So much cleaner than my explanation lol]]> Sat, 17 Nov 2018 06:39:18 +0000 https://forum.asrock.com/forum_posts.asp?TID=10194&PID=57978&title=fatality-x470-question#57978 https://forum.asrock.com/forum_posts.asp?TID=10194&PID=57977&title=fatality-x470-question#57977 Author: basedmeezus

I think you probably misread it. The motherboard will offer you 20 pcie 3.0 lanes. 16 get's taken up by your gpu, which leaves 4 pcie 3.0 lanes. those 4 pcie 3.0 lanes is then used by your m.2_1 ultra slot. The chipset I believe has 4 pcie 3.0 lanes dedicated to it, which is used to offer 8 pcie 2.0 lanes. of those 8, 2 are used by the m.2_2 slot.

and yes, you could have 1 m.2 in the ultra slot (m.2_1) which is pcie gen3 x4, and another m.2 in the m.2_2 slot which is pcie gen2 x2]]> Sat, 17 Nov 2018 06:38:03 +0000 https://forum.asrock.com/forum_posts.asp?TID=10194&PID=57977&title=fatality-x470-question#57977 https://forum.asrock.com/forum_posts.asp?TID=10194&PID=57976&title=fatality-x470-question#57976 Author: Xaltar

M.2_1 = PCIe 3.0 x4
M.2_2 = PCIe 2.0 x2

From the user manual.

All this means is that drives connected to M.2_2 will be limited to 10Gb/s vs 32Gb/s for M.2_1. In other words, so long as the drives are listed as supported you should be able to populate both without issue.

M.2_1 support list is on page 44 of the user manual
M.2_2 support list is on page 47 of the user manual

Is the documentation wrong, or am I just not understanding it. The way it's worded sounds different.

Does that mean I could use a PCI-E m.2 in each slot?]]> Sat, 17 Nov 2018 05:08:13 +0000 https://forum.asrock.com/forum_posts.asp?TID=10194&PID=57972&title=fatality-x470-question#57972 https://forum.asrock.com/forum_posts.asp?TID=10194&PID=57959&title=fatality-x470-question#57959 Author: basedmeezus

I just bought a complete system using the ASRock Fatal1ty X470 Gaming K4 AM4 AMD Promontory Motherboard. I am researching m.2 / ultra m.2 and I feel like there is conflicting information on the Motherboard feature page and the manual. Looking at the Newegg feature list of the motherboard it makes this claim about the ultra m.2 slot
M.2 PCI Express module up to Gen3 x4 (32Gb/s)

However on the website, for compatible m.2 cards it says this
Note1: The speed of PCIE Gen3x4, Gen3x2 and Gen2x4 M.2 SSDs can only reach to Gen2x2 when plugging in M.2 slot.

Why get a Gen3 x4 if it will only reach Gen2x2?
