Overclocking Results

In order to overclock these cards, we used a vendor agnostic version of Sapphire's TRIXX software which allowed us to bypass the hard limits of 1100MHz on the core and 6.3GHz of memory speed. Unfortunately, neither the reference nor the HIS card were quite able to get up to those levels without voltage increases but we decided against overvolting in order to keep a level playing field. In addition, the fan speed profiles were left at their default values.

While we weren't quite able to get all the way up to 1.1GHz / 6.3Gbps, both of these cards were able to hit very respectable clock speeds. The performance increase was of course impressive, with framerates that were equal to or better than the HD 7970. Just remember that the results you see below are what we consider 24/7 stable and have been used for at least 6 hours of gaming to ensure stability.

Final Clock Speeds

Reference HD 7950:

Core: 1011MHz
Memory: 5948MHz (QDR)

HIS HD 7950:

Core: 998MHz
Memory: 5964MHz (QDR)
