Just wanted throw out this PSA that the combo listed in the subject line simply doesn't work with a PCIE riser. Spent way too many hours trying to figure it out and my system is 100% stable after removing the PCIE riser. My system is now just sitting outside of case till my Sliger 610 arrives. I had my system in a Dan Case A4 (loved it), but all the crashing was unbearable.

What's everyone else's experience been with a riser cable on the new Alderlake CPUs and z690 boards?

edit: Looked everywhere in the BIOS to force back to PCIE gen 3 with no luck

I assume your PCIE cable is Gen 3 (not faulty) and changing the PCIE option to Gen 3 in BIOS doesn't help?

Not an Alderlake user here, but am interested to see if anyone else has the same issues, what's the fault and if there's any solutions.

Can't switch to gen 3 in BIOS (at least I couldn't find the option to switch in the BIOS after a lot of looking). I then purchased a linkup gen 4 riser and my system crashed, just not as often, as when I was running the gen 3 cable.

Yeah, the Gen 3 cable was not faulty as my old build (4770k+Asus Impact Board+3070) worked great on it.

It's common for Gen3 riser to have issues with Gen4 GPUs, hence the recommendation to force Gen3.
Probably similar with Gen4 & Gen5 CPU, look for a PCIe config option in BIOS

This topic is a good reminder how restrictive can be riser for SFF.
Gen 4 riser are not yet fully reliable (some gen 3 too)...and now Gen 5 with Alder lake...by 2022 we will have gen 5 gpu and it will be a mess again.

Yeah I spent months tinkering with different risers for Ryzen 5000 only to end up using a Gen 3 setup. And the biggest irony is that there is no GPU out there maxing out Gen3, so Gen5 appears to be an unnecessary complication…

So far, for GPU, Gen 4 & Gen 5 only inflated prices of MB for no actual usage/advantage for standard consumers.
Already for gen 2 vs gen 3 it tooks years to become barely noticeable (for gamers).
