XG-C100C 10G Network Adapter PCI-E x4 Card with Single RJ-45 Port and Built-in QoS for use with Windows 10/8.1/8/7 and Linux Kernel 4.4/4.2/3.6/3.2, TAA Compliant (XG-C100C)

I installed 3 of these. Of course this is just day one, but some of the negative reviews I read, don't apply at all (at least to me, on 3 different computers... one AMD 2 intel). Some of the reviews that say that this card doesn't initialize and you have to wait, or that it disconnects or drivers are horrible etc... this was a very clean plug and play. I downloaded the latest drivers from ASUS... but popped the cards in 2 windows 10 machines, and 1 windows 11 machine. On the 2 windows 10 machines (which are also intel), it tries to boot from the network card. I tried to disable this in the bios but it still tries, this is annoying because it takes like 30 extra seconds to boot. You can click ESC to skip it but if you have a monitor that doesn't show you what is going on you can assume something is wrong or stop it during boot. I need to figure out how to get it to skip this, I am sure there is a way. Full disclaimer still waiting on my other 10G switches, so I haven't tested them out at full speed yet, but on my1G network they work just perfect like the internal NICs always have.

I installed this on my unraid server to obviously get 10gbps connectivity, hooked it up to an unmanaged 10gbps switch, alongside my desktop so I could move files between it and my NAS at approx 1.25 gigabytes a second (10,000 / 8). Common misconception is that you need cat 6a or at least cat 6 to transfer at those speeds. I'm using a 50 foot cat 5e cable and it works just fine. As long as the distance isn't too much, cat 5e is able to do high speeds. I was running out of pcie slots on my server motherboard so I got an m.2 to pcie slot adapter. Aside from needing to take off the bracket of the NIC, it works perfectly since m.2 is 4 pcie lanes just like this card. Haven't had any issues with this. Only thing I would recommend considering before buying, is that RJ-45 uses more power than SFP+ so if you're just starting to build out your multi gig network, consider looking into fiber too. You can get a lot of refurb or used SFP+ gear online for cheap, and it would probably save you some on your power bill. I sort of regret buying the 5 port 10gbps rj-45 switch I have. I love the speeds, but power is so expensive where I'm at that 24/7 powered stuff makes a difference.

I decided to upgrade my home network, so I can access my NAS faster. Given that I had bought a new switch, this NIC card, and a new NAS, I couldn't easily troubleshoot why I wasn't getting the speed to the NAS or why the Internet was dropping. I ended up swapping out every new component, until I discovered that it was this card that was causing all the issues. Issue #1: I couldn't achieve the transfer speed using iPerf3 test. Issue #2: Internet connection was very slow, and Google Speed Test would not run. However, I was able to use the card to transfer files from my NAS to my PC at 1GB/s, which is very close to 10Gbps. If I needed this network card just for internal transfer, then I would've been ok. But, I also needed this card for my Internet access, and that's where it was a no-go for me. I switched out to Intel X550, and without changing anything else, my Internet connection is working fine. I had read some other comments stating that CAT 7 cables are causing problems, but I am only using CAT 6A cables to the Internet. I also upgraded the firmware to the latest, but it didn't help. I do wonder if the card is dropping IP addresses when the buffer is set 'incorrectly.' Either way, after having spent a lot of hours sweating over how to make this card work, I finally gave up and returned the product. Intel card is 3 times more expensive, but I am glad that it just works. I have an ASUS motherboard, which is working very well, so I am a bit disappointed by this experience.

Awesome 10G network adapter. Quality built and great price. Easy to install and setup. I highly recommend this network adapter to take the place of most basic desktops since they usually come with only 1G Ethernet adapter.

I bought 3 of these to upgrade from a 1Gb network to a 10Gb network. They're connected with CAT 6a cable to a Netgear XS-505M switch. 2 of the PC's are Windows 10 with nVME drives and the 3rd is a Windows 7 with traditional hard drives (platters) in a RAID5 configuration. I didn't install the Asus drivers, but instead used the drives from the actual chip manufacturer - Aquantia. I did that after reading various reviews where people were having trouble with the Asus drivers while the Aquantia ones worked just fine. Installation was as simple as it gets. I anticipated that I may have to tweak some of the TCP/IP settings to get these cards to run at their peak performance. But I didn't. Using the default values I am getting 1.1GBs (880Gbs) between the 2 PCs that have nVME storage. I know that many reviews state they're seeing lower speeds and I wonder if it's due to a bottleneck with their storage? When I copy files to the Windows 7 PC with the RAID5 traditional drives the transfer rate hovers around 260Mbs. It's the slower rotating style hard drives that are the bottleneck. One other strange behavior I noticed was that if I plug the Asus C100C card into a 1Gb switch I don't get very good performance. As an example when using my PC's motherboard's 1GB port I get a steady 110Mbs. But when using the Asus C100C connected to that same 1Gb switch It starts out at 110Mbs and then slows down to around 30-40Mbs. I never figured out why. But, when connected to the 10Gb Netgear switch it works just fine. As for the longevity of this card, only time will tell.

This card works very well but has some hiccups. It could just be my network specifically, but it sometimes fails to obtain an IP address after windows start up, and is only solved when restarting my desktop. Otherwise, i haven't experienced any lag or packet loss while using this card, previously i had terrible lag and packet loss on my motherboard's integrated Ethernet until i installed this. Would recommend.

Got this for my HexOS (Truenas Scale) nas machine. Plug-n-play. Just a little configuring to use the other nic port and youre golden!

La carte utilise son propre drivers à l'inverse du modèle Tx401 qui utilise directement le driver du fabriquant. JE ne sais pas si c'est cela qui est en cause mais une fois la carte installé dans le pc avec le driver d'ASUS, au prochain arrêt/Démarrage, il y a un conflit avec le CPU empêchant le pc de démarrer. JE n'ai pas rencontré le problème avec la carte TX401

Great hardware. Performs well at 10gb. Installing on Windows10 was simple! This is a repeat purchase.

Produto recomendo 😁!

Hatte zuerst gar keine Verbindung zum Internet mit dieser Karte. Hab dann eine Suchmaschine bemüht und ein User der das gleiche Problem wie ich hatte hatte in einem PC Forum bereits diesbezüglich nachgefragt. Die Antwort die er erhielt. Man muss im Gerätemanager auf Netzwerkadapter dann entsprechenden Netzwerkadapter auswählen dann auf Eigenschaften und dann auf Erweitert. Dann wählt man Energy Efficiency aus und stellt dort von enabled auf disabled. Jetzt läuft es bei mir ohne Probleme und mit super Speed.
