Hi.
I have this rig:
ASROCK X370 TAICHI
NVIDIA 1050 TI 4GB (running @pciex 3.0 X8)
16GB (2X8GB) DDR4 3200MhZ (HYPERX)
1X M2 NVME SSD SAMSUNG 950 PRO 512GB (HYPER M2 SLOT)
Nvme drive is running @pciex 3.0 X2 instead of pciex 3.0 X4.
Manual says "Hyper M2 slot on AM4 APU (bristol ridge) run at pciex 3.0 X2"- "Hyper M2 slot on Ryzen CPU (Summit Ridge, Raven Ridge, Pinnacle Ridge run at pciex 3.0 X4"
So, why my NVME M2 is running at X2?
What's going on?

Yes, i would say (M2_1) for pciex 3.0 X4 should be running with the 2400G.
Which bios version is on the board (5.10 should be fine)?
And check the M2 mounting and connectors.

Hi.
Bios up is 5.80 (latest).
I put the drive on a m2 to pciex card (3.0x16) in the second pciex 3.0 slot... Same as before, nvme running at x2...
Newer bioses can do weird things like this???
Can I downgrade bios with no pain? I'll keep bios downgrade as last chance, i wanna try all before doing...

I meant at least Version 5.10 should be used.
Did you run some speedtest?
The drive can make up to 2500 MB/s read and 1500 MB/s write.
If it is in the near of these values (> 2000 rd, > 1000 wr), i would say everything is ok and only the pciex 3.0 X2 info is incorrect reported.
Which tool are you using for showing the M2 PCIe setting?
Samsung Magician (should show correct infos)?
Some tools doesn't show PCIe configs correctly.
AIDA for example showed wrong infos in older versions, Version 6.20.53 now is correct (on my board with my NVME drives).

Hi.
Crystaldisk Mark read values are near 1600mb/s.
I'm using Samsung Magician, Aida64 and Hwinfo: all these tools report link speed as pciex gen. 3 x2.

I know Raven Ridge has fewer pci lanes.
Also, with ryzen apu, gpu cards run at 8x (instead of 16x) as mine.
Can this affect m2 slot link speed???

I don't know if this restriction is because of using the GPU card.
Because of the mainboard without video ports you cannot test it without...
And i even can't understand why you are using this board/CPU combination.
Just one idea:
Under Bios Advanced\AMD PBS you can check PCIe settings.
Somebody using a GPU card with Raven Ridge and NVME M2 should post his experience.
Did you contact the Asrock support?

I made a a mistake... I believed that Taichi had graphic port... After holydays my plans are to buy a zen 2 cpu (ryzen 5 2600), meanwhile i should solve this mistery...
Thanks for the tip, but I already comb through every bios line, there's no option for select pciex link speed, only gen. 2 or 3...
