ATi 6990 Will NOT be warrentied in OC mode!
For die-hard overclockers, I am afraid I have bad news from AMD regarding to their ATi 6990 series. For example, if you tried to remove their warranty sticker (marked as yellow) and flip the switch to position: ‘Position 1’, then your warranty will be void, regardless. Even worse, if you take the yellow sticker off and accidentally run into problems, then it’s going to be an ‘RMA’ disaster.
Notes: I would advise you to use ‘Position 2 (Default)’ and keep the engine at stock level. This is crucial if you want to stay out of trouble and provide longer lifespan for your GPUs. Trust me, there is enough horse-power inside this monster and there is no reason to overload it like a devil.
