All boards were tested and BIOS flashed to newest version, F22. 

All boards have good sockets and have a paper over socket to protect the fragile pins. 

These boards support 6th and 7th gen CPUs only. 
These boards also support 1866/2133 MHZ ram speeds. 

These were all tested using (not included, sold separately) i5-6500 6th gen with 2400mhz Crucial memory. 

Comes with the IO shield as pictured. 

These are the GSM model of board - meaning these are the Gigabyte Stable Model, aka "Business Class" version of the GA-Q170M-D3H board.
