Nvidia’s GeForce GTX 480 has a default core clock speed of 700 MHz. The shader clock speed is 1400 MHz, while the memory clock speed is 3696 MHz. However, it was rumored that the clock speeds that Nvidia were trying to hit were much higher. What if you could attain those clock speeds? What would its performance have been? Guru3D takes a look at adding more GPU voltage to the GeForce GTX 480 and overclocking the GPU core. The problem with this is that it adds a considerable amount of heat. Therefore, they recommend either setting the fan at 100%, or to watercool the card. What did they achieve? They were able to achieve a core clock of 857MHz, a corresponding shader clock of 1713MHz and a memory clock of 4512MHz. Hit the link below to see how that translates into high framerates in games.

The GeForce GTX 400 series definitely has been topic of much discussion. Though extremely powerful this graphics card runs hot and is rather loud. Now these sure are lacklustre factors .. but that doesn’t mean the product doesn’t have any further potential. Contrary as today’s article will show there’s in fact a lot of additional performance to be found in the GeForce GTX 480, that’s if you know how to tweak it properly.
