Integrated Device Testing

Audio Subsystem Testing

Audio Playback Testing

Using a selection of Hard Rock and Heavy Metal music tracks and Windows Media Player, the audio subsystem playback performance was tested for playback accuracy and fidelity.

Listening tests using the selected audio tracks were performed with a Razer Carcharias audio headset as well as a 5.1 speaker setup to exercise the subsystem's audio fidelity. There were no distortion issues using either setup with sound reproduction coming though clearly. Oddly enough, sound reproduction was better with the Sonic Studio enhancements enabled with the 5.1 speaker setup, while quality suffered when enabled using the audio headset.

Microphone Port Testing

For testing the board's Microphone input port, the microphone from a Razer Carcharias audio headset was used to capture a 30 second spoken phrase with the assistance of the Microsoft Sound Recorder application. The resulting audio file was saved to the desktop and played back using Windows Media Player.

Even though the recorded audio remained distortion-free at all levels, audio pickup sounded muted until Microphone Boost was set to +20dB with recording volume set to 75. Sound pickup was enhanced yet negatively modified slightly with the Sonic Studio tools active, however.

ATTO Disk Benchmark

To validate that the board’s device ports were functioning correctly, we connected an OCZ Vertex 460 240GB SATA III SSD to the system and ran the ATTO Disk Benchmark against the drive. The SSD was directly connected to the native SATA 3 ports. NGFF port testing was performed using an M.2 based Plextor PCIe M.2 2280 128GB SSD. The M.2 device was tested in the integrated M.2 slot (located just below PCIe x1 slot 1). ATTO was configured to test against transfer sizes from 0.5 to 8192 KB with Total Length set to 512 MB and Queue Depth set to 10. The M.2 SSD selected for testing has a maximum read throughput of 770 MB/s and a write throughput of 335 MB/s over a PCI-Express x2 bus. The selected SSD has a maximum maximum read throughput of 540 MB/s and a write throughput of 525 MB/s on a SATA III controller. The drive tests were repeated three times with the highest repeatable read and write speeds recorded.

Devices on all ports performed well within expectation with the M.2 SSD overcoming the SATA read speed barrier because of its enhanced PCIe-based bandwidth.

SoftPerfect Research NetWorx Speed Test

In conjunction with Windows Performance Monitor, SoftPerfect Research NetWorx Speed Meter application was used to measure the upload and download performance of the motherboards integrated network controllers. Speed Meter was used to measure average network throughput in MB/s with Windows Performance Monitor used to measure average CPU utilization during the tests.

The LanBench network benchmarking software was used to generate send and receive traffic between the local and remote systems over a five minute period with packet size set to 4096 and connection count set to 20. A LanBench server was set up on the remote system to generate or receive traffic for the tests performed. The upload and download tests were repeated three times with the highest repeatable average throughput and the lowest repeatable average CPU utilization percentage recorded.

Note that that theoretical maximum throughput for a Gigabit Ethernet adapter is 125 MB/s (1.0 Gbps).

The Intel GigE NIC performed as expected with fill upload besting that of download by an average of 9 MB/s, at the upload speed average 117 MB/s. The CPU utilization was higher than expected during download tests, averaging 17% instead of the much lower 4% during upload tests.
