I Want to upgrade my network To 2.5 Gigabit
Im buying this switch https://www.qnap.com/en/product/qsw-1105-5t
I found this 2.5 Gigabit Nic https://www.delock.com/produkte/1451_PCIe/89019/merkmale.html
But i'm not sure the motherboard in my "server pc" is backwards compatible
the Nic is a PCI Express x1, V2.1 , but the motherboard only supports PCI Express x1, V2.0
im not sure that this nic is backwards compatible ???

Link to the old motherboard : https://www.gigabyte.com/us/Motherboard/GA-F2A85X-D3H-rev-10/sp#sp

should work fine. cards are supposed to auto-adjust to whatever the slot is.

I think the speeds on that nic in a v2.0 x1 slot is going to be about 500 megabits, so not full GBE let alone 2.5gigabits
Correct me if I am wrong.

It's 500MB not 500Mb for pcie2.0 x1 so it's like 500MB*8=4000Mb, so should be fine. (y)
