## Overview

The ASUS XG-C100C is a PCI-E x4 network adapter delivering ultra-fast 10Gbps speeds with full backward compatibility across multiple Ethernet standards. Featuring a single RJ-45 port and built-in QoS, it supports Windows and Linux OS for flexible, high-performance networking—perfect for professionals demanding seamless, high-bandwidth connectivity.

## Description

The ASUS XG-C100C uses fully backwards compatible, next-generation 10GBase-T (10G) networking technology to deliver speeds of up to 10Gbps –10x faster than standard Gigabit Ethernet. It enables ultra-fast 10Gbps network access for desktop PCs, so you can easily handle the most data-intensive tasks in your office or at home. Disclaimer: Actual data throughput and WiFi coverage will vary from network conditions and environmental factors, including the volume of network traffic, building material and construction, and network overhead, result in lower actual data throughput and wireless coverage.

Review: So far no issues except annoying network boot - 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.
Review: Works great in unRAID - 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.

## Questions & Answers

**Q: Would this work with a crossover cable, so you can avoid the (ridiculous) expense of a 10G switch if you wanted to connect only two PCs together?**
A: The TP-Link TL-SX105 5-port 10Ggps is available now in late 2021 at a not quite so ridiculous expense of $320.

**Q: Will i get 10g speed over pcie 2.0?**
A: PCIe1 is 250MB/sec per lane, PCIe2 is 500MB/sec per lane, PCIe3 is 800MB/sec per lane.  So an x4 PCIe2 slot has..... 2Gb/sec transfer capability.  10gbe is 1.2Gb/sec transfer speeds, which falls nicely within a PCIe x4 slot.  If you're computer can drive data that quickly is another question.  A single consumer SATA SSD can only do 400-500MB/sec , and SATA3 can only do 600MB maximum, which is under the speed of the 10gbe.  So unless you have a RAID setup with SSDs, you cannot exceed the ethernet connection.  Or, a nice NVMe m.2 drive can do 3600MB/sec easily, which will hurt the 10gbe connection.

**Q: can this work as a 10gigabit connection in between 2 systems if both have one of these like from a file server to a workstation pc**
A: Yes. That's exactly how I'm using a pair of them, between a Linux file server and desktop. I manually configured IP addresses and routes.

**Q: Is this card low profile? does it come with the low profile bracket?**
A: The card comes with a standard size bracket but a low profile bracket is in the box.

### ⭐ Did not work out - here is what I ended up doing
*by A***R on January 29, 2021*

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.
