ASUS 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 (XG-C100C)

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.

Windows 10 installation was seamless.Linux (Ubuntu server 16.04) was a pain. Only method ended up being through "insmod atlantic.ko" see below for details.Performance so far (connected PC-to-PC without a switch), has been flawless. I am connecting over 150 feet of cable & can transfer four hard drives at full speed without any discernible bottlenecks. highly recommend the card!----------------------------------Ubuntu server 16.04 installation:1) clean install of Ubuntu 16.04.2) install the build-essential package from apt3) download the Asus 5.0.0.5 driver for the XG-C100C to /home/USER , unzip the file to reveal the Atlantic1.5.348.0.tar.bz2 archive, and then unpack it: tar -xvjf /home/USER/Atlantic1.5.348.0.tar.bz24) Navigate to the new /home/USER/Atlantic directory and run: make , which should then generate an "atlantic.ko" file.5) Once you have that file in place (check!), edit the network interfaces file: sudo nano /etc/network/interfaces , and set the static IP for your card (in this case, it occupied the enp1s0 slot, you'll need to check which slot it sits in) something like the following:- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -auto enp1s0iface enp1s0 inet staticaddress 10.10.10.20netmask 255.255.255.0- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -5a) to do a temporary installation, run: sudo insmod /home/USER/Atlantic/atlantic.ko (this will only last till a reboot). This should bring the card to life & you can test.6) To finalize your installation (so the driver will persist after a reboot), run: sudo nano /etc/rc.local , and edit your rc.local file to include insmod /home/USER/Atlantic/atlantic.ko , below the #!/bin/sh -e at the top of the file, and above the exit 0 at the bottom something like the following:- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -#!/bin/sh -e#etcinsmod /home/USER/Atlantic/atlantic.koexit 0- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -Nb. In my setup, the computer this linux server connected to had a static IP set to 10.10.10.10/255.255.255.0 and it was connected directly pc-to-pc with an ordinary cat6 cable.Nb. For the above installation, if you use your home/USER directory for other items, you might want to place the Atlantic driver in a different directory than this one...

We have been using these cards in our builds for a couple of years. Starting about 6 months ago we noticed that if you turn the computer off and then back on the computer will not boot. There are two workarounds to the issue. Either completely remove power from the computer before booting the computer back up each time or replace the NIC card with one made by a different manufacturer. We contacted Asus about the issue and they sent us a new NIC car but the new card has the same issue. I found that the tp-link TX401 uses the same chip on their board but does not have the issues seen with the Asus cards.

Finally an affordable 10GbE card. I actually replaced a dual port Intel 10 GbE with this. The Intel card frequently overheated, while this one doesn't. No issues with Win10 or Linux support, and it's having no trouble hitting expected transfer rates.This card also supports 2.5/5 Gbit rates, as well as directly attaching to another 10GbE card. You don't need a 10GbE switch to use it. Also, if you're using CAT 5e/6, I strongly suggest at least CAT 6A. It is the same price but is more stable for higher bandwidth.[Edit - 2/2021 - Windows update]Aquantia was acquired by Marvell in 2019. ASUS does not appear to be keeping their Windows drivers up to date, so you should just get them directly from Marvell (search for AQC107 drivers on Marvell's site and you'll find both firmware and windows drivers). This can be applied to any AQC107 based NICs.[Edit - Linux info]For a bit of background, this card, as well as the Gigabyte GC-AQC107 (10GbE Network Adapter Pci-E X4 Card with RJ-45 Port) and manufacturer Aquantia AQtion 10G Pro NIC use the same Aquantia AQtion AQC107 chipset. The only mild difference between the cards is the size of the heatsink, so pick whatever looks like the best option. In Linux, the driver for this is called atlantic. This driver was added to the default Linux kernel as of version 4.11. That means that it is baked in to Ubuntu 18.04 and later.And for those wondering about sustained transfer rates/overheating, I've done iperf3 testing and am able to transfer at a continual average rate of 9.37 Gb/s for at least 10 minutes.$ iperf3 -c host -t 600Connecting to host giver, port 5201[ 4] local 192.168.3.244 port 33486 connected to 192.168.3.152 port 5201[ ID] Interval Transfer Bandwidth Retr Cwnd[ 4] 0.00-1.00 sec 1.09 GBytes 9.40 Gbits/sec 488 844 KBytes[ 4] 1.00-2.00 sec 1.09 GBytes 9.39 Gbits/sec 254 1000 KBytes...[ 4] 598.00-599.00 sec 1.09 GBytes 9.38 Gbits/sec 413 1.01 MBytes[ 4] 599.00-600.00 sec 1.09 GBytes 9.37 Gbits/sec 127 1.10 MBytes- - - - - - - - - - - - - - - - - - - - - - - - -[ ID] Interval Transfer Bandwidth Retr[ 4] 0.00-600.00 sec 655 GBytes 9.37 Gbits/sec 184641 sender[ 4] 0.00-600.00 sec 655 GBytes 9.37 Gbits/sec receiveriperf Done.
