ATI’s Overdrive 4 plans
techPowerUp! has some information on Overdrive 4 which is due in ATI’s next Catalyst driver release in March:
"Previously you could only overclock your GPU core with Overdrive, and only by a rather small amount. Now you can overclock both core and memory and the frequency range will be increased to 75% of the next higher class product. For example the X800 Non-Pro (400 Mhz / 350 Mhz) could be overclocked up to 456 Mhz Core (400 + (475-400) * 0.75). The memory overclock would be 425 Mhz (350 + (450-350) * 0.75)."
