Bij iXBT Labs hebben ze een artikel gepost met hun GeForce 256 overclocking avonturen. Na het hele systeem in een koelkast gekieperd te hebben kregen ze de videokaart op 150/210MHz.
Let's sum up the obtained results and draw certain conclusions. First we will take 16-bit color. At 1024x768 in normal conditions (chipset frequency increase made 16%, memory - 20%) we managed to improve the performance by 5%, but at 1280x1024 this value reached 10%. In fact, the performance gain was absolutely inadequate to the frequencies increase.
In extreme conditions (chipset frequency increase made 25%, memory - 27%) the card performed 18% faster at 1280x1024, which was also less than we had expected. Why did it happen like that? We think that it is again the system CPU that slows down the whole thing (note: there were no games supporting T&L among those considered).
And what about 32-bit color? Theoretically, the CPU should be powerful enough here and the only thing that may set certain limits is the graphics card and its potential. In normal conditions (chipset frequency increase made 16%, memory - 20%) at 1280x1024 we got a 24% performance gain (at 1024x768 - 12%). Well, now we start to like the situation: it really looks as if such overclocking was worth it.
In extreme conditions (chipset frequency increase made 25%, memory - 27%) at 1280x1024 the performance grew by 38% (at 1024x768 - 18%). To tell the truth, the result was beyond our expectations, however, the gaming performance of the card at 1280x1024 still left much to be desired.
