THE ZEUS DDR4 16GB 3200MHZ CL20
The ZEUS line lacks heatspreaders and so that may affect its overclocking potential.
Of course, the fact that they lack heatspreaders means they are low-profile and ideal for use in for example mini-ITX and micro-ATX systems.
Typically, a small sticker located at the rear informs you of the frequency, the timings and the voltage required.
Being very thin means, you can mount and unmount these modules with ease (at least easier than larger ones).
Since these modules have no heatspreaders on them i decided to use the open test bench Z390 DARK configuration (same BIOS configuration as the main one).
Here you can see info on this kit via the popular Thaiphoon Burner software.
