XMP doesn't boot sometimes

[daninthemix]

I have DDR4-3000 on an Asus Z170-A board and sometimes (one in every four boots, perhaps), it doesn't boot. I just get a black screen, then if I turn off and on again, I get 'overclocking failed', so I enter the BIOS and exit without making any changes and then it boots, with the memory at full speed.

 

Any suggestions?

Dodgy memory controller perhaps? You may just have to run without XMP enabled. You won't lose any performance for it.

The LGA 1151 Processors officially support only up to DDR4-2133 MHz. Anything beyond will require overclocking of the Integrated Memory Controller (IMC).

Memory Types -- DDR4-1866/2133, DDR3L-1333/1600 @ 1.35V

 

On the ASUS Z170-A webpage, under specifications, DDR4 2133 MHz and beyond is considered overclocking.

4 x DIMM, Max. 64GB, DDR4 3400 (O.C.) / 3333 (O.C.) / 3100 (O.C) / 2933 (O.C.) / 2800 (O.C.) / 2666 (O.C.) / 2400 (O.C.) / 2133 (O.C.) MHz Non-ECC, Un-buffered Memory

* Hyper DIMM support is subject to the physical characteristics of individual CPUs.

 

As with overclocking any, it will vary between each part -- even if they are both....i7-6700K CPUs. You are not 100% guaranteed anything with overclocking.

 

Enabling XMP DOES NOT make the memory overclock to be magically stable.
