Supermicro SuperO C9X299-PG300 Motherboard Review

ATTO Disk Benchmark

The ATTO disk benchmark is a Windows-based utility for testing storage performance of any storage drive or controller. We use the default benchmark setup.

M.2 PCIe Performance

For M.2 testing we use a Toshiba OCZ RD400 256GB M.2 PCIe NVMe SSD.

M.2 performance was good, the drive was able to operate at full speed and it didn't throttle at all – staying sub-60 degrees Celsius even after extended testing runs.

USB Performance

We test USB 3.0 and 3.1 performance using a pair of Transcend SSD370S 512GB SSDs in RAID 0 connected to an Icy Box RD2253-U31 2-bay USB 3.1 enclosure powered by an ASMedia ASM1352R controller.

USB 3.0 and 3.1 performance was par for the course.

SATA 6Gbps Performance

For SATA 6Gbps testing we use an OCZ Trion 150 480GB SSD.

SATA performance was typical of the SATA III interface with only minor testing variance between all X299 motherboards on test.

Audio

Rightmark Audio Analyser is a freeware benchmarking utility designed to objectively test the performance characteristics of audio solutions. We setup a line-in line-out loop and execute the record/playback test before generating the results report you see below. A sampling mode of 24-bit, 192 kHz is tested where available. If unavailable the closest alternative operating mode available is used and clearly marked.

Audio performance was very good across the range, which goes to show that lots of extra “bells and whistles” in the audio department, such as operational amplifiers and codec shielding, do not necessarily translate into better performance. Supermicro opted for a vanilla implementation of the Realtek ALC1220 codec with ELNA audio capacitors and the results are excellent.
