Noise, overclocking

Ad

GeForce 8800 GT 256

Unfortunately, Zalman’s VF100 doesn’t really appear to be silent at peak. It maintains the same speed all the time, which is quite annoying. It’s regrettable that Gigabyte doesn’t adjust the fan’s speed automatically depending on the workload, nor give users the opportunity to do so via dedicated software or even a variable resistance. One has no choice but to use programs like RivaTuner.

The good news is that all that noise isn’t totally in vain, as the fan is efficient and cools the GPU well, and the memory chips too, as our overclocking shows. As a reminder, original clocks of the 8800 GT 256 MB are set at 600/700 MHz and Gigabyte pushed its version to 700/750 MHz.

On top of that we’ve been able to overclock the card to reach 767 MHz for the GPU (almost as high as the G92 of the 8800 GTS 512 MB and 888 MHz for the memory, meaning a total respective gain of 28 and 27%. Basically the increase in Age of Empires III in 1600*1200 manages to reach 20%!
