Asus STRIX B350-F GAMING, EVGA SuperNOVA G3 650 W 80+ Gold, Ryzen 5 2400G, Samsung 970 Evo 500 GB M.2-2280, G.Skill Trident Z RGB 16 GB F4-2400C15D-16GTZR, CyberPower CP1000PFCLCD UPS, Asus Radeon RX 560 - 1024 4 GB STRIX (asus rog-strix-rx560-o4g-gaming), RCA 24" Class FHD (RTDVD2409)
BIOS 5402, Windows 10 v1903, AMD Chipset driver 1.8.19.0915, Adrenalin 2019 Edition 19.9.1, ummm RGBs are blue. Can't think of anything else lol.
The purchase of the RX560 was supposed to be the final piece of a decent budget build.
I shut the machine down, turned off the power supply, waited for indicator lights to die, unplugged the power supply, held down the power button to make sure it was completely drained. I removed the CMOS battery, then jumped the clear pins. I installed the card which went fine. Hooked up the 6pin VGA harness, and reinstalled CMOS battery. Plugged in, powered on after taking the HDMI cable out of the integrated port and put to the card’s HDMI. Posted, went into bios, everything default. Went to graphics card POST menu and it says that the card is on Native x8, not x16. Extremely bothersome… I happened to take a look at EZ mode because I haven't looked at it since before last BIOS update, and noticed that it said I have nothing in the M.2 slot!! I've been a tech for several years, I wouldn't be asking for help if this was an easy fix. I am open to, and appreciate any advice or guidance.
SSD that I have been using for weeks did however show up in boot menu thank goodness. I Blew out the system for fresh windows install- setup. Cleared all partitions on the 970SSD and installed windows 10 from fresh media creator on another machine with a 32GB usb 3.0 key. Went fine, super fast. The last time I had the most success with I actually decided to plug into the network so I could do updates first. (Goes against my teaching and experience, usually always do chipset, audio, video at least then plug in and update.) But I got decent results. I installed the drivers I listed above and a few of the other minor ones. Stable, installed Elder Scrolls Online. Not blown away by performance improvement. If my RX560 is running at PCIe 3.0 x8 instead of x16 am I at 50%power? Grrr, I am hoping That having my M.2 SSD isn't taking lanes or somesuch away from my PCIe 3.0 x16 video card in the PCIe 3.0 x16_1 slot.
 
ryzen apu only have x8 pcie
is not 50% power. rx 560 is not high end enough to worry about it.

"AMD Ryzen™ with Radeon™ Vega Graphics /7th Generation A-Series/Athlon X4 Processors
1 x PCIe 3.0/2.0 x16 (x8 mode) "
Just saw that the 2400G has 12 lanes total! wth...
So on reading that with expansion slots... I was looking at maybe upgrading to a 2700x, but with the B350-f is the mobo gonna bottleneck? From what I am seeing https://en.wikichip.org/wiki/amd/ryzen_7/2700x The 2700x would give me 20 lanes(1x16+1x4 ) on PCIe revision 3.0.
 
NVMe SSDs do not appear within the BIOS until Windows creates the system partition with the EFI Boot Sector.

M.2 NVMe installation guide is found in this thread:

I have windows installed on my m.2 nvme, was able to install it just fine with USB, but it shows as a boot option in bios but on the section for the drives it says nvme m.2 is empty.
