ASUS GeForce GTX 980 Strix 4GB OC Review
GTX980.jpg


Today we are reviewing NVIDIA's latest high-end single-GPU graphics card based on the company's new Maxwell architecture, the GeForce GTX 980.


The GeForce GTX 980 is powered by the 28 nm GM204 graphics processor silicon with shader count of 2,048, 128 texture units and the ROP count is a massive 64, with a 256-bit bus connecting 4 GB of GDDDR5 memory.


We like to thanks ASUS for providing the gaming edition of GTX 980, the ASUS GTX 980 STRIX DirectCU II OC (STRIX-GTX980-DC2OC-4GD5) video card for testing.


With a custom PCB, all dark design and the DirectCU II cooler the STRIX hits a modest 1178MHz Base Clock and 1279MHz for its average Boost frequency, with temps reaching upto 70C with low noise levels. And with bundled GPU Tweak tool one can reach close to 1450 MHz on the card very easily.


Now let’s see what this ASUS GTX 980 has for us.


Features
ASUS Strix GTX 980 gaming graphics cards packed with exclusive ASUS technologies, including DirectCU II for cooler, quieter and faster performance for incredible action gaming, and 0dB fan technology for light gameplay in total silence and Blu-ray movie playback that’s free from distracting background noise. Strix GTX 980 features exclusive ASUS DIGI+ voltage-regulator module (VRM) technology and 10-phase Super Alloy Power components for enhanced durability and cooling. Strix GTX 980 has 4GB of high-speed GDDR5 video memory.



  • 1279 MHz Boost clock for better performance and outstanding gaming experience.
  • DirectCU II with 0dB Fan Technology 30% cooler. Silent gaming -
    Exclusive DirectCU II cooling technology outperforms reference designs with an exclusive 10mm heatpipe that transports 40% more heat away from the GPU — a first for the industry! The design also includes 220%-larger heat-dissipation: this means performance that’s 30% and three-times (3X) quieter than reference for ultra-stable hardcore gaming with very low noise. And Strix ups the ante still further with 0dB fan technology that lets you enjoy games like League of Legends® and StarCraft® in complete silence — because the fan stops completely when the GPU temperature remains below a set level.

  • DIGI+ VRM with Super Alloy Power 30% less power noise and 2.5X greater durability. -
    Acclaimed DIGI+ VRM has been applied via a 10-phase power design that uses digital voltage regulators to minimize power noise by 30%, enhance power efficiency by 15%, widen voltage modulation tolerance, and improve overall stability and longevity by 2.5 times over reference.

ASUS Strix GeForce GTX 980 is pretty large in dimensions than the Nvidia reference card. Don’t forget 10mm extra height due to the massive 10mm heatpipe.

Inside
Removing the cooler reveals five heatpipes, two 6mm, two 8mm and one massive 10mm. The center three (ie. 2x 8mm & 10mm) makes a direct contact with the GPU core. Heatpipes are connected with an array of aluminum fin stack and two 92 mm Everflow 12v 0.50 amp fans (Model:T129215SU) for cooling.

Component Layout
Detailed PCB layout of ASUS Strix GeForce GTX 980 shows that ASUS equipped this card with a ten phase digital power design. The GPU gets its current from eight phases and the two phases left, take good care of the 4GB of GDDR5 memory. Once more, ASUS is using high quality super alloy chokes. On the backside of the GPU you can find dedicated SAP CAPs to maximize overclocking headroom.

Temperatures
Room Temperature: 30C
In idle, the temperature is slightly higher though, which is due to the fact that the ASUS GTX 980 STRIX completely stops the fans while running idle. Full load running 3D Mark Fire Strike temperature was real good and fans were slight loud.
