The Killer 2100 is a short expansion card. It connects via a 1x PCI-Express slot. Remember that 1x will work in any size PCI-Express slot, from 1x up to 16x graphics slots. A black cage protects the card. There are no fans cooling the board’s tiny processor. A little ‘K’ logo for the Killer NIC is on the slot bracket near the Ethernet port.
There’s really not much to the exterior of the card. Even from the top, here, installed, there’s not much to look at.
Installing the Killer 2100 was not a problem, neither hardware nor software. I downloaded drivers from Bigfoot Networks‘ web site, knowing that even with a fresh product release, there’s likely to be updated drivers available. My ASUS M3A32-MVP has four PCI-Express slots, and I only use one currently.
I didn’t take any screenshots of the driver and software installation process, as it takes several minutes, as promised. Don’t expect to do anything else while it’s going on. It slows the computer to a crawl while flashing the card and sounds were distorted. A reboot was necessary to activate the card. My advice? Go grab a beer, play a rousing game of Beirut, and return to a fully installed Killer NIC.
