Hello,
Just posting this in case others bought the same KIT and had better luck then me.
I had to RMA my CMK32GX4M4B3200C16 because one stick out of four was throwing errors.
Because the retailer did not have the same KIT anymore, they replaced it with CMR32GX4M4C3466C16
I agreed after checking http://dlcdnet.asus.com/pub/ASUS/mb/LGA1151/ROG_MAXIMUS_X_FORMULA/MEMORY_QVL_0108.pdf and saw the KIT as qualified.
CMR32GX4M4C3466C16 is a DDR4 Corsair @3466 Mhz 16-18-18-36 (4x8GB)
At JEDEC spec, the KIT runs just fine.
At XMP tho, the system does not even boot most of the time. When it does, Windows will just freeze without any BSOD and the system will restart.
I also tried manually setting up the speed and timings without XMP. Tried Auto, Mode1 and Mode 2. Loaded BIOS defaults and only enabled XMP. Same story.
I have managed to get the system as stable as I can by setting DRAM Voltage to 1.400 instead of 1.350, but even tho I could run AIDA64 Cache & Memory and RealBench successfully for about 1 hour, Windows starts very slow and a MemTest86 run shows errors after only 4 minutes.
At the moment, I am running the KIT @3200Mhz with 15-15-15-35, 1.350V and so far, it seems stable. MemTest86 does not show any errors.
Not holding my breath, but hoping for a future BIOS update that will actually support this memory KIT as stated on QVL link above.
So I guess the question is: does anyone else have this memory KIT and can run it at XMP spec? Or at least a manual setup at XMP spec?
Maybe I have such bad luck to hit two bad kits in a row?
3200Mhz with 15-15-15-35, 1.350V
Thank you.

Just a quick follow up.
I have opened a ticket with Corsair and I was advised to increase DRAM Voltage up to a max of 1.480V.
Corsair rep said: "Intel recommends up to 5% from stock, which would be 1.48V at most."
I suck at math but 5% from stock, considering "stock" is 1.350 and not 1.200 JEDEC, should be 1.418 not 1.480.
Any hints if DDR4 is safe at 1.480V?

Replaced the KIT with an identical one. Same story.
So, more testing with interesting results.
Tested each stick of RAM, one at a time in A1.
Loaded XMP at 3.466Mhz with 1.350V DDR voltage. Rest Auto.
Each stick in A1 was rock solid. No errors in MemTest86.
Then, I tested two sticks of RAM. Same settings
A1 and B1 rock solid. No errors in MemTest86.
A2 and B2 rock solid. No errors in MemTest86.
Took out the first two sticks and put in the other two.
A1 and B1 rock solid. No errors in MemTest86.
A2 and B2 rock solid. No errors in MemTest86.
Just for fun, with two sticks of RAM in A1 and B1, I setup SA, IO and CPU Standby at 1.000V
Ran AIDA64. Rock solid.
Ran MemTest86. No errors whatsoever.
Setup SA, IO and CPU Stanby back to Auto and inserted all four stick. System did NOT post at all. It kept cutting power and powering up again until it posted in safe mode.
Setup SA, IO and CPU Stanby to 1.000V and same story. No go.
So my conclusion: all four sticks of RAM are OK.
For some reason, Maximus X HERO does not like foursome with my sticks 🙂

I would like to postulate that the QVL list is a bit BS. Either the dep. who does the testing only tests one or two sticks out of every KIT, or they just pick random/popular KITs and paste in QVL.

Opened a ticket with Asus and ordered a Voodoo doll and pins for the people responsible for QVL.
