Crucial Ballistix 2x16GB DDR4-2666 SODIMM 1.2V Kit Review
 

We have successfully tested the Ballistix SODIMM 32GB kit by using the JEDEC timings but not the XMP ones, which means that the speed was limited to 2400MHz but with tighter timings. Even in this case, the performance differences are not very big, considering that the previous kits did come with less tight CASes. Many devices such as laptops and miniPCs do have UEFI BIOSes with very limited options and it is really a matter of luck if you will be able to run at the specified speeds; if the option to select the memory profile appears in BIOS, then you are in luck!
