TL;dr - Anyone with Threadripper or Ryzen hardware still seeing stability problems? Specifically with PCIE errors.
Long version - Between motherboards, power supplies, SSD's and Video cars I've now spent several thousand upgrading to a 1950x, yet still getting hardware problems.
Example errors:

My concerns are twofold - Getting to the root cause and warranty should this turn out to be hardware related. Trying to find answers from vendors is an exercise in futility. I don't do Windows, at all. I don't even own a pirated copy. Disabling the AER is not an option either since the hardware is throwing errors for a reason. Neither is increasing
Something else odd is they appear to change in frequency based on where the hardware physically is. Maybe RFI / shielding problems?
Hardware:
Ryzen Threadripper 1950x (16 core)
Asus ROG Zenith
2x Samsung SM961 NVMe
2x Samsung Pro 960 SSDs
4x 3TB WD Reds
1x EVGA 1080TI/FTW3
32G DDR4
1x EVGA 1kW Supernova P2
4.13.9 Kernel.
Also tried with and still freaking own - the AORUS board, different RAM, Pro 950's, EVGA 850W PSU, EVGA 1080TI Kingpin (returned due to coil whine. Should have kept it as the FTW3 had whine too. Though there was nothing else wrong, replacing the powersupply fixed it. EVGA wouldn't comment on why).
Basically a beast.

and what stability issue?
i havent had any issues since april of this year, after few bios versions that fixed all this.
longest uptime has been 15 days only, but i do reboots to update kernel, so i really haven't kept the system going for longer periods.
im on 4.13 as well
Ryzen 1800x
Asus Rog Crosshair VI Hero
PCIe NVME drive
Nvidia GTX 1070

Take a look here, maybe its something with Nvidia 1080 cards?

Good luck
Regarding the geforce URL, it's broken. Spent 20 minutes filling out capchas to no avail. NVIDIA uses Incapsula on their a lot of their sites which breaks them all... and although they use Google anyway, it's only THEM.
I'm guessing the link is like everywhere else, telling people to disable PCI memory mapping (the pci=nommconf), or dropping back to gen3 PCI. Neither are _really_ options. FWIW gen2 does make the errors go away which furthers my suspicion it's a hardware problem. Given the thousands people have spent I'm guessing hardware vendors will not be opening that can of worms.

For you case I think if you add these kernel parameters in Grub you should be fine :)
