ASUS EAH6850 DirectCU OC Edition Review



Temperature testing will be accomplished by loading the video card to 100% using MSI Kombuster which is paired with MSI's afterburner overclocking utility for temperature monitoring. I will be using the stability test set to a resolution of 1920 x 1200 using 8xAA. I will use a 15 minute timeframe to run the test ensuring that the maximum thermal threshold is reached. The fan speed will be left in the control of the driver package and video card's BIOS for the first test, with the fan moved to 100% to see the best possible cooling scenario for overclocking. The idle test will be a 20 minute cool down with the fan speeds left on automatic.

  • GPU Stability test in MSI Kombuster
  • 15 minute load duration
  • 15 minute idle duration
  • Temperature measured in degrees Celsius













Lower = Better


At the default test levels, the DirectCU cooling solution on the ASUS EAH6850 was just about the coolest running card in the pack. Only out-cooled by the GTS 450 and HD 5750. When you crank up the voltage tweaking ability in ASUS's Smart Doctor, the cooler has a hard time keeping up with the thermal loading generated by the test when both the clock speeds and voltage are bumped up. Most manufacturers say that the kinds of power loads that Kombuster/Furmark/OCCT generate cause unrealistic loads that even the most stressful games do not generate. So, to test that hypothesis, I went ahead and looped the Crysis warhead benchmark through a ten run set using the 1920 x 1200 test resolution 8x AA and the Gamer preset in DX10 mode. What I found was that the game pulled a higher power consumption number and generated temperatures that were within two degrees of the load temperatures delivered by the EAH6850 DirectCU as when running the Kombuster application.
