Crashing issue due to pci-e gen

Mr Mcgoo · 2025-12-21T15:49:35+0000

So i have an rtx 5090 running at x16 4.0 due to using a 4.0 riser however my new 4tb nvme is 3.0. since my new drive was put into the top slot (cpu pcie lanes used) i have been having issues with random crashing. is it possible that the 3.0 nvme is having issues while the cpu slot is set to 4.0?

Get rid of the riser. They often cause nothing but trouble it seems.

this riser has been working fine until my new nvme was installed.

Remove riser, fit GPU into the PCI-E slot, see if it still crashes. If it doesn't then the riser was the problem in combination with the NVME

Does it help if you set the PCI Gen of the GPU slot to 3.0?

Maybe this is a red herring and the new drive is just.... broken?

I will first remove the riser and see if the issue is fixed then try running in pci-e 3.0 if the riser removal didn't fix the issue.

I'd try running PCI-E 3.0 first, because you don't have to do anything except change one setting in the BIOS.

I wouldn't call using a PCI-E 5.0 GPU at 4.0, working fine. I take it, it's from a previous build?
Get rid of it

I bet it works fine then

i decided to get a gen 5 riser instead of messing about with gen 4 on a gen 5 card and board just to hopefully rule out such shennanigans lol

But you'll miss out on all the fun :cry:

ive got a gen 4 riser cable actually as well if i get board il plug that in instead swap with the gen 4 gpu thats in the gen 4 pcie slot go completely backwards just for the fun of it yeah? lol
see if i can connect it via some kinda ghetto usb 2.0 adaptor into the slowest usb socket i can find on the pc ........

Run it at 640x480 with 16 colours.

so i put my cpu into 3.0 and issue is fixed. Just removed my riser and put to 5.0 and issue reared its ugly head. starting to think my nvme is the issue. now going to move my nvme into the chipset m.2 slot and see if that fixes my issues. if so i will install the riser again and see if that works at 4.0 again until i can get a 5.0 riser as they are so expensive and as i have the arctic storm 5090, the vertical mount looks nice in my system so will get a 5.0 riser soon as they are very expensive

Don't bother, just mount it horizontal like a normal person

Put the money saved towards a DDR5 ~~mortgage~~ upgrade

Hope you get it sorted dude

Will you be able to rise the challenge though?

Or lower your expectations it'll work?

Sorry to hear that, but at least you've found the issue, this means you can probably use your riser again, right?

It's a shame but it happens. Riser installed and working fine
