10GB network interface that also accommodates 2.5GB usage
10GB network interface that also accommodates 2.5GB usage
Hello everyone, welcome to the forum! I’m just starting out and would really value your advice. I’m currently assembling my own router with a Dell OptiPlex that has an i5 9th Gen processor—though I think it might be a bit too powerful for the job. While researching, I found many discussions and videos recommending Intel network cards. My setup has a 2.5GB internet connection, and I’m trying to make my network more capable by choosing a 10GB NIC. However, I’ve noticed that most 10GB NICs only support speeds up to 100MB, 1GB, or 10GB, which doesn’t quite match my needs. Since my switch runs at 2.5GB, it adds another layer of complexity. I’ve looked into upgrading the switch, but most options are quite pricey—some cost over $200. The NICs that fit this configuration are around $200 or higher. Could anyone suggest a more affordable option? Any recommendations would be really helpful.
I personally rely on this NIC without problems. https://eshop.macsales.com/item/OWC/PCIE10GB/ Also worth mentioning, most 10GB NICs usually accommodate 2.5GB as well, even if not stated. It's typical for backward compatibility all the way down to at least 1GB.
Absolutely incorrect. The Intel X540 isn't suitable; consider cards featuring Intel X550 or Aquantia AQC107/AQC113 chipsets. These support 10GBASE-T and NBASE-T (2.5G, 5G).
Thank you for the clarification. I should note that it needs dual RJ45 connections. Regarding backward compatibility, my findings indicate it only supports the standard speeds—100 MB, 1 GB, and 10 GB—not higher speeds since it doesn’t negotiate beyond those limits.
Great to hear that! You're welcome! Let me know if you need anything else.
Avoid the AQC107, as a Windows Update caused it to fail completely and many reported crashes when under stress. Some say it overheats, but I’ve seen it run smoothly in Linux, suggesting the issue might be specific to Windows. No one has mentioned problems with the AQC113 so far.
