Overclocking The Asus N6600GT x2

More MHz=More Performance

Before we completed our testing, we spent a little time overclocking our matched pair of Asus N6600GTs using the clock frequency slider available in NVIDIA's Forceware drivers after enabling the "Coolbits" tweak. Overclocking video cards in SLI mode is somewhat more difficult than overclocking a single card, however, because your peak overclock will be limited by whichever card overclocks the lowest. Each card is not overclocked individually...

In the end, we were able to wring out an additional 42MHz from the cores (8.4% increase), and an additional 90MHz from the memory (9% increase). While the cards were overclocked, we re-ran a couple of high-resolution tests with anti-aliasing and anisotropic filtering enabled using Doom 3 and Half Life 2. The higher clock speeds got us an extra 1.9 frames per second in Doom 3 (5.1% increase), and 2.34 FPS in Half Life 2 (5.7% increase).

Marco Chiappetta

Marco's interest in computing and technology dates all the way back to his early childhood. Even before being exposed to the Commodore P.E.T. and later the Commodore 64 in the early ‘80s, he was interested in electricity and electronics, and he still has the modded AFX cars and shop-worn soldering irons to prove it. Once he got his hands on his own Commodore 64, however, computing became Marco's passion. Throughout his academic and professional lives, Marco has worked with virtually every major platform from the TRS-80 and Amiga, to today's high end, multi-core servers. Over the years, he has worked in many fields related to technology and computing, including system design, assembly and sales, professional quality assurance testing, and technical writing. In addition to being the Managing Editor here at HotHardware for close to 15 years, Marco is also a freelance writer whose work has been published in a number of PC and technology related print publications and he is a regular fixture on HotHardware’s own Two and a Half Geeks webcast. - Contact: marco(at)hothardware(dot)com
