Sapphire HD5670 Ultimate Edition Review

To overclock the card we used MSI Afterburner as we didn’t want to be limited by the ATI Catalyst Control Center ‘overdrive’ solution.

Considering this is a passively cooled solution we weren't expecting such positive results of 100mhz on the core and 70mhz on the memory giving an effective 4280mhz of bandwidth.

We wanted to recheck temperatures to see how the overclock affected cooler performance.

Only a 4c increase with the overclocked settings. Obviously the Raven 02 chassis is helping with the massive vertical airflow, but even in a lesser chassis would wouldn't imagine these exceeding 70c. Well within safety parameters.

We wanted to see how the overclocked speeds would assist with a demanding engine, so we fired up Crysis again.

Nothing dramatic, but a couple of FPS with this engine really helps, especially with minimum frame rates hovering between 25 and 30.
