GLOTRENDS ST7419 4-Port 2.5G RJ45 Network Card with I226-V Controller

Put inside a 920x mini PC. Add a 8x2.5gb switch Add a Unifi U7 Pro Better firewall/router/AP reliability, speed, and concurrency than any sub $1000 appliance can provide, for a grand total of ~$440. Throw in a few moca 2.5 adaptors and you can easily spread 2.5g whole home easily. I have a fast enough Internet connection to saturate the uplink port and ~100 networked devices across the house. No issues at all with the NIC, none whatsoever. Doesn't drop like the Intel 225/226 sometimes do, so a good implementation of the chip. Auto detected in pfsense, Ubuntu, and windows. Stable ping to my nearby speedtest.net server of 16 +/- 4ms. Stays nice and cool in a tiny PC. Win. Win. Win.

Honestly, this Intel i226-V NIC has been nothing but trouble. I tried using it with pfSense and it constantly dropped connections, threw watchdog timeout errors, and would randomly kill my WAN link until I manually reset it. I updated firmware, tried every driver and setting tweak out there, and even reinstalled pfSense from scratch, and tried 3 different motherboards with no luck. As soon as I swapped it for an older Intel i210, or a Realtek, yes a Realtek worked over the intel, everything worked perfectly. Bottom line: it just doesn’t play nice with pfSense or FreeBSD right now. Save yourself the headache and skip this card. Update, had issues with windows 11, server 2019, server 2022 and server 2025 built in drivers and intel specific drivers. This card is a flop.

Extremely poor performance in Proxmox VM. Throughput in the double digit Mbps initially, up and down, with unstable latency from ~30ms to nearly 1s. Disabled IOMMU in bios and both latency and throughput improved. Now running ~600Mb down and ~500Mb up, still not up to expectation but at least usable. If you're looking to use this in a virtual environment I would not recommend it at this point. You're going to get similar performance from a 1G 1000VT at a significantly lower price. I havent run it outside a virtual environment so I can't give an opinion on it's performance there.

Have to manually add drivers for server 2025, but automatically installs in 2022, win 11, no prob. Card stays static, adapters don't reinstall randomly, allowing you to assign VMs to them no prob.

Great purchase for a 2.5gb Intel card. Looking at the ports with heatsink facing up, port 0 starts on the left and port 3 is on the far right.

Great value for a quad 2.5 GBE network card. Fits perfectly in a micro form factor PC. Excellent for use in a firewall OS.

Gave me issues with proxmox had to send it back..

J'écris peu de commentaires sur Amazon mais pour une fois, je pense que mon retour d'expérience sera utile à d'autres. Cette carte réseau (version 4 ports I226-V) aurait pu tenir toutes ses promesses mais en fait non. La raison est que cette carte, une fois que les options PCIe passthrough et IOMMU sont activées sur votre système d'exploitation, n'offre absolument pas le niveau de performance attendue: - gigue importante - ping élevé - débits n'excédant pas 200 mbits/s Le problème est hélas connu mais sans possibilité de le régler (même en désactivant l'ASPM) ; vous pouvez rechercher sur votre moteur de recherche préféré: "high latency issue i226-v" et constater que même une mise à jour du firmware ne réglera rien. Cette carte pourrait fonctionner correctement en bare metal mais honnêtement, ce modèle loupe sa cible de marché et nous sommes en 2025, pas en 2005. Visiblement, soit l'implémentation des puces i226-v sur la carte n'a pas été faite correctement soit le design des puces a été bâclé mais force est de constater qu'il est plus judicieux de recommander une alternative sur base Realtek RTL8125B qui sera plus fiable (impensable d'écrire ceci il y a 10 ans !). Cette carte ST7419 est clairement à éviter.

This quad 226 card is a nightmare to use in a Linux Proxmox OS. While it is detected correctly and the link speed is 2.5Gb, the actual performance is totally inconsistent, stuttering intermittent hangs. Even pings on the same switch reached 1000ms. It’s all caused by the way the 226 chipset handle interrupts. It floods the cpu with interrupts crippling performance. The 226 was never meat to be used in a quad interface. Absolutely avoid if you are doing any type of virtualization.

Out of the box this was unusable. I was getting 50-500ms pings with this device to a directly connected device (should have been < 1ms). There was a telltale linux kernel log: # pcieport 0000:07:00.0: invalid VPD tag 0xff (size 0) at offset 0; assume missing optional EEPROM The GLOTRENDS card seems to lack a configuration EEPROM (cost cutting/quality?), causing PCIe timing issues and completion timeouts under the motherboard’s default power/perf settings. This is why 50ms+ of latency were added to pings which should be sub millisecond. I have tried forcing the pci slot to PCI3 speed in the bios, and added pci=pcie_bus_perf to the linux boot parameters. but these didn't shift the needle. There seems to be a fundamental flaw with the pci switch in this device. If I find any workarounds I'll update this review. further notes: The description states PCIE3 however in the model I received the chip they're using to switch between the 4 i226v chips is only a PCIE2 chip. 07:00.0 PCI bridge: Pericom Semiconductor PI7C9X2G608GP PCIe2 6-Port/8-Lane Packet Switch

速い、安い、安定している、... 普通に良い商品で、追加購入の予定

Piètre qualité, ne fonctionne déjà plus ! acheté le 23 avril 2026, ne fonctionne plus depuis le 20 juillet 2026 ! Produit de piètre qualité, la carte ne fonctionne déjà plus et bien entendu le délai de rétractation est écoulé ! A éviter sauf si vous souhaitez perdre de l'argent inutilement.
