Last week, we brought news from our Tom's Hardware Germany team's discovery that MSI was overvolting the GPUs on the GTX 660 Ti and GTX 670 Ti Power Edition boards (Google Translate) to achieve a higher and longer lasting GPU boost state by basically circumventing the PWM controller.
MSI commented on our report with the following statement:
We are currently not aware of any other vendor providing this same level of performance and we’ve worked with NVIDIA to ensure that new production models will limit this free overclock boost you currently get. Our new production models with normal GPU Boost function will be on sale next month.
Following up, MSI issued a further statement on its website with the following three points:
1. MSI respects the result which is tested by Tom's Hardware, but we have much confidence and believe our products would not cause any customer RMA concerns.
2. Since MSI designs these custom products with overclocking in mind, we "supercharge" these cards because we're anticipating enthusiast to overclock. Because of this design decision and the higher component quality, we're able to provide more power to the board resulting in higher and longer GPU Boost operation without reducing the lifetime of the graphics card or warranty term.
3. MSI's all graphics cards including GTX 670 and GTX 660 Ti passed strict test and stand behind our products with a 3 year warranty.
