3080 with Vertical GPU mount

As most people know if you use a riser cable that supports PCIE 3 instead of 4, you have to set the PCIE signal to 3, otherwise it doesnt really work. I for example get a black screen (no picture). My 3080 works flawlessly and I lost 0% performance between normal mode and using the vertical mount. I decided to update my BIOS just now to one that has AGESA 1.1.9.0, and check out the improvement, but guess what? I forgot it resets everything, including the PCIE setting. Now I have to re open my PC, place the GPU normally just to enter the BIOS, change PCIE to 3, and add the vertical mount again lol

This is a heads up for whoever has a vertical mount like me, or is thinking about it. Anywys happy New Years peeps.

I've heard that the vertical gpu kits from Coolermaster and Cablemod add a few centimetres to length of the card; I don't suppose you can report on your experience?
 
I recently got the Linkup Gen4 PCIe riser from rainforest, as I did a water loop and then cleared my CMOS - inadvertedly borked my rig (as it cleared my PCIe Gen3 setting, which I forgot to re-enable) and didn't fancy taking apart my newly assembled loop to directly connect the GPU in to rectify it.

Result! Works perfectly and boots in Gen4 mode properly, get 2gb/s higher bandwidth than direct for some reason using 3DMark's PCI-E bandwidth test. Thought worth sharing with anyone looking for a Gen4 cable :) It was best part of £60 odd though.

I read on the below link that you will nevertheless get worse performance with the PCIE 4.0 cable then having it set to run at PCIE 3.0. Have you compared them?

I have bought the 4.0 cable too so was a little bummed to see this!

@Nitefly I've gone mainly from my PCI-E tests in 3DMark... I got a slightly higher bandwidth throughput.

But also in-games I see no difference in FPS at all. Works spot on imo!

Glad to know it works :)

The main point is to have a vertical GPU of course so if you want to get vertical, you need some form of cable!

I’d be really interested to hear your results if you want the usual 3dmark score test with the same cable in 4.0 and 3.0 modes. I’ll do the same eventually when I build my rig and will report back!
