The RAM modules with 2 x 16GB, 1866 MHz, DDR3-RAM, DIMM are basically suitable for the ASUS Z97-PRO Gamer mainboard in terms of type and capacity, as this supports DDR3-RAM and allows a maximum of 32GB RAM. However, according to official specifications and compatible memory lists, the mainboard usually specifies DDR3 modules with 1333 MHz or 1600 MHz as standard. The 1866 MHz modules could work, but may only run at reduced speed or require a manual setting in the BIOS.

It is important that the mainboard supports DIMM modules (desktop RAM), which is the case with the modules mentioned. The information that the RAM modules are compatible with Mac Pro Late 2013 does not exclude their use in other systems, but only indicates additional compatibility.

To summarise: The modules should be technically compatible as they are DDR3 DIMM with 1866 MHz and 32GB total size, which is the same as the ASUS Z97-PRO Gamer. However, the modules may not run at full 1866 MHz speed and a BIOS adjustment may be necessary. A 100% proof of compatibility specifically for this motherboard is not available, but the basic specifications match.
