Installation

The EVGA Z370 Micro motherboard only has 2 DIMM slots, so once we installed the pair of Patriot Viper Steel memory modules, there’s no room to add any more. 

 

BIOS Setup

We used the EVGA Z370 Micro motherboard … and It couldn’t be simplier. Selecting XMP Profiles will give you a memory to 4133 MHz by default. However, when I tried to set the speed to 4400 MHz, it failed to boot 🙂

I’d expect you’ll be able run these memory module at the rated speed of DDR4-4400 using the Asus ROG Maximus XI Apex motherboard. 

Using the EVGA Z370 Micro motherboard, the furthest I could take these memory modules to was DDR4-4300, which was close enough. DIMM voltage and DRAM timings were left on AUTO and untouched. There’s no real need to adjust anything here.

 

CPU-Z and SPD Information

CPU-Z reports the ram speed at 2150MHz, that’s DDR4-4300 spec … 

Ram timings is correctly shown at 19-19-19-39. Notice the memory ICs are made by Samsung and they are certified XMP 2.0.
