Overdrive?

[Abacus]

Anche con l'installazione dei catalyst 4.1 sulla 9600xt, l'overdrive non appare. Ma è previsto veramente anche per le 9600xt?

Dipende dalla marca, da quello che ho sentito ce l'hanno solo le Sapphire e non tutte

- The 9600XT's have an on-die thermal diode, and we are using that for thermal checks and as the reported temperature

- The 9800XTs do not have an on-die thermal diode. They have an on package thermistor and an on-board thermal sensor chip. The thermistor is very close to the ASIC die and the thermal transfer is very close to being constant, so a constant delta is fine.

- We've done HW qualification testing on 9800XT's in various configurations, and we've found that there's a very consistent delta differential between reported thermal data and measure ON DIE temperature.

- We can use the reported thermal data from both sources for OC calibration

- The offset of 20 degrees is an approximation of the temperature differential on 98's, and is only used in the control panel temperature report. This temperature does not need to be exact, it just needs to be roughly accurate, which it is within a degree or two. This was experimentally gathered information

- Future changes might refine this process, as we deem fit. We are constantly developing this technology and from the 9600 onward, we plan to have (not guaranteeing we will though) on die thermal diodes in all of our products and in the future, other much more complex on die thermal logic.
