Regular readers will already know that KitGuru broke this news last week, but AMD have now made their official statement regarding the HD6990 warranty, when using the ‘overclocked’ bios profile.
This statement is provided In order to clarify questions around AMD’s product warranty for hardware overclocked AMD Radeon™ HD 6990 graphics cards.
Each AMD Radeon HD 6990 graphics card come with a hardware switch that, if toggled, activates a pre-flashed “overclocked” BIOS. Toggling this switch to the overclocked setting has the same functionality and effect as common software overclocking and overvolting utilities, will run the HD 6990 outside of the warrantied specification, and will require more electrical current than some power supplies are designed to deliver.
As with software overclocking, damages caused by use of an AMD graphics card outside of the warrantied specification are not covered under AMD’s product warranty. This is in line with industry practice relating to overclocking or running a product out of warrantied specification.
To ensure end users understand this before using the switch to activate the overclocked BIOS, every HD 6990 graphics card has a yellow warning sticker covering this switch. The switch is not user accessible without removing this sticker. The HD 6990 user guide and support website each contain an overclocking warning message similar to the AMD Overdrive software warning. An example of both the sticker and warning are shown below.

AMD’s product warranty only applies to HD 6990 graphics cards operated under the default configuration (830MHz GPU clock), and does not cover damages caused by running the HD 6990 graphics card in the overclocked toggle position. Consequentially, AMD will not warrant or accept RMAs for HD 6990 graphics cards which have been overclocked, or where the yellow warning sticker has been removed or otherwise tampered with.
