Nvidia’s GeForce GTX 470 has a default core clock speed of 600 MHz. The shader clock speed is 1215 MHz, while the memory clock speed is 3348 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 470 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 775MHz, a corresponding shader clock of 1548MHz and a memory clock of 3400MHz. Hit the link below to see how that translates into high framerates in games.
A couple of days ago we had a peek at the GeForce GTX 480 and how well it overclocked in combo with a little extra GPU voltage. The results have shown fabulous potential.
Of course there’s another card, the GeForce GTX 470. Last Friday we finished up an internal build of MSI’s AfterBurner 1.6.0 beta 5 and here we where able to successfully implement voltage adjustment for the GTX 470 cards as well, this build will be released on Monday. So today we’ll again touch the holy grail over overclocking, voltage tweaking.
