    Independent IGP memory can reduce the consumption of system memory.

  • 3DMark Vantage
    The 3DMark Vantage is the newest benchmark software which is from Futuremark Corporation and generally used on analyzing a PC performance of DirectX® 3D visualization, especially a valuable guideline for gaming users as reference.
    Hardware equipment required: [CPU] AMD Phenom 9850(2.5GHz), [Memory] DDR2 1066(1GBx2)
    Software equipment required: [Benchmark] 3DMark Vantage, [Resolution] Entry Mode (no AA, no AF, 32bpp),[OS] Windows Vista 32-bit.

  • Easy OC Switch
    Help end-users upgrade CPU FSB directly
    Buy an essential CPU but want to reach higher performance
    Skip the complicated BIOS OC setting and enjoy the higher level CPU performance

  • DrMOS
    Excellent energy-saving capability and offers high-computing performance.
    Provide superior energy-saving function and maintain an ultimate low temperature operation.
    Comes with three incredible features.

  • All Solid Capacitors
    Longer lifespan than electrolytic capacitors
    Endurable to operation under higher frequency & temperature
    Avoid exploding capacitors to cause mainboards failure

  • All Shielded Choke
    A choke is an inductor responsible for storing power and regulates the current.
    All shielded choke could reduce core power loss, lower EMI interference.
    Store energy longer at higher frequency, achieving higher efficiency.
