Dear All,
Motherboard: Asus Rampage IV Extreme X79
The Asus Rampage IV did not not support PCIe 3.0 out of the box (at least in Windows). The hardware was there but I think it came out just before the standard and could not get certified. In windows you could force PCIe 3.0 via a registry hack, which works on this system and graphics drivers.
Checking my PCIe speeds in Linux using lspci -vv | grep -E ‘PCI bridge|LnkCap’ shows:
PCI bridge: Intel Corporation Xeon E5/Core i7 IIO PCI Express Root Port 1a (rev 07) (prog-if 00 [Normal decode]) LnkCap: Port #0 , Speed 8GT/s, Width x8, ASPM not supported
So it looks like PCIe 3.0 is supported natively in Linux for this motherboard, since the transfer rates show 8GT/s which corresponds to PCIe 3.0. However the Nvidia drivers are only showing PCI Express x16 Gen 2 with Maximum PCIe Link Speed as 5.0GT/s. After doing some digging it appears you should be able to force the Nvidia Linux drivers to use PCIe 3.0, however I’m having no success. What I’ve tried so far:
Created /etc/modprobe.d/nvidia-pcie-gen3.conf
Added options nvidia_470 NVreg_EnablePCIeGen3=1
Run mkinitcpio -p linux513
Rebooted.
Checked Nvida settings, confirmed driver is only detecting PCIe 2.0
I notice there is another file “mhwd-gpu.conf” in the /etc/modprobe.d/ folder, maybe this is conflicting? Any advice or help would be really appreciated! Remember I have used Linux for tow days only, so be gentle with me!

From quick google search, it seems that it is possible to add a Grub parameter to force Gen 3
NVreg_EnablePCIeGen3=1
but not sure about the module name, probably simply nvidia, so the full Grub parameter probably would be
nvidia.NVreg_EnablePCIeGen3=1
Try to boot your system by adding it to your Grub (either by adding it to the Grub config file /etc/default/grub and then issuing an update-grub command, or by adding it directly from the Grub menu, by pressing E key in the Advanced option to edit the proper line) maybe if you want to try it at your own risk as it is only supposition from my quick google search.
I looked into your motherboard manual and didn’t find any relevant config, but this board seemed to be something really special back in the days, with all its features

Dear omano,
Thank you SO MUCH for taking the time to help me. Thanks to your advice I’ve got PCIe 3.0! I really didn’t hold out much hope for getting a reply. The board is pretty cool and it feels good to breath life into it and not consign it to the e-waste dump. It’s actually still pretty fast, and I look forward to tinkering with Linux.
I added the command NVreg_EnablePCIeGen3=1 to the /etc/default/grub file. It needed to be appended to the GRUB_CMDLINE_LINUX_DEFAULT line, which originally was:
GRUB_CMDLINE_LINUX_DEFAULT=“quiet apparmor=1 security=apparmor resume=UUID=01b17930-cc29-4f7c-87b8-e074768a8f79 udev.log_priority=3”,
and changed to:
RUB_CMDLINE_LINUX_DEFAULT=“quiet apparmor=1 security=apparmor resume=UUID=01b17930-cc29-4f7c-87b8-e074768a8f79 udev.log_priority=3 nvidia.NVreg_EnablePCIeGen3=1”
Again, thank you so much for your kindness in helping a stranger.

Just a side note for the future… since @omano solution works…
Early load with kernel parameter: nvidia.NVreg_EnablePCIeGen3=1
Late load with modprobe: options nvidia NVreg_EnablePCIeGen3=1
nvidia is the module/driver, but you requested an unknown module nvidia_470, so that was the reason why it did not work wit modprobe.
