Intel X520-T2 10Gbit cards failing to function in Windows 10 X99 Deluxe Build
I purchased two Intel X520-T2 cards with 10GBit ports for my Ubiquiti 10Gb switch, but they only operate at 1Gb. The Device Manager reports everything is fine, while Task Manager shows it’s paused. I removed and reinstalled them after downloading the latest drivers from Intel 26.4. I’m unsure what to do next.
Alex, thank you for your update. I had a hectic day balancing work and school, but I managed to run the test you recommended. I connected a USB with Ubuntu and booted from it. The system recognized the drive as 10 Gb, and when writing to a local SSD, I achieved around 450 MB/s from my Synology server. This suggests there’s no hardware problem. I also verified the switch connection, which displayed 10Gb, while Windows showed 1Gb and performance was capped at 1 GB. Have you tried checking the switch port settings or testing with a different cable?
I'm using an Intel X550-T1 NIC on a Windows 10 system right now. It's a newer card, but I don't remember needing any special Intel drivers. Windows automatically downloaded the latest driver. Just had to turn on jumbo frames for it to run at 10GbE. Make sure jumbo frames are enabled. On a X99 platform, it's likely fine, but verify there are sufficient PCIe lanes available. Lower-end CPUs like the 5820K have fewer lanes compared to higher-end or Xeon models. The motherboard might have the slots, but the CPU must support them. Typically, 10GbE needs four lanes.
DogKnight, your setup looks solid but tricky. With the RTX2070 and those cards, you're pushing performance limits. The 28/40 lanes might be tight depending on your configuration. Your US-16-XG and USFXG are great for boosting speed, but you're still missing a few pieces to fully optimize it. I understand how frustrating it is when progress feels stuck—don’t lose hope, just keep exploring solutions.
Yes, you can increase visibility by optimizing your post with relevant keywords, engaging visuals, and sharing it on multiple platforms.
Sharing your post on the thread places it at the top. Be sure to follow forum rules while doing this. It looks like you have sufficient PCIe lanes. Some boards may block certain slots or lower available lanes if others are occupied. Double-check your motherboard manual for details on PCIe lane allocation.
Dog Knight, I've tested the card in multiple slots and it functions smoothly at Gigabit speed on Windows. I've also run it on Linux, and everything works correctly. This means the problem isn't with the hardware, motherboard, or PCIe lane.
It looks like you're running low on ideas. This might be a software problem based on what you've shared. Cross-posting your steps from other forums could help. The Home support might also be useful. Good luck resolving it!
