PCIe 3.0 riser cable issues?

[Abaris]

Hello, everyone!

 

A little bit of context:

I am running a Core i7-14700KF with a Z690 chipset MOBO paired with a MSI 3070 slotted in a 4.0 16x port. Running a freshly installed Windows 11.

 

I upgraded from a Z170 chipset and Intel 6th gen CPU. The GPU was not upgraded which was slotted to a PCIe 3.0 16x slot with an EK Riser cable -I assume the riser is also 3.0, but cannot be 100% sure-.

I was also using Windows 10.

 

Now I am noticing that playing Final Fantasy XIV at 1080p will max out my GPU utilization to 99% most of the time, and playing a video on a secondonitor at the same time will start to stutter and run very poorly probably because utilization is at 99%.

 

This didn't happen before the upgrade. And doesn't happen with a second similar setup before the upgrade.

 

I made sure I have the latest drivers.

 

Can a PCIe 3.0 riser cable connected to a PCIe 4.0 slot be the culprit?

 

How can I be certain that the cable os indeed a 3.0 one?

 

Thank you!

Sorry, but your post is a little difficult to read for people that have their page set to the "dark" mode.  Makes it a lot easier on the eyes for a lot of people like myself.   The only thing that I could read normally was the Thank you! at the end of the post.  Sorry.

 

Take care and good luck.

In the motherboard BIOS go into your PCIE settings and force your PCIE into gen 3 instead of Auto. 

A gen 3 riser between gen 4 components will cause weird issues.

Sorry about that. Just copied from another browser and didn't notice. Fixed it!

That makes a lot of sense! I forgot you could do that in the BIOS. I'll try that! Thanx.

I can't the custom watercooling loop will not let me... Well I can, but ot will be A LOT of trouble and time to test without it.

why not?

always keep a few barb fittings and soft tubes, to either test card in different configuration or remove it entirely..  

and to easier drain, a drain valve at the top and bottom of the loop. i have a stop valve too.. to easier drain each side of the loop.
