VGA Hotwire

Quick hardware-level voltage tuning

DIY modification of voltages on MATRIX HD 797 becomes simple by removing the need for complicated and risky soldering. Just connect wires from dedicated headers on compatible ROG motherboards to VGA Hotwire connectors on MATRIX HD 7970, after which you can change voltages directly on the hardware level through the ASUS UEFI BIOS or via the Windows-based Ai Suite II. TweakIt

Instant voltage adjustment

TweakIt provides flexible overclocking control even when gaming or running benchmarks! The + and - buttons put overvolting adjustments at your fingertips, with more power translating into the faster and smoother gaming you crave and the winning edge you require for intense multiplayer and competitive benchmarking. DIGI+ VRM with 20-phase Super Alloy Power

Precise digital control enhances performance, reliability, and card longevity

MATRIX HD 7970 is built with carefully-designed massive 20-phase power delivery. This ensures ample room for experimental performance tuning, as its DIGI+ VRM digital voltage regulation design augments precision overclocking capabilities, which are further supported by the use of hardened Super Alloy Power capacitors, chokes, and MOSFETs. These components are forged under extreme pressure and temperatures to increase reliability, power output, and overall card lifespan while eliminating bothersome choke buzzing noise. GPU Tweak

The world's first quad-focus graphics overclocking tool with new loadline calibration and VRM overclocking

Easily fine-tune core and memory clocks, voltages, and fan settings intuitively via sliders or manual value entry. MATRIX HD 7970 arrives with a new ROG edition of GPU Tweak, which adds detailed GPU loadline calibration and VRM frequency tuning, allowing for the most extensive control and adjustment parameters for maximum overclocking potential.
