Sapphire PC-AM2RS790GX Pure 790GX Motherboard Review



To test the Sapphire PC-AM2RS790GX Pure motherboard, I will be running a series of benchmarks designed to push the components to the limits. These tests will include both scientific and video based benchmarks to give us an all around idea of the board's performance. I will then compare the Sapphire 790GX to the Gigabyte 790GX based motherboard to see where it stands among the chipset. To keep the tests as fair as possible, all hardware will be run at stock speeds, timings, and voltages. This will take out any variables that might interfere with the scores.


Testing Setup AMD CPU's:


Comparison Motherboard:

  •   Gigabyte GA-MA790GP-DS4H



Overclocked settings:

  • Processor: AMD Phenom II X4 940 @ 3.571GHz (210x17) 1.55v
  • System Memory: Mushkin Redline PC2-1000 @ 840MHz (5-5-5-12)

To overclock the Sapphire 790GX, I chose to use the BIOS first to see what I could get out of it. I slowly raised the voltage while increaing the multiplier until I no longer could boot and remain stable. Once I reached the maximum on the multiplier I started raising the BUS speed 1MHz at a time. The Sapphire 790GX did not like me pushing the BUS speed very far. In fact, I could only get an extra 10MHz out of it before I could no longer boot successfully. The final overclock I could reach was 3.571GHz, which is a bus speed of 210 with a multiplier of 17x and a voltage of 1.55v on the core. I also wanted to see if I could push it anymore using the AMD Overdrive utility, however I could not squeeze any more juice out of her.
