upon what I'm seeing and what I've read about these boards around the internet.

It makes sense to me to see if you can rule it (memory) out or not as the cause.
 
Good luck and hope that it's and it works out for you...

Feed it a set of transformer dimms (gskill ripjaws ), got the 2666 15-15-15-35 tuned down to 12-12-13-27 with a little juice, good kit that runs super cool.  This is the most stable platform I've worked on to date, be patient and you'll probably be rewarded.  Any chance you try to hit reset cmos button before firing it up?  Dumb question, but might help. 

I've used Mushkin for years and never had a problem, so I'm going back to them. Their DDR4 wasn't available at the time of the original purchase, but it is now. Newegg approved the refund so I'm just waiting for it to post on my account before buying the new memory. Should be back with it next week.
 
And yes, reset CMOS during testing and no change.

Did the board beep at d6 and then became b7 ?
 

No POST beeps at all.

New memory arrives Tuesday, we'll see how it goes.

I'm curious about this as well. A very strange problem indeed.

diabloss
when you inserting the dimm modules in slots you have to mak....  **Snip**

Trust me, I know what I'm doing.

Short version:
 
This memory does not work in this board:

This memory does:

Long version:
With the Crucial memory, any single stick in any slot was no POST no video out. With the Mushkin memory, it POSTed on the first first try with one stick in and on the second try fully loaded. Maybe CAS 16 is just too slow and the board wouldn't cooperate.
 
Case closed.

What?  I have this memory from Crucial that was given together from one of EVGA's promotions with the X99 classified.  Ironically I had a MB blowout which I don't think had anything to do with it.

Strange, but glad to hear you're up and running...
