I had problems  (see other post) with my X99 FTW K board.   I have had my replacement from advanced RMA since Friday (Nov 18th).   I thought I would make sure everything was running well before I attempted to overclock.  
 
The board before had bios v 2.01 and I got a 95 post code error when I set XMP profile without any other overclock (cpu).  Then I flashed and killed the board twice (both bios's).   The new board still has v 2.01 but it is supposed to support DDR4 3200mhz which is what I have.  Here is a list of what I am running.
 
CPU - 5820k (previously oc'ed to 4.4ghz - 4.6ghz on Asrock board) @ 1.31-1.35 volts
RAM - 8 - 8gb sticks of Corsair 3200mhz LED Vengeance (CMU32GX4M4C3200C16R) 16-18-18-36 @3200mhz 1.35v
GPU - 2 Evga 1070 GTX FTW Hybrid non oc'ed at the moment
HDD - 2 WD 2TB Green
SSD - Corsair 256gb Cache drive
SSD - Samsung 950 Pro M.2 NVME
PSU - Corsair RM1000i
Cooling - Corsair H115i
USB 2 Keyboard 1 Mouse 1 UPS 1 webcam 2
Ethernet 2
 
So far when I do anything to RAM (ie set XMP profile) or adjust the CPU multiplier even 100mhz from stock the pc reboots then gives me an error 95.
 
I tried 37,38,39,40,44 ghz so far with adaptive voltage trying to get 1.3v and all resulted in the same thing.  I read the overclocking guide and none of the suggested settings seemed to help.
 
I am beginning to think its a ram issue but unsure.  The ram is dual/quad channel.  
 
 
Voltage prior to overclocking all seem ok.
 
Any guidance would greatly be appreciated.   I have to reset the bios with the error 95 and turn on the m.2 slot and set the boot order again every time I try and overclock.  Just annoying but I am sure I will eventually get it and see what I am doing wrong.

Make sure the BCLK is set to 100 Mhz when you are overclocking, as the RAM XMP profiles are likely to change it to something like 127.34 Mhz
(which can cause instabilities on Haswell-E CPUs).

you messed with your "system agent voltage" in the bios yet? 
 
you want to increase it to around 0.350-0.450 that should sort it out
 
when i first got my X99e-ws i got so frustrated i kicked a hole in the side panel of my case, but it was a simple fix increasing the voltage on the RAM, 
 
 

Gotcha .  I just watched a review from paul's hardware on the initial x99 classified and he set xmp and it went to 125 strap.

Thank you going back in to set it.  I had previously never touched it.

 
you also want to set your memory timings and voltage in the Bios manually, i don't know how your Bios looks but when you find where to set the timings scroll down that's where you put your mem voltage not anywhere else,
 
tbh, i found better results in keeping to the 100 strap because of the "adaptive" voltage till i had figured out the board and it's various voltages now it happily trundles along on the 125strap with the XMP enabled and all my memory showing correctly nae bother at all..
 
also what people seem to forget with gfx cards or motherboards they need time to bed in, stick with 100strap, get your volts a sorted then strap the mofo to 125 with the XMP on 
 
it's a asus x99 i have but all x99 boards are really the same.
 
 

I ran at bclk of 100 right now.  I was able to set the xmp profile and get 3200mhz out of my ram without any overclock on the cpu.  But every time I touch anything cpu related I get a code 95 error.   will eventually sort it out.

Could be the CPU doesn't like any OCing when you've OC'd the RAM.  You could have one of those CPUs.   Have you tried OCing the CPU without OCing the RAM?  Try that and see how far you get.  It will take some time so take your time on this.

what's your uncore set to?
 
reducing your uncore should help a lot with clocking up your CPU
 
you should have minimum and maximum setting, minimum being "auto" then play with the maximum setting and remember it's all about finding the right volts to go with the clocks, start @1.30 for uncore and work down, 1.25 for the CPU and work up, one thing to remember is to avoid going above the hallowed 1.4v :D 
 
softly softly catchee monkey :D

I have had the cpu to 4.4-4.6ghz on 32gb of 2666mhz and 64gb 2400mhz on another board.
 
So far I am really lacking on what needs changing.
 
I can get the memory to 3200mhz by changing the bclk to 100 (literally typing 100.00) and xmp in memory tab to profile 1.
 
Any cpu adjustment just seems to give me error code 95 and fails to boot.
 



 
These are the steps I am taking.  
Disable EIST
Disable Turbo
 
Set multi from auto to manual
 
Bclk to 100.00
 
CPU voltage to Adaptive (tried override as well)
 
CPU target to 1.3v
 
Cpu offset to 250mv+
 
 
Left everything else on auto and tried various other things like ring voltage to the same as cpu voltage.
