The overclocking champion returns.
Now it was time for the true test of the N580GTX Lightning. Using MSI Afterburner v2.2.0 beta, I increased the voltage by 131mV and overclocked the card to a stable 985MHz Core clock speeds. That’s an incredible 153Mhz over factory speeds and 213Mhz over reference Nvidia speeds!
The results obviously reflect this bump in performance as well, keeping the N580GTX Lightning head and shoulders above the competition.
The increase in voltage obviously increased the heat output as well, resulting in the rather quiet fans to jump from their regular 1.4K to 2.1K rpm under load. Two of these 9cm fans at those speeds do indeed make a lot of noise. That said, temperatures were still better than my expectations, at a mere 64°C while under load during this overclock. And, the Twin Frozr III is brilliant enough to keep idle temperatures at 29°C and under load (at factory speeds) at an astonishingly low 55 °C!
The best part about the MSI N580GTX Lightning is that despite all of its technical prowess over competitors, it still costs a respectable $480! So, better cooling, powerful overclocking, quiet operations and a price well worth it all makes the MSI N580GTX Lightning one of the best GTX 580 cards in the market.
