Questions about ASUS H170-Pro

Yes it is, I set up a computer with it at the beginning of the year

Laut der Herstellerwebsite ja... "ASUS AI Suite 3 offers a brand-new user experience through a clearer and more attractive interface with support for larger monitors. It consolidates all exclusive ASUS features into one simple-to-use package, allowing you to supervise overclocking, energy consumption, fan speeds, voltages and more. This all-in-one app offers diverse and easy to use functionality, with no need to switch back and forth between different utilities." http://www.asus.com/Motherboards/H170-PRO/overview/ ja aber ich empfehle nicht den standard kühler zu nehmen...

No. They can be installed, but the motherboard only supports AMD Crossfire, which means you can use two AMD cards but not two Nvvidia (GTX) cards at the same time. For that, the motherboard would have to support SLI. Greetings Damien

I installed the Corsair Vengeance LPX (2x, 8GB, DDR4-2133, DIMM 288, and they work fine.

This mainboard is designed for Skylake processors with the LGA 1151 socket. However, the 4790K comes from the Haswell Refresh series with the LGA 1150 socket, so this mainboard is not compatible with the 4790K. For overclocking, I would advise a Z chipset. Haswell Refresh: Z97 (LGA 1150) + 4790K or Skylake: Z170 (LGA 1151) + 6700K

This item comes with two SATA cables.
