EVGA GeForce GTX 970 SSC ACX 2.0+ 4GB Overclocking Results

Using EVGA's excellent Precision X software, we began as ever by ramping up the power and temperature limits to their maximums – 110 percent and 91°C.

This allowed us to add 130MHz to the core, for a base clock of 1,320MHz, an 11 percent increase. This also represents a huge 26 percent increase over reference speeds. The boost clock was rated at 1,472MHz, and the card actually managed a little higher than this, hitting a constant 1,497MHz under load. We've seen other GTX 970s boost to over 1,500MHz a fair few times, but this is still an excellent result.

The memory overclocked very nicely as well, all the way to a staggering 8.1GHz, which is a 16 percent boost. It was even bench-stable at 8.2GHz, but not without artifacts, so we dialled it back a step.
