Asus R9 390X STRIX DC3 OC 8GB Review

We know that the R9 390X has more headroom in it than reference or board partner speeds would suggest, so we pushed to see how far we could overclock Asus' R9 390X STRIX DC3 OC card.

We managed to obtain a decent overclock to 1150MHz on the GPU core and 1700MHz (6.8Gbps effective) for the 8GB of GDDR5 memory. These settings garnered a solid performance increase of 10% in GTA V at 4K, and a 7% higher graphics score in 3DMark.

Overclocking the card increases the GPU temperature to around 88C and the fans have to work harder – running at 48%. Power consumption is also increased significantly, to 562W for the entire test system.
