Test Rig
For our tests, we used our Test Rig which consists of an EVGA Z370 Micro motherboard, along with and Intel Core i7-8700K (Coffee Lake) and a Zotac GeForce GTX 2070 (8GB GDDR6) graphics card.
* ALL tests are conducted at specified default speeds and settings.
| CPU | Intel Core i7-8700K @ 3.7GHz / Turbo boost 4.3GHz |
| Cooling | Corsair H115i AIO cooler |
| Motherboard | EVGA Z370 Micro |
| Ram | Patriot Viper Steel DDR4-4400 16GB Memory Kit |
| XMP 2.0 profiles | Memory timings : 19-19-19-39 @1.35v (2x8GB) |
| SSD | Patriot Hellfire – 240GB |
| PSU | Cooler Master GXII 750W |
| VGA card | Zotac GeForce RTX 2070 (8GB GDDR6) |
| OS |
Windows 10 |
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.
