Xalius and I have both taken a look at the schematics and agree that the extra components on the RX3 pair shouldn't be there.

Glad to hear that once you removed them, things started working as epected and that it fixed your devices! Nice find!

We will pass this on and hopefully have it fixed for the next release.

Good Morning,

Has there been any official word on an engineering change to fix this?
I've seen the ECN posted for the original revision of the board to fix 3.3v to PCIe.
I understand this would be a bit more involved, but I think it deserves the attention.

PCIe is really twitchy on the rockpro64.

I've just conducted surgery on my rockpro64 and did the following:
Removed R89508, R89509, R89510, and R89511.
Jumpered across R89506 and C50007.
Jumpered across R89506 and C50007.

This effectively makes RX3P/N as if they were electrically the same as the other RX data pairs.

PCIe performance is improved with 4x+ cards, and it is more stable.
