MSI’s popular Afterburner software is used to overclock VTX3D Radeon HD 6850 X-Edition.
The frequency of the GPU and the memory is raised in small 10 MHz intervals, and then tested with FurMark 1.8.2. In case of instability or artifacts, the overclock is canceled.
We successfully got 75 MHz more on the core. The memory did not show any signs of weakness before we hit 1190 MHz.
The influence of the overclock can clearly be seen in the 3DMark Vantage and the Far Cry 2 tests.
VTX3D's Radeon HD 6850 X-Edition supports voltage regulations on the GPU via MSI's Afterburner software.
To demonstrate the noise levels, we have recorded to videos. The camera is one meter from the case. RAM and CPU coolers are turned off, and the case’s cooler are set to the lowest RPM settings. Even though the results cannot be written on paper, the videos give a good picture of reality.
The frequencies of the core and the memory are lowered to respectively 300 MHz and 100 MHz, with a cooler fan activity of 34 % in Windows 7.
AMD have called the feature “PowerPlay”. That gives an energy conservation in single and CrossFireX configurations.
GPU-Z shows a temperature of 74 degrees Celsius, and a fan activity of 48 %, under stress in FurMark. The frequencies of the core and the memory are maxed out.
VTX3D Radeon HD 6850 X-Edition is relatively low on noise levels at normal use. There is no doubt about, that the card’s cooler is more effective than AMD’s reference cooler. For everyday use and gaming, the card is most recommended for the picky user.
Side note: If you are looking for a noise free card for your PC, then we recommend taking a look at Gigabytes GV-N460OC-1GI, which is built on NVIDIA’s GF104 core, and equipped with the Windforce cooling unit.
