## Questions & Answers

**Q: What's the difference between the x540-t2 and x550-t2 ?**
A: The X520 and X540 have a PCIe 2.0 x8 interface, which has 32Gbit/s bandwidth.
The X550 has a PCIe 3.0 x4 interface, which has 32Gbit/s bandwidth.

The single-port versions may be used in slower slots: X520-T1/DA1 or X540-T1/DA1 will work in a PCIe 2.0 x4 slot (at 16Gbit/s); the manual says the T550-T1 should work in a PCI 2.0 x4 slot as well, although I haven’t tried it.

**Q: Has anyone actually gotten close to the 10gbps connection speed for this card?  pcie 2.0 has limit of 5 gt/s or about 4gpbs max.  so can it be 10gb?**
A: The card is PCIe 2 with x8 lanes, which is 4 GigaByte per second. 4 GigaByte is the same as 32 GigaBit, so it should handle 10 GigaBit just fine.

**Q: Will this card negotiate down to a pcie gen 3 x2?  i think my only free x4 slot only runs in x2 mode which is why i'm asking.**
A: No, please kindly note that the X550-T1 supports PCIe v3.0 (8.0GT/s) (Compatible with 2.0 and 1.1) X4/X8/X16 Lane, and it does not support X2.

**Q: does this work with windows 11?**
A: I have not gotten it to work with windows 11. The seller says to install drivers 26.7 but those dont work
