Overclocking - Spectra 2500 vs. STB Velocity 4400 AGP

With the plain heatsink the Velocity 4400 simply cannot compete with the Spectra's onboard fan for overclocking. At their default speed, both boards run at 90 MHz core / 110 MHz memory clock. When you bump up the speed of the already hot Velocity 4400 to 95 MHz core / 115 MHz memory the card already becomes unstable. The Spectra, however, runs fine at even 100 MHz core / 115 MHz memory -for me- without any problems and little heat increase. If you add some monster cooling as suggested in my TNT cooling article, the STB can run even faster than the Canopus, but at a price. Keep in mind that the STB uses higher quality ram so the memory clock will probably not exceed 120 MHz on the Spectra boards.
