Q: Does Windows require driver installation?

A: Yes.

Q: What are the requirements for the Ethernet cable?

A: Cat6e or Cat7.

Q: Does this network card support PXE diskless boot and WOL (Wake-on-LAN) network wake-up?

A: It supports PXE and WOL network wake-up.

Q: Why can't I achieve 10G speeds no matter how I test it?

A:

1、Check if the Ethernet cable is Cat6/7.

2、Ensure that the driver is up to date (you can download the latest driver from here).

3、Verify whether the network settings have enabled Jumbo Frames.

4、Check if the switch/gateway device can reach 10G speeds.

5、Test whether the hard drive uses the NVMe protocol (the hard drive read speed should be higher than the network transfer speed).

6、When using iperf3 for testing after enabling Jumbo Frames, use multi-threaded mode.

7、In Windows, check if the network card setting is 10G. Method to set the network card speed: Right-click on "This PC" -- Manage -- Device Manager -- Network Adapters, find the corresponding device, then right-click on Properties -- Advanced -- Speed and Duplex -- Value.

Q: Can this card achieve full 10G speeds on a PCIe 3.0 bandwidth?

A: The speed is around 7 - 8Gbps. It requires a PCIe 4.0 bandwidth to achieve full speed.

Q: Why is the file transfer speed from my Windows 10 computer to my NAS only a few hundred megabits, while the speed from NAS to Windows can reach around 1G?

A:

1、Confirm that the negotiated rate at both ends is 10Gbps full-duplex.

2、Use iperf3 to test network throughput to rule out storage impact./

3、Check the storage write speed, especially the NAS write performance. You can transfer a large file from another device to the NAS to observe the speed. If the NAS write speed itself is insufficient (e.g., a mechanical hard drive in RAID5), it may be the bottleneck.

4、Check the SMB protocol version and encryption settings.

5、Update the driver.

6、Adjust TCP/IP parameters and Jumbo Frame settings./

7、Disable software or services that may affect performance, such as antivirus software and firewalls.

For example, if iperf3 tests show that both directions can reach close to 10Gbps, then the issue may lie in the storage write speed. Conversely, if iperf3 shows asymmetric network speeds, you need to check the network configuration.
