I had 12gb of triple channel ram in my x58    Two 3x2 gb kits bought separately.  Worked like a CHARM.
Tried to use 4 of those dimms in this board and they will simply not work at spec speeds or timings.  So bad that if I try to run them at 1600 the machine goes into a power up loop and the code says no memory installed ( 55 ) 
 
So I am stuck with 1333 ram Until I spend a few hundred dollars on dual channel and EAT 12gb of this stuff ( wasn't cheap!) 
 
Crucial says the MIGHT work but they do no guarantee that triple channel kits will work on dual.... That sounds FISHY to me , it they were their best and they were tested to be that why NOW are they USELESS??
 
HELLLLLP!!!!

Have you tried updating the motherboard BIOS?

Are they on the QVL? Does EVGA have a QVL for the z97 Classified yet is also a good question.

Ok first of all have you tried two at a time? Are you running XMP? Are you running at correct voltage?

No went with all four first , will try that and yes I tried XMP but it won't hold the speed.  I could swear I saw it at 1600 once but at low volts ... they call for 1.65 and I saw 1.49  even tried to slower timings as well .
 
 

Did you set the voltage to 1.65V manually? Did you set all of the timings manually to specs?

The Qualified Vendors List (QVL) will give you an idea of what memory is known, by EVGA, to be compatible with their motherboard. It is best to reference that motherboard against the memory to see if it is known compatible or unknown.

Just because it isn't on the list, doesn't mean it won't work. That just means that it isn't guaranteed by EVGA to be known.

All motherboard companies have these lists. Just simply type the mother board nomenclature in Google and QVL (z97 Classified QVL in this case) and it will give you a direct link.

I have never attempted to utilize triple channel ram in a dual channel setup, so your issues may lie there, or you may be seeing other issues come up due to the age of the memory sticks, if they are older.

Try one dimm at a time, make sure they all work properly to boot, and then attempt to expand to more memory. Take baby steps instead of trying to jump first.

Unfortunately the memory finder app on the Corsair website still doesn't work so I can't find any info for you

Crucial says the MIGHT work but they do no guarantee that triple channel kits will work on dual.... That sounds FISHY to me , it they were their best and they were tested to be that why NOW are they USELESS??

The X58 platform was introduced almost six years ago; yeah it and any top-of-the-line made for it was the best, nothing lasts forever.  Crucial can only guarantee operation on what existed at the time versus you salvaging them for your Z97 today, so nothing fishy about it.  I'm sorry, but your kit isn't a waste or useless since you had use for so many years just because you can't use them anymore.  I know it isn't what you wanted to hear, but it's what we all go through when it is time to change the platform, virtually everything isn't salvageable after so many years.  Maybe this experience will give you less incentive to spend so much if the intent was salvaging for a future build.  DDR4 will be introduced this fall, DDR3 is on the way out and means DDR3 is as advanced as it can possibly get, thus why your older kit may be having trouble being pair with Z97.
 
 
But hey, some folks get lucky; but it depends on what else was tested at the time, i.e. if a particular kit was also tested on a P55 (predecessor to the Z68, Z77, Z87, Z97 line which were all dual-channel).

IMHO, I wouldn't use memory that was designed for three channels.  If you hit an XMP, you could have a potential CPU failure.  Even if you get the rig up and running with no errors, this doesn't mean that it will be stable in the future.  You are better off buying a dual channel memory at a 1.5v spec that is rated for this board.

RAM manufacturers create double-channel and triple-channel packages by grouping together RAM modules that are known to work together. I'm not sure of the details, but I do know that there is a batch number of some kind on each stick.
 
So, right now you have 2 differently matched sets of 3 PC. We'll call them sets A and B. The individual sticks we can call A.1, A.2, A.3, and B.1, B.2, and B.3.
 
Your new motherboard, which uses dual-channel RAM, will have specific slots for each set. Try installing like this, beginning with slot 1 as the one being closest to the CPU:
Slot 1 - A.1
Slot 2 - B.1
Slot 3 - A.2
Slot 3 - B.2
 
Then you have sticks A.3 and B.3 remaining, 4 GB unused. I also recommend against any XMP profiles with triple channel RAM. Try overclocking it manually, using the rated settings. But first get it stable at 1333 (max DDR3 standard speed).
 
Or, you could sell both kits (separately or altogether) on ebay, and buy a 2 x 4 GB kit that is compatible with your motherboard. 8 GB is plenty these days. I bought 16 GB used because it was  good deal, and ended up putting it in my server for the VMs to use and putting my 8 GB stick back in my Z97 board. The most RAM I ever utilized at once was 7.5 GB, and that was with 150 tabs open in IE when trying to complete the EVGA scavenger hunt.

 
SO it WORKED!!  ....................  Sort of.
 
SO I used two of the latest revision  ver 5.2 and loaded XMP and WALA!!!  Tried to put the other two from the second kit Ver 3.2a and Power up loop.    SO I can either have 8 gb 1333 or 4 gb 1600 8 8 8 24  or go buy some ram LOL
 
Funny that the two kits worked flawlessly together in my X58 rig.
 
 I think I am going to have to buy some ram.

Glad it (kind of) worked. It could be that the XMP profile is meant specifically for triple-channel, so when you try to run 4 sticks at XMP, it freaks out. I have no technical data to back this up, and I've never worked with triple-channel RAM, but it's just a hypothesis.
 
You could try disabling XMP, and then manually overclocking the DDR speeds to 1600.
 
But for maximum stability, you could probably sell both of these kits on ebay, and make at least the $80-100 necessary to buy a 2 x 4GB kit off the QVL which run better at lower voltages.

Keep in mind that with RAM speeds, from a gaming perspective, it's pretty much like this:
1333 MHz --> 1600 Mhz = modest increase in performance
1600 MHz --> 1866 MHz = okay, it's a little better
1866 MHz --> 2166 MHz = I think it's faster?
2166 MHz --> 2400+ MHz = Um, why did I pay so much for these?
 
Moral of the story - don't buy 3200 MHz RAM as it's crazy expensive and doesn't help with gaming. 1866 or 2166 is plenty.

 
Thanx again.  I ended up buying   16gb Gskill Tridentx 2400  2x 8 GB    They were actually less on sale than 1866 Corsair Platinum ( By a LARGE margin )  Top it off Newegg was having a extra $20.00 of that I didn't even know about until I was checking out.  I will have it Monday : ))  I will keep everyone posted.
 
NN
 
Final Update....   The TridentX 2400 2x8 sticks went right in , Set XMP and rebooted...  They are running FASSSST and Cool.  I don't think I will ever go 32GB....
