Footnotes
  1. AMD product warranty does not cover damages caused by overclocking, even when overclocking is enabled via AMD hardware
  2. There are 64 lanes of PCI Express® Gen 3 connectivity in the AMD Ryzen™ Threadripper™ CPU. 4x lanes are reserved for communication with the AMD X399 chipset. Up to seven PCIe® devices may be connected to the system (not to exceed 60 lanes); additional concurrent devices may be supported with a PCIe® clkgen on the port or device. An additional 2x PCI Express® Gen3 lanes within the AMD X399 chipset may be used by the motherboard vendor to provide an additional 4x SATA or 2x SATA Express connections.
  3. These 8x PCIe® Gen2 lanes in the AMD X399 chipset may be utilized by the motherboard vendor to enable expansion devices such as Ethernet, WLAN, Bluetooth, or other companion controllers.
  4. Testing by AMD Performance labs as of 12/21/2017 on the following system. PC manufacturers may vary configurations yielding different results. Results may vary based on driver versions used. System Configs:  AMD Ryzen 5 1600X, GA-AX370 AORUS Gaming 5 motherboard, 16GB of dual-channel DDR3-3200,  Graphics driver 23.20.768.0 (17.40), and a Seagate Barracuda 500GB boot drive.  When Enmotus FuzeDrive was enabled,  a Samsung 950 PRO NVMe drive was added to the drive pool. Without enmotus FuzeDrive for Ryzen, the system took 28.611 seconds to complete a boot to windows via explorer; 21.421 seconds to initialize SMSS; 2.274 seconds to initialize the Windows Logon; 56.04 seconds to launch adobe premiere; 59.27 seconds to launch adobe photoshop; and 85.09 seconds to launch DOOM. With Enmotus FuzeDrive for Ryzen enabled, the system took 10.534 seconds to complete a boot to windows via explorer (28.611/10.534=272%, or 172% faster); 3.926 seconds to initialize SMSS (21.421/3.926=546%, or 446% faster); 1.461 seconds to initialize the Windows Logon (2.274/1.461=156%, or 56% faster); 8.27 seconds to launch adobe premiere (56.04/8.27=678%, or 578% faster); 5.75 seconds to launch adobe photoshop (59.27/5.75=1031%, or 931% faster); and 38.77 seconds to launch DOOM (59.27/38.77=219%, or 119% faster).
