I'm trying to work something out. I'm sorry, I know these types of questions come up a lot - but the workings of PCIe lanes is really confusing
So anyway. I have (of what I think is relevant):
And this is fine.
My motherboard documentation states, for PCIe slots:
2 x PCIe 3.0/2.0 x16 (x16 or dual x8)
1 x PCIe 3.0/2.0 x16 (max at x4 mode)
3 x PCIe 3.0/2.0 x1
Now I was told by someone (can't find a reference) that in this configuration, I am using all of my 24 PCIe lanes (where does that number come from?) - 16 lanes for the 2080ti, and 4 lanes for each of the M2 drives.
Is this true?
What I wanted to do, was slot in a 10 Gb card:
- ASUS XG-C100C (PCI-E x4)
But according to my friend, this won't work due to lack of lanes. Or at best I would degrade the performance of my 2080ti.
Can someone shed some light on this, please?
