Asus Crosshair IV Extreme AMD 890FX Motherboard

Article Index:   
Our two AMD test systems were configured identically save for the necessary difference in RAM type and speed due to their differing chipsets. Both systems were equipped with 6GB of RAM. The M3A78-T board used DDR2-800—this 780GX-based board has never been fond of DDR2-1066. The Crosshair IV Extreme used Corsair DDR3 rated for 1600MHz but we purposefully backed down to 1333MHz which is the highest, officially supported speed of the 890FX chipset.

SiSoft Sandra 2010 SP1
Synthetic Benchmark Performance

We began testing with SiSoftware's SANDRA, which stands for System ANalyzer, Diagnostic and Reporting Assistant. We examine a CPU's multimedia and arithmetic performance using Sandra, as well as the motherboard's peak memory bandwidth. The difference between the two platforms should be minor given their identical configurations.





Sandra shows precious little difference between the two motherboards. The one exception is the memory test, where the Crosshair IV Extreme has an obvious advantage.
