    Sleek 28nm card with GPU Tweak

    • Unique fan design dissipates heat efficiently while extending a graphic card’s lifespan by 25%* through increased dust and particle resistance.
    • GPU Tweak utility helps you modify and tune clock speeds, voltages, and fan performance via an intuitive interface.
    • Acclaimed DIGI+ VRM has been applied via a power design that uses digital voltage regulators to minimize power noise by 30% and enhance power efficiency by 15%, widen the voltage modulation range, and improve overall stability and longevity by 2.5 times longer than reference.
