ASRock's 5Gbit Journey and the Z270 SuperCarrier

By: Steven Bassiri | Editorials in Motherboards | Posted: Apr 20, 2017 3:03 am

Physical Setup Using a Crossover Solution




I have a small two room office within another larger office. I have a few part-time helpers who help me with everything from running benchmarks to making high-quality 4K videos for TweakTown. I also have a system setup with the Fatal1ty Z270 Gaming i7 that is used for recording, storing, and preliminary video transfer. In my office, I have my computer (Z270 SuperCarrier) where I do the major video editing and content creation, and I need a fast and easy way to transfer data between the two rooms.


The entire office is hardwired with Cat5e, and I don't have the resources or authority to change the wiring. Instead, I realized that two of the built-in ports were on adjacent sides of the wall, and I was able to splice them together with a crimp tool and coupler, to create a direct connection between the recording and production rooms. Once I did that, I lost the ability to connect to the rest of the office's network since the Production room only has one Cat5e port, but the Recording room has two. I then used a Crossover cable from the Fatal1ty Z270 Gaming i7 to the coupled Cat5e port and made a direct connection to the SuperCarrier system.



The recording room also has a dedicated secondary switch used to test out LAN speeds of motherboards and other devices there to be tested. So the Faral1ty Z270 Gaming i7 actually has to connect to three networks, and I was able to do it.




ASUS's XG-U2008 is used as the local DMZ switch for testing systems.




I am so sorry; I just had to show everyone how terribly the IT guys who have worked in this office have been. It's just disgusting, to be honest. However, they did wire up many of the areas with multiple Cat5e sockets, and just like most other offices, they cannot easily replace this cabling because it was put in during initial office construction.



PC to PC Connection Setup in Windows 10




Normally you would use a patch cable to connect different device types together, such as a router and a PC, but when you connect the same type of device together, you use a Crossover cable. The Crossover cable connects the transmitting line of the host to the receiving line of the client and vice-versa. Once you connect the two 5Gbit NICs (you can also use it locally if you have two systems in the same room), all you have to do is turn on "Network Discover" and "File and Printer Sharing" on each machine. You will need to have a password on each PC; it's a rule within the OS. You will be prompted for the password when you try to double click the PC you are connecting to under the "Network" tab on the left side menu of File Explorer.




Once you enter in the credentials of the PC you are trying to connect to, you are then taken to a remote folder on the other PC. If you don't know what your PC is called, you can find it by right-clicking This PC and hitting properties. You don't need to go further. However, I wanted to setup a HomeGroup to restrict some access, and I wanted to bridge all the connections on the hub PC.




To setup a HomeGroup you might need to set the Network Location to Private; you will need to do this if you didn't hit "Yes" on the prompt Windows puts up when you first plugged in your network cables (I always hit no). Once you are private, you can select "Create a Homegroup," but only do this on one PC.




Follow the prompts for what to share; they are easy to navigate. You will then be given a password to enter into your other connected PC(s), enter it, and you will then finalize your home group.




At this point, my main Recording Room PC is connected to the office network (with the Internet) and my Production Room SuperCarrier system. However, my SuperCarrier system needs the Internet. I went ahead and bridged the 5Gbit NIC and the 1Gbit NIC connected to the office network by right-clicking with both selected and selecting "Bridge Connections." Now the SuperCarrier system (in the Production Room) now has Internet, however....




Bridging the connections gave the computer over the Crossover cable in the other room Internet, but disabled internet on the Recording Room's computer (the one connected to the office network). There is a fix! However, it's easier to do before you bridged the connection, you will need to go into the Command Prompt and type "ipconfig /all," where you will get all the information you need (boxed in red).




You will then take that information and manually enter it into the Bridge's IPv4 connectivity Properties. Now, both the Recording Room and Production Room have internet connectivity! I went one step further and added the secondary Recording Room network and WIFI into the bridge. As you can see, the bridge connection now has 7Gbps total of aggregated bandwidth.
