System stability was tested running the AIDA64 stability test in conjunction with EVGA's OC Scanner X graphical benchmark running at 1280×1024 resolution and 8x MSAA in stress test mode. All overclocking sessions remained stable for over 4hrs.

With the base clock rolled back even further to its stock 100Mhz speed, we pushed the CPU to a cool 4.7GHz with a 4.5GHz ring bus and 3200MHz memory speeds. With the base clock rolled back to 167MHz, we were able to push the CPU to 4.67GHz with a 4.5GHz ring bus and 2672Mhz memory speeds. The board was able to hit a maximum base clock speed of 267MHz (thanks to the decoupled CPU clock generator of the Z170 board design) with a CPU speed of 4.5GHz, a matching 4.5GHz ring bus speed, and a 2490MHz memory speed. To give a feel for the overclocking performance potential of the Z170-A motherboard, we attempted to push it to known CPU-supported performance parameters with minimal tweaking.
