Overclocking
While there exists a number of other 7800 GTX-based
cards that come pre-overclocked in the market, those cards all utilize the
exact same components as factory-clocked cards. Gigabyte’s 7800 GTX comes
with the stock frequencies of 430 MHz core and 1200 MHz DDR3 memory. For
added performance, I decided to check for the highest possible overclock by
utilizing the “Coolbits” function and testing for optimal clock
frequencies. To verify its stability, I ran a couple of benchmarks and
recorded the results to illustrate the speed benefits of overclocking the
7800 GTX. I was able to achieve a maximum overclock of 465 MHz core and
1260 MHz memory.
While not as high as some of the special
pre-overclocked cards in the market, the Gigabyte 7800 GTX showed
considerable improvements in the graphically demanding Chronicles of Riddick
and Half-Life 2 benchmarks. 3dMark03 and 3dMark05 also benefited from an
increase frequencies. Although the performance may seem quite small, any
free increase in performance is better than nothing and increased clock
speeds also contribute to higher minimum frame rate. In today’s competitive
environment among both avid gamers and overclockers, almost every single
frame counts, and its good to know Gigabyte’s 7800 GTX provides a little
more headroom in the overclocking department.
