System IO Benchmarks


CrystalDiskMark SATA6G:




CrystalDiskMark M.2:





CrystalDiskMark USB 3.0:




ixChariot Network Throughput:




Overall storage and networking performance is quite good and consistent with what I expect from Z170 motherboards. The Z170 OC Formula is one of few Z170 motherboards with three M.2 ports. To RAID the M.2 ports, each port needs to be switched with two SATA6G ports, meaning all the SATA ports from the Intel PCH are disabled when all the M.2 slots are filled. It also means that all SATA and half the M.2 bandwidth for each slot is routed through a quick switch, which inherently introduces a tiny bit of latency for SATA testing.


Audio RMAA 5.5:


I disable all audio features, set the correct bit rates, and then test the audio with a loopback test.




Sound Judgment by Ear: Very Good. Audio quality is high and the amplifiers boost is noticeable. There are 5 ratings for audio: 1. Problems, 2. Okay, 3. Acceptable, 4. Very good, 5. Excellent
