No drops, no renegotiation issues. * **Multi-gig support** Handles 2.5 / 5 / 10 Gb speeds properly with auto-negotiation. * **Standard drivers (Windows/Linux)** Works out of the box on Windows 10/11 and modern Linux kernels (AQC113 support is built in). * **Great for direct attach** I’m using it NIC-to-NIC (no switch), and latency is extremely low (~0.2 ms). --- ## ⚠️ Things to know * **Runs warm** Like most 10Gb cards, it gets hot. Make sure you have airflow. * **Driver quirks on niche systems** Works great on standard PCs, but on locked-down systems (like Synology DSM) you may need manual driver binding. * **Cable quality matters** For 10Gb, use good Cat6a or better. Lower-quality cables can limit speed. --- ## 💡 My setup * Direct 10Gb link between PC and NAS * MTU 9000 (jumbo frames enabled) * Dedicated subnet (no gateway) Result: * ~9.9 Gbps throughput * ~0.2 ms latency --- ## 🚀 Performance note If you’re not seeing full speed, it’s usually not the NIC—it’s: * disk speed (HDD RAID will bottleneck) * SMB/file copy limitations * CPU or driver settings The NIC itself is capable of full throughput. --- ## 👍 Final verdict **Pros** * Excellent performance for the price * Reliable once set up * Works well on modern systems **Cons** * Needs decent cooling * Not truly plug-and-play on every platform --- ## 🧾 Bottom line If you want an affordable 10GbE upgrade and are comfortable with basic setup/tuning, this card delivers full performance and is a great buy. For plug-and-play enterprise environments, you might look at Intel/Mellanox—but for most setups, this does the job perfectly. Review: Great little NIC - No fuss with windows 11. Installed the card and it just works. Purchased the 2.5gb model and speeds are as advertised. I also like the black finish since I have a black case and motherboard. Very inexpensive card. I can’t speak to the longevity of the product since I haven’t had it that long. ## Features - [Super-fast 2.5Gbps Networking] High up to 2.5x-speed with Realtek RTL8125B chip, much faster data-transfer speeds for gaming, living broadcasts and downloads in bandwidth-demanding tasks. - [Complete Compatibility] Seamless backward compatibility for 2.5Gbps/1Gbps/100Mbps, Support Windows11/10/8.1/8/7, MAC OS and Linux, no dirver needed on Windows10, easily download the driver in Realtek official website for other OS. - [PCIe to 2.5G RJ45] This 2.5GBASE-T PCIe Network Adater convers a PCIe slot(X1/X4/X8/16) into a 2.5G RJ45 Ethernet Port.

Installed the card and it just works. Purchased the 2.5gb model and speeds are as advertised. I also like the black finish since I have a black case and motherboard. Very inexpensive card. I can’t speak to the longevity of the product since I haven’t had it that long. ### ⭐⭐⭐⭐⭐ It's a Little inconsistent *by J***N on September 14, 2022* Out of the box this was not running at the 2.5Gb speeds (even though Windows reported it as running 2.5Gb) it was staying around 900mb with iperf3 test between 2 other machines on network that both have 2.5Gb NICs. Using the QNAP 2.5Gbe unmanaged switch for 3 PCs that all have 2.5Gbe NICs. They are segmented on their own VLAN coming from pfsense firewall appliance which also has 2.5Gbe. After updating the drivers from the Realtek site as per the pamphlet that came in the box along with a small form factor screw driver and 2 screws (using case screw to match black aesthetic) and the 2 I/O plates, then it unlocked the full menu in the interface's controller properties. Also was getting closer to the 2.5Gb speeds on local network, RDP feels smoother and stable connections without drops. There is some irregularity in the iperf3 tests though. Not getting the irregularities from 3rd PC to main PC so not sure if it's driver related or just an issue with the Realtek chipset of this card. Overall though satisfied with the price to performance and hope there will be future driver updates, not counting on it though. For what I need it to do, be a stable RDP connection it seems to be holding strong and helps not feel laggy like it did with the default 1Gb port on the X370 Taichi Mobo. This is an improvement. If you do want a blacked out PCB and the bright green LED isn't visible while doing work then this is a good 2.5Gbe card. Also make sure you get the latest driver from Realtek, out of the box is not fully unlocked.
