Sapphire Radeon HD 7950 3GB OC Edition Review: GCN For A Better Price

The Sapphire HD 7950 is clocked at 900MHz on the core, 100MHz higher than the reference design (800MHz). Default VID of our card is 0.965V with a ASIC quality of 78.2%. Like the HD 7970, it also has PCIe 3.0 support which is currently only available on the SNB-E/X79 platform.

CCC Overdrive allows the clocks to be raised at high as 1100MHz and 1575MHz on the core and memory respectively. More on overclocking later…

 

Sapphire TriXX overclocking utility was not bundled with the board, but we had no problem downloading and getting it to work from their support website

 

Things are a lot more interesting on this tab than what CCC Overdrive offers – besides the extended clocks we could also set voltages up to 1300mV

 

Users can define custom fan profiles depending on acoustic needs or set a fixed fan speed

 

The ability to disable ULPS (without manually editing the registry) is certainly a nice feature to prevent idle bugs on Crossfire setups
