Testbed Configuration

We performed all our tests on a testbed built with the following components:

  • ASRock FM2A85X Extreme6 rev.1.03 mainboard (Socket FM2, AMD A85X, BIOS version 1.70);
  • AMD A10-5800K processor (3.8-4.2 GHz, 4 cores, 100 W, 0.825-1.475 V, FM2);
  • AMD Radeon HD 7660D integrated graphics (800 MHz, 384 ALU, 32 nm, DirectX 11);
  • 2 x 4 GB DDR3 SDRAM Corsair Vengeance CMZ16GX3M4X1866C9R (1866 MHz, 9-10-9-27 timings, 1.5 V voltage);
  • Kingston SSDNow V+ Series (SNVP325-S2, 128 GB, SATA 3 Gbps);
  • Noctua NH-D14 CPU cooler;
  • ARCTIC MX-2 thermal interface;
  • Enhance EPS-1280GA 800 W PSU;
  • Open testbed built using Antec Skeleton system case.

We used Microsoft Windows 8 Enterprise 64 bit (Microsoft Windows, Version 6.2, Build 9200) operating system, AMD Chipset Drivers version 13.1, AMD Catalyst graphics card driver version 13.1.

Unfortunately, even before we got down to test the ASRock FM2A85X Extreme6, our Crucial m4 SSD (CT256M4SSD2, 256 GB, SATA 6 Gbit/s) had failed. It had worked in our testbed configurations for just over a year. It died suddenly while the computer was working at default settings and ceased to be identified by the BIOS. We had to replace it with a Kingston SSD Now V+ Series (SNVP325-S2, 128 GB, SATA 3 Gbit/s). We also updated our drivers and replaced our Enermax NAXN ENM850EWT power supply with an Enhance EPS-1280GA. With the testbed configuration changed that much, we couldn’t use the data we obtained in our testing of the ASUS F2A85-V PRO and Gigabyte GA-F2A85X-UP4, so we had to retest their performance and power consumption.

Compared to our earlier tests, we could see a performance hit (over 1%) in Adobe Photoshop CS6 because it took longer to load and save the four 24-megapixel images (about 10 MB each). And we also noted an improvement (over 1%, too) in Hitman: Absolution, which must have been due to the driver update. Otherwise there were no notable changes in performance whereas the new PSU turned out to be more economical than its predecessor.
