ASUS XG-C100C PCI Express 10-Gbps Ethernet Fiber Network Adapter, backward compatible with 5/2.5/1 Gbps and 100Mbps, built-in QoS

Worked immediately in my Linux PC, with 64 CPU, no drivers needed ~ lan was the bottleneck Make sure the short slot on your motherboard is PCI3 and not PCI2, sometimes a short slot will be downgraded to a PCI2 by the manufacturer while all the other longer slots are PCI3. You can of course put it in a longer slot to obtain PCI3 and that's exactly what I have had to do and move one of my cards down to the PCI2 short slot - it's a USB 3.1 Type C card and still has ample bandwidth to provide 10Gbits to my external hardware even though it's now in a PCI2 slot. Before you complain of slow throughput consider where the data you are transmitting is being stored, if it's a standard spinning HDD then they max out between 200~250Mb/s, SATA SSD or SATA NVME maxes out at 500~600Mb/s, mine goes to PCI Bus mounted NVME in PCI3 mode ~ which in my system max out at 2GB/s, that's 2 GigaBytes / s, not 2 Gigabits / s, generally speaking if a measurement is in Gb/s it's Giga bits ( small b ), if its GB/s its Giga Bytes ( capital B ) but not everyone sticks to this convention. Rule of thumb - MegaBytes/s are approx 1/10th of the Gigabits, keep that in mind and the speeds in your system are easier to envisage.

I have ASUS BQ16 and BT10 routers that have 10GbE RJ45 ports, so it would be appropriate to have an ASUS 10Gb Ethernet v3 card for each of two Windows computers. They are an easy fit provided that the driver is found in ASUS UK download site. However, although the download includes a Utility file - presumably for the Quality-of-Service (QoS) the app doesn't install in Windows 11, to allow manual changing of the QoS. There is a driver download for Linux too. The card build quality is excellent, and the red finish would look great with glazed side panel on a computer case. The photo shows one of the Windows computers with 10GbE send and receive. There is a slight discernable speed difference when opening files or websites, compared to the 2.5GbE NICs that the 10GbE replaced. Whether it's worth paying for the slight difference may be questionable. I have 500MbE FullFibre from BT, and I note that the hub info. quotes 1000MbE send and receive.

Its a little strange but yes, ASUS produces one of the cheapest 10GbE RJ45 out there and here it is. Just like other consumer grade 10GbE NICs, this is an Aquantia AQC-107 cards, which had recently fall under the Marvell umbrella - which is quite a big name in corporate NICs space. In case you need to know - that's the same chip as Apple uses in their iMacPro and Mac Mini - so macOS has drivers for this chip out of the box. Don't ask me why that matters... Tested in Windows, Ubuntu and unRAID and it records a 9.4-9.5Gbps with iperf using a Mikrotik CRS305, so that's pretty good. Build quality is good as you would expect from ASUS; comes with a half height bracket for swapping, just in case you need to fit it in a 2U rack, or in my scenario, a Lenovo M920q tiny node. I was pleasantly surprised by how small this thing is - the picture makes it looks bigger than it is. If you look closer you'll see that the card finishes by the end of a x4 slot - so that's very short indeed. The real question here is - whether you actually need a RJ45 NIC? If you are buying one of these, presumably you'll be needing a 10GbE Switch. Apart from a couple of 8xGbE+2x10GbE offerings from Netgear etc, most switches are still corporate offerings which primarily focuses on SFP+. So if you buy one of these with a SFP+ switch, you'll need to throw in an extra SFP+RJ module which are like £50-60. Also worth mentioning is that these modules run at 70-90ºC at 3V+ - I kid you not - its not really designed for your desktop use. Then it begs the question - why not use a SFP+ NIC? A Mellanox ConnectX-3 is just <£40 from China, and a SFP+ Patch cable <£20. Then you have a connection costing less than this ASUS NIC while also not being a finger burner. Worth a thought really. Its worth noting that there is a SFP+ equivalent of this card from ASUS too in form of XG-C100F. However while that is priced similarly to its RJ45 sibling, its more than double the cost of other SFP+ competitors. So unless you really need a SFP+ NIC on AQC-107... for some macOS related reasons... then you probably wouldn't want that.

If you are used to adding cards to your PC this is simple to install. You obviously need an empty slot, then just intsall as usual. Windows 10 found it instantly and it worked straight out of the box

As someone has pointed out, this card reports as pci express 4.0 x2 in Windows which is slightly at odds with the description which says pci express 3.0 x2. My motherboard only has a single spare x1 pci express 3.0 slot available with the 2 nvme slots populated, so I'm limited to something like 5.5gb speeds, but that's fine, I knew that was going to be the case. I've tested this in a couple of other systems with the full pci express bandwidth available to it and it reaches close to 10gb in iperf. I've had this working with both Linux and Windows 11 and it was plug and play for both.

Whilst i note some people have had success with this card, most are not trying to use it at the advertised speeds. This is the 2nd card with the same chipset (different model) I have tried and it works for a short while before becoming unresponsive until you reboot. On researching a possible fix it seems many have had similar issues with a wide range of PC configurations so I returned and refunded. Note, I even tried running the card at 5Gig and it still failed. I've since found a better spec'd Intel card for the same price on ebay and have had no issues whatsoever.

Works great with Windows Server once the drivers are installed. Would be better if it was already recognised on an ASUS motherboard without drivers but here we are. Sits nicely in the case, easy to install and get drivers to recognise the card, haven’t tried on Linux or Proxmox yet but definitely want to

This is the cheapest 10GbE ethernet adaptor on the market by some margin, hence the 5 stars. I have used it in both Linux and Windows systems and had no problems so far, the performance is dependant on the PCIe slot though. Intel-based cards may offer superior performance but for home users, this is more than enough. In Windows, you have to install a driver, which is disappointing as everything I have installed in recent times works natively. Therefore I had to leave the original NIC plugged in while I downloaded the drivers etc. In Linux, it was recognised immediately, so I only needed to change the config settings in Netplan.

installed without any issues

Produto recomendo 😁!

I am using this for last 2 years. Actually getting 10g speed. At this cost. Recommended

Here’s an upgraded version with gaming included and a bit more impact: ⸻ I recently added the ASUS XG C100C 10G Network Adapter to my setup, and it has been a huge upgrade for my home network. My motherboard only supported up to 2.5Gb speeds, which was holding me back from fully utilizing my 5Gb internet at home. After installing this adapter, I was finally able to unlock those higher speeds and even surpass the 5Gb mark, which was exactly what I was hoping for. Installation was straightforward and hassle free. It fit perfectly into my system, and the drivers were easy to install. Within minutes, everything was up and running, and I immediately noticed the performance boost. As a gamer, this upgrade has made a real difference. Downloads are significantly faster, game updates that used to take a while now finish quickly, and overall network responsiveness feels much smoother. Latency is stable, and I have not experienced any drops or interruptions during online gameplay, which is huge for competitive sessions. The connection has been extremely reliable across the board. Whether I am gaming, streaming, or downloading large files, everything feels faster and more consistent. It handles heavy network usage without breaking a sweat. Build quality is solid, and it runs reliably without any issues. If you are limited by your motherboard’s network speeds and want to fully take advantage of high speed internet, this adapter is absolutely worth it. Overall, this is a great investment for gamers and anyone looking to upgrade their network performance and future proof their setup.
