AMD Radeon HD 7970 Quad CrossfireX: The Stock Air Cooling Champion

Armed with only our fists, we slayed the murderous fire breathing dragon and rescued the princess (actually the last HD 7970 to complete our 4-way quadfire feature). This time, we have also included 5760×1080 Eyefinity tests in Battlefield 3 and DiRT3, complete with videos!

Test Setup:

This time we've upgraded our CPU cooling to a XSPC RX360 kit and clocked it higher at 4.8GHz (LinX 4gb 10 runs stable). Unfortunately we still couldn't get any of the available overclocking tools to set voltages or core clocks beyond 1125MHz on simultaneously all 4 cards without running into BSODs or weird artifacts, so we were forced to use the restrictive AMD Overdrive to run our cards @ 1100/1500MHz

The Tests:

3DMark 11 v1.03 Extreme Preset (http://3dmark.com/3dm11/2480832)


3DMark 11 v1.03 Performance Preset (http://3dmark.com/3dm11/2480813)


3DMark Vantage Performance Preset (http://3dmark.com/3dmv/3788612)


Unigine Heaven Benchmark (hwbot.org Submission)


LuxMark OpenCL Benchmark Tool (single card scores 19238)
