I am pretty sure it's to prevent people from overclocking their cards more than NVidia deems safe for the sales of their most expensive cards.

- ComputerGuru 5y agoIf that were the case then manually setting the clock speed would be supported but it would lock out any speeds higher than the OEM configuration.
- sudosysgen 5y agoNot quite, no. Even manually setting the clock rate would allow for performance improvement as you could lock the card at its boost clock or at least prevent downclocking under load. The only lockout solution is to lock speeds to the base clock completely.
- ComputerGuru 5y agoIt depends on how the card’s speed governor works. Do you set a desired clock rate and then the firmware tries to hold that speed dependent on factors like core temperature or do you set a hard value and the firmware holds that come hell or high water?
- sudosysgen 5y agoFrom how it used to work, the actual frequency was dependent on both the driver and firmware, though the driver used to and probably still can force a certain frequency.
